<h3><strong>C.&nbsp;&nbsp;&nbsp;&nbsp;Budget Updates</strong></h3>
<p>Dr. Tromberg gave an update regarding the budget. He noted that the NIH budget proposals from the Senate, House, and the White House for FY25 are roughly the same (approximately $50 billion), which represents slight increase over the FY24 funding level ($48.6 billion). The FY25 NIBIB proposed appropriation in the Senate and the White House proposals are $440.6 million and $441.9 million, respectively; due to the proposed restructuring of NIH in the House bill, NIBIBs budget would be absorbed into a new entity. Dr. Tromberg noted that committee report language specifically recognized the success of the RADx program and commended NIBIBs efforts. As summarized in the May Council meeting, the payline for parent R01 announcements is 16% (21% for new investigators and 29% for early-stage investigators).</p>

<p>RADx Tech: In continuing his discussion of RADx, Dr. Tromberg highlighted the programs first de novo clearance from the U.S. Food and Drug Administration (FDA): a fingerstick hepatitis C diagnostic by the company Cepheid. Dr. Tromberg noted that this rapid test provides results in less than an hour, facilitating treatment with antiviral drugs on the same day as diagnosis. He added that the RADx Tech Independent Test Assessment Program (ITAP) validation core and clinical trial data led to this potential game-changing diagnostic for the roughly 4 million people in the U.S. with HCV.</p>
<p>MIDRC and NAIRR: Dr. Tromberg next gave a brief update on the impact of the Medical Imaging and Data Resource Center (MIDRC), noting that the initiative is continuing to expand. He said Congress is very interested in AI and that NIBIB has participated in three AI-related congressional briefings. Further, NIBIB is involved in the National AI Research Resource (NAIRR).

</ul>
<h3><strong>G.&nbsp;&nbsp;&nbsp;&nbsp;Discussion</strong></h3>
<p>Council asked if there has been any follow-up after interactions with congressional staffers. Dr. Tromberg noted that NIBIB takes every opportunity to promote and publicize the work of this community. He also said that NIBIBs goal is to keep the conversation going with individual professional societies, but continued follow-up needs to be initiated by these societies and individual investigators. He added that NIBIB will continue to create communications and legislative content. Dawn Beraud from AIMBE noted that the congressional event had a record number of staffers and that proactive follow-up from AIMBE occurs after these events. She also added that these events establish NIBIB as a trusted resource and helps to build connections. Council continued this line of thought and asked if there was a plan for a coordinated campaign to deliver NIBIBs message strategically and from multiple angles. Dr. Tromberg said that this issue is something that NIH as a whole is considering, as NIH itself has multiple sub-brands that can pull the messaging in different directions. He noted that the NIBIB strategic plan will be released soon and that future discussions with Council will help shape messaging.</p>
<p>Council applauded the partnership with HBCUs and asked how this program will help shape best practices that can be translated to other institutions. Dr. Avila said that sustainability is important—not just in terms of funding, but also in terms of faculty. He noted that faculty development and long-term support from institutional leadership are key, and that hes hopeful that other NIH institutes and centers will help to build up this program. Council also asked about funding for junior faculty members, noting that while NIBIB may be prioritizing funding for early-stage investigators, renewing their first R01 is challenging, so perhaps the problem is just being shifted instead of being addressed. Dr. Tromberg noted that he is aware of this issue, and Dr. Avila mentioned a funding opportunity specifically for new and “at-risk” investigators (PAR-22-181).</p>
<p>Council concluded their discussion by asking about the 24% cut to non-early-stage investigators and how to balance this with funding for early-stage investigators. Dr. George said that NIBIB is relying on feedback to understand when a cut becomes too harsh, and that another option is to award fewer R01s but with smaller cuts.</p>

<h2>II. NIBIB Staff Presentation: Re-envisioning the Postdoctoral Experience in Biomedical Imaging and Bioengineering - Zeynep Erim, Ph.D., Director, NIBIB Division of Interdisciplinary Training</h2>
<div class="field field--name-field-council-minutes field--type-text-long field--label-hidden field__item"><p>Dr. Erim said the purpose of her talk was to start a conversation about the NIH-supported postdoctoral scholar experience and encourage NIBIB Council members to participate in a working group that NIBIB will establish to assess the postdoctoral experience from its unique perspective.</p>
<p>Dr. Erim provided the context for the NIBIB working group proposal. She mentioned that the NIH Advisory Committee to the Director (ACD) established a working group in 2022 because of these concerns and trends:</p>
<ul>
<li>The effectiveness of the current apprenticeship-based postdoctoral model and how well the current system serves postdoctoral scholars, their well-being, and career progression.</li>
<li>The number of NIH postdoctoral appointments has leveled off in recent years and has declined by 7.6% in FY 2021. This trend may be due to factors such as poor compensation and benefits, job insecurity, and the uncertain prospects of securing a faculty position at the end of their postdoctoral position. The COVID-19 pandemic further exacerbated these challenges.</li>
<li>The data suggests a postdoctoral scholar shortage, which could impact the biomedical research enterprise.</li>
</ul>
<p>The ACD working group was charged with evaluating the status of the postdoctoral training process, understanding fundamental issues affecting postdoctoral scholars, and identifying possible solutions to address these issues. The working group issued its report in December 2023.</p>
<p>Dr. Erim highlighted the key sub-recommendations from the report, noting that there was a follow-up Request for Information (NOT-OD-24-150) seeking feedback to inform implementation of these recommendations, which was highlighted earlier in the Directors report. However, compared to the biological and biomedical sciences, there may be unique factors impacting the biomedical imaging and bioengineering (BI/B) workforce, including more opportunities and higher salaries in the private sector, not requiring or valuing postdoctoral training as much as other fields, and a higher number of graduate students with temporary visas. She noted that some ACD recommendations such as salary increases and supporting diverse perspectives will benefit postdoctoral scholars irrespective of their field of study. But she raised the question of whether all the recommendations fit the BI/B workforce or if additional ones are needed.</p>
<p>Dr. Erim noted NSF/NIH survey results showing a decline since 2020 in the number of postdoctoral appointees in bioengineering, despite a steady increase in the number of bioengineering doctoral students since 2018.</p>
<p>Councils experience and insights are needed in the new working group to:</p>
<ul>
<li>Evaluate the evidence on the perceived shortage of senior graduate students seeking U.S. postdoctoral scholar positions in BI/B.</li>
<li>Explore unique circumstances/drivers for the BI/B community</li>
<li>Recommend measures NIBIB should take in addition to or that differ from the ACD recommendations, and</li>
<li>Recommend a creative and impactful plan for restructuring the postdoctoral/research enterprise in BI/B including roles for universities and other government agencies.</li>
</ul>
<p>Dr. Erim closed by asking interested Council members to email her by September 24, 2024.</p>
<h3><strong>Discussion:</strong></h3>
<p>Council asked what is driving the concern with a few-year decline in postdoctoral scholars. Dr. Erim responded that the key concern that NIH was addressing was how a shortage of postdoctoral scholars would affect the biomedical enterprise as a whole in the future.</p>
<p>Council also noted that the decline might be tied to the career trajectory after a postdoctoral position ends and suggested considering creating a new research faculty track to follow a postdoctoral position.</p>
<p>Council also suggested clarifying whether the research pipeline should include industry or focus solely on academia and surveying senior graduate students about their interest in postdoctoral training.</p>
<p>Dr. Tromberg reiterated that the NIBIB community is somewhat different than the rest of NIH and that NIBIB wants to know how to best meet the needs of training programs in the future.</p>

Lediju Bell, Ph.D., John C. Malone Associate Professor, Departments of Electrical and Computer Engineering, Biomedical Engineering, Computer Science, and Oncology at Johns Hopkins University</h2>
<h3><strong>Background:</strong></h3>
<p>Dr. Bell began her talk with a tribute to the late Hector Lopez, Ph.D., a former NIBIB program director whom she met through the ultrasound community. Dr. Lopez played a role in Dr. Bells graduate research by providing NIBIB grants to her graduate advisor, which paved the way for her pioneering postdoctoral research. Since 2016, she has directed the Photoacoustic and ULtrasonic Systems Engineering (PULSE) Laboratory at Johns Hopkins University.</p>
<p>She described the PULSE labs cycle of innovation and its focus on designing beamformers and imaging probes. She defined beamformers as a mathematical-based, physics-based, signal-processing technique that can be applied interchangeably to photoacoustic and ultrasonic imaging because it uses much of the same hardware and software. Dr. Bell said the beamforming processing step is the first line of software defense against poor quality imaging and the focus of much of her research.</p>
<p>She explained that integrating ultrasound with light delivered through a laser beam produces photoacoustic imaging. A benefit of this type of imaging is that it can target any structure with higher optical absorption than its surroundings, which has the potential to provide new information for diagnostic imaging, surgery, and interventional guidance.</p>
<p>Dr. Bell described a problem with the conventional amplitude-based approach to beamformer design used in all ultrasound scanners. Highly random scattering (acoustic clutter) can occur, which leads to lower image quality and possible misinterpretation of images.</p>
<p>She developed a new coherence beamformer technique called short-lag spatial coherence (SLSC) to reduce acoustic clutter. She showed images of overweight and obese patients and dense breast tissue, factors which tend to lead to acoustic clutter, to demonstrate that image quality improved with her SLSC technique compared to the conventional approach.</p>
<p>Dr. Bell noted that conventional amplitude-based approaches can lead to inherent skin tone bias, as higher levels of melanin can result in acoustic clutter. She demonstrated that coherence-based beamforming can reduce acoustic clutter in people with higher melanin content (darker skin tones). She also showed a series of photoacoustic breast imaging simulations from the PULSE lab representing different skin tones and different wavelengths that indicated that skin is primarily responsible for the presence of acoustic clutter, regardless of skin tone or wavelength.</p>
<h3><strong>Surgical applications:</strong>&nbsp;</h3>
<p>Her lab designed a surgical guidance tool that transmits light from the tool tip onto a blood vessel, which generates sound that is received by an ultrasound probe. Her lab used simulations and cadaver experiments to identify three possible placements of ultrasound probes and then validated the photoimaging tool in different experiments. The results suggest that the tool could be useful in guiding minimally invasive neurosurgical procedures.</p>
<p>The PULSE lab has investigated the guidance tools broader surgical applications, including integrating it with the da Vinci robotic system to perform hysterectomies. The goal is to miniaturize the components of a photoacoustic imaging system, including a specialized light system, so it can be attached to any da Vinci tooltip. The researchers also created a sound to alert a surgeon when the tooltip is too close to the ureter to avoid injuries. Dr. Bell noted that NIBIB funded this research.</p>
<h3><strong>Minimally Invasive Procedures:</strong></h3>
<p>The image-guidance tool is also a promising approach for other minimally invasive procedures such as needle biopsies and catheter placements. Dr. Bell touched on various surgical applications and due to time constraints referred Council to her perspective in the <em>Journal of Applied Physics</em> for more information.</p>
<p>One of the applications is cardiac imaging. Starting with the core photoacoustic system, an ultrasound probe can be attached to a robotic arm and an optical fiber can be inserted into a cardiac catheter. This creates a new system that can autonomously stay centered on the catheter.</p>
<p>Dr. Bell also suggested that the photoacoustic imaging system could replace fluoroscopy for interventional guidance and that the systems components could be miniaturized to be unobtrusive. However, a tiny laser would produce a weaker signal, which could hinder tracking the catheter tip. That challenge could be overcome by using a coherence-based approach to beamforming.</p>
<p>The PULSE lab has also been investigating a coherence-based photoacoustic approach to flexible array technology, which would conform to different body shapes and sizes for wearable health applications.</p>
<h3><strong>Computations:</strong></h3>
<p>Dr. Bells lab has focused on replacing and speeding up the time-intensive cross-correlation step in the SLSC beamforming process. Using recorded data from samples, her research team has developed software (CohereNet) that uses deep neural networks to calculate the spatial coherence function. She demonstrated that CohereNet achieved a high image correlation when compared with the original time- intensive SLSC approach over the entire test set of images of breast masses and increased the processing speed.</p>
<p>Dr. Bell said that the same deep neural network approach to beamforming can be applied to photoacoustic imaging to reduce acoustic clutter and skin tone bias found in the traditional amplitude-based approach. Using machine learning, photoacoustic coherence functions were calculated to provide SLSC images for a diversity of skin tones, which further reduced acoustic clutter.</p>
<h3><strong>Key takeaways:</strong></h3>
<ul>
<li>Coherence-based techniques enable more equitable ultrasound and photoacoustic imaging.</li>
<li>Applications can range from diagnostic imaging to surgery and minimally invasive interventions, with patient-specific software and hardware.</li>
<li>Diversity drives innovation, including diversity of datasets. All types of patients should be included in the datasets for analysis representing diverse body shapes and weights, dense breast tissue, and darker skin tones related to optic-based technologies.</li>
<li>An interdisciplinary team in her lab also drives innovation.</li>
</ul>
<p>The PULSE lab has made its ultrasound and photoacoustic imaging resources publicly available.</p>
<p>Dr. Bell closed by saying that an NIBIB-funded supplement to her NIH Trailblazer Award enabled her to release software that can detect COVID-19.</p>
<h3><strong>Discussion:</strong></h3>
<p>Council asked about a particular focus or broader opportunity for technologies to determine the location of array elements in the context of beamforming. Dr. Bell responded that she sees many opportunities to apply flexible array technologies beyond photoacoustic imaging. This includes wearable health technologies and sound-speed estimation for ultrasound imaging, which her lab has been exploring recently.</p>
<p>Dr. Tromberg said there was an opportunity to investigate a frequency-dependent coherent response given the broadband nature of the photoacoustic signal. He asked Dr. Bell whether more mechanical properties including velocities and stress/strain could be extracted from the tissue. Dr. Bell responded that the theory her lab developed for photoacoustic imaging has led to a better understanding of how frequency influences the spatial coherence function. However, it would be interesting to dig deeper to see how that might impact blood flow or a velocity-based approach to imaging.</p>
<p>Dr. Bell added that combining coherence imaging with elastography might be an open area for investigation.</p>
