Title:
Practical machine learning approaches for medical image registration

Abstract:
Image registration, the process of establishing spatial correspondences between images, is a key task in medical image computing. For example, to facilitate analyses in a common atlas spatial coordinate system or to track changes over time in radiation treatment planning. Image registration approaches have been extensively developed over the previous decades with a shift to approaches based on deep learning over the last decade. However, while modern deep learning registration approaches allow for highly accurate and fast registrations many existing approaches are task-specific. Hence, these approaches require extensive retraining or fine tuning for a new registration task. This talk will provide an overview of approaches to obtain deep registration networks that generalize across image types and registration tasks. It will also discuss some recent work on building deep registration models with desirable equivariance properties as a further step towards registration models that work well in practice and that behave somewhat more predictably.

Title:
From Data to Verdict: How the US Litigation System Advances, Tests, and Distorts Neuroimaging Science
Abstract:
Advanced neuroimaging is increasingly entering courtrooms, creating a parallel translational pathway that complements traditional academic publication and the regulatory approval process. Whereas scientific acceptance emphasizes peer review and replication, and regulatory clearance through the U.S. The Food and Drug Administration focuses on population-level safety and efficacy, legal admissibility centers on methodological reliability and individualized application. This talk examines how litigation functions as a real-world validation ecosystem for neuroimaging data analysis. On the translational side, legal cases fund comprehensive evaluations that are often independent of clinical reimbursement constraints. This exposes advanced analytic tools to patients who might not otherwise access them and subjects them to varying levels of transparency through adversarial scrutiny. The legal process also introduces structured bias, strategic challenges, and the risk of misinterpretation under high-stakes conditions. By analyzing how evidence operates across low-value personal injury claims to high-value medical malpractice litigation, this presentation illustrates how legal deployment can refine documentation standards, improve reproducibility, and expose gaps and misuse of regulatory cleared processes. Ultimately, engaging thoughtfully with litigation environments can advance the development of robust, interpretable, and patient-centered neuroimaging algorithms that might otherwise take decades to reach the general population, while also acknowledging the structural risks inherent in adversarial systems.

Title:
How to Tickle the Brain Without Touching It

Abstract:
Focused ultrasound (FUS) offers a rare combination in neuroscience: the ability to deliver millimeter-scale, noninvasive energy to deep brain structures with exquisite spatial precision. When paired with MRI, FUS becomes a fully image-guided neuromodulation platform capable of accurate targeting, real‑time monitoring, and whole-brain functional readout through fMRI. This talk will highlight collaborative efforts across �Ӱ�ԭ�� to engineer and validate this platform in preclinical models and move it along the translational pipeline to humans.

Recent advances include optical tracking to minimize targeting error, multi-element FUS arrays enabling rapid beam steering and multi-site stimulation, and MR acoustic radiation force imaging (MR‑ARFI) for robust visualization of the acoustic focus. These tools have enabled reliable modulation of both cortical and deep nuclei and have revealed network-level mechanisms of action. Functional studies show that low-intensity FUS can selectively suppress thalamic responses to tactile and nociceptive input, disrupt thalamocortical information flow, and reconfigure distributed brain networks. Comprehensive safety assessments combining MR thermometry, acoustic pressure simulations, and histology demonstrate safe operating windows suitable for translation.

Together, these engineering and preclinical advances are driving MRI‑guided FUS toward clinical neuromodulation studies, including early applications in essential tremor and post-stroke pain. By integrating imaging, modeling, and therapeutic ultrasound, this work lays the groundwork for precise, noninvasive brain stimulation approaches that extend the reach of both neuroscience and medicine.

Title:
Guiding with touch: Objective assessment and haptic cueing to improve surgical performance on virtual and robotic platforms

Abstract:
Recent advances in simulation and robotic surgery have changed the way surgeons are trained in terms of their ability to gain experience without risk to patients. However, the feedback surgical trainees receive during training is still delayed, subjective, and qualitative, which does not provide the maximum support for rapid acquisition of motor skill. In this talk, I will describe our research on identifying objective and quantitative metrics that capture surgical skill in the endovascular domain. Specifically, we have shown that low-level properties of movements (e.g., smoothness) made in the performance of several motor tasks—including surgery in both virtual and robotic environments—are highly correlated with high-level performance outcomes, such as expert evaluations in surgical environments. I will also describe our progress in transforming these performance metrics to haptic representations that are provided in real-time to a trainee. We have shown that the provision of real-time haptic feedback during training of complex motor tasks can alter trainee strategies and learning curves. We hypothesize that we can enhance surgical performance and training by providing performance feedback based on these same motion-based metrics that quantify movement quality and strategies rather than task outcomes. This approach allows trainees to receive feedback that is immediate and quantitative, which should amplify human capabilities and result in improved performance in difficult-to-train motor domains such as surgery.

Title:
Neuroimage Analysis in Autism: from Model-Based Estimation to Data-driven Learning

Abstract:
Functional magnetic resonance imaging (fMRI) has been shown to be helpful for the study of autism spectrum disorders (ASD). This talk will describe the evolution of efforts in this area within our group that carry promise for producing objective biomarkers for ASD, as well as predicting patient response to a behavioral therapy known as Pivotal Response Treatment (PRT), using task-based fMRI. Such biomarkers would provide an important step for better understanding the underlying pathophysiology of ASD that could help with objective and personalized diagnosis, provide new targets for development of new treatments, and provide a way to monitor patient progress. Initially a robust, group-wise unified Bayesian framework to detect both hyper and hypo-active communities from connectivity maps will be described. Next, more recent work will be presented that has focused on deriving ASD biomarkers from individual subject time-series data, based on the classification of individual subjects (into ASD or typical control) and identifying spatially-specific key regions using graph convolutional neural networks and ablation analysis of regions. In addition, a strategy based on recurrent neural networks (using long-short-term memories or LSTMs) will be presented that predicts patient response to PRT behavioral therapy from baseline imaging while incorporating subject-specific phenotypic information for network initialization. Finally, initial efforts on the use of a spatiotemporal transformer strategy for classification and early work on the use of effective connectivity based on whole brain dynamic causal modeling as an alternative or an adjunct to functional connectivity for classification and biomarker analysis will be discussed.
