EchoVQA: Enabling Conversational Assistance for Point-of-Care Cardiac Ultrasound
Filippos Bellos, Yutong Li, Jessie N Dong +6
Point-of-care transthoracic echocardiography (TTE) enables cardiac assessment in virtually any clinical setting, yet its diagnostic utility remains constrained by the expertise req…
Follow Your Heart: Landmark-Guided Transducer Pose Scoring for Point-of-Care Echocardiography
Zaiyang Guo, Jessie N. Dong, Filippos Bellos +8
Point-of-care transthoracic echocardiography (TTE) makes it possible to assess a patient's cardiac function in almost any setting. A critical step in the TTE exam is acquisition of…
Biomechanically Informed Image Registration for Patient-Specific Aortic Valve Strain Analysis
Mohsen Nakhaei, Alison Pouch, Silvani Amin +8
Aortic valve (AV) biomechanics play a critical role in maintaining normal cardiac function. Pathological variations, particularly in bicuspid aortic valves, alter leaflet loading,…
Increasing LLM response trustworthiness using voting ensembles
Aparna Nair-Kanneganti, Trevor J. Chan, Shir Goldfinger +3
Despite huge advances, LLMs still lack convenient and reliable methods to quantify the uncertainty in their responses, making them difficult to trust in high-stakes applications. O…
Towards Patient-Specific Surgical Planning for Bicuspid Aortic Valve Repair: Fully Automated Segmentation of the Aortic Valve in 4D CT
Zaiyang Guo, Ningjun J Dong, Harold Litt +10
The bicuspid aortic valve (BAV) is the most prevalent congenital heart defect and may require surgery for complications such as stenosis, regurgitation, and aortopathy. BAV repair…
