Diagnostic Imaging

Prototype cone-beam CT imaging systems are under development for musculoskeletal (MSK) radiology as well as imaging of traumatic brain injuary (TBI) and stroke. Such systems open new possibilities for point of care imaging. In each case, the I-STAR Lab is … Continue reading

3D Image Reconstruction

A general penalized likelihood (PL) framework has been developed for model-based 3D image reconstruction in cone-beam CT, providing a valuable basis for novel reconstruction techniques such as KCR, PIR-PLE, and MCR and providing dramatic improvement in image quality compared to … Continue reading

Image Registration

Deformable image registration is essential to accurately aligning information in the reference frame of the most up-to-date point in an interventional procedure. Research in the I-STAR Lab has developed a framework for fast deformable registration that adapts methods such as … Continue reading

Imaging Physics

Mathematical models of image quality can fuel the development of new imaging systems, optimize system design, identify methods to improve image quality and reducing dose, and accelerate the translation of new technologies to first clinical application. Among the most exciting … Continue reading

Image-Guided Interventions

The development of high-performance intraoperative 3D imaging promises to overcome the limitations of conventional image-guided surgery with up-to-date images during surgery that accurately present changes associated with patient setup, tissue deformation, and target excision. A prototype mobile C-arm for high-quality … Continue reading
