3D Registration & Visualization

Title: Baseline Followup Comparison in ultrasonic videos

A traditional intra-patient baseline followup comparison is based upon 2D images in ultrasound, i.e. a radiologist acquires 2D images from some specific viewpoints in a baseline/reference exam and after some time when that patient visits the clinic again, the physician tries to replicate the exam by acquiring 2D images from approximately the same viewpoints. In this project we facilitate this process by acquiring videos instead of images and devising a way to register the two spaces.

Title: Validating diagnostic ultrasound using MRI

Current diagnosis related to musculoskeletal disorders based solely upon ultrasound is operator dependent. Physicians have identified planes of 2D ultrasound acquisition related to a particular disorder, and its necessary to place the ultrasound probe in a specific position and a specific angle in 3D space in order to have a consistent diagnosis. In this project, we try to reduce this inter-operator reliability of ultrasound using MRI as gold standard. The registration and fusion of 3D MR space with ultrasound video acquisition provides a virtual environment where a physician can place the probe at any desired position and angle of a joint and simultaneously see the corresponding plane of acquisition in ultrasound overlaid with the corresponding oblique plane of MR.

Title: Automatic scan planning in magnetic resonance imaging

Traditional MR acquisition requires a technician to manually identify the field of view. The aim of this work is to automate his process while reducing inter operator identification reliability and acquisition time simultaneously.
