Michael Ketcha is a PhD student at the I-STAR Lab in the Department of Biomedical Engineering at Johns Hopkins and is currently working on 3D-2D image registration in application to image-guided spine procedures with a specific goal in mind of automatically labeling vertbral target within a digital radiograph. In this project he has recently developed a method to overcome detrimental effects of anatomical deformation through a multi-stage registration framework. His past research includes shape analysis of cortical structures extracted from brain MR data, graph analysis of neural connectomes, and ultrasound pose recovery in image-guided procedures.

Qian Cao is a PhD student at the I-STAR Lab in the Department of Biomedical Engineering at Hopkins. He is currently working on the development of high resolution quantitative bone imaging capability in orthopedic CBCT, including multi-resolution iterative reconstruction, modelling and characterization of a CMOS-based CBCT imaging chain, and advanced image analysis algorithms for assessment of joint space morphology and bone microstructure. Before joining I-STAR, his previous research experience includes optical imaging and development of novel contrast agents in the extended near-infrared (exNIR) range.

Sarah Ouadah is a PhD student at the I-STAR Lab in the Department of Biomedical Engineering at Hopkins and is currently working on the development of task-based imaging using interventional C-arm systems. Her research includes development of a novel calibration technique using 3D to 2D image registration to extract the intrinsic and extrinsic parameters of the system with the purpose of allowing for atypical C-arm orbits and reducing artifact in the reconstructed images. Her previous research includes the development of realistic cardiac models from high resolution late gadolinium enhancement MR images, diffusion tensor MR images, and ECG data to aid surgeons in targeting locations for myocardial ablation for the treatment of tachycardia.
