Novel Imaging Systems

The development of new imaging systems is at the heart of I-STAR research, with applications ranging from diagnostic radiology to image-guided interventions. Such work includes the modeling of image quality, design of system geometry and components, construction of prototypes, measurement of imaging performance, and translation to first clinical studies. Drawing from mathematical models of image quality and physical experimentation on laboratory imaging bench, example systems include: (1) a mobile cone-beam CT system for imaging patients with traumatic brain injury at the point-of-care; (2) a compact CBCT scanner for imaging of the weight-bearing foot, ankle, and knee as well as upper extremities for MSK radiology and orthopaedics; (3) mobile C-arms for high-quality intraoperative cone-beam in surgery; (4) novel configurations of ultrasound imaging, endoscopy, and surgical navigation systems; (5) advanced CT systems based on photon-counting detectors and low-noise, high-resolution CMOS detectors; and (6) cone-beam CT on a linear accelerator for guidance of radiation therapy.
