Backprojection Method for 3D Image Reconstruction

Unmet NeedComputed tomography (CT) use has dramatically increased over the past 20 years such that around 31% of primary care patients undergo CT scans every year. All CT scans employ “back-projection” as the basic computational method to relate 2D detector signal values into a 3D re-construction. However, image reconstruction sometimes leads to noise...

Fast and Automatic Periacetabular Osteotomy Fragment Pose Estimation Using Intraoperatively Implanted Fiducials and Single-View Fluoroscopy

Unmet NeedDevelopmental dysplasia of the hip (DDH) is the most common developmental hip deformity in children, and the most common single cause of osteoarthritis of the hip in young and older adults. This condition occurs when there is insufficient coverage of the femoral head by an excessively shallow acetabulum (hip socket). Periacetabular osteotomy...

A comprehensive post-processing toolbox for magnetic resonance based peripheral vascular imaging

Peripheral artery disease (PAD) is an important public health concern particularly among the elderly. Although measures such as ankle-brachial index and segmental pressures have been used to characterize disease severity, new magnetic resonance based imaging techniques allow us to assess subclinical vascular function and morphology. Here, we describe...

Improved Fitting Calculation For Diffusion Tensor Imaging

Diffusion tensor imaging is a new MRI modality that is becoming an important technique to assess various types of brain diseases. However, this technique has one weakness; its extreme sensitivity to patient motions. The image is often corrupted by patient motions as small as cardiac pulsation of the brain. Even though this problem is ameliorated by...
