X-ray Image-based Bone Fragment Tracking

Invention novelty: This invention is a surgical navigation system that assists in acetabular realignment during periacetabular osteotomies (PAO) in hip dysplasia patients. Value Proposition:Patients with hip dysplasia have a shallow, dish-shaped acetabulum, compared to a normal cup-shape. Untreated hip dysplasia can lead to a breakdown in joint cartilage,...

Spatial-spectral filters for multi-material decomposition in computed tomography

Unmet NeedMore than 80 million CT scans are conducted every year in the US to detect and monitor a variety of diseases such as cancer, heart disease, and bone disorders. CT scans make use of computer-processed combinations of X-ray measurements to produce images of the patient’s body. The methods for this processing are constantly changing due to advancements...

Glancing Angle Interferometer Tomosynthesis System (GAI-TS) for High Energy, Fast and Low Dose X-ray Phase-contrast Imaging

Unmet NeedCurrent clinical imaging methods include conventional X-ray computed tomography (CT), and magnetic resonance imaging (MRI). Conventional X-ray CT, also known as attenuation-based X-ray CT, has excellent spatial resolution but poor soft tissue contrast, so it is not suited for imaging internal organs. Meanwhile, MRI has good soft tissue contrast...

A radiation treatment couch with integrated helical CT for on-line image guidance

Unmet NeedImage-guided radiation therapy (IGRT) denotes the use of imaging, usually CT scans and X rays, to precisely help target the cancer tissue with radiation therapy. This is specifically done through a flat-panel detector in cone beam computed tomography (CBCT) for IGRT. Flat panel CBCT imaging quality is degraded by several issues: 1) less than...

Multi-Motion Compensation for Computed Tomography

Unmet NeedDuring computed tomography (CT) or cone-beam CT, scans can be affected due to patient motion that causes significant artifacts that diminish image quality. This is functionally the case because of slow image acquisition speed, causing artifacts in the image due to patient’s difficulty in following commands and remaining still. Furthermore,...

X-ray Phase-contrast Scanning Radiography Systems Using Multi-view Glancing Angle Interferometers

Unmet NeedMedical imaging is an essential tool for modern medical practice. Imaging techniques such as MRI, X-ray, and ultrasound are used for disease prevention, early diagnosis and treatment of many medical conditions. Each of these methods has advantages and disadvantages. MRI and ultrasound provide good soft tissue contrast while X-ray does not; ...

Geometric Calibration for Cone Beam CT using Line Fiducials

Unmet NeedTraditional BB-based geometric calibration methods for cone-beam CT (CBCT) rely significantly on foreknowledge of the scan trajectory shape. This is a hindrance to the implementation of variable trajectory CBCT systems, normally requiring a dedicated calibration phantom or algorithm for every scan orbit of interest. A more flexible method...
