Title: Innovations of Christopher E Cann
Introduction
Christopher E Cann is a notable inventor based in San Francisco, CA. He has made significant contributions to the field of imaging systems and bone health through his innovative patents. With a total of 3 patents, Cann's work has advanced the understanding and technology in medical imaging and fracture risk assessment.
Latest Patents
One of Cann's latest patents is an "Emission-transmission imaging system using single energy and dual energy." This invention enhances radionuclide emission imaging by correcting emission-transmission data for attenuation along calculated path lengths and through calculated basis material. The system utilizes X-ray transmission data to create an attenuation map, which is essential for reconstructing images based on emission data. Additionally, the radiation detection circuitry is designed with various operating modes to detect both x-ray and emission photons passing through the object. An iterative process is employed to reconstruct the radionuclide distribution using the projection data and the attenuation map, taking into account the physical characteristics of the object being imaged.
Another significant patent is the "Method for improved prediction of bone fracture risk using bone mineral." This non-invasive, in-vivo method analyzes bone for fracture risk by obtaining data through computed tomography or projection imaging. The data represents a measure of bone material characteristics, such as bone mineral density. By generating a finite element method (FEM) mesh from the distribution of these characteristics, Cann's method determines the load capability of the bone. The process involves mathematically 'compressing' the bone to assess stress, strain force, and force/area in relation to the bone material characteristics.
