Method and Apparatus for Reconstruction of Medical Image Data by Means of Filtered Backprojection

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a system and method for reconstructing medical images by using filtered backprojection enhanced with a wavelet transformation. The process involves applying a special filter to projection data collected from a detection device, which helps to improve the quality of the reconstructed images before the final backprojection step.

Use CasesContent extracted from patent full text and abstract with AI.

• Improved CT (computed tomography) and MRI (magnetic resonance imaging) reconstruction in hospitals
• Medical imaging for cancer screening and diagnosis
• Enhanced 3D reconstruction in dental and orthopedic imaging
• Accelerated processing of large medical imaging datasets for telemedicine

BenefitsContent extracted from patent full text and abstract with AI.

• Produces clearer and more accurate medical images for diagnosis
• Can reduce noise and artifacts in reconstructed images
• Enables faster and more reliable image processing
• Potentially reduces the amount of radiation needed per scan by improving reconstruction quality
• May increase diagnostic confidence for physicians

Patent Abstract

A system and method are provided for the reconstruction of medical image data using filtered backprojection with the use of a wavelet transformation. A filter function is applied to at least one part of an object using projection data captured with a detection device prior to backprojection.
