System for Adaptively Processing Medical Image Data

摘要

A system locally allocates relatively higher and lower spatial resolution areas of a medical X-ray image in response to image spatial resolution requirements of individual sections of a partitioned image. A system processes image data by adaptively varying pixel resolution within a 2D (two Dimensional) X-ray medical image. The system includes an imaging detector comprising a matrix array of detection picture elements having a detector pixel resolution for detecting X-rays passed through patient anatomy. An image data processor determines a first area within a 2D image to be allocated a first pixel resolution and a second area within the 2D image to be allocated a second pixel resolution lower than the first resolution. A combinational processor combines image data of multiple adjacent detection picture elements to provide an individual pixel of the second pixel resolution. A user interface generates data representing a 2D X-ray medical image including the first area having the first pixel resolution and the second area having the second pixel resolution lower than the first resolution.
