Abstract
Description
technical field
[0001] The invention is in the field of radiology imaging and analysis, and particularly describes analysis and analysis techniques in a networked environment, and also describes devices including calibration phantoms and methods of using these devices. Background technique
[0002] X-rays and other radiographic analyzes are important diagnostic tools. Transmission of X-ray images over a local remote network is more common practice. However, the current technology cannot accurately determine the X-ray information (such as anatomical structure density) in the X-ray images transmitted in the network environment.
[0003] The article also describes the calibration references (also known as calibration models) used in imaging techniques. See US Patent No. 5,493,601 and US Patent No. 5,235,628. U.S. Patent No. 5,335,260 discloses a calibration phantom representing human tissue containing varying concentrations of calcium as a reference for quantifying calcium, ...
