Use of tissue composition and anthropomorphic measures in a method for the detection and quantification of arterial calcification in an organ is described for disease risk prediction and stratification. A radiographic image of an organ is transformed quantitatively to a tissue composition map indicating a total amount of organ tissue; a calcification map is generated indicating position in the tissue composition map of calcified tissue; calcification free tissue composition map is generated from the tissue composition map using the position of calcified tissue in the calcification map; a vessel map of the position of vessels in the tissue composition map is generated; and the vessel map is combined with the calcification map to generate a map of vessel calcification indicating the position of calcified vessels in the tissue composition map. Scores are based on arterial calcification in a breast which indicates disease in the breast and other organs.

Method for detection and quantification of arterial calcification

The present invention relates to a system and apparatus comprising automated analysis and feedback on soft tissue imaging quality, including analysis and feedback in real time and in conformance with key parameters and metrics which affect the quality of an image. The system is arranged to implement a method wherein method for providing a qualitative and/or quantitative assessment of an image including several steps. The steps include using an imaging apparatus to obtain at least one soft tissue image of a patient and at least one test object image; deriving a soft tissue image parameter and statistical data from image data from the soft tissue image. The system and method are characterised by employing a metric for the assessment in comparison to the parameter and statistical data, wherein the metric is obtained from the soft tissue image data, data obtained from the at least one test object image, and data from the imaging apparatus.
