INSTANTANEOUS VISUALIZATION OF CONTRAST AGENT CONCENTRATION IN IMAGING APPLICATIONS |
摘要 |
A system (600) is proposed for imaging a body part including a tissue, the body part being perfused with a contrast agent. The system includes means (603- 606) for providing a sequence of original images offering a digital representation over time of the body-part, each original image including a plurality of original values each one indicative of a response to an interrogation signal of a corresponding location of the body-part possibly including the contrast agent with a contribution of the tissue substantially reduced. The system further includes: means (609-651) for generating an overlaid image for each one of a set of selected original images, for each one of a set of selected locations the overlaid image including an overlaid value consisting of: a) a linearized value derived from the corresponding original value to be substantially proportional to a concentration of the contrast agent in the selected location when the linearized value reaches a predefined threshold, or otherwise b) a compressed value depending non-linearly on the corresponding response to the interrogation signal; and means (654-660) for displaying the overlaid images in succession.
