Method for recording image and evaluating functional three-dimensional computed tomography-recorded image during minimally invasive intervention in blood circuit of patient, involves associating each selected image point to contrast agents

摘要

The method involves recording and reconstructing two images (2, 3) in different x-ray spectrums in a blood circuit of a patient for differentiating two contrast agents e.g. tantalum and iodine. Image points are selected in the images such that image data exceed a preset threshold value ranging from 80 to 100 Hounsfield units. Each selected image point is associated to the contrast agents by using a two spectrum-discrimination process. Partial spaces associated to the contrast agents are defined by a discrimination line in a two-dimensional space spanned by the image data.
