Problems solved by technology

The calcification score thus only gives how much coronary calcification is present in the coronary vessels of the heart, but cannot differentiate in how many of the four main coronary vessels of the heart the coronary calcification is measured
This information can be obtained using so-called coronary CT angiography, but coronary CT angiography itself is not used to determine the calcium score, since the patient must be dosed with a control agent and treated with a higher radiation dose

Embodiment Construction

[0044] exist figure 1 The X-ray computed tomography apparatus 1 shown in has a patient couch 2 for supporting a patient P to be examined. The X-ray computed tomography system 1 further comprises a gantry 4 with an X-ray tube-detector system mounted rotatably about a system axis 5 . The x-ray tube-detector system has an x-ray tube 6 and an x-ray detector unit 7 located opposite one another. In operation, X-ray radiation 8 is emitted from the X-ray tube 6 in the direction of the X-ray detector unit 7 and is detected by the X-ray detector unit 7 .

[0045] The patient couch 2 has a couch base 9 on which a patient support plate 10 provided for actually supporting the patient P is arranged. The patient support plate 10 is adjustable relative to the couch seat 9 , so that the patient support plate 10 and the patient P can be introduced into the opening 3 of the gantry 4 in order to record a 2D X-ray projection of the patient P, for example in a helical scan. The computational pro...

Abstract

The present invention relates to a method and a device for identifying and assigning coronary calcification to at least one coronary vessel of a heart (H) in a patient (P), wherein coronary calcification is identified on the basis of a 3D image data record of the heart (H) in the patient (P), which data record was generated by an imaging instrument without contrast agent being administered; at least one 3D model (30) of the profile of the coronary vessels (31 to 34) in a human is provided; and wherein the identified coronary calcification in the patient (P) is assigned to at least one coronary vessel (31 to 34) of the at least one 3D model (30) of the profile of the coronary vessels (31 to 34) in a human. Moreover, the invention relates to a computer program product, having a computer program (13) that is stored on a medium that can be read by a computational unit (12), for carrying out the method for identifying and assigning coronary calcification when the computer program (13) is loaded into the computational unit (12).

Description

technical field [0001] The present invention relates to methods and apparatus for identifying and correlating coronary calcifications with cardiac coronary vessels of a patient's heart. Furthermore, the invention relates to a computer program product with a computer program for carrying out the method. Background technique [0002] Heart and cardiovascular diseases are widely prevalent in Western industrialized countries. Currently, for example, one quarter of German citizens suffer from high blood pressure, and approximately 400,000 German citizens suffer from myocardial infarction or stroke every year, the main cause of which is arteriosclerosis. Arteriosclerosis is understood as a disease of the arteries in which deposits of calcifications etc. form on the inner walls of the arteries. If calcifications, for example, close off the coronary vessels of the heart, myocardial infarction can result. [0003] To estimate a patient's risk of suffering a myocardial infarction, ...
