摘要

Method and device for computed tomography examination of dynamic CT in one patient and means of data.The present invention relates to a method for a device for computed tomography (11) and a device (11) for computed tomography examination of dynamic CT in a patient (P), which has a frame (12) with a stationary part (13) and a part (14) that po. To be rotated around a geometric axis system (15).In the rotating part (14) of an X-ray radiation source (16) and a radiation detector X (17) are devices in opposition to one another, a diaphragm (30) which is allocated to that source of X-ray radiation (16), which is part of the diaphragm (31).32) that can be moved in the direction of the axis geometric system (15) for limiting a beam of X-ray radiation (18) originating from the source of radiation of X-rays (16) in the direction of the geometric axis system (15), and a support plate of the patient (21) that may be mo Life in the direction of the axis geometric system (15).With the method, the support plate of the patient (21) is moved in the direction of the geometric axis system (15) between a first and a second position of the edge (e1pl, e2pi) of the support plate of the patient (21), and, at the same time, elements of the diaphragm (31).32) of the diaphragm (30) are moved in the direction of the geometric axis system (15) between a first and a second position of the edge (e1diaphragm, e2diaphragm) of the elements of the diaphragm (31,32). The invention also relates to a means of data (25), which has a computer program (26) that implements the method.
