Abstract
An x-ray diagnostics installation for peripheral angiography examinations includes a control unit having an arithmetic unit that, on the basis of subject-related data supplied thereto, effects a pre-setting of the electrical parameters of the installation required for every exposure, plus the step length and the number of steps of the relative adjustment of the exposure unit and the patient support relative to one another, as well as the required diaphragm setting. By virtue of the pre-setting, stress on the patient is reduced, and since the overall time per examination is also reduced, patient throughput can be increased.
Claims12
An x-ray diagnostics installation for peripheral angiography comprising:
- an x-ray exposure means for generating an x-ray beam and for detecting said x-ray beam after passage through a patient to obtain an x-ray exposure of said subject, said x-ray exposure unit including diaphragm means for selectively gating said x-ray beam;
- a support unit for receiving a patient to be examined using said x-ray exposure means, said support unit and said x-ray exposure means being relatively movable through a plurality of steps each having a step length with an exposure of said patient being obtained by said x-ray exposure means at each of said steps to obtain a plurality of successive exposures;
- and
- control means connected to said x-ray exposure means and to said support unit for controlling operation of said x-ray exposure means and said support unit, including controlling said diaphragm means, said control means including arithmetic means for calculating values for pre-setting one or more of said plurality of successive exposures, said step length and said plurality of steps matched to said patient based on subject-related data including the size, weight and physique of said patient.
