MEDICAL IMAGING APPARATUS HAVING MULTIPLE SUBSYSTEMS, AND OPERATING METHOD THEREFOR

摘要

In a method for operating a medical imaging examination apparatus having multiple subsystems controlled by a control computer in a scan sequence, a control protocol for the scan is provided to the control computer, which determines sequence control data for the control protocol that define different functional subsequences of the scan, with different effective volumes assigned to each functional subsequence. Current ambient conditions of the apparatus are determined that are decisive for the determined relevant sequence control data and associated effective volumes. Control signals for the scan are determined from the sequence control data, the effective volumes and the current ambient conditions determined that optimize the functional subsequences of the scan.

1. A method for operating a medical imaging examination apparatus comprising a plurality of apparatus subsystems, comprising:
providing a control protocol to control computer that is assigned to a scan sequence in which said control computer will control the plurality of apparatus subsystems in coordination to conduct the scan sequence to acquire medical imaging data from an examination subject; in said control computer, determining sequence control data for said control protocol that define different functional sub-sequences of said scan sequence to be performed respectively by said apparatus subsystems; in said control computer, assigning respectively different effective volumes of the examination subject to the respective functional sub-sequences; in said control computer, determining current ambient conditions of said medical imaging examination apparatus that affect said sequence control data and said effective volumes; in said control computer, calculating and storing control signals for said scan sequence dependent on said determined sequence control data, the determined effective volumes, and the determined current ambient conditions, by executing an algorithm in said control computer that optimizes the functional sub-sequences locally in the examination subject at least with regard to a sub-region of the respective effective volumes; and making the stored control signal available at an output of the control computer as an electronic signal in a form for operating the medical imaging examination apparatus according to the stored control signals.
