Patient support apparatus for a medical imaging apparatus and a medical imaging apparatus having the patient support apparatus

摘要

A patient support apparatus for a medical imaging apparatus, such as a magnetic resonance apparatus, is proposed. The patient support apparatus has a couch, a lifting unit for vertical movement of the couch, a travel unit, and at least one sensor unit to detect at least one weight variable for determining the weight of a patient. The at least one sensor unit has at least one sensor element, which is disposed on the lifting unit and/or on the travel unit.

主权项

1. A patient support apparatus for a medical imaging apparatus, comprising:
a couch for laying a patient; a lifting unit for vertically moving the couch; a travel unit; a sensor unit comprising a sensor element for detecting a weight variable for determining a weight of the patient; and a force transmission element that is disposed on one end of the lifting unit facing the couch, wherein the sensor element is disposed on the lifting unit and/or on the travel unit, and wherein the sensor unit further comprises a reference sensor element for detecting a reference variable generated within the sensor element to eliminate an interference signal from the weight variable, wherein the interference signal is generated due to magnetic field and/or gradient field applied in the medical imaging apparatus within the sensor element, and wherein the reference sensor element is configured to detect the interference signal before the sensor element detecting the weight variable of the patient when the medical imaging apparatus has been started up.
