MAGNETIC RESONANCE APPARATUS AND METHOD FOR OPERATION THEREOF

摘要

In a method to operate a magnetic resonance device to acquire magnetic resonance data of an acquisition region of a patient that is moving due to respiration, a breath hold command is automatically given to the patient by an output unit of the magnetic resonance apparatus before acquisition of the magnetic resonance data, and the acquisition of the magnetic resonance data is begun automatically given a trigger signal determined from measurement data of the patient, the trigger signal indicating that breath is being held.

主权项

1. A method to operate a magnetic resonance apparatus comprising;
from a computerized control unit, automatically providing a breath hold command to a respirating patient situated in a magnetic resonance apparatus via a command output unit of the magnetic resonance apparatus, before operating said magnetic resonance apparatus to acquire magnetic resonance data from the patient; acquiring measurement data from the examination subject representing physiological movement of the patient due to the respiration and automatically analyzing said measurement data in said control unit to identify a time at which the patient, after said breath hold command, is physiologically implementing a breath hold; and at said time, automatically emitting a trigger signal from said control unit that initiates the acquisition of magnetic resonance data from the patient.
