Method for determining temperature in volume area of body of patient in medical area, involves calibrating ultrasonic device by MRI sensor for determining temperature in volume area, where device and sensor are monitored in parallel

摘要

The method involves calibrating an ultrasonic device (12) by a MRI sensor for determining temperature in a volume area (8) of a body of a patient (4). The temperature, spatial temperature distribution and/or time course is monitored in the volume area, and a warning signal is provided when predetermined safety criteria are fulfilled. The ultrasonic device and the imaging sensor are monitored in parallel, where measuring data of the ultrasonic device and the imaging sensor are checked with one another. A mapping function is determined based on the data. An independent claim is also included for a device with a thermal treatment apparatus.
