Abstract
The invention relates to a method for the surface scanning of a patient, arranged on a patient's couch of a medical diagnostic device, with the following steps: Radiation of a light beam from a positioning light source onto the patient, detection of the light beam on the patient by an image sensor, arranged offset relative to the light beam, with the said light beam running from the positioning light source to the patient, movement of the patient relative to the positioning light source so that the light beam passes over the body of the patient, and determination of the surface of the patient from the detected light beam. A corresponding device is also claimed.
Claims17
A method for scanning a surface of a patient arranged on a patient's couch of a medical diagnostic device wherein the patient and the couch are moveable, comprising:
- radiating a light beam of a stationary positioning light source onto the patient;
- detecting the light beam on the patient by a stationary image sensor arranged offset relative to the light beam;
- moving the patient relative to the stationary positioning light source so that the light beam passes over a body of the patient;
- and
- determining a surface of the patient from the detected light beam,
- wherein the medical diagnostic device is a magnetic resonance system with the patient being moved into the system while arranged on the patient's couch, and
- wherein a position and presence of a high-frequency coil of the magnetic resonance system is checked based on the surface of the patient.
A device for scanning a surface of a patient being arranged on a patient's couch of a medical diagnostic device wherein the patient and the couch are moveable, comprising:
- a stationary positioning light source that beams a light beam onto the patient;
- a stationary image sensor arranged offset relative to the light beam that detects the light beam projected onto the patient;
- a device that moves the patient relative to the stationary positioning light source;
- and
- a computing unit that calculates a surface pattern of the patient from a position of the light beam detected by the image sensor,
- wherein the medical diagnostic device is a magnetic resonance system with the patient being moved into the system while arranged on the patient's couch, and
- wherein a position and presence of a high-frequency coil of the magnetic resonance system is checked based on the surface pattern of the patient.
