MRI APPARATUS WITH LOW-FREQUENCY CABLE INTEGRATED INTO THE PATIENT CARRIER

摘要

In a medical MRI apparatus, it is often desirable to have devices 62, 64 for communicating with or monitoring the patient 58 in the imaging volume 29 of the apparatus. Such devices need DC power or low-frequency connections with an area 70 outside the imaging volume. A device cable that does not interfere with the MRI magnetic fields is known per se. The invention proposes to fix the device cable in a groove 76 in the patient carrier 60 in such a manner that its strip-shaped conductors 78, 80 extend parallel to the field lines of the stationary field B of the apparatus. In this way, it is also possible to clip device carriers 72, 74 to the groove, thus supplying the devices with DC power or establishing an audio connection through the device cable in the groove.
