The ultrasound research platform "DiPhAS-MRT" was devel-

oped especially for use for simultaneous imaging on the MR

tomograph. With this system it is possible to combine the

advantages of MR imaging (high tissue contrast) with those of

ultrasound imaging (real-time capability). The DiPhAS-MRT is

used, for example, for the ultrasound-based motion detection

of internal organs during MRT imaging. For this application

special adhesive ultrasound transducers were developed that

can register three-dimensional information on organ move-

ment on up to four ultrasound levels. This ultrasound data

taken in parallel operation and the motion vectors calculated

from them are then used for compensation of movement arte-

facts in the MRT scans.

The challenge in the realization of this system consisted in the

adaptation of the beam former and the ultrasound transducer

to the high magnetic fi elds of the tomograph and in the mini-

mization of the electromagnetic interference of the ultrasound

system in order not to infl uence the MR imaging.

Alongside the application on the 1.5-T and 3-T magnetic reso-

nance tomographs, the system and the methods were also

tested for the real-time motion detection on PET-CT scanners,

radiotherapy systems and in combination with heavy ion ther-

apy systems.

This work was supported by the Fraunhofer Internal Programs

under Grant No. MAVO 823 287.
