Hi, I'm Stefan Dorsch. I'm a Postdoc at DKFZ&nbsp;&nbsp;

00:00:14.960 --> 00:00:19.840
and I'm working in MR-guided particle&nbsp;
therapy in the ARTEMIS Project.&nbsp;&nbsp;

00:00:26.320 --> 00:00:28.960
MR-guided radiotherapy in general&nbsp;&nbsp;

00:00:29.600 --> 00:00:36.880
aims to provide a superior anatomical information&nbsp;
about the patient. So it's even possible&nbsp;&nbsp;

00:00:36.880 --> 00:00:46.640
to track the tumor position during the treatment&nbsp;
itself. The tumor position may be varied by

00:00:48.880 --> 00:00:51.840
swallowing or breathing motion of the patient.&nbsp;&nbsp;

00:00:52.960 --> 00:01:01.840
Several devices for MR-guided radiotherapy with&nbsp;
photons already exist commercial solutions.&nbsp;&nbsp;

00:01:01.840 --> 00:01:05.600
However, for the particle&nbsp;
therapy no such devices exist.

00:01:07.680 --> 00:01:16.080
Several groups of DKFZ, the University Hospital&nbsp;
of Heidelberg and also the Heidelberg Ionbeam&nbsp;&nbsp;

00:01:16.080 --> 00:01:25.360
Facility (HIT) work on the development of a&nbsp;
prototype of such a device. My own research&nbsp;&nbsp;

00:01:25.360 --> 00:01:34.880
project aims at the investigation of the influence&nbsp;
of the beam on the MR image quality and also the&nbsp;&nbsp;

00:01:34.880 --> 00:01:42.880
development of new phantoms and quality assurance&nbsp;
processes for MR-guided particle therapy.

00:01:48.960 --> 00:01:55.120
What I really like is the vast&nbsp;
variety and the different tasks&nbsp;&nbsp;

00:01:56.320 --> 00:02:03.440
I have. So on the one hand I can&nbsp;
perform measurements, develop phantoms&nbsp;&nbsp;

00:02:03.440 --> 00:02:12.400
but as the measurements I took in the experiments&nbsp;
also have to be evaluated, I also spent some time&nbsp;&nbsp;

00:02:12.400 --> 00:02:20.320
on the computer. So in my point my point of view I&nbsp;
have a really nice balance between working on the&nbsp;&nbsp;

00:02:20.320 --> 00:02:25.840
computer, maybe also performing simulations,&nbsp;
but also making experiments in the field.

00:02:31.760 --> 00:02:39.520
Especially during the experiments, you can be&nbsp;
sure that at some point something unexpected will&nbsp;&nbsp;

00:02:39.520 --> 00:02:46.720
happen. So you really have to improvise and find&nbsp;
a spontaneous solution for that upcoming problem.&nbsp;&nbsp;

00:02:47.600 --> 00:02:55.920
And although our approach for the MR-guided&nbsp;
radiotherapy relies on two medical products&nbsp;&nbsp;

00:02:55.920 --> 00:03:02.720
meaning an already working MR scanner and also&nbsp;
the already working beamline at the HIT facility,&nbsp;&nbsp;

00:03:04.480 --> 00:03:10.560
even though these are medical&nbsp;
products, the interaction of both is&nbsp;&nbsp;

00:03:11.120 --> 00:03:19.200
not given to work at any time. So although each&nbsp;
product individually should work perfectly fine,&nbsp;&nbsp;

00:03:19.200 --> 00:03:31.840
in reality the integration of both covers&nbsp;
some really interesting problems and aspects.
