4D Image-Guidance

​Comprehensive 4D image database

We are currently acquiring an extensive 4D image data set of patients with indications in the thorax and abdomen:

Using this data set we aim

1. to acquire detailed insights into inter- and intra-fractional variations in patient geometry,
2. to establish and validate safe and efficient proton therapy treatment approaches for moving targets and
3. to establish and validate adaptive treatment regimes.

Treatment monitoring based on 4DCBCT

Development and application of methods to transfer motion information from daily 4D-CBCTs to the 3D or 4D planning CTs, in order to obtain a virtual 4DCT representing the “motion of the day”.
