Respiratory Motion GatingRespiratory Motion is an emerging issue; clinicians have to care about
respiratory movement in various applications not only in the near future but
also today. There are various fields of applications within medicine where
respiratory motion has to be accounted, e.g. 4-D CT, 4-D MRI, PET, SPECT,
Radiotherapy. Nowadays, imaging devices are sufficient enough in spatial resolution to
acquire high quality images, but the temporal resolution, especially in
applications, where moving targets are observed causes still problems.
Basically there are two sources causing motion within the body:
The motion caused due to respiration is accounted within this project. This project investigates the ability of time-of-flight sensors to enable
new ways of a non contact multidimensional measurement of respiratory
motion. Using this new technology, no additional markers or hardware is
required to be applied to the patient. It is possible to acquire an n-D
respiratory signal of the patient. This signal can be used to reconstruct
4-D CT, 4-D MRI, PET, SPECT. Furthermore it can be used for gated
radiotherapy applications. | Project manager: Prof. Dr.-Ing. Joachim Hornegger
