Optimization of high-performance 3D/4D surface scanning technology for patient monitoring in radiotherapy environment
Patient movement monitoring takes advantage of high-precision, high-resolution 3D surface scanning technology. DLP micro- mirror technology was adopted to implement state-of-the-art solutions in terms of accuracy, speed, and data density. For ultra-high-speed 3D/4D scanning, it would be ideal to use the 10-20 kHz switching rate of DLP pattern generator combined with an equivalent area imaging device. New sensor concepts are under development to overcome the speed barrier of conventional machine vision cameras and a new level of electronics integration is promising to solve the task.
Within this project, the Fellow has conducted a systematic study of the performance of that new generation of 3D/4D sensors and contributed to the optimization of the system used over an extended time with radiation exposure. In general, this project is focused on optimizing the long-term availability and reliability of new 3D/4D scanning sensors made by ViALUX.
The theoretical background of radiation interaction with electronic devices has been systematically studied and experimental work performed benefiting from the extensive OMA partner network for gaining real-world data and application knowledge.
