Image processing system for use with a patient positioning device

摘要

An image processing system ( 1 - 5 ) is provided which obtains images of a patient ( 8 ) from multiple view points and which then generates positioning instructions for a mechanical couch ( 7 ) to vary the position of a patient. A number of techniques are disclosed in order to calibrate the image processing system so as to enable the image processing system to identify the iso centre of radiation beams generated by a treatment apparatus ( 6 ). Techniques for processing generated 3 dimensional models to monitor a patient's breathing are also disclosed.
