Title: Method and apparatus for measuring the accuracy of models generated by a patient monitoring system
Inventor: IVAN DANIEL MEIR
IPC: G06T7/70
Filed: 2017-08-08
Abstract: A method of identifying portions of a model of a surface (204, fig 6) of a patient which can be used to identify to position of a patient (20, fig 1) is provided. A pre-existing model of the surface (204) of a patient is utilised to generate (102) simulated images of the projection of patterns of light onto the surface (204) of the patient (20). The simulated images are then processed (104) to generate a further model of the surface. Any differences between the model generated by processing the simulated images and the original model surface identifies portions of the surface (204) which cannot be reliably modelled and hence portions of a surface (204) which should not be used to monitor the positioning of a patient (20). The invention has particular application for identifying the reliability and accuracy of generated models of the surface (204) of a patient used for monitoring and positioning a patient (20) undergoing radiotherapy.
