POSITION SENSING APPARATUS FOR RADIATION IMAGING SYSTEM

摘要

A radiation imaging system includes a radiation head with a radiation source and an adjustable angular orientation. A radiation image detection device has a photostimulable medium that records an image according to radiation emitted from the radiation source. An measurement sensor apparatus, preferably inertial, is coupled to the photostimulable medium to provide three- dimensional data for determining the orientation of the photostimulable medium. There is at least one indicator responsive to the orientation data from the measurement sensor apparatus for indicating an orientation adjustment of the radiation source is needed in at least one direction.
