Patent ID: 7744279

Claim:
A radiation imaging system comprising: a radiation head including a radiation source and having an adjustable position and an adjustable angular orientation; a radiation image detection device comprising a photostimulable medium for recording an image according to radiation emitted from the radiation source; a single measurement sensor apparatus including a housing, the housing being adapted to be sequentially coupled first to the detection device and second to the radiation head, the measurement sensor apparatus continuously providing three-dimensional data for continuously determining changes in angular orientation of the measurement sensor apparatus while the measurement sensor apparatus (i) is coupled to the detection device, (ii) is being moved from a benchmark position in which the measurement sensor apparatus is coupled to the detection device to a position in which the measurement sensor apparatus is coupled to the radiation head, and (iii) is coupled to the radiation head; a processor responsive to the three-dimensional data from the measurement sensor apparatus to continuously determine change in three-dimensional angular orientation of the single measurement sensor apparatus, whereby the change in three-dimensional angular orientation for use by an operator of the radiation imaging system to manually adjust angular orientation of the radiation head in at least one direction to align the radiation head to the image detection device; and at least one indicator responsive to the processor to continuously indicate to the operator at least one angular orientation adjustment of the radiation head to be made manually by the operator in at least one direction to align the radiation head to the image detection device.
