COMPACT MEDICAL IMAGER

摘要

The specification discloses a compact medical imaging device, comprising a collimator for collimating radiation emanating from a radioispharmaceutical present in a subject being examined, the collimator having an input side, an output side, a longitudinal collimation axis, and an array of collimating channels extending between the intput and output sides and parallel to the collimation axis. A radiation collection module has an input side coupled to the collimator for intercepting and converting the radiation to another energy form representative of the radiation from the output side of the collimator; an electronic module is coupled to the collection module for extracting from it the converted radiation and generating therefrom an amplified and processed electrical signal which is representative of the radiation from the output face of the collimator, and an electrically addressable display module is coupled to the output side of the electronic module for receiving the output from it and generating in response thereto a two-dimensional visual display image which is representative of the radiation from the output side of the collimator, the collimator, radiation collection module, and electronic module being assembled together in a single, compact module and of such a size small enough to permit it to be held and manuevered by a human operator.
