Abstract:
A compact medical imaging device, comprising:a collimator for collimating radiation emanating from a radiopharmaceutical 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 input and output sides and parallel to the collimation axis; a radiation collection module having 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, thereby providing converted radiation; an electronics module coupled to the collection module for receiving the converted radiation and generating therefrom at least one electrical signal which is representative of the radiation from the output side of the collimator; an electrically addressable display module coupled to the electronics module for generating a two-dimensional visual display image which is representative of the radiation from the output side of the collimator; and a marking device for correlating a location in the displayed image to a location on the surface of the subject; the collimator, radiation collection module, and display module being assembled together in a single, compact module of a size small enough to permit the compact module to be held and maneuvered by a human operator.
