ABSTRACT:
A biopsy probe for detecting radiation emanating from a hidden source in a patient. The probe comprises a body member formed of a radiation blocking material and having a distal end portion and a proximal end portion. The proximal end portion is arranged to be held in the hand of a user. The probe comprises a radiation detector, e.g., a scintillation crystal, located within the distal portion of body member, a first radiation transparent window located at the distal end of the body member confronting the detector and through which radiation may pass to the detector, and a passageway extending through the distal end portion of the body member centered in the window and the detecting means. The passageway is arranged to guide a thin instrument, e.g., a biopsy needle, therethrough when the distal end portion is oriented in a direction toward the hidden source of radiation. A disposable cover/shield is also provided for releasable securement to the distal end of the probe to protect it from contamination. A collimator is also provided for releasable securement to the probe to reduce the probe's field of view.
