Abstract
A nuclear medicine camera 10 and method of use photographically record radioactive decay particles emitted from a source, for example a small, previously undetectable breast cancer, inside a patient. The camera 10 includes a flexible frame 20 containing a window 22, a photographic film 24, and a scintillation screen 26, with or without a gamma-ray collimator 34. The frame 20 flexes for following the contour of the examination site on the patient, with the window 22 being disposed in substantially abutting contact with the skin of the patient for reducing the distance between the film 24 and the radiation source inside the patient. The frame 20 is removably affixed to the patient at the examination site for allowing the patient mobility to wear the frame 20 for a predetermined exposure time period. The exposure time may be several days for obtaining early qualitative detection of small malignant neoplasms.
