Dedicated apparatus and method for emission mammography
First Claim
1. A method for examining a body part comprising the steps of:
- immobilizing and compressing the body part to provide reproducible localization of an area of interest in the body part and to improve diagnostic quality of an image of the body part; and
obtaining at least one physiological image of the body part, wherein the body part is a prostate.

Abstract
The present invention is an apparatus for examining a body part. The apparatus comprises a mechanism for immobilizing and compressing the body part. The apparatus also comprises a mechanism for providing an internal anatomical image of the body part and a mechanism for detecting single gamma-rays emitted by a radiotracer infiltrated into the body part. The detecting mechanism is disposed in an adjacent relationship with the mechanism for providing an internal anatomic image so that the body part remains in the same position during and between anatomic and radiotracer imaging. In one embodiment, the detecting mechanism includes a detector module disposed on one side of the immobilizing mechanism. The detector module preferably has at least one array of gamma ray sensitive material in communication with a position detector. In another embodiment, the detecting mechanism includes a pair of detector modules disposed one on each side of the immobilizing mechanism. The present invention is also an apparatus for examining a body part which comprises a mechanism for immobilizing and compressing the body part and a mechanism for providing a stereotactic internal anatomical image of the body part. The apparatus also comprises a mechanism for providing a stereotactic physiological image of the body part in an adjacent relationship with the mechanism for providing an internal anatomic image such that the body part remains in the same position during and between stereotactic anatomic and radiotracer imaging.

4. A method of examining a body part, comprising the steps of:
-
injecting a patient with an agent whose concentration in the body part reflects the presence of malignant cells in the body part, said agent being a source of signal;
immobilizing and compressing the body part to provide reproducible localization of a lesion in the body part and to improve diagnostic quality of an image of the body part;
placing a detector capable of detecting signals emitted by the agent in proximity to the body part; and
obtaining an image that displays the physiology of said body part based on signals emitted by the agent, wherein the body part is a prostate. - View Dependent Claims (5, 6)

7. A method for examining a body part having tissue containing malignant cells, comprising the steps of:
-
injecting a patient with an agent whose concentration in the body part depends on the physiological processes in the body part, said agent being a source of signal;
immobilizing and compressing the body part to provide reproducible localization of an area of interest in the body part and to improve diagnostic quality of an image of the body part;
obtaining an internal anatomical image of the body part;
placing a detector capable of detecting signals emitted by the agent in proximity to said body part; and
obtaining an image that displays the physiology of said body part based on signals emitted by the agent, wherein the body part is a prostate. - View Dependent Claims (8, 9, 10)
