Abstract
The invention relates generally to biopsy needle guidance which employs an x-ray/gamma image spatial co-registration methodology. A gamma camera is configured to mount on a biopsy needle gun platform to obtain a gamma image. More particular, the spatially co-registered x-ray and physiological images may be employed for needle guidance during biopsy. Moreover, functional images may be obtained from a gamma camera at various angles relative to a target site. Further, the invention also generally relates to a breast lesion localization method using opposed gamma camera images or dual opposed images. This dual head methodology may be used to compare the lesion signal in two opposed detector images and to calculate the Z coordinate (distance from one or both of the detectors) of the lesion.

21. An apparatus for determining lesion location within a target site in a patient, comprising:
-
at least one photon imaging device, wherein said at least one photon imaging device is movable with respect to the target site such that said at least one photon imaging device acquires a plurality of images relative to the target site, wherein a signal intensity for the plurality of images is obtained from opposed positions; and a controller configured to; control movement of said at least one photon imaging device; receive images from said at least one photon imaging device and to receive the signal intensity for each of the plurality of images; and calculate the lesion location within the target site in the patient based upon the plurality of images acquired by said at least one imaging device using the obtained signal intensities from only a single set of mutually opposing positions. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. An apparatus for determining lesion location within a target site in a patient, comprising:
-
means for receiving a plurality of images using photon imaging of the target site from a single set of opposing positions; means for receiving a measured signal intensity simultaneously at each opposing positions; and means for calculating a lesion spatial location within the target site based upon the acquired plurality of images and based upon a comparative signal intensity calculated using the received measured signal intensities at the single set of opposing positions. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
