A system for describing the physical distribution of an agent that accumulates selectively in tissue of a patient in an excised surgical specimen. The system comprises an agent which selectively concentrates in a cancer or precancer or focus of infection or other pathological condition. The system comprises a detector sensitive to the agent which is present in the surgical specimen. The system also comprises an apparatus capable of forming an image based on the information gathered by the detector, and which image describes the physical distribution of the agent in the surgical specimen so that a surgeon can be guided by the image provided by the apparatus, said apparatus connected to said detector.

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.

A tomographic imaging system includes a moveable detector or detectors capable of detecting gamma radiation; one or more position sensors for determining the position and angulation of the detector(s) in relation to a gamma ray emitting source; and a computational device for integrating the position and angulation of the detector(s) with information as to the energy and distribution of gamma rays detected by the detector and deriving a three dimensional representation of the source based on the integration. A method of imaging a radiation emitting lesion located in a volume of interest also is disclosed.

A system and a method for determining a biopsy location in a body part are provided. The system includes a first device configured to obtain digital physiological image data about the body part, a second device configured to obtain anatomical image data about the body part, a monitor configured to display the anatomical image data, a signal processing module that includes an analog-to-digital converter configured to digitize the anatomical image data, a memory configured to store the digital physiological image data and the digitized anatomical image data, and a correlator coupled to the memory and configured to correlate the digital physiological image data with the digitized anatomical image data and to produce a combined image as a result of the correlation. A determination of a biopsy location is made on the basis of the combined image. The first device may include a positron emission tomography scanner machine. The second device may include one of the group consisting of a digital x-ray machine, an x-ray mammography machine, an x-ray cranial axial tomography machine, a magnetic resonance imaging machine, and an ultrasound machine. The system may also include a localization device, such as a computer mouse, that is configured to select a preferred subset of the second image data based on the digital physiological image data. The first device may be configured to use a predetermined spatial coordinate system. The correlator may include a transformer configured to transform the data into the predetermined spatial coordinate system.

A system and a method for obtaining an image of a body part within a body are provided. A radiotracer including Indium-111 is administered to the body part. The system includes a first gamma ray sensor and a second gamma ray sensor, each being configured to detect prompt gamma rays emitted by Indium-111. The first gamma ray sensor is positioned external to the body, and the second gamma ray sensor is positioned either internally within the body or within a body orifice or body cavity. A relative position of the second gamma ray sensor with respect to the first gamma ray sensor may be known. The respective detections of gamma rays by the first and second gamma ray sensors may be used to determine a distribution of radioactive source material in the body part. The radiotracer may also include a positron emitter. The first and second gamma ray sensors may be configured to detect substantially coincident gamma rays emitted as a result of a positron annihilation event.

An apparatus and a method for implementing emission tomography of a compressed and/or immobilized body part with open access for interventions, such as biopsy, hook-wire placement, or minimally invasive therapy, are provided. The apparatus includes one or more holders that compress and/or immobilize the body part on one or more sides of the body part. One or more of the holders contains an aperture through which an intervention can be carried out. Affixed to one or more holders are mechanical stages that carry and move a gamma-ray detector or detectors across the body part, so that the gamma-ray detector(s) can at times stay on the mechanical stages in a position that does not interfere with interventions through the aperture in the body part holder(s). A safety door mechanism is affixed to the aperture in the body part holder(s) in order to prevent the gamma-ray detector(s) from coming into physical contact with one or more portions of the body part that might otherwise protrude through the aperture.

An electromagnetic structure is fabricated by additive manufacturing having at least one channel traversing the structure. In one embodiment, at least one form contains apertures and/or holes forming the channel and a liquid metal traverses the structure by the channel. Electrodes are provided to apply or extract electrical voltage or power to and/or from the liquid metal as well as a mechanism for propelling a portion of the liquid metal through the form. In an alternative embodiment, both the electrically insulating and the electrically conductive materials are solid and the channel is used for conducting a coolant instead of the liquid metal.
