Abstract
A radiation finder tool assists in locating tissue of interest within a patient. The radiation finder tool includes a body and a plurality of radiation detectors. The body has a distal end, a proximal end. A lengthwise axis of the radiation finder tool extends between the proximal end and the distal end of the body. The plurality of radiation detectors is oriented serially along the lengthwise axis, e.g., stacked one after the other along the lengthwise axis. Each radiation detector of the plurality of radiation detectors has a different field of view for radiation detected by that radiation detector. Each field of view of the plurality of radiation detectors has the lengthwise axis at its center.
Claims20
A radiation finder tool comprising:
- a body;
- a first gamma radiation detector mounted in the body;
- a collimator in the body, the collimator having a proximal end and a distal end, the proximal end of the collimator being proximal to the first gamma radiation detector;
- and
- a second gamma radiation detector mounted in the body, the second gamma radiation detector being configured to receive gamma radiation passed through the first gamma radiation detector and the collimator.
A radiation finder tool comprising:
- a body having a distal end, a proximal end, and a lengthwise axis extending between the proximal end and the distal end of the body;
- a first radiation detector mounted in the body, the first radiation detector having a first area in a plane substantially perpendicular to the lengthwise axis;
- a collimator in the body, the collimator having a proximal end and a distal end, the proximal end of the collimator being proximal to the first radiation detector;
- and
- a second radiation detector mounted in the body, the second radiation detector being configured to receive radiation passed through the first radiation detector and the collimator, the second radiation detector having a second area in a plane substantially perpendicular to the lengthwise axis, wherein the second area of the second radiation detector is smaller than the first area of the first radiation detector.
A radiation finder tool comprising:
- a body having an outer surface;
- a first radiation detector mounted in the body;
- a collimator in the body, the collimator having a proximal end and a distal end, the proximal end of the collimator being proximal to the first radiation detector;
- a second radiation detector mounted in the body, the second radiation detector being configured to receive radiation passed through the first radiation detector and the collimator;
- a first visual radiation detection indicator mounted on the outer surface of the body and coupled to the first radiation detector;
- and
- a second visual radiation detection indicator mounted on the outer surface of the body and coupled to the second radiation detector.
