Abstract
The present disclosure relates, in part, to a scanning sufficiency apparatus that computes whether a handheld scanning device has scanned a volume for a sufficiently long time for there to be detections and then indicate to the user that the time is sufficient in 3-D rendered voxels. Also described is a hand held medical navigation apparatus with system and methods to map targets inside a patient's body.
Claims30
A scanning sufficiency apparatus, comprising:
- an ionizing radiation sensor within a housing assembly;
- a tracking system providing a position and orientation of the sensor with respect to an examined object;
- at least one processor;
- and
- a memory operatively coupled with the sensor, the at least one processor, and the tracking system, the memory having instructions for execution by the at least one processor configured to:
- associate scanning data from the sensor with the position and orientation of the sensor with respect to the examined object to create registered scans;
- separate an adjacent volumetric space into three-dimensional (3D) imaging elements;
- produce a 3D model of radioactive sources by combining the registered scans;
- and
- calculate a scanning completeness of a particular 3D imaging element to obtain a scanning completeness value (SCV),
- wherein the calculation of the SCV uses the sensor tracking information to determine partial volumes that have been scanned enough and partial volumes that have not been scanned enough for a defined scanning objective.

A scanning sufficiency apparatus, comprising:
- a detector;
- a tracking camera rigidly attached to the detector and being a known proximity to the detector;
- at least one processor;
- and
- a memory operatively coupled with the detector, the at least one processor, and the tracking camera, the memory having instructions for execution by the at least one processor configured to:
- calculate a spatial position and orientation of the tracking camera with respect to a subject to create tracking data;
- associate scanning data from the detector with the calculated spatial position and orientation of the tracking camera to determine a position and orientation of the scanning data using the known proximity of the detector to the tracking camera;
- produce a three dimensional (3D) model of the subject using one or more signals detected by the detector and the position and orientation of the scanning data;
- and
- separate the 3D model into imaging elements,
- wherein a scanning completeness of a particular imaging element is determined by calculating a scanning completeness value (SCV), and
- wherein the calculation of the SCV uses the tracking data.

A method for performing an optimized scan of a subject, the method comprising:
- scanning the subject with a detector;
- tracking the detector to provide a position and orientation of the detector with respect to an examined object;
- associating scanning data from the detector with the position and orientation of the detector with respect to the examined object to create a registered scan;
- separating an adjacent volumetric space into 3D imaging elements;
- producing a 3D model of the subject by combining the registered scans;
- and
- calculating a scanning completeness of a particular 3D imaging element to obtain a scanning completeness value (SCV),
- wherein the calculation of the SCV uses the detector tracking information to determine partial volumes that have been scanned enough and partial volumes that have not been scanned enough for a defined scanning objective.
