Abstract: Apparatus, techniques and systems are described for facilitating identification of a target area during a probe-guided radio-localization surgical procedure. The described apparatus, techniques and systems can be used to implement a nuclear-uptake mode controller integrated into a probe to allow a user to instantly switch between multiple nuclear-uptake modes directly from the probe hand-piece. For example, a nuclear-uptake mode controller integrated into the probe can be used to instantly switch between a high-sensitivity nuclear uptake mode and a high-resolution nuclear-uptake mode to effectively identify the target area in the presence of interfering nuclear signals by better matching the probe's nuclear detection parameters to a search task for that target area.

Abstract: A virtual-reality method for surgical training simulates the task of detecting sentinel lymph nodes using a nuclear uptake probe. The simulator can be used with lymphoscintigraphic clinical imaging data to provide patient-specific training scenarios. In yet another embodiment, the apparatus can use a database representing mathematical phantoms to simulate different patient sizes, node distributions, node uptakes, and combinations thereof.

Abstract: A SPECT system which scans over multiple separate scans and individually motion compensates the information obtained from each of these scans. The separate scans may be over different angular extents and may be for different purposes. One of the scans for example may be a scout scan, and the other scans may then be scans which concentrate on areas identified during the scout scan. Alternatively, the scans may all being exactly the same and stitched together after the individual motion compensation. Since each of the scans are shorter, the patient will presumably have moved less during each individual scan, and the amount of motion is hence presumably less.

Abstract: A large field of view projection image is obtained and a small field of view projection image is obtained. The two images are normalized, to take into account the difference between the count data between the images, and the way the images represent data. The large field of view image does not include truncation errors that are present in the small field of view image and therefore is stitched together with the smaller field of view image to use the improved data within the small field of view image with the truncation reduction enabled by the larger field of view image.

Abstract: A multiaxis gantry camera has additional axes of movement that allow unexpected functions. A first function allowed the collimator is to be exchanged while maintaining them in a configuration that saves space. The device can also be used to calibrate in a space-saving configuration. Different turning configurations can be allowed to change the orientation over which scanning is conducted.

Abstract: Undesired effect reduction in a medical image. A set of medical images corresponding to a number of images each taken at a different time and from plural different projection views are obtained. The images are analyzed to determine which images in the set have effects from an undesired effect, such as patient movement or attenuation due to an organ. The undesired images are removed to form a subset which may be a subset over a specified angle range, or just certain images within the subset. The medical analysis is carried out on the subset of images.

Abstract: An image from a gamma camera, e.g., from a radiopharmaceutical, is corrected for scatter. The image is approximated by estimating the center of the organ and supposing a Guassian response that is scatter-corrected.

Abstract: A medical imaging system, e.g., a computed tomography system includes at least one radiation detector that is relatively rotatable with respect to an object of interest. The angular range is divided into discrete continuous acquisition ranges and unsampled angular ranges, wherein the discrete continuous acquisition ranges are separated by unsampled angular ranges.

Abstract: Medical imaging information is randomly resampled into the new resampled form. The random resampling can maintain the random nature of the information, and can avoid count loss.

Abstract: Separated medical detector heads for medical single particle imaging, are all located clustered together at one end of an arc, e.g., over 202.5° or 180° of arc. The entire patient can still be imaged, but the patient can enter and exit the imaging area without going between the heads.

Abstract: A multiheaded camera which is formed with a number of heads on one support structure and a different support structure with other heads. At least one of the heads is movable, so that the patient can obtain ingress and egress to the area.

Abstract: A vehicle ramp system for elevating a vehicle off the ground. Tires on one end of a vehicle are driven onto a first set of modified ramps. Each of the modified ramps has an extended elevated horizontal platform and the vehicle's tires are rolled to the terminal end of the elevated platform of the first set of ramps. A second set of ramps is then placed on the opposite side of a second set of tires that are provided on the opposite end of the same vehicle. The vehicle is then reversed in direction so that the second set of tires rolls up onto the second set of ramps until the second set of tires rest on elevated platforms provided on the second set of ramps and the first set of tires are retained on the platform of the first set of ramps.

Abstract: A detector head having a small field of view, for example one which receives information from less than half a body imaged, is used to form a transmission attenuation map. The same detector head both receives information for the transmission attenuation map and also receives imaging information e.g. from a radioisotope.
