摘要： The present invention relates to a method to measure, record, analyze, and report cumulative radiation exposure to the patient population and provide automated feedback and recommendations to ordering clinicians and consultant radiologists. The data provided from this "radiation scorecard" would in turn be automatically recorded into a centralized data repository (radiation database), which would be independent to the acquisition site, technology employed, and individual end-user. Retrospective analysis can also be performed using a set of pre-defined scorecard data points tied to the individual patient's historical medical imaging database, thereby allowing for comprehensive (both retrospective and prospective) medical radiation exposure quantitative analysis. Patient safety can be improved by a combination of radiation dose reduction, exposure optimization, rigorous equipment quality control (QC), education and training of medical imaging professionals, and integration with computerized physician order entry (CPOE).

摘要： A method of determining the distribution of radioactive material within a region is. described. A plurality of radiological measurements and associated geometrical measurements taken at a plurality of positions in said region are input to a computer system. A 3D model of structures within said region is defined and the position within the model of each radiation measurement is obtained by using the geometrical measurements. The radiological measurements are then ascribed to a distribution of sources restricted to defined locations in the 3D model. The source distribution is parameterised over the defined source locations, and each parameter is related to the calculated observable radiation field, calculated using a physical model, at each measurement position. The parameters are adjusted to optimize the correspondence between the actual radiological measurements and the calculated observable radiation field, to yield the distribution of radioactive material as defined by the adjusted parameters.

摘要： Digital images or the charge from pixels in light sensitive semiconductor based imagers are used to detect gamma rays and energetic particles emitted by- radioactive materials. Methods may be used to identify pixel-scale artifacts introduced into digital images and video images by high energy gamma rays. Statistical tests and other comparisons on the artifacts in the images or pixels may be used to prevent false-positive detection of gamma rays. The sensitivity of the system may be used to detect radiological material at distances in excess of 50 meters. Advanced processing techniques allow for gradient searches to more accurately determine the source's location, while other acts may be used to identify the specific isotope. Coordination of different imagers and network alerts permit the system to separate non- radioactive objects from radioactive objects.

摘要： The invention provides improved methods and apparatus for investigating emissions from radioactive sources within an environment. In particular, the method deploys a collimated detector to scan the environment and obtain approximate position information on sources within that environment together with further investigations using a moveable shielding component which is moved relative to the field of view of the collimator. In an alternative technique, the collimator is moved in two different directions to achieve positional information using scanning.
