摘要： A method and apparatus for using a flat panel detector to determine bone mineral density are provided. The apparatus includes a dual energy X-ray emitter, a flat panel detector for receiving X-rays sent from the X-ray emitter, and may optionally include an image corrector, adapted to emit corrected image information. The apparatus also includes a basis material decomposer that includes a calibration database, the decomposer being adapted to create a bone image and a soft tissue image. The apparatus further includes a bone mineral density calculator that is adapted to compute bone mineral density from the first image, and a display for displaying at least the computed bone mineral density. A method for using a flat panel detector to detect multiple disease states is also provided. The method includes emitting X-rays from a dual energy X-ray source through an area of a patient's body sought to be imaged and receiving X-rays with a flat panel detector. The method also includes generating multiple images, using dual energy X-ray absorptiometry, to detect for a first disease state and a second disease state and analyzing the images for the first and second disease states. The first disease state includes lung cancer, breast cancer, pneumonia, chronic obstructive pulmonary disease, tuberculosis, bone fracture or an abnormally sized or shaped organ and the second disease state comprises osteoporosis.

摘要： The presently described technology provides a tomosynthesis imaging system that comprises an x-ray tube and an anti-scatter grid. The x-ray tube is configured to emit x-rays from a plurality of positions during movement of the x-ray tube along a long axis of a mobile patient surface. The anti-scatter grid is configured to filter out scattered x-rays and includes a grid line parallel to the long axis of the mobile patient surface. The x-rays emitted from the plurality of positions are reconstructed into at least one image of at least one plane of a patient anatomy. The described technology is useful in emergency or trauma applications where a patient may be quickly and easily moved on a mobile patient surface to a position near an x-ray detector used in combination with the x-ray tube and anti-scatter grid.

摘要： A method and system which may be used to display a number of computer-detected regions of pathological interest using interactive CAD markers are presented. In one embodiment, a layer of uniquely identified CAD markers corresponding to computer-detected regions of pathological interest of an anatomical feature may be simultaneously displayed with an image of the anatomical feature. Each individual CAD marker may be configured to incorporate viewable classification data entered by a user and may further be configured to visually indicate the probability of cancer determined by the CAD algorithm. Each individual CAD marker and the information associated therewith may also be saved with the image such that it may be incorporated into, for example, a structured reporting system.
