| 20080240343 | Portable digital tomosynthesis imaging system and method - A portable tomosynthesis imaging system is disclosed that includes a portable X-ray source assembly and a portable detector assembly. The source assembly may be coupled to a portable power supply and controller such that multiple projection X-ray images may be obtained at a site that is not accessible by conventional tomosynthesis imaging systems. Image data may be transmitted from the detector by wired or wireless communication. Tomosynthesis image reconstruction may be performed locally at the portable system or remotely by the transmission of raw or filtered image data from the portable system. The portable system is particularly well-suited to field deployment, such as at accident scenes, scenes of natural or other disasters, or in confined clinical settings. | 10-02-2008 |
| 20080240357 | Image acquisition and processing chain for dual-energy radiography using a portable flat panel detector - A mobile dual-energy X-ray imaging system is presented. The mobile dual-energy X-ray imaging system is a digital X-ray system that is designed both to acquire original image data and to process the image data to produce an image for viewing. The system has an X-ray source and a portable flat-panel digital X-ray detector. The system is operable to produce a high energy image and low energy image, which may be decomposed to produce a soft tissue image and a bone image for further analysis of the desired anatomy. The system is disposed on a carrier to facilitate transport. The imaging system has an alignment system for facilitating alignment of the flat-panel digital detector with the X-ray source. The imaging system also comprises an anti-scatter grid and an anti-scatter grid registration system for removing artifacts of the anti-scatter grid from images. | 10-02-2008 |

| 20090092307 | SLIT COLLIMATOR SCATTER CORRECTION - A technique is presented for establishing a patient's BMD using a dual-energy X-ray imaging system. In the technique, the dual-energy X-ray imaging system utilizes a slit collimator to expose a series of portions of a region of interest within a patient with X-rays of two different energies. A flat-panel digital X-ray detector detects the X-rays passing through the patient's region of interest and produces data representative of the intensity of the X-rays reaching the detector. The image intensity data is corrected for scatter based on identifying the regions of the image intensity data that are produced from scatter only, and not primary X-rays. A first-order derivative of the image intensity data is used to identify these regions. A value for the intensity of the scatter at the boundary of the scatter-only region is established. The value for the intensity of the scatter at the boundary of the scatter-only region is used to estimate scatter intensity in the region of the image intensity data that is produced from primary X-rays, as well as scatter. To correct the image intensity data for scatter, the known and estimated scatter intensities are subtracted from the image intensity data. | 04-09-2009 |
| 20090103679 | IMAGE GUIDED ACQUISITION OF QUANTITATIVE DUAL ENERGY DATA - A technique for establishing texture metrics and bone mineral density (BMD) within an anatomical region of interest. A digital imaging system is used to acquire a standard digital X-ray image with a wide field of view. The standard digital X-ray image is used to guide the imaging system to obtain an image of a region of interest. The standard digital X-ray image is used to calculate various texture metrics, such as a length of a fracture. A dual-energy digital X-ray image of the region of interest is acquired. The dual-energy digital X-ray image is corrected for scatter. The BMD of the region of interest may be established from the scatter-corrected dual-energy digital X-ray image. The BMD, the texture metrics, and/or the scatter-corrected dual-energy X-ray image may be displayed on the standard digital X-ray image. | 04-23-2009 |

| 20090136111 | SYSTEM AND METHOD OF DIAGNOSING A MEDICAL CONDITION - A system and method of diagnosing a medical condition in a patient from accessing image data and non-image data of a patient, analyzing the combination of image data and non-image data to generate an output with image findings and a risk assessment for diagnosing certain medical conditions in the patient. The image data may be acquired from an image acquisition system. The non-image data may include clinical data of the patient and may be acquired from a user interface, an electronic medical record, and/or findings from an expert system from previous imaging sessions. | 05-28-2009 |
