摘要： The present invention, in one form, includes an imaging system having a x-ray source and detector array and a reconstruction algorithm. The algorithm removes overlapping structures from a patient scan so that enhanced images representing a moving heart are generated. More specifically and in one embodiment, an estimated background representing the overlapping structures is determined using the projection data. The estimated background is then subtracted from the projection data to generate filtered data. The filtered data is then used to generate an enhanced image so that cardiac calcification may be identified.

摘要： A method of obtaining in image of the phase change introduced by an object in penetrating radiation incident on the object includes irradiating the object with penetrating radiation having high lateral spatial coherence, and receiving at least a portion of the radiation at a detector after the radiation has merged from the object and thereby obtaining and storing at least two intensity records for the received radiation each including intensity values at predetermined intervals. These values are utilized to derive a grid of values defining an image of the phase change introduced by the object in the penetrating radiation. The intensity records are obtained at a uniform finite distance after the radiation has emerged from the object, and are for respective different energy distributions of the detected radiation. Apparatus is also disclosed.

摘要： A method for the reconstruction of a tomographic image of an object from measurements of scattering data resulting from probing waves. The scattering data is related to a forward scattering operator by an integral operator. The tomographic image is reconstructed by executing a prescribed mathematical algorithm, as determined with reference to the integral operator, on the scattering data.

摘要： The present technique provides a variety of processing schemes for decomposing soft tissue and bone images more accurately from low and high-energy images acquired from an imaging system, such as a dual-energy digital radiography system using flat-panel technology. In particular, a pre-decomposition process is provided for spatially matching, or registering, low and high-energy images using warping registration prior to dual energy image decomposition, which creates the soft tissue and bone images. Accordingly, the pre-decomposition process reduces motion artifacts between the low and high-energy images, thereby improving image clarity of the decomposed soft tissue and bone images.

摘要： A monitoring apparatus analyzes detector data from a CT system to detect a signature of a bad detector. The apparatus generates a plurality of Helgason-Ludwig condition values from the detector data. The generated values are processed to generate a comparison value, which is compared to a predetermined threshold value. A warning message may be generated when the comparison value exceeds the predetermined threshold value, the warning message alerting an operator to the likely presence of a bad detector. In one embodiment, the generated values are further analyzed to generate an estimate of the position of the bad detector. In a preferred embodiment, the comparison value is a matrix norm of a matrix generated from the Helgason-Ludwig condition values.

摘要： A mobile medical image scanner and teleradiology system are incorporated into an ambulance or other vehicle to permit a patient to be diagnosed while en route to a treatment facility such as a trauma center. The system obtains medical image data while the patient is being transported in the vehicle and transmits the medical image data to a receiver at a location which is remote from the vehicle. At the remote location, the transmitted medical image data is displayed in a humanly discernable manner and interpreted by a qualified physician, who then communicates diagnostic information to the technicians in the vehicle and/or to the treating physicians at the treatment facility. By providing diagnostic information back to the treating physicians prior to the patient's arrival at the treatment facility, the patient can be routed directly to the operating room, or the intensive care unit as necessary, thereby saving valuable time. The patient can even receive some care in the vehicle based on the diagnoses before he or she reaches the treatment facility. Patient survival rates are substantially improved due to the reduction in the diagnostic time required after the patient arrives at the trauma center.
