摘要： A computer-implemented method is disclosed for comparing three dimensional (3D) digital medical images. The method uses a reference MPR to position subsequent MPRs in one or more other 3D digital medical images so their content matches the reference MPR. The matched MPRs may then be used by a medical professional to diagnose a patient condition. The ability to quickly and automatically position matching MPRs for multiple 3D images eases the medical staff workload and shortens diagnostics time. Matching MPRs provides an effective way to view the 3D volumes for anatomical changes over time and to monitor medical conditions such as stenosis and tumors.

摘要： A method for real-time cardiac visualization includes acquiring fluoroscope imagery from two planes. The location of at least one electrophysiology (EP) device is marked within the fluoroscope imagery from each of the two planes. The location information for the at least one EP device is combined within each of the acquired fluoroscope images from the two planes to determine a 3D location for the at least one EP device. The fluoroscope imagery from at least one of the two planes is displayed with a visual aid superimposed thereon. The visual aid is based on the 3D location of the EP device.

摘要： A method for three-dimensional esophageal reconstruction includes acquiring a first X-ray image from a first angle with respect to a subject using a first X-ray imager. At least a second X-ray image is acquired from a second angle, different than the first angle, with respect to the subject using a second X-ray imager. Additional X-ray images may be acquired from additional angle. A three-dimensional model of the esophagus is generated from the at least two X-ray images acquired at different angles. A set of fluoroscopic X-ray images is acquired using either the first X-ray imager or the second X-ray imager. The three-dimensional model of the esophagus is registered to the acquired set of fluoroscopic X-ray images. The three-dimensional model of the esophagus is displayed overlaying the set of fluoroscopic X-ray images.
