摘要： A system for cardiac MR imaging receives a heart rate signal representing heart electrical activity. The system, over multiple successive heart cycles, uses multiple MR imaging RF coils in gradient echo imaging a patient heart, synchronized with the heart rate signal and uses an inversion recovery pulse for inverting myocardium tissue MR signal for an individual heart cycle, to acquire, within multiple individual successive portions of an individual heart cycle, corresponding successive multiple patient heart images. An individual image of an individual heart cycle portion is derived from multiple heart image representative data sets comprising a reduced set of k-space data elements acquired using corresponding multiple coils of the RF imaging coils. An image generator generates an MR image of an individual heart cycle portion using the multiple heart image representative data sets comprising the reduced set of k-space data elements.

摘要： A system and method of treating tachycardias and similar syndromes by the use of catheter ablation of tissue is described. A computed tomography (CT)-like image of the heart is obtained and processed to segment the various types of tissue. Papillary muscle areas are identified and displayed differently from the other nearby tissues so that the muscles can be avoided during treatment to avoid or minimize damage to the muscles during ablation treatment. Electrophysical data and scar tissue may also be identified in the image, which may be of the endoscopic type. The position of the catheter may be displayed as a synthetic image on the endoscopic view.

摘要： A process and system acquiring both ultrasound and MRI data from a patient in an MRI scanner and using one to automatically guide or improve the other. The ultrasound data can track the motion of an organ such as a cardiac artery or the diaphragm and the resulting motion information can automatically guide MRI data acquisition to keep the imaging volume at the organ or interest, or can be used to accept or reject MRI data in the process of forming an MRI image, based on whether the organ of interest was within an acceptable range of positions. Conversely, the MRI unit can guide the ultrasound data acquisition so it is properly timed or otherwise controlled in accordance with MRI data acquisition.

摘要： One or more techniques are provided for measuring the motion of an organ in three dimensions. As provided by the technique, the motion of the organ along each dimension may be determined by a suitable methodology. Where sensor-based motion measurements are suitable, one or more sensors may be placed on a patient to measure internal motion of the organ of interest along one or more perpendicular axes. Where image-based techniques are suitable, the motion of the internal organ along a perpendicular axis may determined using pre-acquisition image data or acquisition image data when suitable. Concurrent motion vectors for all three dimensions may be obtained from the motion data acquired for the perpendicular axes by the disparate methodologies. The concurrent motion vectors may be combined to describe the three-dimensional motion of the organ over time. Validation of the motion data may be performed for each of the one-dimensional motion data sets using motion data acquired by image-based methods, or other image-based methods, for a respective axis.
