摘要： A method for imaging patient tissue using an intravascular ultrasound image includes inserting a catheter into a patient blood vessel. The catheter includes at least one transducer configured and arranged for insertion into a lumen of the catheter. Acoustic signals are transmitted from the at least one transducer along a series of scan lines towards patient tissue between incremental rotations of the at least one transducer. The transmitted acoustic signals include first acoustic signals having first frequency bandwidths centered at a first center frequency and second acoustic signals having second frequency bandwidths centered at a second center frequency. Corresponding echo signals reflected from patient tissue are received, transformed, processed, and displayed.

摘要： A method of evaluating at least one tissue type includes providing a tissue classifier comprising multiple detector arrays for each of multiple tissue types. Each detector array comprises multiple detectors and each detector comprises multiple tissue type-assigned intravascular ultrasound (IVUS) spectra. A plurality of the tissue type-assigned IVUS spectra of each detector correspond to a tissue type of the detector and a plurality of the tissue type-assigned IVUS spectra correspond to other tissue types. For each of the detector arrays, an input IVUS spectrum of the tissue region is compared to the tissue type-assigned IVUS spectra of each of the detectors in the detector array. For each of the detectors, it is determined whether the input spectrum corresponds to the tissue type of the detector based on the comparisons of the input spectrum to the tissue type-assigned spectra for that detector. For each of the detector arrays, results of the detectors of the detector array are combined to produce an array result. The array results for the detector arrays are combined to provide a tissue characterization of the tissue region from the multiple tissue types. This is repeated for each region to be characterized. A size of at least one of the tissue types is determined using the tissue characterizations. One or more IVUS images can be displayed with the tissue characterization and an indication of the size of at least one of the tissue types in a selected portion of the image that is displayed.
