Motion synchronized destruction for three-dimensional reperfusion mapping in medical diagnostic ultrasound imaging
First Claim
1. A method for motion synchronized destruction for reperfusion in medical diagnostic ultrasound, the method comprising:
- acquiring a plurality of ultrasound frames of data, representing, at least in part, information from contrast agents in a three-dimensional region of a patient;
determining a registration level as a similarity between data from different times within the plurality;
transmitting, at a time during acquiring the plurality, acoustic energy with an amplitude for destruction of the contrast agents;
synchronizing the transmitting with the registration level such that the transmitting occurs where the registration level is on a first side of a first level of the registration and does not occur where the registration level is on a second side of the first level of the registration; and
generating an image as a function of a level of contrast agents, the level of contrast agents being of the contrast agents after the transmitting.

Abstract
Destruction for reperfusion in medical diagnostic ultrasound is synchronized to motion. Perfusion data for a volume is acquired sequentially for different segments of the volume. For a given segment, such as a planar region, motion tracking within the segment is performed. If sufficient registration or correlation exists at the completion of a sequence of scans for the current segment, then a lesser amount of movement is occurring. At this point, the transmission of contrast agent destructive acoustic energy is performed in the next segment. Tracking is repeated for the next segment to synchronize the switch to yet another segment. Other regions for tracking can be used. By controlling transmission of destruction pulses, more reliable perfusion quantities in a volume may be determined.

20. A method for motion synchronized destruction for reperfusion in medical diagnostic ultrasound, the method comprising:
-
scanning, with ultrasound from a transducer, first and second different portions of a volume of a patient, the first portion scanned a first plurality of times and then the second portion scanned a second plurality of times; destroying contrast agents in the first portion prior to the scanning of the first plurality of times; destroying contrast agents in the second portion prior to the scanning of the second plurality of times and after the scanning of the first portion; correlating data representing the first portion from the first plurality of scans; performing the destroying of the contrast agents in the second portion where the correlating indicates a threshold amount of correlation.
