US 9,066,674 B2 · Motion synchronized destruction for three-dimensional reperfusion mapping in medical diagnostic ultrasound imaging

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.

Dependent claims

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.
