Abstract
For catheter-based ultrasound probes, a compensator is included as part of the imaging catheter. The compensator counters the thrust or other motion of the imaging catheter, physically stabilizing the imaging catheter during imaging of the patient. Recoil compensation may result in more accurate and/or less blurred ultrasound imaging from a catheter.
Claims20
An ultrasound imaging catheter comprising:
- a catheter housing configured for insertion into a patient;
- a first one-dimensional array of elements within the catheter housing, the first one-dimensional array configured for ultrasound imaging of the patient;
- and
- an acoustic transducer within the catheter housing, the acoustic transducer facing in a different direction than the first one-dimensional array, wherein the acoustic transducer is configured for recoil compensation due to operation of the first one-dimensional array.
1 more element
A method for ultrasound imaging with a catheter probe, the method comprising:
- imaging a patient with an imaging array in the catheter probe, the imaging comprising transmitting a first focused acoustic pulse from the imaging array, the transmission of the first focused acoustic pulse causing a recoil motion force on the imaging array;
- and
- countering the motion force by transmitting a second acoustic pulse from a separate acoustic transducer within the catheter probe during the imaging, wherein the second acoustic pulse comprises unfocused, defocused, and/or diffused acoustic energy transmitted in a direction opposite to the recoil motion force.

An ultrasound imaging catheter comprising:
- a catheter housing configured for insertion into a patient;
- a one-dimensional array of elements within the catheter housing, the one-dimensional array configured for ultrasound imaging of the patient by transmitting a first acoustic radiation force impulse causing a recoil motion force on the catheter housing;
- and
- a recoil compensator configured to limit recoil motion force of the catheter housing due to operation of the one-dimensional array by transmitting a second acoustic pulse in a direction opposite to the recoil motion force.
