Ultrasound for Therapy Control or Monitoring
First Claim
1. A system for therapy control with an ultrasound scanner, the system comprising:
- transmitters of the ultrasound scanner, the transmitters operable to scan with beams of ultrasound in a scan sequence;
a processor of the ultrasound scanner, the processor configured to create the scan sequence for the ultrasound scanner as a function of a therapy plan and to turn off the transmitters for at least a portion of the scan sequence; and
a trigger output of the ultrasound scanner configured to output triggers to a therapy device, the output triggers responsive to the scan sequence.

Abstract
Therapy control and/or monitoring is performed with an ultrasound scanner. The ultrasound scanner detects temperature to monitor therapy, and perform HIFU beam location refocusing of the therapy system based on the temperature. The monitoring is synchronized with the therapy using a trigger output of the ultrasound scanner. The trigger output responds to a scan sequence of the ultrasound scanner. To meet a given therapy plan, the scan sequence is customized, resulting in the customized trigger sequence. Three dimensional or multi-planar reconstruction rendering is used to represent temperature for monitoring feedback. The temperature at locations not being treated may be monitored. If the temperature has an undesired characteristic (e.g., too high), then the therapy is controlled by ceasing, at least temporarily.

17. In a non-transitory computer readable storage medium having stored therein data representing instructions executable by a programmed processor for therapy monitoring with an ultrasound scanner, the storage medium comprising instructions for:
-
acquiring temperatures of tissue in locations distributed in three-dimensions; interleaving therapeutic transmissions with the acquiring of the temperatures; receiving user input of rendering manipulation; and generating, in real time with the therapeutic transmissions, a three-dimensional or a multi-planar reconstruction rendering to a two-dimensional image of the temperatures, the rendering being a function of the rendering manipulation. - View Dependent Claims (18, 19)

20. In a non-transitory computer readable storage medium having stored therein data representing instructions executable by a programmed processor for therapy control with an ultrasound scanner, the storage medium comprising instructions for:
-
transmitting therapeutic high intensity focused ultrasound to a treatment region within a patient region; acquiring temperatures of tissue in locations distributed in the patient region, at least some of the locations outside of the treatment region; and ceasing the transmitting of the therapeutic high intensity focused ultrasound based on at least one temperature for at least one of the locations outside the treatment region. - View Dependent Claims (21)
