IMAGE-GUIDED THERAPY OF A TISSUE

摘要

Image-guided therapy of a tissue can utilize magnetic resonance imaging (MRI) or another medical imaging device to guide an instrument within the tissue. A workstation can actuate movement of the instrument, and can actuate energy emission and/or cooling of the instrument to effect treatment to the tissue. The workstation and/or an operator of the workstation can be located outside a vicinity of an MRI device or other medical imaging device, and drive means for positioning the instrument can be located within the vicinity of the MRI device or the other medical imaging device. The instrument can be an MRI compatible laser or high-intensity focused ultrasound probe that provides thermal therapy to, e.g., a tissue in a brain of a patient.

主权项

1. A method for effecting thermal therapy using an in vivo side fire probe, comprising:
positioning the side fire probe in a volume in a patient at a target position; identifying a three-dimensional region of interest at which to apply thermal therapy; and delivering, by processing circuitry, thermal therapy to the three-dimensional region of interest, wherein delivering thermal therapy comprises
a) activating emissions exiting the side fire probe to at a high power output for a first period of time,b) deactivating emissions exiting the side fire probe for a second period of time, andc) repeating steps a) and b) until determining completion of thermal therapy; wherein
determining completion of thermal therapy comprises at least one of i) identifying the three-dimensional region of interest has reached a target temperature, and ii) identifying a thermal dose that is based on a temperature history of the three-dimensional region of interest over a specified time period.
