  • MRI-BASED FEEDBACK CONTROL OF ULTRASOUND BASED MECHANICAL FRACTIONATION OF BIOLOGICAL TISSUE
    Publication number: 20220304588
    Abstract: Disclosed herein are example embodiments of devices, systems, and methods for mechanical fractionation of biological tissue using magnetic resonance imaging (MRI) feedback control. The examples may involve displaying an image representing first MRI data corresponding to biological tissue, and receiving input identifying one or more target regions of the biological tissue to be mechanically fractionated via exposure to first ultrasound waves. The examples may further involve applying the first ultrasound waves and, contemporaneous to or after applying the first ultrasound waves, acquiring second MRI data corresponding to the biological tissue. The examples may also involve determining, based on the second MRI data, one or more second parameters for applying second ultrasound waves to the biological tissue, and applying the second ultrasound waves to the biological tissue according to the one or more second parameters.

  • High-intensity focused ultrasound for heating a target zone larger than the electronic focusing zone
    Patent number: 11116405
    Abstract: The invention provides for a medical instrument (200) comprising a magnetic resonance imaging system (202) and a high-intensity focused ultrasound system (204) with an electronically controllable and a mechanically controllable focus.
    Type: Grant

  • Therapeutic apparatus and method for heating a subject
    Patent number: 10099069
    Abstract: A therapeutic apparatus (900, 1000) comprising a high intensity focused ultrasound system (904) for heating a target zone (940, 1022). The therapeutic apparatus further comprises a magnetic resonance imaging system (902). The therapeutic apparatus further comprises a memory (952) containing machine executable instructions (980, 982, 984, 986, 988, 990) for execution by a processor (944). Execution of the instructions cause the processor to: generate (702, 802) heating commands (964) which cause the high intensity focused ultrasound system to sonicate the subject; repeatedly acquire (704, 804) magnetic resonance data (954) during execution of the heating commands; repeatedly calculate (706, 806) a spatially dependent parameter (970); and repeatedly modify (708, 808) the heating commands in accordance with the spatially dependent parameter such that within the target zone the spatially dependent parameter remains below a first predetermined threshold and above a second predetermined threshold.
