A focused ultrasound ('FUS'} system capable of use in a small bore imaging system, such as a small bore magnetic resonance imaging ('MRI'} system is provided. The FUS system generally includes an ultrasound transducer whose position is adjusted by a positioning system. The positioning system is sized to fit within the bore of the small bore imaging system. For instance, the positioning system can fit within a diameter of 150 millimeters or less.

Focused ultrasound system for small bore imaging

A focused ultrasound system includes an ultrasound transducer configured to emit focused ultrasound energy toward a subject and a positioning system configured to position the ultrasound transducer to localize the focused ultrasound energy within a target location. The positioning system includes a drive apparatus to translate the ultrasound transducer along at least one axis of motion and a motor controller to control the drive apparatus. The focused ultrasound system also includes a control system connected to the motor controller that is programmed to receive imaging/location data from an imaging system, determine positional coordinates of the target location based on the imaging/location data, and register the positional coordinates of the target location with the positioning system. The positional coordinates are sent to the motor controller via an input signal to cause the motor controller to control the drive apparatus so as to translate the ultrasound transducer.
