Abstract
A histotripsy therapy system configured for the treatment of tissue is provided, which may include any number of features. Provided herein are systems and methods that provide efficacious non-invasive and minimally invasive therapeutic, diagnostic and research procedures. The systems and methods herein are configured to measure and display forces acting upon the therapy treatment head during a procedure. In some aspects, buoyancy forces from the acoustic coupling medium are also accounted for.
Claims22
A method of monitoring forces against an ultrasound treatment head, comprising:
- submerging at least a portion of the ultrasound treatment head in a fluid reservoir filled with an acoustic coupling medium;
- determining raw forces acting against the ultrasound treatment head;
- determining a pose angle of the ultrasound treatment head within the acoustic coupling medium;
- determining an insertion depth of the ultrasound treatment head within the acoustic coupling medium;
- determining buoyancy forces applied by the acoustic coupling medium against the treatment head for the determined pose angle and insertion depth of the ultrasound treatment head;
- determining clinically relevant forces acting against the ultrasound treatment head by subtracting the buoyancy forces from the raw forces;
- and
- adjusting ultrasound treatment head movement in response to clinically relevant forces that exceed at least one safety threshold.
