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. In particular, provided herein are optimized systems and methods that provide targeted, efficacious histotripsy in a variety of different regions and under a variety of different conditions without causing undesired tissue damage to intervening/non-target tissues or structures.

Histotripsy systems and methods

A system and method, including an ultrasound imaging transducer, an ultrasound therapy transducer, a robotic arm configured to orient the ultrasound imaging transducer and the ultrasound therapy transducer about a patient, a display connected to imaging transducer, and a memory, storing instructions that when executed by a processor receive ultrasound images from the imaging transducer, present ultrasound images, receive an input to alter a shape of a contour line, present the contour line, receive an input of a size of a margin around the treatment area, present the margin, determine end points at locations where X, Y, and Z axes bisect the contour line in an XZ plane and a YZ plane, drive the ultrasound therapy transducer to a location where a focal point of the ultrasound therapy transducer is at the end point, and determining whether a resistance to movement exceeds a threshold.

A Histotripsy therapy system is provided that can include any number of features. In some embodiments, the system includes a high voltage power supply, a pulse generator electrically coupled to at least one signal switching amplifier, at least one matching network electrically coupled to the signal switching amplifier(s), and an ultrasound transducer having at least one transducer element. The Histotripsy therapy system can further include an ultrasound Doppler imaging system. The Doppler imaging system and the Histotripsy therapy system can be synchronized to enable color Doppler acquisition of the fractionation of tissue during Histotripsy therapy. Methods of use are also described.
