HistoSonics is developing a non-invasive, autonomous robotic platform capable of destroying tissue at a sub-cellular level with a novel beam therapy and new medical procedure called Robotically Assisted Sonic Therapy (RAST)?. RAST is based on the science of histotripsy, a non-invasive, non-thermal and non-ionizing radiation modality developed at the University of Michigan that uses the pressure created by focused sound energy to completely ablate or destroy tissue at a sub-cellular level.
