“…A notable advantage of this system is the use of active tracking coils for the accurate task-space placement of the HIFU system. MR-tracking coils are small, radio-frequency coils that can be integrated with interventional devices for high-resolution localization in MRI [ 99 , 100 , 101 , 102 ]. Li et al designed two custom coils to obtain ablator position and orientation with a root mean square (RMS) error of less than 1.1 mm and orientation RMS errors of less than 2.3°.…”

This paper provides an overview of current robot-assisted high-intensity focused ultrasound (HIFU) systems for image-guided therapies. HIFU is a minimally invasive technique that relies on the thermo-mechanical effects of focused ultrasound waves to perform clinical treatments, such as tumor ablation, mild hyperthermia adjuvant to radiation or chemotherapy, vein occlusion, and many others. HIFU is typically performed under ultrasound (USgHIFU) or magnetic resonance imaging guidance (MRgHIFU), which provide intra-operative monitoring of treatment outcomes. Robot-assisted HIFU probe manipulation provides precise HIFU focal control to avoid damage to surrounding sensitive anatomy, such as blood vessels, nerve bundles, or adjacent organs. These clinical and technical benefits have promoted the rapid adoption of robot-assisted HIFU in the past several decades. This paper aims to present the recent developments of robot-assisted HIFU by summarizing the key features and clinical applications of each system. The paper concludes with a comparison and discussion of future perspectives on robot-assisted HIFU.
