CATH LAB SYSTEM FOR AIMING ULTRASOUND ENERGY

摘要

Methods and devices are presented which enable to determine the location in a body of an area of interest using a visualization modality, and then position and aim a treatment tool with respect to that area of interest without using that visualization modality. An intermediate object such as a mattress comprises a set of spaced dimensional markings visible under the modality and a set of markings (the same markings or other markings) which are optically visible to a user. Positions are determined with respect to the first set of markings, then the optically visible markings may be used to position and aim the treatment tool. Some embodiments are useful for HIFU treatment following catheterization guided by fluoroscopic monitoring.
