Embodiment Construction

[0042]The present invention provides systems and methods for real-time tracking of the motion of a subject of interest (eg, a treatment target) during an image-guided procedure. For example, the procedure may involve applying focused ultrasound to (i.e., sonicating) a material, tissue, or organ for heating it, thereby necrosizing, ablating, or otherwise destroying the tissue (e.g., if it is cancerous), or using for non-destructive treatments such as pain relief or controlled induction of hyperthermia. Ultrasound can also be used for other non-thermotherapy types of therapy such as, for example, neuromodulation. Alternatively, the procedure may use different forms of therapeutic energy, such as, for example, radio frequency (RF) radiation, X-rays or gamma rays, or charged particles, or involve other therapeutic modalities, such as cryoablation. Motion tracking in various therapeutic procedures can be used to direct a beam of therapeutic energy onto a target and / or around other...

Abstract

During a focused-ultrasound or other non-invasive treatment procedure, the motion of the treatment target or other object(s) of interest can be tracked in real time based on (i) the comparison of treatment images against a reference library of images that have been acquired prior to treatment for the anticipated range of motion and have been processed to identify the location of the target or other object(s) therein and (ii) complementary information associated with the stage of the target motion during treatment.

Description

technical field [0001] The present invention relates generally to tracking moving tissue or organs, and more particularly to tracking their motion during non-invasive treatments. Background technique [0002] Tissue, such as benign or malignant tumors or blood clots within a patient's skull or other body region, can be treated invasively by surgically removing the tissue or non-invasively by using, for example, thermal ablation. Both methods are effective in treating certain localized conditions in the body, but involve delicate procedures to avoid destroying or damaging otherwise healthy tissue. Surgery may not be appropriate for cases where diseased tissue is integrated within healthy tissue, unless healthy tissue can be spared or its destruction is unlikely to adversely affect physiological function. [0003] Thermal ablation, which can be achieved using focused ultrasound, is particularly attractive for treating diseased tissue surrounded by or adjacent to healthy tissu...
