Problems solved by technology

However, in some cases, irreversible damage may have been done after excessive energy was absorbed by non-target tissues
Furthermore, any adjustments to the sonication program based on the measured effects during treatment lead to an increase in the overall treatment time which may not only consume the patient's patience but also introduce errors eg due to inadvertent but unavoidable patient movement

Embodiment Construction

[0024] Various embodiments of the invention provide methods for planning focused ultrasound treatment of one or more target tissues within a tissue region, which may also include non-target tissues. Treatment planning typically has the dual goal of achieving a desired therapeutic effect in target tissue while avoiding damage to non-target tissue. figure 1 An exemplary treatment planning method according to various embodiments is shown in flowchart form. As shown, treatment planning may begin in step 100 by providing a visual representation of the patient's anatomy within an area of ​​interest to the treating physician. The visual representation may, for example, comprise or consist of a series of image slices acquired with MRI, computed tomography (CT), ultrasound or any other medical imaging modality, or of a three-dimensional graphical model created based on these images. In step 102, the physician identifies a target or a portion of a target within a region of interest, f...

Abstract

A focused-ultrasound or other procedure for treating a target within a tissue region can be planned iteratively by creating a treatment plan specifying a treatment location pattern and stimuli applied thereto, simulating the treatment, computationally predicting an effect of the simulated treatment, comparing the predicted effect against one or more treatment constraints (such as efficacy and / or safety thresholds), and, if a constraint is violated, repeating the simulation for an adjusted treatment plan.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to US Provisional Patent Application No. 61 / 757,990, filed January 29, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to treatment planning for focused ultrasound procedures. More specifically, various embodiments relate to computing systems and methods for simulating and adjusting therapeutic procedures prior to execution. Background technique [0004] High-intensity focused ultrasound energy (ie, having a frequency greater than about 20 kilohertz) can be used therapeutically to treat internal tissue regions within a patient. For example, ultrasound can be used to induce coagulation and / or necrosis in target tissue regions such as tumors. During this procedure, ultrasound energy is absorbed by tissue, resulting in the generation of heat. The absorbed energy heats the tissue cells in the t...
