Embodiment Construction

[0031] figure 1 A thermal ablation therapy system is shown schematically and exemplarily, comprising a thermal ablation device 1 and a system as a subsystem for assisting a user in properly positioning the thermal ablation device 1 in a treatment area of ​​a patient's body. By using this thermal ablation therapy system, thermal ablation can be performed in the patient's body 2 in order to treat target tissue in the patient's body 2 . Target tissues may specifically include tumors.

[0032] The thermal ablation device 1 may be configured for hyperthermic tumor ablation, ie it may be configured to apply energy to tissue (in particular tumors) in order to heat the tissue to kill cells (in particular cancer cells). For example, energy may be provided by means of radio frequency (RF) current (this method is also called RF ablation), or energy may be provided by means of microwave radiation or ultrasound emitted by the thermal ablation device 1 . In RF ablation, an electric curren...

Abstract

The invention relates to a system for assisting a user in positioning a thermal ablation device (1) on the basis of a planned ablation position. The system comprises an evaluation unit (6) adapted to(i) compute an optimized thermal dose distribution deliverable to the treatment region by means of the device (1) operating at a current position thereof, (ii) determine a path for steering the device(1) from the current position to the planned position and to assign a cost to the determined path, the cost quantifying estimated detrimental effects of steering the device (1) along the computed path, and (iii) present information about the optimized thermal dose distribution and about the cost assigned to the computed path to the user.

Description

technical field [0001] The present invention relates to thermal ablation therapy particularly for the treatment of cancer. More particularly, the present invention relates to systems and methods for assisting in the positioning of thermal ablation devices. Background technique [0002] In thermal ablation therapy, extremes of high or low temperature are locally applied to tumors to induce cellular damage and ultimately tumor cell apoptosis and coagulation necrosis in cancer cells. In order to apply such temperatures, miniaturized ablation probes can be introduced into the patient and directed to the treatment area including the tumor by means of minimally invasive interventions. To apply high temperatures, ablation probes may deliver microwave radiation or ultrasound to the tissue. To apply low temperatures, the ablation probe may be configured as a cryoprobe through which a refrigerant flows to cool tissue surrounding the cryoprobe. [0003] The thermal ablation therapy ...
