ABLATION TREATMENT PLANNING AND DEVICE Russian patent published in 2016 - IPC A61B90/10 G06T11/80 G06Q50/00 

FIELD: medicine.

SUBSTANCE: method for ablation treatment planning involves receiving a data collection referred to three-dimensional images of the area of interest (I); introducing a 3D ablation volume (AV) model data into the received collection I; drawing a two-dimensional image containing the MPR cross section of the area of interest and the AV in the MPR plane. This plane is used as a secant; an AV outside is the first to be rejected so that an AV inside is only marked throughout the MPR plane in a stencil buffer. The AV inside is the second to be rejected so that the AV outside is imaged throughout the MPR plane in the stencil buffer. The pixels making a part of the AV inside and marked first are rejected before blending in a colour buffer. An ablation treatment planning device comprises a unit for receiving the data collection I; an unit for introducing the 3D AV model data into the received collection I and an unit for drawing the two-dimensional image containing the MPR cross section of the area of interest and the AV in a MPR plane to be used as a secant. A machine-readable carrier comprises software for implementing the above method. Using the described graphical approach, any arbitrary-shaped AV can be imaged in a three-dimensional space by drawing two-dimensional images in the desired MPR plane.

EFFECT: providing the accurate control of the AV, optimising the position and direction of an ablation needle during the following therapeutic procedures.
