Abstract

The invention discloses an ablation area determination method and device based on a medical image and a storage medium, and belongs to the technical field of image processing. The method comprises the following steps: acquiring a preoperative image before ablation of focus tissue in a target area and a postoperative image after ablation; performing registration and three-dimensional modeling on the preoperative image and the postoperative image to obtain a three-dimensional preoperative image and a three-dimensional postoperative image; based on the voxel difference value of each voxel on the three-dimensional preoperative image and the three-dimensional postoperative image, performing regional aggregation on each voxel to obtain at least one aggregation region; displaying the aggregation area on a display interface so that an operator can determine whether the aggregation area is an ablation area or not; under the condition that the operator determines that the aggregation area is an ablation area, displaying the ablation area according to a preset display mode; the problem that the recognition result is possibly inaccurate when a machine recognizes the ablation area can be solved; the accuracy of ablation area identification can be improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a method, device and storage medium for determining an ablation region based on medical images. Background technique [0002] Thermal ablation (Thermal Ablation Therapy) is a technology that uses thermal effects to cause coagulation, necrosis, or vaporization and carbonization of diseased tissues to achieve the purpose of ablation and inactivation therapy. Thermal ablation includes laser, high-frequency electric knife, argon plasma coagulation, microwave therapy, radiofrequency therapy, etc. Taking Laser Interstitial Thermal Therapy (LITT for short) technology in thermal ablation as an example, LITT is a new type of minimally invasive technology for a variety of intracranial lesions, and has been used to treat deep intracranial, relatively Intracranial lesions that are difficult to remove, such as tumors, radiation necrosis, epileptic lesions in th...
