Early tumor positioning and tracking method based on multi-mold sensitivity intensifying and imaging fusion

Abstract

An early stage tumor localizing tracking based on the multimode sensitization imaging fuse, belongs to the medical image processing field. The invention includes: a medical image before the operation for obtaining the tumour aim focus imaging sensitization; an ultrasound sensitization image during the operation for obtaining the tumour aim focus imaging sensitization. When the image is processed the guide therapy, using the global rigid transformation and the local nonstiff transformation combination round the tumour aim focus as the geometric transformation model with deformation registration, the sensitization images before and during the operation are processed with the deformation registration based on the union marked region, while the images before and during the operation are fused, to rebuild the three-dimensional visualization model in the tumor focus region. Using the above deformation registration method to complete the sport deformation compensation for the imaged before the operation, the target tracking of the tumour target focus is further automatically completed. The invention can be used in a plurality of places, such as the early diagnosis of the tumour, the image guide tumour early intervention, the image guide minimal invasive operation, the image guide physiotherapy etc.

Description

technical field [0001] The invention relates to a method in the technical field of medical image processing, in particular to an early tumor location tracking method based on multi-mode sensitization imaging fusion. Background technique [0002] Image-guided minimally invasive interventional therapy is the product of the interdisciplinary development of modern biomedical engineering, biophysics, biochemistry, modern information processing, microelectronics technology, molecular medicine and clinical medicine, and represents the inevitable development direction of clinical disease treatment technology. The fundamental purpose of image-guided therapy is to use preoperative or intraoperative medical images to guide the targeted treatment of target lesions, and help doctors understand the shape, structure and relationship between target lesions and their surrounding tissues during treatment. Accurate tracking and positioning of tumor lesions is the core issue of image-guided the...

However, this patent does not mention the use of multiple modes of contrast agents for preoperative and intraoperative imaging targeted sensitization of tumor target lesions. During the treatment of tumor target lesions, it does not consider significant areas of interest based on tumor target lesions.
