Abstract

The invention relates to a method for synthesizing an electrical impedance tomography (EIT) functional image and an anatomical image. The method comprises the following steps: (1) acquiring the EIT functional image and the anatomical image at the same time; (2) performing boundary registration on the EIT functional image and the anatomical image; (3) extracting the image characteristics of an electrical impedance sensitive area in the EIT functional image; and (4) performing image synthesis of the EIT functional image and the anatomical image by an image segmentation method to obtain a synthesis image of pseudo color display. The invention synthesizes the EIT functional image and the anatomical image to generate the pseudo color display image, solves the problem of effective synthesis of the EIT functional image information and the clinical anatomical image information, provides more sufficient and comprehensive anatomical and functional image information for clinical diagnosis and treatment and has the characteristics of simple processing method, high performance, easy implementation and the like.

Description

technical field [0001] The invention belongs to the technical field of biomedical imaging, in particular to a method for synthesizing electrical impedance tomography functional images and anatomical images. Background technique [0002] Medical imaging has become an indispensable part of the modern medical field. Its application runs through the entire clinical work. It is not only widely used in disease diagnosis, but also plays an important role in the planning design, program implementation and efficacy evaluation of surgical operations and radiotherapy. . At present, medical images are divided into two parts: anatomical images and functional images. Anatomical images mainly describe the morphological information of the human body, including X-ray transmission imaging, CT, MRI, US, and sequence images obtained by various endoscopes (such as laparoscopes and laryngoscopes); functional images mainly describe human metabolic information, including PET, SPECT, fMRI, etc. E...
