Noninvasive standard registration device applicable to fusion imaging in ultrasonography, CT (computed tomography), MRI (magnetic resonance imaging), PET (positron emission tomography) and the like

Abstract

The invention provides a noninvasive standard registration device applicable to fusion imaging in ultrasonography, CT (computed tomography), MRI (magnetic resonance imaging), PET (positron emission tomography) and the like. The noninvasive standard registration device comprises a carrier bag, a body surface fixator and at least one frame in geometric plane shapes. The carrier bag is rectangular and is fully filled with liquid. The geometric plane shaped frame is disposed in the carrier bag and is constantly perpendicular to the horizontal plane. Spacing more than 0.1cm is reserved between the geometric plane shaped frame and the inner wall of the carrier bag. By the noninvasive standard registration device, the geometric plane shaped frame in the ultrasonic images can be kept in the same standard cross-section direction as the corresponding geometric plane shaped frames in CT, MRI or other imaging methods, and non-regularity of universality and cross section of an ultrasonic probe are controlled. The speed in fusion registration of ultrasonography, CT, MRI or PET images can be greatly increased by using the noninvasive standard registration device while precision registration is guaranteed, and the noninvasive standard registration device is widely applicable and has broad application prospect.

Description

technical field [0001] The invention relates to a non-invasive standard registration device which facilitates image fusion development and clinical application of ultrasound and CT images, nuclear magnetic resonance images or PET images. Background technique [0002] 1. Introduction to Image Fusion Technology [0003] Medical image fusion technology is a hot topic in research at home and abroad. Medical imaging includes X-ray, ultrasound, computed tomography (CT), magnetic resonance (MRI), single photon emission tomography (SPECT), positron emission tomography (PET), infrared, digital subtraction (DSA), fluorescence contrast, etc. . Medical images of various modalities reflect human body information from different angles, and comprehensive diagnostic information cannot be obtained from a certain image alone. If a variety of images only rely on the doctor's spatial conception and speculation to comprehensively determine the information they want, the accuracy will be affec...

[0010] 3. Technical Dilemma of Ultrasound Image Fusion and Registration

[0013] 1) The ultrasound image is not a standard cross-sectional view, and its image is universal with any change in the direction of the probe in the operator's hand;

[0014] 2) Ultrasound images lack standardization compared with CT, MRI, etc. cross-sectional standard sections;

As mentioned above, due to the lack of standard cross-sections of ultrasound images and the narrowness of ultrasound sections, the registration between ultrasound and standard sections such as CT or MRI is more difficult and time-consuming
