Problems solved by technology

[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 and other 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

Embodiment 1

[0072] Example 1 Fast and Accurate Registration of Brain Surgery Navigation

specific example

[0074]A 45-year-old male patient came to the doctor because of headache. MRI showed a left parasellar tumor with a diameter of 3 cm. Diagnosis: left parasellar meningioma. For accurate surgical positioning, ultrasound-MRI fusion imaging was performed. Before the MRI scan, the patient lies supine on the forehead and fixes the device of the present invention (the base of the device is a thin 3×4cm square with adhesive tape on one side, and a clip on each of the four corners of the non-adhesive side corresponding to the bayonet at the four corners of the lower end of the device body). MRI performs standard cross-sectional scans on the patient's head and the device of the present invention to obtain detailed intracranial images and detailed cross-sectional images of each geometric plane frame inside the device of the present invention. The next day, the patient's MRI DICOM image data was copied into the computer of the ultrasound fusion imaging system. In the electromagnetic fiel...

Embodiment 2

[0079] Example 2 Guidance of radiofrequency ablation of liver tumors under the background of liver cirrhosis

[0080] 1. Specific examples

[0081] The patient is a 50-year-old male with 20 years of hepatitis B and liver cirrhosis. Both routine ultrasound and CT revealed a solid space-occupying tumor in the right liver with a diameter of 2cm. Diagnosis: primary liver cancer of the right liver. Ultrasound-guided radiofrequency ablation was proposed. For accurate surgical positioning, ultrasound-CT fusion imaging was performed. Before the CT scan, the patient was placed supine in the liver area to fix the device of the present invention (the base of the device is a thin 3×4 cm square with adhesive tape on one side, and a clip on each of the four corners of the non-adhesive side corresponding to the bayonet at the four corners of the lower end of the device body). CT performs standard cross-sectional scans on the abdomen of the patient and the device of the present invention t...

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...
