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

[0064] Example 1 Rapid and Accurate Registration of Brain Surgery Navigation

specific example

[0066] 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 fie...

Embodiment 2

[0071] Example 2 Guidance of radiofrequency ablation of liver tumors under the background of liver cirrhosis

[0072] 1. Specific examples

[0073]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 to...

Abstract

The invention provides a non-invasive standard configuration device suitable for ultrasound-computed tomography (CT) / magnetic resonance imaging (MRI) / position emission tomography (PET) and other fusion imaging. The non-invasive standard configuration device can enable plane geometry frame diagrams in ultrasound images and corresponding plane geometry frame diagrams in CT or nuclear magnetism or other imaging to have the same standard cross section direction, and controls universal performance of an ultrasonic probe and non-standard of sections. By means of the non-invasive standard configuration device and on the basis of accurate configuration, fusion configuration speed between ultrasound and the CT, the nuclear magnetic resonance or the PET is improved remarkably, and the non-invasive standard configuration device is wide in application range and has good 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...
