Example Embodiment

[0065] 1. Specific examples

[0066] A 45-year-old male patient presented with a headache. MRI: left parasella tumor, 3 cm in diameter. Diagnosis: left parasellar meningioma. In order to accurately locate the operation, ultrasound-MRI fusion imaging was performed. Before the MRI scan, the patient lies on the forehead and fixes the device of the present invention (the device base is a thin 3×4 cm square one-sided adhesive tape, and the four corners of the non-sticky side have a clip corresponding to the four lower corners of the device body). MRI performs a standard cross-sectional scan of the patient's head and the device of the present invention to obtain detailed intracranial images and detailed cross-sectional images of various geometric plane frames inside the device of the present invention. The next day, the patient's MRI DICOM image data was copied into the ultrasound fusion imaging system computer. In the electromagnetic field of the electromagnetic tracking system, an ...

[0071] Example 2 Radiofrequency ablation guidance of liver tumor in the background of liver cirrhosis

[0072] 1. Specific examples

[0073] The patient was a 50-year-old male with hepatitis B for 20 years and had liver cirrhosis. Both conventional ultrasound and CT revealed a solid tumor of the right liver with a diameter of 2 cm. Diagnosis: Primary liver cancer of the right liver. It is planned to use ultrasound-guided radiofrequency ablation. In order to accurately locate the operation, ultrasound-CT fusion imaging was performed. Before the CT scan, the patient lies in the liver area and fixes the device of the present invention (the device base is a thin 3×4 cm square adhesive tape with one side, and each corner of the non-sticky side has a clip corresponding to the bayonet at the bottom of the device body). CT scans the patient's abdomen and the device of the present invention in a standard cross-sectional scan to obtain detailed images of the liver and liver tumors and det...

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...
