What kind of technology is CT-guided needle biopsy?
Feb 14, 2022
Some lesions are most clearly displayed after CT imaging, and cannot be replaced by ultrasound and MRI. For such lesions, CT-guided biopsy is the clearest observation and the most accurate method for puncturing. Since CT-guided biopsy requires percutaneous puncture into the lesion layer by layer, the distance traveled is long, so the technical requirements are very high. The front end of the slender puncture needle cannot be equipped with a camera, and the doctor cannot see the real tissues and organs during the operation, and can only recombine the tomographic images in the brain through the CT images taken before and during the operation. The positional relationship with the virtual stereoscopic imaging can adjust the puncture depth and angle in real time and quickly until it hits the target.
