1. CT (Computed Tomography), that is, electronic computer tomography, which uses precise collimated X-ray beams, gamma rays, ultrasonic waves, etc. to perform one-by-one cross-sectional scans around a certain part of the human body with a highly sensitive detector.
2. It has the characteristics of fast scanning time and clear image, and can be used for the inspection of various diseases; according to the different rays used, it can be divided into: X-ray CT (X-CT) and γ-ray CT (γ-CT), etc.

1. CT scan has greatly improved the diagnosis process of cancer and the detection of cancer stages
2. The highest resolution is 2μm, which achieves the perfect combination of compact device and micron resolution
3. Simple equipment maintenance and easy operation

Diagnosis of intracranial tumors, abscesses and granulomas, parasitic diseases, traumatic hematoma and brain injury, cerebral infarction and cerebral hemorrhage, intratumoral tumors and disc herniation is good, and the diagnosis is more reliable. Spiral CT scanning can obtain a finer and clearer blood vessel reconstruction image, that is, CTA, and can achieve three-dimensional real-time display, which is promising to replace conventional cerebral angiography.
