Optimizing High-Precision Motion Control for CT Scanners
A CT scanner is an essential diagnostic tool in modern medicine, allowing for detailed cross-sectional images of the human body. High-precision motion control for CT scanners is an absolute must. By rotating X-ray projections 360 degrees, CT scanners capture high-resolution images to help doctors diagnose and treat various conditions.
To ensure smooth operation, imaging precision, and patient comfort, these scanners rely on advanced servo motors for precise motion control.
The Role of Servo Motors in CT Scanners
Servo motors are integral to the function of CT scanners, facilitating:
- Gantry Rotation – The motor drives the gantry, rotating it around the patient for accurate imaging.
- Bed Movement – Vertical and horizontal bed adjustments allow precise positioning for optimal scans.
- Low Noise & Vibration – Essential for clear imaging and improved patient experience.
