Role Of Digital Encoders In Medical Imaging

Digital encoders, such as linear encoders, rotary encoders, optical encoders, and more, are used in medical imaging technology such as computed tomography scanners (CT) and magnetic resonance imaging (MRI). In this blog, Walker Machinery, distributor of encoders and DRO systems in Milton, Ontario, explores the role of encoders in these medical imaging devices in detail.

How Digital Encoders Serve CT Scanners?

Gantry Rotation

Gantry is the main circular disc that contains the tomography scanners. Magnetic encoders are used to ensure high-precision movement feedback at high speeds. This helps the gantry to move in a smooth and controlled manner.

Table Positioning

The table on which the patient is strapped uses some form of absolute encoders to make slight adjustments to its movement so that the imaging and scanning are optimized.

Collimators

Collimators are metallic devices that direct and reduce the intensity of X-ray beams on a CT scan. Digital encoders are also used here to control the position and shape of the X-ray beams.

How Digital Encoders Serve MRI Machines?

Scanner Positioning

In MRI machines, digital encoders are used to position the patient bed so that it is placed precisely beneath the scanner bore. 

Data Acquisition

Encoders also aid in comprehensive data acquisition and storage in advanced radiotherapy. Digital encoders, in this case, are used to compress large amounts of visual data for effective storage and examination at a later date. 

Conclusion

To conclude, digital encoders are used in both CT scanners and MRI machines for ensuring precise machine movement, fine tuning patient bed for better scanning and other high-accuracy purposes.
