Koworase X is a specialized system for removing burn-in effects on Computed Radiography (CR) image plates. It restores image quality and sensitivity without damaging the plate and meets the requirements of the ASTM E2445 standard. The system uses a two-phase process that combines UV-C exposure and powerful LED light to eliminate deep image artifacts.

How does it work?

The deletion takes place in two steps:

• First, the plate is exposed to intense UV-C illumination (254 nm) which saturates the phosphor layer.

• Then, white, red and green LED lights are activated, removing any remaining burn-in and reducing the background level to a minimum.

The result is a completely clean plate with a maximum grayscale difference of 0.5%, which is better than the standard requirement of 1%. The sensitivity and life of the plate are not affected.

Important features

• Active erase size up to 490 × 370 mm

• Erasing time of 3–6 minutes, depending on disc wear

• Operating voltage 90–260 V and power consumption of approximately 90 W

• Robust steel construction with pull-out drawer for easy handling

• Possibility of additional feeding table for long plates

Benefits

• Fast and effective removal of image artifacts

• Maintains image quality according to ASTM standards

• Gentle process that does not reduce the sensitivity of the plate

• Compatible with all common CR plate manufacturers

• Ideal for industrial X-ray inspection and workshop use
