Conclusion

•Both are at 3.5 LP/MM.

Spatial Resolution

•iRay Venu 1717M has better contrast resolution resulted from higher S/N ratio. Thus less XRAY dosage is required for similar result.

Contrast Resolution

•Both detectors perform linearly. However, iRay Venu 1717M has better dynamic range, which results better performance on thicker and higher-density objects.
