6.6 Ensuring Image Quality
The following HyperLight-G features contribute to high image quality:
• DC voltage X-ray generation is efficient in delivering energy at the level
optimized for diagnostics, with shorter exposure times required.
• The smaller the focal spot, the better the resolution. The HyperLight-G has a
small 0.7mm focal spot.
As with the suspended tubehead of a conventional wall-mounted X-ray
system, some motion of the tubehead during actual exposures is possible.
Use both hands to hold the HyperLight-G during the exposure and keep
steady. The pistol-grip style is ideal for keeping hands behind the backscatter
shield, positioning and aiming (with line of sight through the clear shield) so
as to achieve a quality image and avoid cone-cutting or retakes.
Image degradation or blurriness does not result due to motion of the
handheld X-ray source.
