The phantom for evaluation of imaging performance of fluoroscopic systems. It allows brightness and contrast adjustments, circular geometry check (scanning linearity) plus wide-range low-contrast and high-contrast resolution evaluation.
The phantom for evaluation of imaging performance of radiographic systems. It allows wide-range low-contrast and high-contrast resolution evaluation and sensitometric measurements.
With Pro-Star test Patterns focal spot size can be determined by observing the regions of blurring which occur when the pattern is radiographed by an x-ray source of finite dimensions.
