| titleOfInvention | Estimator for modulation transfer function of x-ray image detector according to "sharp edge" method |
| abstract | FIELD: medical equipment. n SUBSTANCE: estimator for modulation transfer function of X-ray image detector according to "sharp edge" method lies in application of tungsten plate with rectilinear sharp edge, fixed on substrate surface designed as lead plate by plates symmetry axis and so that substrate edge coincides with rectilinear sharp edge of tungsten plate. On substrate side opposite to sharp edge of tungsten plate there are two dot marks equally spaced from symmetry axis. Another two marks as line segment are mapped on substrate surface on tungsten plate side, each mark is angles to line of rectilinear sharp edge forming right angle if crossing virtual line which is actually extension of mark as line segment and line connecting dot mark with centre of rectilinear sharp edge of tungsten plate. n EFFECT: invention application enables to improve quality of measurements while modulation transfer function X-ray image detectors is estimated. n 3 dwg |
