The resolution of the image intensifier is limited by the resolution of the input-output fluorescent screen and the ability of the focusing electrode to maintain the image when the image is transferred from the input screen to the output screen. For an image intensifier whose input screen is CsI, its average resolution is 4-line pair/mm. The reasons for the decrease of resolution outside the image intensifier include: scattered radiation exists in the X-ray beam received by the input screen;Loss of sharpness due to movement of the patient and limited focal size.
In addition, the quality of fluorescence inspection image is also affected by the statistical fluctuation of the number of X-ray lines hit on the input screen.
The resolution, brightness and contrast of the image generated by the image intensifier are the maximum at the center of the image and gradually decrease towards the periphery.The brightness of the image along the periphery usually decreases by no more than 25 percent.
Newheek’s image intensifier is divided into six, nine and twelve inches depending on the diameter of the input screen. Its functional features can replace Toshiba, thales and philips and other brands.
Newheek image intensifier can meet your different purchasing needs.
