I currently have a fault on one of my mobileDaRt. The image quality is not clear enough for the user, it has a speckled effect with concentric lines radiating from the centre of the subject on the image.I have changed the sensor with a known working one and replaced the sensor cables. I have checked the output,and also carried out the calibration procedures as per the manual.
I am new to this piece of equipment and Digital Xray in general and would appreciate any advice with this problem.
