The QUART dent/digitest 3.1 uses a design that's made to where the sensor can be removed after a test. The universal design is made to keep the sensor under control while the line pair is made to handle a 45 degree angle. The 6 mm aluminum filtration is also made to work right with slots for a digital storage screen. A digital sensor is also added with low-contrast test subjects in mind and a strong centering aid to make it work. This also uses many parameters to test like an x-ray field, image receiver, visual spatial resolution level and low contrast setting.
