The Dental Image Quality Test Tool was designed to provide a means of testing the functionality of dental x-ray units.
The Dental Image Quality Test Tool consists of a phantom cradle that holds the evaluation phantom. The cradle has
built-in slots for attenuation material. It also has an exposure chamber holder, a dental fog test tool and a mounting
screw for connection to a tripod.
The Evaluation Phantom consists of four different copper wire mesh that have the following ratios: 100, 120, 150, and
200 lines per inch. It has four steps for contrast and density measurements. There is also a slot to fit intra-oral films.
The Dental Image Quality Test Tool comes with a Dental Fog Test Tool, which is designed for evaluating darkroom
