Here are some of the tools we use to minimize your exposure during your X-rays:

Thyroid Collar -   The National Council of Radiographic Protection requires thyroid shielding for all children and they highly recommend it for all adults. Studies show that the use of thyroid collars can reduce exposure levels by over 30%. (1)

Aiming Devices -   State-of-the-art XCP (Extension Cone Paralleling) aiming devices ensure accurate and reproducible x-rays every time, thereby reducing the need for retakes. (2)

Faster Film Speed and Digital Sensors -   Increasing the film speed or using digital radiography contributes to reducing exposure. F speed film requires 20% to 50% less exposure time than E or D speed film, respectively. (4) When digital images are made the dose reduction ranges from 0% to 50% of the exposure required for F speed film. (5)
