This device, the development of which has been led by the medical physics team at Leeds Teaching Hospitals NHS Trust, allows routine QA of dental panoramic x-ray units.

Overview:

This device, the development of which has been led by the medical physics team at Leeds Teaching Hospitals NHS Trust, allows routine QA of dental panoramic x-ray units.

The Problem:

Routine QA of dental panoramic x-ray units is severely limited because of the complexity of the device and therefore it is not possible to fully determine whether the equipment is correctly set up or out of tolerance. Existing devices on the market are complex to use, machine specific and costly.

The Solution:

This device, which is light and easy to use, will allow dental surgeries and hospitals to routinely calibrate their x-ray units and hence circumvent the cost of using external contractors.

More frequent calibration is likely to reduce the numbers of x-rays a patient may have to undergo.

Technical Information:

Based on a standard jaw the device is mounted on a tripod which allows repeatable anatomic positioning in any panoramic machine including chin, bite and forehead positioning.

All these measurements obtained in just three films. Combined with a remote solid state detector kV/dose meter, the device allows a full QA survey to be conducted on panoramic x-ray units that usually have minimal testing.
