Other factors that can help in minimizing radiation exposure include using proper exposure techniques from a professionally developed technique chart, sedation for patients that are in pain or anxious, and positioning aids. Lateral view of the skull with details of the teeth. Although we have advanced in many other ways, the production of x-rays remains the same as when they were first discovered: accelerated electrons interact with a metal target on the anode in the x-ray tube head, heating the target and causing photons to be produced. Lateral and ventrodorsal Quick Tips 1. It is the responsibility of the practice and the team members to be aware of and follow state regulations on physical and manual restraint.
