| When disconnecting the endoscope | 1.Empty water out of the scope before laying it down 2.Disconnect water bottle – hold end up when initially disconnect to stop leaks. 3.Wipe outside of scope to get rid of gross debris 4.Disconnect light guide and electronics |
| Milliamperage | refers to the current flowing through the X-ray tube. The flow of electricity is measured in amperes (A) and is often referred to as amps. |
| mA | Determines the intensity of the X-ray beam (the quantity of photons released per second in the primary beam.) |
| Exposure Time Equation | current flowing (mA) x Exposure time (s) = amount of x-ray photons produced (mAs) |
| Grid Factor | The amount of radiation that hits the grid, in relation to the amount that passes through the grid and into the tissues . |
| Calculate new mass using grid factor | New mAs = old mAs x grid factor |
| Film focal distance (FFD) | the distance between the focal spot and the x-ray film. |
| Inverse square law | The effect of altering the FFD is called the Inverse Square Law |
| Calculate new mass using FFD | New mAs = Old mAs x New FFD(Squared) / Old FFD(Squared) |
| Plaster of Paris (POP) calculations | Wet Plaster of Paris = mAs x 4 Dry Plaster of Paris = mAs x 2 |
