| Question | Answer |
| After the plate is scanned by the reader uniy, it is exposed to an intense _________ to erase the exposure. | White light. |
| P.A.C.S networks consist of _________, ________, and _________. | Computers. Servers. Archives. |
| What does P.A.C.S stand for? | picture archival and communication systems. |
| What is PSP? | Photostimulable phospor. |
| How many times can a PSP plate be used? | 10,000 times. |
| How can density be indicated? | By the number that corrlates to the amount of exposure. |
| What does the C.R system equiptment include? | A reader for image processing. |
| What is PSP made up of? | Barium Fluorphalide with europium. |
| What is used th scan the plate in the CR reader? | A laser beam. |
| What is Post-processing? | Any change made to the image after the esposure is taken. |
| Where is Digital Imaging produced, prossesed, viewed, and stored? | On a computer. |
| What are the two types of Digital Imaging? | Computed Radiography. Digital radiography. |
| The C.R reader scans the imaging plate to release stored data in what form? | Visable light. |
| why is Digital radiography reffered to as "Cassette-less"? | Because the detector is incorpurated into the x-ray table or up-right wall unit. |
| What is In-direct conversion in digital radiography equiptment? | Data acquisition in which x-ray energy is converted to light and then to an electric signal. |
| What is Direct conversion in digital radiography equiptment? | The x-ray energy is converted directly into an electric signal. |
| What divice glows when hit by an high energy x-ray photon? | The Scintillator. |
| What is the Scintillator made of? | Cesium iodine. |
| The D.R systems use___________, and __________. | Silicon-charged coupled divices.(CCDs) Photostimulable phospor plates. (PSP) |
| Why should technique charts be used even though the computer gives the ability to manipulate the density and contrast of the image? | To avoid unnecessary exposure for the patient. |
| What limits the field of radiation to the subject being x-rayed? | Collimation. |
| What can inadequate collimation result in? | Inapproprite contrast. |
| How long does it take an exposed I.R to start loseing its image after being opened to light? | 15 seconds. |
| What are the D.R technial considerations? | Kilovoltage, part centering, number of exposures, cassette integrity, and collimation. |
