|---|---|---|---|---|---|
| Air gap | show 🗑
|
||||
| Back scatter | show 🗑
|
||||
| show | interaction takes place at relatively low energy levels (below 10 keV). When the incoming photon is absorbed by the atom, the becomes excited, the excited atom produces a new x-ray photon but in a new direction and has the same energy and wavelength.
🗑
|
||||
| show | Incoming x-ray photon interacts with an outer shell electron of an atom ejecting it from the atom and then proceeds in a different direction. The majority of the photon’s energy is converted into a new photon and has less energy and longer wavelength
🗑
|
||||
| show | a composite of two grid s with the lead strips at right angle to each other
🗑
|
||||
| show | the range of distance with in which the grid will not absorb an undue amount of useful radiation
🗑
|
||||
| show | lead strips are aligned to the direction of the diverging primary x-ray beam, is precisely aligned to the to the x-ray beam at specific SID
🗑
|
||||
| show | a device placed between the patient and the IR to reduce radiation fog; consists of closely placed lead strips aligned side by side
🗑
|
||||
| show | technique chart in which the mAs is constant and kVp changes per patient size
🗑
|
||||
| Grid cutoff | show 🗑
|
||||
| show | the number of lead strips per inch
🗑
|
||||
| show | the effectiveness of a grid, the relationship between the height of the lead strip to the width of the inner space material
🗑
|
||||
| Parallel grid | show 🗑
|
||||
| Photoelectric effect | show 🗑
|
||||
| Characteristic photon | show 🗑
|
||||
| show | radiation produced by the photoelectric effect
🗑
|
||||
| Stationary grid | show 🗑
|
||||
| Technique chart | show 🗑
|
||||
| Compensating filter | show 🗑
|
||||
| show | a technique chart where the kVp remains the same (optimum range) and the mAs varies
🗑
|
||||
| Coned-down image | show 🗑
|
||||
| show | a special cassette with a grid built into the front side; typically have lower ratios than the grid
🗑
|
||||
| Grid lines | show 🗑
|
||||
| show | the SID in which the primary beam is precisely aligned to the x-ray beam
🗑
|
||||
| show | radiation hits an object (atom) and changes direction
🗑
|
||||
| show | tool used for body part measurement usually in cm
🗑
|
||||
| Optimum kVp | show 🗑
|
||||
| show | a human skeleton or portion of a skeleton, encased in a plastic material that is similar in density to human tissue
🗑
|
||||
| Bucky | show 🗑
|
||||
| show | the moving grid inside of the x-ray table that prevents grid lines/ is interchanged with the bucky.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
