A radiology department’s routine protocol is to complete knee exams with the use of a grid. However, in a portable situation, the technologist does not have a grid and decides to complete the exam without a grid and without making any changes to the technique. How will the image quality change without the use of the grid?

For a lateral lumbar spine, placing a lead shield on the table behind the area of exposure:

The distance from the object being radiographed to the image receptor is demonstrated on the above image by the letter:

If the original radiograph has a good IR exposure and the kVp is increased, which of these statements is true?1) Receptor exposure increases2) Contrast increases3) Receptor exposure decreases4) Contrast decreases5) Receptor exposure stays the same6) Contrast stays the same

An exposure is taken using a wedge filter. Which area of the image receptor will recieve the least exposure?

X-rays damage biological matter by the process of:

Which of the following factors need to be considered when determining the grid to be used for a specific examination?

If the radiograph has been taken using beam position 1, which part would be more spatially distorted?

What is the ratio of a grid that has a grid strip thickness of 4 mm, a grid interspace thickness of 20 mm and a height of 160 mm?

In order to select a grid with the proper ratio, which of the following factors should be considered?1)  Positioning latitude2)  Degree of cleanup3)  Kilovoltage range
