General Information


1.1 How to Use the Phantom

1. Place the EZ CR-DIN Phantom on the imaging surface of the x-ray table. (The standard is DIN

V 6868-58.)

2. Select the proper SID.

3. Install the CR Plate in the Bucky.

4. Select the technical factors in the generator; usually 10 mAs, and set the kVp at 72.

5. The initial use of the phantom will require the user to find the correct mAs and kVp that will be

used on each exposure.

6. After exposure of the phantom, take the CR Plate and select the anatomical region that will

allow you to see the six-step wedge (test objects). Typically, this will be the Abdomen
Processing, but may vary with manufacturer. No Image Processing or raw data can also be
used to visualize the region with no edge enhancement.

1.2 CR System to Print Film Only

If you are using a CR system to print film only, you will want to evaluate the film for the following:

1. You should be able to visualize the contrast step wedges, LP resolution phantom and the four

(4) linearity squares.

2. The line-pair number should be recorded and compared to future exposures.

3. Densities should be taken and recorded on the step wedges and linearity squares.

4. A density reading should also be taken in the free area and recorded.

Record the technical factors used in this room in order to visualize the step wedges and linearity square,
since they will be used again. You will want to use these same factors next time you expose the phantom.
