Quinnipiac University Diagnostic Imaging RS 240L Lab #1 Name: Karen Finn Objective: To illustrate how the Konica CR system is used and to become familiar with the Kalare radiographic room. The student will be able to manipulate the x-ray unit, process a CR imaging plate, set assigned techniques, and adjust a digital image. Equipment Used The equipment that was used during this lab were the Kalare radiographic room which included the Control Panel, Table and Table Bucky, table controls and X Ray Tube. While using the Konica CR system the CR plate reader and the image processing tools were used. Procedure: The first step in this lab was to become familiar with the Kalare X-ray room, which meant that each student used the lock on the x-ray tube and moved the tube around the room. Next, the x-ray table was moved transversely and longitudinally then the table was zeroed. The tube was also centered to the table using the Auto Centering button and the table was set to 40” SID. After becoming familiar with the x-ray room, there were groups of exposure factors that were set and the mAs values were recorded. Next, an exposure of an AP elbow was taken and the exposure factors were recorded. Finally, the x-ray was processed using the CR cassette where the film was placed inside the plate reader and the cassette was processed. Results / Discussion / Questions

Name: Karen Finn
Objective: To illustrate how the Konica CR system is used and to become familiar with the Kalare radiographic room. The student will be able to manipulate the x-ray unit, process a CR imaging plate, set assigned techniques, and adjust a digital image.
Equipment Used
The equipment that was used during this lab were the Kalare radiographic room which included the Control Panel, Table and Table Bucky, table controls and X Ray Tube. While using the Konica CR system the CR plate reader and the image processing tools were used.
Procedure: The first step in this lab was to become familiar with the Kalare X-ray room, which meant that each student used the lock on the x-ray tube and moved the tube around the room. Next, the x-ray table was moved transversely and longitudinally then the table was zeroed. The tube was also centered to the table using the Auto Centering button and the table was set to 40” SID. After becoming familiar with the x-ray room, there were groups of exposure factors that were set and the mAs values were recorded. Next, an exposure of an AP elbow was taken and the exposure factors were recorded. Finally, the x-ray was processed using the CR cassette where the film was placed inside the plate reader and the cassette was processed.
Results / Discussion / Questions
1. When a tube is set for 40” SID and a cassette is placed in the Bucky tray the SID increases 3 inches because the Bucky is now factored in.
2. The auto centering is used when moving the tube over the table; the tube is inline with the center of the table when the table is zeroed out.
3. If the tube was centered to the table and the table is not set at zero the x-ray would not be centered to the precise location, which could cause the x-ray to be missing some aspects of the image and it would be off centered.
4. Window level is used to adjust brightness and contrast.5. The table bucky is number one on the x-ray control.6. mA, kVp, and mAs are the 3 tabs that can be adjusted on the x-ray control.
