4.3 X-RAY BEAM ALIGNMENT WITH RESPECT TO PATIENT
100
After selecting RAD parameters for the technique to be performed:
1. Point the X-Ray Tube-Collimator Assembly to the Image Receptor (refer
to Illustration 4-32.)
2. Center the Collimator light, which corresponds to the X-Ray beam, with
respect to the receptor. For that, use the Collimator Light centering
marks and the laser line on the receptor handle if applicable.
3. Position the patient for the examination.
4. Turn ON the Collimator Lamp and adjust the field size with the Collimator
controls.
5. Perform any adjustment on the patient position, receptor or tube
collimator assembly to assure that the X-Ray beam is correctly
positioned.
ALWAYS SELECT THE CORRECT FIELD SIZE TO AVOID
EXCESSIVE RADIATION.
THE X-RAY BEAM AXIS AND THE REFERENCE AXIS OF THE
PLANE OF INTEREST COINCIDE AND ARE ORTHOGONAL
WITH RESPECT TO THE PLANE OF INTEREST, IN EXAMS
PERFORMED
PERPENDICULARLY POSITIONED WITH RESPECT TO THE
TUBE-COLLIMATOR ASSEMBLY.
IN CASE OF EXAMS WHERE THE IMAGE RECEPTOR IS NOT
PERPENDICULARLY POSITIONED WITH RESPECT TO THE
TUBE-COLLIMATOR ASSEMBLY, THE X-RAY BEAM AXIS
DOES NOT COINCIDE WITH THE REFERENCE AXIS OF THE
PLANE OF INTEREST AND IT IS NOT ORTHOGONAL WITH
RESPECT TO THE PLANE OF INTEREST. THEREFORE, THE
RESULTING IMAGE WILL BE DEFORMED.
IT IS THE OPERATOR RESPONSIBILITY THE PROPER
POSITIONING OF THE PATIENT AND EQUIPMENT BEFORE
PERFORMING AN EXAM.
