9. OPERATION OF THE MACHINE
9.1. OPERATION PRACTICES
A. Wear a lead apron while you make exposures.
B. Stay distance at least 2 m from the unit or extend the cord of hand switch as long as possible in
order to secure enough space for your safety.
C. Use proper field size and technical values for each procedure to minimize x-ray exposure dose
and gain the best radiographic result.
D. Be careful about the decimal point on the mAs display in order to acquire intended mAs values.
E. When you make exposure to the patient on the bed, ask visitors to leave the room first and
keep appropriate distance from the patient.
F. Pay attention to the maintenance schedule of the device and keep up with it.
G. Cumulative radiation dose usually does not exceed recommended maximum levels. However, if
you make radiographic exposures using high kV and mAs quite often, the evaluation of the
specialist is needed to check whether extra protective devices are necessary for the user or not.
WARNING
Please check weather the voltage and frequency of the power supply are in
accordance with the figures written in the system labels, which attached on the
body of the machine. The levels of voltage should move within ±10% of the
nominal values.
CAUTION
The operation of the machine should not be started unless all verifications and
connections are fully prepared.
9.2. POSITIONING OF PATIENT
A. Place the loaded cassette on the patient’s backside.
B. Arrange the SID (Focal Spot to Image Receptor Distance) using a scale located on the side of
the collimator.
C. Turn on the collimator lamp and laser pointer by pushing collimator/laser on switch.
D. Adjust the size of the x-ray beam in accordance with the film size using the x-ray field
adjustment knobs. Turn off the collimator and laser pointer after 30 seconds on the timer.
10
CAUTION
For the first installation of the machine or operation after long period of non-use, it
needs to be preheated to secure long service life of the tube. Following method of
pilot test will relieve the damage on the x-ray tube. Operate the machine with low kV
values (50kV 5mAs) three times in row and execute with higher values [70kV 5mAs]
three times in row again. Then high kV values [90kV 5mAs] will be applied without
big troubles or pressures on the machine.
