3–2–2
Magnification
Note:
Use of the bucky is not recommended in magnification. The operator should use
the cassette holder.
Note:
Always make sure that the magnification plate is correctly locked in place before
starting an exam.
When magnification is selected, the system automatically selects the small focal spot (0.1).
Note:
When standard examination is selected, the system automatically selects the large
focal spot (0.3).
To maintain optimal image quality, the user must check on the control panel display that the
selected focus is dedicated to the selected examination mode:
Contact examination (normal) = 0.3
Magnification = 0.1
The object-film distance depends on the coefficient of magnification required.
Note:
Refer to the magnification values in Table 1–1, Chap 1.
Select configurations and kV values given in manual mode,Chap 2, Para 2–3. Refer to
Tables 2–1 and 2–2, Chapter 2.
Using an increase of 1 thru 2 kV will reduce exposure time.
Note:
Refer to Tables 2–1 and 2–2.
3–2–3
Examination of Chest Wall
Select configurations and kV values according to the thickness and density of the region
examined.
Select parameters from Tables 2–1 and 2–2.
It is recommended to use the Bucky.
Use of the bucky is not recommended in magnification.
3–3
Manual Mode
The Manual Mode can be used for standard exposures, implant views, magnified
exposures, or for the examination of the chest wall.
It is recommended to use Manual Mode when the object to be x-rayed cannot be correctly
positioned over the cell of the AEC.
