MAGNIFICATION
See Illustration 1–4.
The Receptor-Support Arm consists of the following:
Guide Rail 3 and Compression system including variable SID, magnification plate,
and compression paddle.
SID change is made via one of the two levers 5 located at the bottom of the handrails,
D
one on either side of the column. Push lever 5 first to engage the mechanism, then turn
lever 5 forward to release mechanism and change SID.
Three SIDs are available: 660, 610, and 560.
The 510-mm SID is reserved for the installation of the Stereotix 2 or
Senovision Stereotactic positioners. With a SID of 510 mm and in the absence
of Stereotix 2 or Senovision Stereotactic positioner, exposure is inhibited and a
warning message appears on the console readout.
The Magnification Plate 7 is installed by latching the plate onto the Receptor Arm
D
in the holes provided for the selected magnification and located on either side of the
Receptor Arm.
To unlock the magnification plate, press the lever located on the left of the mag. plate,
and pull the plate forward (as shown on label on top left side of plate).
Always make sure that the magnification plate is correctly locked in place before
starting an exam.
The middle and bottom holes provide the following magnification levels:
The magnification factors are defined in the middle of a 4 cm thick breast, i.e.
2 cm above the magnification plate.
