Tubestand Technical Information
5.2 Compression
5.3 X-ray Tube
Manual Compression Force
Maximum of 300 N (67.4 pounds)
Motorized Compression
Functions in three operating modes, Pre-compression, Full-
Range, Dual Compression, user selectable through
software
Pre-Compression Force
15 pounds to 30 pounds (67 to 134 N), motorized
Full Range Compression Force
20 pounds to 40 pounds (89 to 178 N), motorized
Dual Mode Compression
Provides Pre-Compression force upon first activation of
compression switch; then, if switch is activated within 2
seconds, the force is increased incrementally for each
additional switch activation, up to the user selected full
compression force.
Compression Controls
Up/Down controls on both sides of C-arm and on
2-position footswitch (Motorized). Handwheel on both
sides of Compression Device (Manual).
Compression Release
Manual or Automatic. Motorized Release mode controlled
by push-buttons on both sides of the C-arm.
Automatic Compression Release
User selectable automatic release mode raises
Compression Device upon exposure termination.
Down Motion Variable Speed
4.2 cm/s ±15% (1.66 inches/s ±15%)
Compression Force Display
Two LEDs on the Compression Device show the
compression force through the range of 44.5 N to 300 N
(10 pounds to 67.4 pounds) in 4.4 N (1 pounds)
increments.
Compression Force Display Accuracy
±20 N (±4.5 pounds)
Compression Thickness Display
Two LCDs on the Compression Device measure between 0
and 15 cm above image receptor in 0.1 cm increments.
The display is visible from both sides of the patient.
Compression Thickness Accuracy
±0.5 cm (±0.2 inches) for thicknesses between
0.5 cm and 15 cm (5.9 inches)
Compression Paddles
Compression Paddles are transparent. The paddles are
composed of polycarbonate resin or the equivalent. With
compression applied, paddle deflection from a plane
parallel to the patient support surface shall be less than or
equal to 1.0 cm.
Focal Spot
Large (0.3 mm) Nominal
Small (0.1 mm) Nominal
Tube Voltage 20 kV to 49 kV
Anode Material Tungsten
X-ray Window Beryllium 0.63 mm
