ENVIRONMENT CONDITIONS
Temperature: 15
o
C to 30
o
C
Humidity: 45% to 75 %
Atmospheric pressure: within the range 86,0 kPa to 106,0 kPa (645mmHg to 795mmHg).
Flammable Anaesthetics: the system must not be operated in the presence of
flammable anaesthetics.
BANDWIDTH
Scan rate dependent: low frequency cut-off (3db) 20Hz, 100Hz or
250Hz .
Selectable upper cut-off frequency (0.1db) 3KHz,
15KHz
or 22.5KHz. Default Bandwidth in Bold.
RANGE AND SCAN AREA
Standard Instruments
At 20cm distance, Normal area = 6.6cm x 5.5cm; Large Area =13cm x 13cm.
At 100cm distance, Normal Area = 25cm x 25cm; Large Area = 50cm x 50cm.
High Resolution Instruments
At 20cm distance, Normal Area = 2.5cm x 2.5cm; Large Area = 5cm x 5cm
At 30cm distance , Normal Area = 3.4cm x 3.4cm; Large Area = 6.8cm x 6.8cm
SCAN SPEED
Scan speed is approximately
4ms/pixel
, 10ms/pixel or 50ms/pixel (at maximum resolution).
Scan duration is typically 40 seconds for a 12.5cm x 12.5cm image at 64 x 64 pixel resolution, about
6 minutes for a 50cm x 50cm image at 256 x 256 pixel resolution at 4ms/pixel and 100cm distance.
SPATIAL RESOLUTION
Standard Instrument
Up to 256 x 256 pixels (actual measurements not by interpolation): 0.2mm/pixel at 20cm, 'normal
scan'; 2.0mm/pixel at 100cm, 'large scan'.
