EMM-1Ch but it has two channels that can be used independent of
each other allowing you to measure with two external detectors
simultaneously.
One channel electrometer with built-in polarizing voltage supply (bias)
and floating input. This module is required when using ionization
chambers with LEMO connectors (BNT or TNT adapters are available).
The bias can be turned off, allowing use of solid-state dose detectors,
light detectors, and mAs probes. The bias voltage is user selectable
between –300 V and +300 V. A yellow LED is indicating when the bias
is activated. Note that turning on and off the polarizing voltage (bias)
takes approximately 15 seconds.
Warning: Always make sure that the bias is off before connecting
detectors.
One channel electrometer with built-in polarizing voltage supply (bias).
It is the same as EMM-Bias but the bias voltage can be output either as
a floating input on the LEMO triaxial connector or on the 3 mm banana
connector.
This means that this module supports both ion chambers with triaxial
connectors (LEMO, BNT, or TNT connectors) as well as BNC/Banana
connectors.
One channel electrometer with built-in polarizing voltage supply (bias).
It is the same as EMM-BiasB but it can only be used with unipolar
positive current detectors, like R100B, MAS-2B, and ion chambers.
This module supports both ion chambers with triaxial connectors
(LEMO, BNT, or TNT connectors) as well as BNC/Banana connectors.
Modules can easily be uninstalled or installed by the user at any time allowing easy
upgrade or solve technical problems without sending away the complete Barracuda
system for service. Read more in the topic Exchange of modules .
The Multi-Purpose Detector (MPD)2.3
The Multi-Purpose detector is a universal detector used for all type of X-ray systems;
radiography, cine, fluoroscopy, pulsed fluoroscopy, mammography, dental, panoramic
dental, and CT. You can measure the following parameters in one exposure with the
MPD:
· Tube voltage (kVp)
· Exposure time
· Dose (CT dose requires a special CT ionization chamber)
· Dose rate
· Dose/pulse and pulse rate
· Total filtration (radiography, fluoroscopy, dental, and CT, 50 - 150 kV, 1.5 mm to
38 mm Al)
· Quick-HVL (radiography, fluoroscopy, dental, and CT, 50 - 150 kV, 1.2 mm to
14 mm Al)
· kVp waveform
· Dose rate waveform
The estimations of total filtration and Quick-HVL are done from one single exposure
using a combination of detector and filters in the MPD. In situations when the total
