-
Manufactured
according to resolution Nº 1030 of the Comisión Nacional de Energía
Atómica (CNEA, the National Atomic Energy Commission of Argentina) of 07/DEC/1987.
-
Calibrated
with certified sources of CNEA (99mTc, 131I, 67Ga). Optional: F 18 or other
isotopes.
-
Activity
range:
1 microCi to 3 Ci of 99mTc.
-
Accuracy: +/-
5% depending on available certified sources.
-
Detector :
pressurized ionization chamber with argon. Remote.
-
Shielding:
3 mm width lead interior lining. Optional shielding of 50 mm Pb for using
also 18F.
-
Energy range:
gammas up to 1.3 MeV.
-
Geometry correction: not
needed up to 50 ml.
-
Activity
display:
on screen, floating point, in mCi or GBq reading. Automatic scaling
(autorange) or preset ranges. Automatic
reading averaging (as a function of activity) or manually preset (from 2 up to
1000
readings) to decrease statistical error.
-
Radioisotope selection:
on screen, from a list where user's favorites are at the beginning, ordered
as the user selected. More than 25 isotopes included from factory. Users may
add as many as they want. Half lives can be entered in seconds, minutes,
hours, days or years.
-
Calibration: automatic. You only need to measure a certified source,
type its activity and press a screen button. Calibration constants may be
listed and retyped if the isotope was erased by mistake, no need to get a
certified source again.
-
Background: automatic subtraction.
It resets to 0 when the system is turned on. You can put it in 0 at any time
manually.
-
Results printing: all measurements or only selected ones can be
saved into a text file with programmable columns (isotopoe, activity, date
and time, etc.) that ypu can print with Notepad or similar, or copy into a
spreadsheet like Excel or others. Individual results can also be printed for
labeling doses, including patient name, directly to a printer or as JPEG
images. If Wi-Fi is available, saved measurements can also appear
automatically in all the other devices connected to the same OneDrive
account.
-
Continuous monitoring: on screen and (optionally) also printed to a
text file, with programmable intervals during a preset time. An alarm level
may be set (with sound and/or marked on the text). It allows both monitoring
background (without a source) as testing stability.
-
Integrating measurement:
accumulated dose in a programmable time.
-
Digital thermometer: temperature is continuously mesaured inside the
ionization chamber and displayed on screen. Automatic recalibration is done
when necessary.
-
Radionuclide stock management module:it
allows to record available activity and volume for each isotope in the list.
You may also distinguish sundry radiopharmaceuticals with the same isotope.
It calculates volume to extract given the wanted activity, activity in a
given volume, and remainder, taking decay into account.
-
Adapter mains input: voltage: 100-240 V
AC; frequency: 50-60 Hz; current: 0.4 A max.
-
Adapter output: voltage: 5 V
DC; current 2 A max. (Tablet charging its battery and ACTusb running need
about 1.3 A.)
-
Temperature:
10 a 35°C (environment).
-
Humidity: 85%, non-condensing.
-
Connectors: USB (Type A) for
the ionization chamber, and microUSB (Type B) for the external charger of
the tablet. The chamber does not need any other connection.
-
Tablet specifications: Intel quad core processor. 2 GB RAM. 32 solid
state drive. Micro SDHC/SDXC card support. Wi-Fi 802.11 b/g/n + Bluetooth
3.0. Touchscreen: 8.9". Resolution: 1280 x 800. Battery: Li-polymer, 5600
mAh (autonomy: about 4 hours). QWERTY keyboard, detachable. Front and rear
cameras. Internal mic and speakers, connection for external. Tablet
specification may change.
-
The
system can also run on laptops or PCs without touchscreen, even with older
operating systems (like Windows XP, 7 or 8), though these may limit the
ability of synchronizing with other devices in the cloud. Wi-Fi is required
for tablet connectivity with other devices, not for using the dose
calibrator.
