Product Description:
Unigamma Compact
Unigamma Compact : permits to perform the most important surveys with great cut in costs and without any decrease in quality. Compact is driven by a windows program which is well known as a user friendly operating environment.Theperformances of Compact are enhanced by a clear and easy to read graphical presentation of the results. Displayingand printing of the results may be performed in color or black and white mode. Ink Jet or Laser printer are supplied with Compact.
Low exposure:
The patient exposure is lower than 100 µS for a forearm survey and lower than 500 µS (5 mR) for the other surveys. The scan times considered are 6 min. for femur and spine and 4 min.for the forearm.Exposure to the operator is null at 1 m of distance.
 
Double energy:
• Radiant source:86 KV x-rays,collimated with a cylindrical hole of depth 40mm.Energy splitting by
 
• Samarium filter: 35 KV and 75 KV. With this system the scan speed has been improved. Scan time is only 50 % of that required for the former single energy method.
Windows software:
The windows software to drive Compact is a big progress in bone densitometry. It is a powerful tool to acquire and analyze the scans,thanks to the high speed and to the simple use of the operating environment Microsoft Windows. The most part of the operations are performedwith simple mouse clicks using the graphical user interfaceof windows.
 
Quality control:
•Quality control on line with automatic recording of internal reference standard for every scan. It is possible to store themeasures of the reference standard supplied with Compact to
perform statistical controls
• Calibration autocalibrating system with check of internal reference standard before any scan and automatic centering of the peaks of the radiant beam.
 
Laser pointer:
The starting point of every scan is obtained using a laser pointer. This method allows fast and repea-table positioning of the patient.
 
Easy transportation:
Compact consists of a main body set on wheels, which dimensions ( 78 x 125 x 136 ( height)) allow its shifting through corridors or doorways not larger than 80 cm. It can also be loaded easily on a small truck and brought around, for home based scans for example
 
Unigamma Plus
Unigamma Plus is the newest multi-detector, fan beam bone densitometer manufactured by l'acn. The 5-channel architecture scan times and better image resolution. Moreover, the small fan-allows reduced beamconfiguration minimizes the geometricaldistortion, even on whole body scans. For special applications, itis also possible to use the unit in a pencil-beam mode, using only the central channel.The performances of Plus are enhanced by a clear and easy to read graphical presentation of the results.Displaying and printing of the results may be performed in color or black and white mode. Ink Jet or Laser printer are suppliedwith Unigamma.
Low exposure:
The patient exposure is lower than 100 µS for a forearm survey and lower than 500 µS (5 mR) for the other surveys. The scan times considered are 6 min. for femur and spine, 4 min. for forearm and 20 min. for totalbody. Exposure to the operator is null at 1 m of distance.

• Spine
• Femur
• Forearm
all district to scan and all the other scan parameters can be selected directly by the operato
 
 
Videogamma Rack
Thanks to its advanced technology and automatic peak centering,VIDEOGAMMA RACK permits to measure any kind of gamma emitting radioisotope. A personal computer linked by a RS-232 serial port may be connected to the device. The software installed on the PC ensures easy and efficient handling of the gamma counter and data processing
Completely automatic
It is the first RIA system , which allows the operator not to manipulate the rack. The racks have to be placed on the apposite operating surface of VIDEOGAMMA RACK. After having specified their characteristics on the Computer all the tubes are measured in a completely automatic way.Besides there are procedures which allow:
1. Automatic system calibration with automatic centering of the energy peaks.
2. Automatic control of the motors used to move the tube carrying system.
 
Radioactivity and RIA measurements
VIDEOGAMMA RACK benefits from the entire progress made by l’acn in RIA measurements since 1975. It is possible to use acquisition data and widely used software to perform:
• RIA/IRMAtest
• Hepatitis
• Allergology
• Fittings: Point-to-Point, Parameters,
Logit-Log, Spline
Quality Control
1. On-line with displaying of the results and comparison with preceding acquisition data.
2. Graphics showing 9 parameters for comparison with reference data
 
Best Efficiency
The special design of the detector’s crystal allows measurements with maximum geometrical efficiency.
 
 
 
Gammacal- Dose Calibrator
Gammaca is a dose calibrator based on the principle of the ionization chamber. It is suitable for measuring automatically doses of gamma ray emitting ionization chamber ensures high uniformity for different volumes to be measured. So the matter to be analyzed can be contained for example in a small bottle used for storage or directly in a syringe.
It uses a microprocessor for connection with a Personal Computer. The connection is established by a standard serial port. In this way the only button present on GAMMACAL is the master switch.GAMMACAL is controlled in both phases, acquisition and data elaboration, by the keyboard and the mouse of the personal computer. So these instruments are the main instruments to interfacethe with the operator.
The programs are designed for Microsoft Windows. This permits flexible use of the device, also using for example a net.
The most evident advantage for the operator is the possibility to perform measurements of radioactive sources from high distance which ensures zero exposure and thus maximum safety.
It is calibrated for the most common radioisotopes used in nuclear medicine . On the other hand itmay be used too for any other type of radioisotope , using a simple calibration procedure implemented in the software.
The software in English language can be updated to match completely actual legislation
