AcMe activity meter is a family of Dose Calibrators based on field proven state of-the-art technology.
The high precision innovative electrometer, coupled to a deep-well Argon filled Ionization Chamber, allows the highest measuring accuracy and stability.
A rational and user-friendly Windows-based HMI provides clear measurement results and full control of the device in terms of QC, data management, report and label generation.
To increase geometric measurement accuracy, the system gives user the unique capability to insert for each isotope an indefinite number of geometries, all stored in a permanent database. This features greatly reduces measurement errors in particular when measuring pure-beta emitters.
AcMe is available in the following configurations:
- Stand Alone model (for QC Laboratories)
- Hot Cell model (installed inside hot cells and safety cabinets).
Software HMI can be installed over any Windows® 10 based system.
AcMe Dose calibrator general specifications
- AcMe is based on Argon filled well-type ionization chamber directly coupled to a high accuracy smart electrometer
- Electrometer is microcontroller based and performs automatically all measuring tasks, autozeroing, background, bias and gain digital control. The microcontroller continuously check the working parameters of the electrometer and send error codes to main HMI software, thus greatly reducing measuring errors due hardware malfunctioning
- Functionalities like quality control, generation of reports and labels, make it the ideal tool for all operations of activity measurement in nuclear medicine departments and PET centers
- PC with touch screen monitor
- More than 25 calibration factors stored for the radioisotopes most commonly used in Nuclear Medicine
- System can store up to 110 isotope selection
- Nine customizable user-settable fast keys for Isotope selection
- Geometries pre-set: Vial and syringe.
Additional user-required geometries (unlimited number) can be set and calibrated easily
- PDF report generation and label generation both for patient or for production purposes. Reports and labels are permanently stored in SQL database
- Data are permanently saved in a SQL database, with USB export capability and TCP/IP protocol interface
- Two-level password-protected device
- Label printing capability
- Ethernet TCP/IP output for interface with external systems
- HMI software can reside on any Windows 10 based PC and provides easy to use and intuitive interface
