Atomlab™ 500 Dose Calibrator

What are some of the new features with the Atomlab 500 Dose Calibrator?

The system consists of a new low pressure ionization chamber, electrometer with extraordinary linearity and an auto-ranging large touchscreen color display. Every element of the design and technical development of the Atomlab 500 will increase dose accuracy, department productivity and regulation compliance. The intuitive human interface guides the user through each operation. 

Has the Ionization Chamber been redesigned?

Yes, in the newly redesigned low pressure Argon gas chamber, activity measurements are preformed by a microprocessor controlled electrometer located within the chamber assembly. 

How are the measurements displayed?

Activity measurements are displayed on the touch screen color display in either Curie or Becquerel units. Background correction is performed at the touch of a button. Activity range is automatic from .01 microcuries to 40 curies of Tc-99m or 10 curies of F-18. 

Does the new Dose Calibrator meet regulatory requirements?

Yes, the Atomlab 500 Dose Calibrator provides fast, accurate readionuclide activity measurements with performance that easily complies with the most stringent regulatory requirements.

How is the Dose Calibrator shipped?

The new low pressure chamber allows the system to be shipped by air or ground transportation as standard goods. 

How is the Isotope Library set up?

The library of 89 isotopes and their specific dial values is listed in the system's memory. Dial values can easily be changed "on the fly" if required. From this library, isotopes may be placed on lists so they can be readily available to the user. There are 12 isotope selection buttons that can be programmed by the user for the isotopes they routinely use in the lab. Additionally, from the isotope library, another 24 isotopes can be designated for a routine list. A user may also create up to 20 custom isotopes to add to the library. 

How is inventory handled?

The Atomlab 500 provides inventory control for 25 isotope samples/kits, storing and correcting for volume, activity and moly concentration. When drawing a dose from an inventory sample/kit, future dose as well as volume calculations for specific times can be displayed. In addition to inventory management, the Atomlab 500 provides quality assurance and record keeping functions as well as hard copy records produced for all functions. The label printer allows the user to print labels for the syringe or vial.

What is the QC program for evaluation?

The system features an exceptional QC program for evaluating the radiopharmaceuticals. The Atomlab 500 performs all counting and calculations for paper chromatography tests by computing the percentages of free, hydrolyzed reduced and bound radiopharmaceutical.

How many units can be connected?

Up to seven ionization chambers or six ionization chambers and a wipe test counter can be connected via RJ-12 cable “daisy chained” to a single display unit. The activity in each detector can be selected and viewed from this display.

How are quality assurance tests conducted?

The Atomlab 500 simplifies dose calibrator quality assurance with programs for constancy, expanded constancy and geometry. The system stores and decay corrects multiple reference sources and compares the measured activity to the calculated activity for the daily constancy test.

What is the expanded constancy test?

A special program called an expanded constancy test allows the user to measure a long-lived source and up to 14 routinely used isotope settings, all in a matter of seconds with just one touch of the screen.

How are linearity tests performed?

Linearity tests can be performed in the traditional manual method or by a fully automated program that allows for readings from a source to be taken and automatically recorded at specified intervals. The system will graph the results.

How is the attenuation tube test performed?

The attenuation tube test for linearity can be performed using software that will guide the user through the procedure, store the values and make all calculations.

How is accuracy performed?

Accuracy is simply performed by recording three measurements of a suitable NIST traceable source. The system calculates the average reading and compares it to the calculated standard and then determines the average variance. If any readings are out of the acceptable range, they will be highlighted in red. 

What information is archived?

The display unit of the Dose Calibrator can store QA test data, isotope and kit inventory to memory and can be printed at any time with an optional compatible printer. 

Can the system interface with other systems?

Yes, the Atomlab 500 Dose Calibrator features a RS-232 bidirectional serial communications port which may allow the display to communicate with most commercially available nuclear medicine management systems. 

How are system software upgrades done?

The bidirectional serial communications port will also allow access for easy upgrades to the system software via the Biodex website. With the optional Atomlab 500 Data Manager software, data can be exported from the Atomlab Display Unit to any Windows-based PC. The software can generate individual reports for each of the QA tests performed on the Atomlab 500 Dose Calibrator.
