TNT 12000 X-ray radiation dosimeter test tools

The waveform is accurate enough to assess whether there are problems in the X-ray tube or generator not disclosed by the numeric measurements. To obtain more accurate waveforms or to perform calibrations using the waveforms the 35080M199 X-Ray Scopemeter is recommended.

With the TNT 12000 solid-state detector or DoseMate dosimeter set to fluro mode, position either detector with the measuring side facing the X-ray tube at the prescribed distance from the focal spot. Completely block the image receptor using copper or lead sheets and begin the test.

Any firmware or software upgrades that do not affect calibration of the TNT 12000 are available on the Fluke Biomedical website under Support: Software Downloads.

There are five different possibilities:

1. Blue - Display or detector is connected to a power source and the battery is fully charged.
2. Green - Display or detector is connected to a power source and the battery is charging.
3. OFF - Display or detector is not connected to a power source and is operating on battery power.
4. Yellow - Display or detector battery has approximately 20% of charge left.
5. Red - Display or detector battery has approximately 10% of charge left and will turn off in two minutes.

One. All measured parameters (kV, dose, time, HVL) are displayed all the time with each exposure, saving valuable setup time. Because TNT 12000 always defaults to the previous settings when powered down, many repetitive QA and calibration routines can be set up and completed by the stroke of a single on/off key.

Yes it is possible to perform kV and other X-ray tube parameter measurements for the standard dental X-ray tube (TNT12000WD may need to be attached to a camera tripod to hold it in place in the beam.) Panoramic dental X-ray, like other modalities where the X-ray tube is rotating/moving, requires the tube be kept in place (not moving) to measure X-ray tube parameters. If dose is the parameter of interest, use DoseMate and an appropriate ion chamber capable of detecting X-ray energy in a 360 o arc about its center. There is no special calibration needed in either case.

A minimum of 500 mR/min doserate is needed to get accurate kV results.

Yes and it is standard on all TNT 12000 systems.

Each of the two sets of cross-hairs on the TNT 12000 solid state detector are marked as to their use. The gray-colored cross-hairs are for Rad/Fluro, while the red-colored cross-hairs are for Mammo. These aid in centering the detectors in the X-ray beam

PPV means practical peak voltage and is a measurement used outside the USA for assessing X-ray tube performance.

The TNT 12000WD was performing an internal amplifier nulling process but detected a start of X-ray shot and gave an error message.

Both the Excel add-in and Ansur Test Automation software automatically capture test data and facilitate data management and reporting. The Excel add-in collects measured values and populates a customizable Microsoft Excel spreadsheet template; A MQSA-specific template is included for Mammo applications. Ansur provides a visually-guided inspection procedure that reduces human error with step-by-step visual instructions, auto-configuration of compatible test instruments, auto-data collection of measured values from compatible test instruments, auto-comparison of measured values against pre-determined test limits, and objective determination of Pass/Fail. All inspection results are included in a single, test result file and customizable test report that can be printed or stored digitally. Ansur Test Automation software is also compatible with a range of CMMS software systems. All users may utilize the Excel add-in for reporting purposes. Users who need to standardize testing and reporting procedures (especially when performed by multiple associates) and minimize risk of human error benefit from Ansur Test Automation software.
