The TNT 12000 X-Ray Test Device is the newest and most versatile instrument available for measuring key x-ray imaging parameters. It sets up in seconds and measures kVp, Dose, Dose Rate, time, and HVL in a single exposure. A totally-wireless ZigBee® communications protocol enables quick and easy setup and the wireless detector can be used with the companion wireless display or a laptop computer. Instant half value layer (HVL) with just a single exposure further enhances productivity.
The quality assurance and service of x-ray imaging equipment is a precise and often time- consuming task. Professionals charged with the responsibility of assessing and maintaining x-ray imaging systems need to carry out their tasks with flexibility and the most accurate and reproducible results using a productive, cost-effective process. The TNT 12000 is designed specifically to meet these needs. It is the most productive instrument of its type available and sets a new standard for efficiency for users from a variety of technical backgrounds. TNT 12000 ease-of-use is suited for the most complex analysis that might be required by a physicist to the more routine needs of a state or local inspector. Time is of the essence, and the TNT 12000 puts control of time and productivity in the hands of the user regardless of the complexity of the task.
Productivity and accuracy are central goals when performing any maintenance or QA process on diagnostic imaging equipment because image system uptime is critical to patient care objectives. TNT 12000 is small, portable, and wireless. It is easily transported to the imaging room, set-up in seconds, and all results are instantly available on the handheld display or on the user’s laptop. The latter application places measured values into templates that are standard with the Excel software provided with TNT 12000. Because the TNT 12000 Excel package is a spreadsheet, users can customize their templates and create their own reports to send to others. When used with optional Ansur computer-based software plug in, the TNT 12000 allows for standardization of test procedures, as well as result capturing, storage, and printing of reports.
