Frequently Asked Questions

Yes, the Piranha 657 can measure dental/panoramic units. The user simply selects the Dental or Panoramic option in the display. With the help of the “Position Check” function, the Piranha can be accurately placed so that the Piranha detector area is uniformly radiated. There is also an optional “Panoramic Dental Holder” which fixates the Piranha for easier and accurate Panoramic measurements.
Measured values can include kVp, time, dose, dose rate, TF, and HVL. Full waveforms are available with either the PDA QABrowser software or the laptop Ocean software. Dental measurement capabilities are standard on all 200, 500, and 600 series Piranhas.

Yes, by using the Ion Chamber Adapter from RTI Electronics an ion chamber can be connected to the Piranha. Please check with us to make sure your current Ion chamber is fully suited for the bias module.

Yes. Any RTI MAS Probe can be used simultaneously with the Piranha during an X-ray exposure, making it possible to display up to 8 parameters at one time: kVp, time, dose, dose rate, TF, HVL, mA, and mAs. Additionally, kV, dose and mA waveforms are available with each exposure, with either the PDA or laptop.

Yes, there should not be any problems if the USB cable is being used. How to use Bluetooth with Vista and Windows 7 is described in the oRTIgo and QABrowser manuals.

We give demonstrations while traveling around the world to participate at different exhibitions. It is also possible for you to contact us and get a private demonstration where you are able to get answers to all your questions and take your time to learn more about the instrument and model that best suits your needs.

RTI recommends a recalibration after two years.

RTI usually releases two updates each year. In each release new features are presented which will simplify the measurements and analyze of the results. These new features have usually been initiated by RTI customers' needs and wishes. These updates can be down-loaded from the RTI webpage. Just log in with your serial number.

No, simply follow the instructions on the RTI web page to upgrade your system.

Yes, and it standard on all Piranha 500 and 600 systems. This calibration has been available for RTI products since 2007.

A fully charged Piranha can be used for up to 15 hours, and can be charge and used simultaniosly. The Piranha can be charged via a regular wall outlet or the supplied USB cable connected to a laptop.

The RTI Piranha has a battery life of up to 15 hours. Below are the indicators shown when the battery is discharging:

1. Green light – battery level over 25 % (4 hours left)
2. Yellow light – battery level between 10 and 25 % (1½-4 hours left)
3. Red ligh – battery level below 10 % (<1½ hours left)
4. Flashing Red light – <15 minutes

Yes. Measurements made with a Piranha 657 can be saved with either the Palm PDA with QABrowser software or with the Ocean laptop software. The digital data is transferred via an Excel Add-in when using the Palm PDA. The Ocean software is an Access database X-ray QA software package that allows the user to create customized templates for easy measurements and archiving of all measure data and waveforms. Non-measured data can also be included in reports that are easily edited and printed.
Ocean allows for a variety of different looks that suit the user, providing for the greatest flexibility, operation and organization. Output is available to PDF, Excel and Open Office.

Ocean Central is a database software that makes it possible to tie all Ocean users together via network and internet. With Ocean Central you can save all measured data in one place and easily distribute templates to all users.

Simply choose Pulsed Fluoro with the Piranha QA Browser software or Fluro and Frame-rate with Ocean software. This will work with either the Piranha or its external dose detector. With Ocean you can also measure a lot of other frame parameters like total frame count, dose/frame, pulse width etc.

There are a number of ways to do this with Ocean. One way is to choose TIMED MODE and make a single measurement to include all the exposures. The result will be your accumulated value. The second option allows the user to make any number of measurements and simply add the values at the end of the exposure sequence.

The Piranha can measure the correct kV on very low dose rates and for the whole kV spectrum. For example, the Piranha can measure 43 kV at a dose rate of 30 mR/min at 25 GA consistently and with no special set-up.

Yes. The Piranha can measure as low as 30 mR/min (or even lower). Basically, as long as the Piranha can measure dose rate, the Piranha measures correct kV.

The Piranha has multiple solid-state detectors that measure simultaneously during any exposure. Some of these detectors are dedicated to measure kV and Total Filtration (TF). The correct HVL is calculated by knowing the kV and TF values. The QABrowser and Ocean software both automatically provide this value in a single exposure for R/F, Dental and CT.
The user can also measure HVL the conventional method using aluminum sheets. Simple, ready-touse HVL applications, including HVL graph, are included in the QABrowser and Ocean software packages.

One. All measured parameters (kV, dose, time, HVL, total filtration, frames, dose rate, frame rate, etc.) and you will also get the waveform.

RTI Electronics introduced Bluetooth technology in the multimeters in 2002. This easily accessible wireless technology eliminated unnecessary cables from the console on QA equipment and made set-up easier and faster.

Cables require time to set up and put away after use, which reduces productivity. They are prone to damage, especially at the connector ends, and can be bumped or stepped on during operation-causing erroneous readings, delays and other productivity challenges.
