The RTI Scatter Probe is our revolutionary solid-state detector for leakage and scatter detection in X-ray environments.
Its unique design – two separate detector areas of 10 cm² and 100 cm² – fulfills current regulations and standards for X-ray leakage and scatter measurements. The Scatter Probe connects to our world-leading Ocean Next™ software for measurement reading and reporting.
Reliable dosimetry
For barrier, leakage, and scatter measurements various industry standards apply.
21 CFR 1020.32
21 CFR 1020.30
IEC 60601-2-54
IEC 60601-1-3
There are several more standards for various modalities.
Detector area
Common for all these standards is that the measurement must be made covering an area of 10 cm² or 100 cm² at a certain distance. The detector areas of the RTI Scatter Probe ensure full compliance with these standards.
It does not matter if your scatter and leakage application require measurements at a short distance, long-distance, in a fixed position, or sweep, with a click you can select the 10 cm² or 100 cm² area for your measurement.
Quick and easy positioning
Stand on a table, use by hand, or mount on the included tripod, the RTI Scatter Probe is quick, simple, and easy to position.
The anti-slip surface also allows safe positioning facing upwards without sliding.
With the standard camera tripod thread, the probe can be mounted to any tripod or jig.

The RTI MAS-1 is an invasive probe for the measurement of mA and mAs. Together with Piranha or the Cobia SENSE, direct reading of mA and mAs, as well as waveform, are obtained. The probe connects to the mAs socket in the X-ray generator and to the multimeter.
It can be used to measure tube current for both radiographic and fluoroscopic exposures.
The RTI MAS-2 probe is a clamp-on probe for the non-invasive measurement of mA (tube current) and mAs.
Safe and easy to use. The probe is simply clamped onto the high voltage cable and then ready for measurements. No connection inside the X-ray generator is needed! Together with your meter, direct readings of mA and mAs, as well as waveform, are obtained.
The Ion Chamber Magna 1 cc is designed for mammography dose measurement. With an excellent energy response, it can be used for radiographic applications too. It is the ideal choice for two reasons:
Evaluations of Magna ionization chambers show a response within ±1% over an extended mammography range of 20-50 kVp (HVL of 0.15 mm to 0.73 mm Al).
All mammographic mean glandular dose tables are based on in-air measurements.
The Magna’s air equivalent construction makes it ideally suited for in-air exposure measurements of mean glandular dose. Comes in a hard case for the best protection.
RTI CT Dose Profiler probe for use with our Piranha, Cobia FLEX, or Cobia SENSE (with PC com). Used for the evaluation of CT and CBCT systems. The probe fits into standard phantoms used for CTDI measurements.
One-shot accuracy
The RTI CT Dose Profiler has taken CT quality assurance to the next level. Because of its revolutionary design, it has transformed CTDI measurement from being inaccurate, due to underestimation of the dose for wide beams, to becoming more exact. It also has the ability to further analyze the result – all in one shot
The rapid advancements in CT technology are placing new demands on methods and equipment used for quality assurance. The wide beams of modern CT scanners make it difficult to use existing CT ionization chambers to measure the total dose given to the patient. Using a standard 10 cm CT ionization chamber may result in inaccurate measurements due to the underestimation of the dose profile for wide beams. The CT Dose Profiler was developed to solve this problem.
The following parameters are achieved from a single exposure:
CTDI(100)
Point Dose
CT dose profile
CTDI(w)
CTDI(vol)
DLP
Performance of the AEC
FWHM (Full Width at Half Maximum of the dose profile)
Geometric efficiency
All parameters are presented with high resolution and accuracy.
Due to the very wide beam and fixed table in Cone Beam CT, a detector must be moved very precisely through the beam to measure the right parameters. This can easily be done with the help of the RTI LoniMover™, in combination with a Pencil Ion Chamber or a CT Dose Profiler.
Following the IEC standard IEC 60601-2-44 Ed. 3:A1, the Pencil Ion Chamber can accurately and reproducibly measure the full CTDI for Cone Beams. With the CT Dose Profiler, you will get the FWHM, Geometric Efficiency, and full CTDI with only one measurement through the beam.
Updated to v.4.2
Measure CTDI for Wide Beam and Cone Beam CT according to the IEC 60601-2-44 Ed. 3:A1 standard. Remember, the LoniMover™ works well with any Pencil Ion Chamber of any brand.
Cobia SENSE & FLEX support
Many improvements have been implemented in the new LoniMover™ v.4.2. The biggest one is that the LoniCT software supports Cobia SENSE and Cobia FLEX so measurements can be received with the same software. The software can, of course, still operate simultaneously with Ocean Next™ software, so you can gather all your measured data in your sessions, as well as analyze, save, and autogenerate full reports.
Bluetooth® connection
With this solution, you can seamlessly use the LoniMover™ with a Piranha meter and other solutions from RTI. Even better, with built-in Bluetooth® everything is wireless and easy to set up!
Version 4.2
Scan up to 300 mm (and the Pencil Ion Chamber can cover 400 mm)
LoniCT software can be used with Cobia SENSE and Cobia FLEX
Bluetooth connectivity
LoniCT software can measure FWHM on pulsed profiles
More flexibility in scanning parameters
Mechanical fixes
More software functions, saving data, and settings
The RTI Dose Probe is an external dose probe, designed to perform very low dose rate measurements, for instance, on image intensifiers.
The probe is very small to avoid or minimize interference with AEC (Automatic Exposure Control) on X-ray equipment. This also enables it to fit into the table bucky.
Since it is a solid-state detector, no corrections for pressure or temperature are needed. Neither is polarizing voltage.
Dose probe for Fluoroscopy
The RTI Dose Probe is small and has a fast response which makes it ideal for pulsed fluoroscopy. It can detect individual pulses, determine pulse rate, and show waveform at dose rate.
The RTI T20 Dose Probe is a solid-state detector dedicated to measurements on Rad/Fluoro systems when it is crucial that the detector itself does not have any effect on the system output or disturb the X-ray beam.
It was developed for measurements of the patient entrance dose (skin dose) and the maximum dose rate in the radiographic and fluoroscopic field. Despite its small size, the RTI T20 Dose Detector is protected from picking up backscatter.
Place it anywhere
The RTI T20 Dose Probe can be placed anywhere in the X-ray field in contrast to many other detectors. The RTI Dose Probe, for instance, is small but not small enough in all situations. It still has to be placed outside the active area to avoid affecting the feedback of the system.
Independent and sensitive
The RTI T20 can connect to either Piranha, Cobia FLEX, or Cobia SENSE, and has a built-in correction filter that allows the detector to self-compensate for different beam energies. Therefore it has a flat energy response in the radiographic range with no need for correction factors. The RTI dose detector gives about five times higher sensitivity than a typical ion chamber.
IEC Directive
The RTI T20 Dose Probe fulfills the IEC directive for dose detectors regarding energy independence, measuring range, and angular dependency for RQR50–150 kV.

The RTI CT Ion (Ionization) Chamber is for use with the Piranha meters, Cobia FLEX R/F, or Cobia SENSE. The RTI CT Ion Chambers – 10 cm and 30 cm – are intended for CTDI and dose length product measurements on CT scanners in a phantom or free-in-air.
Both chambers can be connected via the RTI Chamber Adapter to the Piranha or to the Cobia. The 10 cm chamber can also fit into standard phantoms used for CTDI measurements. They fulfill applicable parts of the IEC 61674 standard for diagnostic dosemeters and are thereby compatible with IEC 61223-2-6 and 66601-2-44 for applicable CT dosimetry.
The chambers come with RQT9, 120 kV, and W/Al + 0.25 mm Cu as standard calibration. Please specify on the order if you prefer another calibration.
The RTI Chamber Adapter is an external module for connecting ion chambers to the Piranha meters, Cobia FLEX, or Cobia SENSE. The adapter upports ion chambers with LEMO triaxial connectors (e.g. RTI CT Ion Chamber, DAP chamber, and Magna 1cc mammography ion chamber).
