WHAT WE DO
Radalytica is the leading provider of robotic imaging solutions
for non-destructive testing. Our mission is to deliver top-class,
easy to use 2D and 3D robotic imaging system (RIS).
Our services are based on state-of-the-art imaging
technologies such as air-coupled ultrasound, photon counting
X-ray imaging detectors, computed tomography and more to
improve client’s quality control.

TECHNOLOGY
We develop advanced robotics technology to control multiple
robots integrated in a single imaging system. The system can
inspect advanced composite materials with complex curvatures
using air-coupled ultrasound probes and/or X-rays. The new
generation of X-ray imaging detectors provides unprecedented
image quality that helps eg. identifying impurities in materials and
products, bubbles, cracks, foreign objects, misalignments, etc. It
has a wide range of applications in aerospace, automotive,
healthcare, laboratories and many other industries, all at
micrometric level in 2D or even 3D image.

ROBOTIC IMAGING SYSTEM
RIS is modular with several imaging options such as spectral X-ray, computed tomography, ultrasound,
thermography and so on. It is a powerful platform, yet easy to customize and combine several imaging
techniques.
In classical X-ray imaging systems, both the X-ray tube and the detector are fixed or more only in a
limited range of directions (left, right, up, down). Hence, it is not easy, or even possible, to inspect
selected areas of larger structures, especially when they have complex shapes. Contrary to the classical
X-ray imaging setups, the robotic system gives nearly absolute flexibility of viewing angles. Therefore,
robots allow „looking“ with X-rays from a different perspective to localize the defects easier, faster and
better. RIS makes the X-ray inspection as easy as visual control.

ROBOTIC IMAGING SYSTEM
RIS supports air-coupled ultrasound to inspect advanced composite materials. The robotic arms offer
high degrees of freedom in following the complex curvature on both sides of the inspected object.
Therefore, it is suitable for shaped samples such as aircraft fuselage, wings, propeller blades, etc.
Moreover, the robots allow measuring 3D images using computed tomography or tomosynthesis in
region of interest of a large object. These are commonly used methods in X-ray inspection, but with
limited applicability on large objects. Robots overcome this limit. The robotic imaging system could be
used in quality control labs or built into production lines.

ADVANTAGES OF THE ROBOTIC IMAGING SYSTEMS:
- Modular: combination of imaging methods
- Total freedom of X-ray viewing angles
- Flexibility regarding size and shape of samples
- Air-coupled ultrasound scan of complex curvatures
- Extendible to 3D by Computed Tomography and Tomosythesis
- High resolution of 50 µm in large area scans
- Online and real time inspection
- Automatic repetitive inspection
- Easy programming or intuitive manual handling using 3D Mouse Move
- Possibility to integrate into production lines or stand-alone flexible lab systems or portable systems
Industrial fully digital X-ray imaging systems and CT machines have limits on sample size.

Easy real time inspection with3D MOUSE MOVE
3D Mouse Move is a plugin for SpaceMouse that allows controlling
the systems collaborative arms in real time and in any arbitrary
direction or rotation. Simply, once you shift and tilt the
SpaceMouse, the robot tool will follow the same tilt and shift.
Users position the robots are out of the operator‘s reach, 3D
Mouse Move replicates the same intuitive experience. Such cases
happen if the robots are inside another room or within inaccessible
areas by the operator, which is the case for RIS due to radiation
safety. 3D Mouse Move can be used to teach the robots during
programming or controlling them real-time to perform tasks.
