Simulation for Design

The first step for any project of realizing any device or even a full facility is a good realistic design of it, thanks to which it's possible to spare time, effort and money as well.

Ripple Filters

The main problem dealing with protons or carbon ions beam therapy is the need to deliver a uniform dose with a minimum of energy steps.
I-See designed particular components, called Ripple Filters, that are able to spread around the Bragg peak preserving its gaussian shape.

Ripple filters designed have a triangular section and they are made of PMMA. Their effect on the beam depends on the scattering and the struggling process that affect different particles types.

Protons have higher scattering and struggling effects than carbon ions.
The effect of a single ripple filter on a protons beam is stronger for low kinetic energies (< 100 MeV) and the filter shape is slightly influent. The use of a second filter on the exit window allows to obtain a better approximation of the gaussian profile. For high energies (> 200 MeV) peak broadening and dose uniformity are no more dependent on the filter like for the low energies case.

The scattering effect on carbon ions is very small and the triangular profile is not able to produce a regular gaussian shape. A single ripple filter is not able to give significant while with the use of a double filter, where the second one is located at the exit window, it is possible to well approximate the gaussian shape. This configuration allows to reduce the distance between the last ripple filter and the treated volume.


Anthropomorphic virtual phantoms are instruments widely used in nuclear medicine and radioprotection fields. In particular, CT images coming from anthropomorphic virtual patients are used instead of the real ones for the validation and optimisation of TPSs. Virtual phantoms are also used in radiopharmaceutical field because it is possible to simulate the substance path inside the human body and the resulting deposited dose in human healthy tissues.

VPatient3D is our product that has been designed starting from MASH supine model. Organs dimensions and position are modelled according to the ICRP Report 110; materials densities and compositions are also based on ICRP recommendations.


This is a really critical phase for validating and getting permission to use a specific device or more a full facility, that needs a well benchmarked information to fulfill the requirements for using it. Our efficient solutions can speed up the process and identify any potential anomalies during the first runs.
