# Beams

IF WE remove more of the patients’ tumors during surgery, CAN WE extend their life expectancy and reduce their risk of recurrence?

Challenge

The *Beams* project was initiated to address a major challenge in oncological surgery: improving the definition of tumor margins during surgical interventions. A concrete case illustrates this difficulty—a 44-year-old patient suffering from a brain tumor located near vital functional areas. To avoid damaging these critical structures while removing as much of the tumor as possible, surgeons often face significant obstacles. This challenge directly inspired neurosurgeon and co-founder, Professor Stéphane Palfi, who has encountered this clinical dilemma firsthand. *Beams'* primary goal is to develop innovative solutions that help surgeons achieve complete tumor removal while preserving essential functions.

Disruptive Innovation

The key innovation of *Beams* lies in the development of *TRIOP*, a miniaturized intraoperative probe capable of detecting tumor tissues in real time. This technology uses beta radiation detection through specialized tracers, enabling surgeons to identify tumor margins with millimetric precision. This greatly improves the accuracy of surgical procedures, allowing for maximal tumor removal while protecting healthy structures. Compared to traditional methods like fluorescence, *TRIOP* represents a paradigm shift, with potential applications for all types of cancer. *Beams* aims to bring this technology to market by 2028.

BEAMS SDGs

Impact

*Beams* could have a significant impact on cancer patients. The *TRIOP* technology would enable more complete tumor resections, reducing the risk of recurrence and potentially prolonging patient survival. This could also have positive economic implications by decreasing the need for reoperations, contributing to a more sustainable healthcare system. *Beams* aligns with the United Nations Sustainable Development Goals by adopting eco-responsible manufacturing processes, emphasizing local sourcing, and utilizing energy-efficient technologies.

Leveraging the 3DEXPERIENCE Platform

*Beams* plans to leverage the **3D**EXPERIENCE platform to optimize its innovation process. The platform offers tools for design, simulation, and regulatory compliance, facilitating the smooth transition from concept to clinical preparation.

The unified environment of **3D**EXPERIENCE promotes collaboration among engineers, researchers, and medical experts, speeding up product development. *Beams*' CEO, Virginie Simon, has highlighted her extensive experience with Dassault Systèmes' tools.

Collaboration & Collective Intelligence

*Beams* was founded by a multidisciplinary and complementary team, including Virginie Simon (CEO with over 15 years of entrepreneurial experience), Professor Stéphane Palfi (neurosurgeon and *TRIOP* pioneer), Laurent Ménard (nuclear medical imaging researcher with over 20 years of experience), and Estelle Villedieu de Torcy (CTO). This team is supported by a scientific council, a strategic committee, and various consultants.

Their collaboration is key to accelerating progress, bolstered by tools like the **3D**EXPERIENCE platform. *Beams* has also secured an initial serie A and participates in events like VivaTech to strengthen its network within the innovation ecosystem.

Beams

Beams is a French medtech company founded in 2021. Its core ambition is to help surgeons better define tumor margins during cancer surgery. Beams develops TRIOP technology, which is a combination between a beta particle detector and a surgical aspirator.
