Leo Cancer Care Receives CE Mark for Upright Radiotherapy System Marie

May 22, 2026
Leo Cancer Care has secured CE marking for its Marie upright radiotherapy system, allowing commercial use across Europe. The system enables patients to receive treatment while seated or standing, and installations have begun at CNAO in Italy.

Leo Cancer Care has received CE marking for its Marie upright radiotherapy system, announced in a press release. The certification permits commercial deployment across Europe, bringing upright radiotherapy into clinical practice after gaining experience in the United States.

Marie enables patients to receive radiotherapy in an upright position rather than lying flat, aiming to simplify treatment room design and improve workflow efficiency. The system is compatible with multiple particle therapy modalities and supports adaptive and arc therapy.

Following the approval, Leo Cancer Care is expanding its collaboration with Centre Léon Bérard in France to study anatomical imaging and positioning in the upright orientation. The first European installation is underway at the Centro Nazionale di Adroterapia Oncologica (CNAO) in Italy, with treatments expected to begin before the end of the year.

The company is also working with other cancer centers across Europe to introduce the technology, which is designed to improve treatment precision and patient comfort.

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
