Phemto
Compact Proton Beam Therapy

A compact proton therapy system, engineered for integration into hospital sites. Siyasi Healthcare supports institutional clients from importation through to long-term maintenance.

System Architecture

From source to treatment, a single continuous beamline.

Injector & Beam Source

The particle beam originates at the injector stage before entering the acceleration beamline.

Bending Magnets

A sequence of magnets steers and shapes the beam path along the length of the system.

Rotating Gantry

The gantry directs the beam toward the patient positioning couch from the required angle.

Patient Positioning & Delivery

A robotic couch and respiratory-gating system support precise, repeatable patient positioning.

Why Phemto

A different approach to compact proton-therapy infrastructure.

Phemto is designed around a compact magnetic-gantry concept. The distinction is not a consumer-style product feature; it is an engineering and infrastructure conversation for hospitals planning how advanced particle therapy could fit into a real clinical environment.

Magnetic Gantry Concept

Manufacturer material describes a gantry system that uses electromagnets to change irradiation angle, rather than relying on the large conventional rotating-gantry architecture used by many particle-therapy systems.

Compact Building Envelope

The supplied B dot Medical material compares a 4m Phemto system height with a 12m conventional reference system and describes a reduced building footprint. For hospital planners, the relevant question is how advanced particle therapy can be considered within the constraints of site, structure, access, and capital planning.

Short Scanning Geometry

The manufacturer presentation describes a short source-axis-distance scanning configuration, designed to support compactness while maintaining precise beam-delivery architecture.

Workflow & Motion Management

Phemto materials describe a self-propelled treatment-table workflow, high-speed scanning, and respiratory-gating capability. These elements are relevant to treatment-room workflow, positioning, and the management of moving targets.

System In Motion

Real system footage, supplied by the manufacturer.

Magnetic Gantry

Rotational precision of the gantry assembly, positioning the beamline relative to the patient couch.

Robotic Positioning Couch

Multi-axis couch movement supporting fine patient positioning ahead of treatment delivery.

Respiratory-Gated Scanning

Scanning synchronized to respiratory motion, illustrating the system's approach to motion management.

Institutional Support

Supported through the full lifecycle of adoption.

Importation

Coordinated import of the system into the receiving country.

Regulatory Compliance

Support navigating the applicable regulatory pathway for the receiving institution.

Logistics & Site Preparation

Coordination with facilities and engineering teams ahead of delivery.

Installation & Commissioning

On-site installation and system commissioning ahead of clinical use.

Clinical & Technical Training

Training for clinical and technical staff operating the system.

Ongoing Maintenance

Continued technical support and maintenance coordination.
