## Indications for Use

It is intended for use in the planning and conduct of 3 dimensional radiation therapy with a linear accelerator.

## Device Story

Stereotactic Body Frame is an external spatial reference system for patient positioning during radiotherapy. It consists of a base plate connected to the patient via a thermoconformable mask or cushion and secured to a linear accelerator (LINAC) couch. The device uses copper indicators to determine target coordinates on CT scans, allowing spatial registration between diagnostic images and the treatment plan. It enables precise patient fixation and localization for stereotactic radiosurgery (SRS) or stereotactic radiotherapy (SRT). Clinicians use the system to reproduce target coordinates, ensuring accurate radiation delivery to tumoral lesions. The device benefits patients by facilitating 3D radiation therapy planning and conduct.

## Clinical Evidence

Bench testing only.

## Technological Characteristics

Materials: Carbon-fiber and plexiglass. Sensing/Actuation: Spatial reference system using copper indicators for coordinate determination. Connectivity: Compatible with ERGO-SCT software. Form factor: Base plate with fixation accessories (mask/cushion).

## Regulatory Identification

A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.
