Intended Use

ExacTrac Dynamic is intended to position patients at an accurately defined point within the treatment beam of a medical accelerator for stereotactic radiosurgery or radiotherapy procedures, to monitor the patient position and to provide a beam hold signal in case of a deviation in order to treat lesions, tumors and conditions anywhere in the body when radiation treatment is indicated.

Device Story

ExacTrac Dynamic (ETD) is an add-on system for linear accelerators (linacs) used in radiotherapy. It inputs patient CT data and treatment plans; uses thermal-surface cameras and oblique X-ray imaging to determine patient position relative to the planned treatment beam. The system calculates correction shifts for the linac to align the patient. During treatment, it monitors patient position via surface tracking and X-ray to detect movement; provides a beam-hold signal to the linac if deviations occur. Supports breath-hold workflows for respiratory motion management. ExacTrac Dynamic Surface (ETDS) is a camera-only configuration for surface-based monitoring, requiring external IGRT (e.g., CBCT). Operated by clinicians in a radiotherapy environment. Output allows precise patient alignment and real-time monitoring, reducing respiratory-induced tumor motion and protecting organs at risk. Benefits include improved treatment accuracy and safety.

Clinical Evidence

No clinical data. Bench testing only; software verification and validation conducted per FDA guidance for enhanced level documentation.

Technological Characteristics

Add-on system for linacs. Components: thermal-surface camera, workstation, interconnection hardware, optional X-ray imaging (ETD) or camera-only (ETDS). Connectivity: NEMA gating interface for beam hold/stop (Varian and Elekta). Software-based positioning and monitoring. No specific material standards cited.

Indications for Use

Indicated for patients requiring stereotactic radiosurgery or radiotherapy for lesions, tumors, and conditions anywhere in the body. Used for patient positioning, monitoring, and respiratory motion management (breath-hold) during radiation treatment.

## 1. Indications for Use

ExacTrac Dynamic is intended to position patients at an accurately defined point within the treatment beam of a medical accelerator for stereotactic radiosurgery or radiotherapy procedures, to monitor the patient position and to provide a beam hold signal in case of a deviation in order to treat lesions, tumors and conditions anywhere in the body when radiation treatment is indicated.

## 2. Device Description

ExacTrac Dynamic (ETD) is a patient positioning and monitoring device used in a radiotherapy environment as an add-on system to standard linear accelerators (linacs). It uses radiotherapy treatment plans and the associated computed tomography (CT) data to determine the patient's planned position and compares it via oblique X-ray images to the actual patient position. The calculated correction shift will then be transferred to the treatment machine to align the patient correctly at the machine's treatment position. During treatment, the patient is monitored with a thermal-surface camera and X-ray imaging to

ensure that there is no misalignment due to patient movement. Positioning and monitoring are also possible in combination with implanted markers. By defining the marker positions, ExacTrac Dynamic can position the patient by using X-rays and thereafter monitor the position during treatment.

Additionally, ExacTrac Dynamic features a breath-hold (BH) functionality to serve as a tool to assist respiratory motion management. This functionality includes special features and workflows to correctly position the patient at a BH level and thereafter monitor this position using surface tracking. Regardless of the treatment indication, a correlation between the patient's surface and internal anatomy must be evaluated with Image-Guided Radiation Therapy. The manually acquired X-ray images support a visual inspection of organs at risk (OARs). The aim of this technique is to treat the patient only during breath hold phases where the treatment target is at a certain position to reduce respiratory-induced tumor motion and to ensure a certain planned distance to OARs such as the heart. In addition to the X-ray based positioning technique, the system can also monitor the patient after external devices such as Cone-Beam CT (CBCT has been used to position the patient).

The ExacTrac Dynamic Surface (ETDS) is a camera-only platform without the X-ray system and is available as a configuration which enables surface-based patient monitoring. This system includes an identical thermal-surface camera, workstation, and interconnection hardware to the linac as the ETD system. The workflows supported by ETDS are surface based only and must be combined with an external IGRT device (e.g., CBCT).

3. Substantial Equivalence

For the Substantial Equivalence determination, comparison of the Subject Device features with the following predicate device(s) was carried out:

K240431; ExacTrac Dynamic 2.0

The predicate was chosen since it's the predecessor version and similar to the subject device with respect to the indications for use, technological characteristics and use cases.

The main difference between the Subject and the Predicate device is a third digit version update to 2.0.2 to be compliant with the updated 3rd party Linac from Elekta with Integrated Gating (NEMA) interface) which resulted in the update of specifications and risk profile.
