The description mentions "automatic software fiducial location" and a "software component that reads the patient's Computed Tomography (CT) imaging series and determines the coordinate system of the patient within the fiducial frame." While this involves image processing and automation, there is no mention of AI, ML, deep learning, or any related concepts, nor are there descriptions of training or test sets typically associated with AI/ML development. The focus is on a deterministic software process for fiducial localization.
No
The device is used for patient fixation and stereotactic localization during radiation therapy and radiosurgery, which are therapeutic procedures. However, the device itself does not directly deliver the therapy nor does it have an active therapeutic effect; it is an accessory used in the delivery of therapy.
No
The device is used for patient fixation and stereotactic localization during radiation therapy and radiosurgery, not for diagnosing a disease or condition.
No
The device description explicitly states that the device is comprised of both hardware and software components, including a Dental Tray, head and neck support, and a Stereotactic Fiducial Frame.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: This device is used for external beam stereotactic radiation therapy and radiosurgery. Its primary function is patient fixation and stereotactic localization during imaging (CT) and treatment delivery. It works directly with the patient's body and imaging data, not with in vitro specimens.
- Intended Use: The intended use clearly states it's for patients requiring radiation therapy and radiosurgery, focusing on physical positioning and localization.
- Device Description: The description details hardware (dental tray, head and neck support, fiducial frame) and software components that interact with the patient and imaging data for localization and fixation. There is no mention of analyzing biological samples.
Therefore, this device falls under the category of a medical device used for treatment planning and delivery, not an in vitro diagnostic device.

Intended Use / Indications for Use
This product is used for patients who require external beam stereotactic radiation therapy of the head and neck region or radiosurgery of the cranial region. The system provides cranial and head and neck fixation and stereotactic localization with automatic software fiducial localization. It is intended to be used during both Computed Tomography (acquisition of the imaging series used for the patient's treatment plan) and each of the patient radiation treatments.

Device Description
The Aktina Head and Neck Stereotactic Localizer, Part Number 50-100, is used for the localization and fixation of patients undergoing stereotactic radiotherapy and radiosurgery of the cranial area, as well as radiotherapy of the head and neck area. Fixation is accomplished via two components: a customized Dental Tray that with the aid of slight vacuum suction fixes to the roof of the patient's mouth, and a customized head and neck support. Localization is accomplished via two components: a hardware component which comprises of a Stereotactic Fiducial Frame that is positioned over the patient's treatment area while being accurately interfaced to the Dental Tray, and a software component that reads the patient's Computed Tomography (CT) imaging series and determines the coordinate system of the patient within the fiducial frame. The Fiducial Frames are used during the patient's initial CT and then as a setup target box for each treatment thereafter.
The following are optional components of the system:
- . shoulder restraints which can be employed for head and neck treatments,
- . a table adapter which allows for manual angulations to level the system within the treatment room in order to remove any angular errors induced by the treatment couch,
- . a software tool that rotates the patient's imaging series (used for treatment planning) to remove any angular errors incurred during the initial CT imaging.
