The document describes a radiation therapy system with integrated planning, dose calculation, and imaging. It details the hardware components and the workflow but does not mention any AI or ML algorithms used for planning, image analysis, or treatment delivery. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".
Yes
The device is described as an integrated system for the planning and delivery of intensity modulated radiation therapy (IMRT) for the treatment of cancer, which directly indicates a therapeutic function.
No
The device is intended for planning and delivery of radiation therapy, and it explicitly states that the TomoImage (MVCT image) used for patient positioning is "not for diagnostic use." While it imports diagnostic CT images, it is not performing diagnostic functions itself.
No
The device description clearly outlines significant hardware components, including a linear accelerator, gantry, multi-leaf collimator (MLC), detector, control devices, and power supplies, all integrated into a physical system for delivering radiation therapy. While software is involved in planning and control, it is not a standalone software-only device.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens from the human body. The TomoTherapy HI-ART System is a radiation therapy system that directly treats patients with radiation. It does not analyze biological samples like blood, urine, or tissue.
- The intended use is for planning and delivering radiation therapy. The primary function is therapeutic, not diagnostic analysis of biological specimens.
- The imaging capabilities (Diagnostic CT import and MVCT) are for treatment planning and patient positioning. While imaging is involved, it's for guiding the radiation delivery, not for diagnosing disease from biological samples. The description explicitly states the MVCT image is "not for diagnostic use."
Therefore, the TomoTherapy HI-ART System falls under the category of a therapeutic medical device, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The TomoTherapy HI-ART System is intended to be used as an integrated system for the planning and delivery of intensity modulated radiation therapy (IMRT) for the treatment of cancer. The HI-ART System provides precise delivery of radiation to tumors while minimizing the delivery of radiation to vital healthy tissue.
The HI-ART System's planning station is intended to be used by the physician/oncologist to prescribe a radiation therapy plan for a particular patient. The HI-ART System then calculates the treatment plan which the physician reviews and approves.
The HI-ART system's operator station and status console is then intended to be used by the therapist to select and implement the patient's treatment plan. The treatment process will begin by performing a TomoImage™ (MVCT) scan (a CT using the onboard linear accelerator as the radiation source). This TomoImage (MVCT) will confirm that the patient's position is correct for the radiation therapy as well as assist in patient re-positioning when necessary. The TomoImage (MVCT image) is not for diagnostic use.
When patient positioning is complete, the HI-ART System is then intended to be used by the therapist to treat the patient using the selected treatment plan. The HI-ART System delivers the radiation therapy, or stereotactic radiotherapy or radiosurgery, treatment in accordance with the physician approved plan using IMRT techniques delivered in a helical tomographic pattern.

Device Description
The TomoTherapy HI-ART System is a radiation therapy system that integrates planning, dose calculation, megavoltage CT scanning, and helical radiation therapy treatment capabilities into a single comprehensive IMRT system.
The HI-ART System's planning station is used by the physician to prescribe and enter the radiation therapy plan. The patient's diagnostic CT image is imported via a DICOM protocol from another diagnostic CT device. The regions of interest, regions to avoid, and other prescribing information are entered in a manner that is similar to other commercially available planning systems.
The HI-ART System utilizes a 6 MV linear accelerator as the radiation source. The linear accelerator along with the primary collimator, multi-leaf collimator (MLC), detector, various control devices and power supplies are mounted on a rotating gantry. much like a CT gantry. During treatment or imaging, the patient is positioned on the couch support, and the couch moves axially through the bore of the gantry, and the radiation is delivered in a helical pattern.
The primary collimator and the MLC control the beam dimensions during radiation delivery so that the range of collimated beam size can vary from 0 to 400 mm wide by 5 to 50 mm at the isocenter. The MLC is constructed of 64 tungsten leaves that open and close as determined by the radiation therapy plan. The intensity of the radiation beam is proportional to the length of time that a particular leaf is open. The opening and closing of various leaves as the radiation is delivered in this helical pattern allows for an IMRT plan to be delivered with precise control. The result is a highly conformal dose to the region of interest with low doses to surrounding healthy tissue.
Because the HI-ART System is operating in a helical mode similar to CT systems, it inherently has the ability to obtain a CT image. The system utilizes the linear accelerator to obtain a megavoltage (MVCT) scan of the region of interest prior to the delivery of radiation therapy. This MVCT image is then used to ascertain that the patient is correctly positioned prior to treatment. The radiation dose to the patient from an MVCT scan is comparable to diagnostic CT or portal imaging.

DESCRIPTION
(page 2/3)
The TomoTherapy HI-ART System is a radiation therapy system that integrates planning, dose calculation, megavoltage CT scanning, and helical radiation therapy treatment capabilities into a single comprehensive IMRT system.
The HI-ART System's planning station is used by the physician to prescribe and enter the radiation therapy plan. The patient's diagnostic CT image is imported via a DICOM protocol from another diagnostic CT device. The regions of interest, regions to avoid, and other prescribing information are entered in a manner that is similar to other commercially available planning systems.
The HI-ART System utilizes a 6 MV linear accelerator as the radiation source. The linear accelerator along with the primary collimator, multi-leaf collimator (MLC), detector, various control devices and power supplies are mounted on a rotating gantry. much like a CT gantry. During treatment or imaging, the patient is positioned on the couch support, and the couch moves axially through the bore of the gantry, and the radiation is delivered in a helical pattern.
The primary collimator and the MLC control the beam dimensions during radiation delivery so that the range of collimated beam size can vary from 0 to 400 mm wide by 5 to 50 mm at the isocenter. The MLC is constructed of 64 tungsten leaves that open and close as determined by the radiation therapy plan. The intensity of the radiation beam is proportional to the length of time that a particular leaf is open. The opening and closing of various leaves as the radiation is delivered in this helical pattern allows for an IMRT plan to be delivered with precise control. The result is a highly conformal dose to the region of interest with low doses to surrounding healthy tissue.
Because the HI-ART System is operating in a helical mode similar to CT systems, it inherently has the ability to obtain a CT image. The system utilizes the linear accelerator to obtain a megavoltage (MVCT) scan of the region of interest prior to the delivery of radiation therapy. This MVCT image is then used to ascertain that the patient is correctly positioned prior to treatment. The radiation dose to the patient from an MVCT scan is comparable to diagnostic CT or portal imaging.
SAFETY CONSIDERATIONS
The HI-ART System has several characteristics that promote its safety - no beam blocks are used that can fall off onto the patient; the rotating gantry is covered so that the patient cannot contact moving gantry parts; the linear accelerator operates in photon mode only so inadvertent electron exposure is virtually eliminated; MVCT allows for reliable patient positioning.
Also, the HI-ART System consists of components similar to those already commercially marketed, including the 6 MV linear accelerator, rotating gantry, patient couch and CT imaging devices.
STANDARDS COMPLIANCE
The HI-ART System is designed to comply with relevant sections of the IEC 60601-1, IEC 60601-2-1, IEC 60601-1-2, IEC 60601-1-4 safety standards.
