Indications for Use
The TomoTherapy Treatment System is intended to be used as an integrated system for the planning and precise delivery of radiation therapy, stereotactic radiotherapy, or stereotactic radiosurgery to tumors or other targeted tissues while minimizing the delivery of radiation to vital healthy tissue. The megavoltage x-ray radiation is delivered in a rotational, non-rotational, modulated (IMRT), or non-modulated (non-IMRT/three dimensional conformal) format in accordance with the physician approved plan.
Device Story
TomoTherapy Treatment System integrates radiation therapy planning, dose calculation, and megavoltage CT imaging for IGRT; delivers rotational/fixed-beam radiation. Modification (Fast Optimizer) adds GPU hardware and revised software to accelerate treatment planning and dose calculation. System is prescription-only; operated by clinical staff in radiation oncology settings. Device does not diagnose or recommend treatment; provides output based on physician-approved plans. Benefits include precise radiation delivery to tumors while sparing healthy tissue; increased efficiency in planning workflow.
Clinical Evidence
Bench testing only. Verification and validation tests confirmed performance is within design specifications and meets applicable consensus standards. No clinical tests were required.
Technological Characteristics
Radiation therapy system with integrated planning, dose calculation, and MV CT imaging. Modification adds GPU hardware for accelerated optimization and dose calculation. Energy source: megavoltage x-ray. Connectivity: integrated system. Software: revised for GPU-based optimization. Sterilization: N/A (not applicable to system hardware).
Indications for Use
Indicated for patients requiring radiation therapy, stereotactic radiotherapy, or stereotactic radiosurgery for tumors or other targeted tissues. Used for delivery of megavoltage x-ray radiation in rotational, non-rotational, modulated (IMRT), or non-modulated formats per physician-approved plan.
Regulatory Classification
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.

#### Predicate Device:
TomoTherapy Hi-Art System (modified) K082005
#### Description:
The TomoTherapy Treatment System is a radiation therapy system that integrates planning, dose calculation, megavoltage CT imaging for IGRT functionality, and helical (rotational) and fixed beam (non-rotational) radiation therapy treatment capabilities into a single comprehensive system.
The TomoTherapy Treatment System is a prescription device. It delivers radiation in accordance with a physician approved plan. The device does not diagnose disease, recommend treatment regimens, or quantify treatment effectiveness. The megavoltage CT imaging functionality is not intended for diagnostic use.
The TomoTherapy Treatment System with Fast Optimizer is a modification that allows for increased efficiency and speed during the treatment planning process through the use of modified hardware and software. The device name remains unchanged as "TomoTherapy Treatment System", and the modification itself is referred to as TomoTherapy Treatment System Fast Optimizer.
#### Intended Use:
The TomoTherapy Treatment System is intended to be used as an integrated system for the planning and precise delivery of radiation therapy, stereotactic radiotherapy, or stereotactic radiosurgery to tumors or other targeted tissues while minimizing the delivery of radiation to vital healthy tissue. The megavoltage x-ray radiation is

delivered in a rotational, non-rotational, modulated (IMRT), or non-modulated (non-IMRT/three dimensional conformal) format in accordance with the physician approved plan.
#### Technological Characteristics:
The technological characteristics of the TomoTherapy Treatment System Next Generation Fast Optimizer are substantially equivalent to the predicate. The TomoTherapy Treatment System Next Generation Fast Optimizer introduces new hardware, a Graphics Processing Unit (GPU), and revised software to accommodate this new hardware to allow for substantially increased speed and efficiency during the performance of optimization and dose calculation processes. All other primary subassemblies remain unchanged, and therefore this modification is comparable in key safety and effectiveness features, utilizes substantially similar design, construction, materials, energies, and it has an intended use that is identical to that of the predicate device.
As the modification is limited to faster operation of the Planning sub-system with unchanged dose accuracy constraints, and the changes do not affect the radiation delivery system, this modification does not alter the performance claims for the product. These technological enhancements do not raise new types of safety or effectiveness questions.
### Performance Data:
The TomoTherapy Treatment System Next Generation Fast Optimizer was tested and it was demonstrated that there are no changes to the conformance to the requirements of applicable recognized consensus standards for medical devices. Results of verification and validation tests confirm the TomoTherapy Treatment System Next Generation Fast Optimizer performance is within design specifications. No clinical tests were required to establish substantial equivalence. These performance data demonstrate the TomoTherapy Treatment System Next Generation Fast Optimizer is as safe, as effective, and performs as well as the predicate device.
#### Summary:
The TomoTherapy Treatment System Next Generation Fast Optimizer is substantially equivalent to the predicate device. The intended use, major technological characteristics, and principles of operation of the TomoTherapy Treatment System Fast Optimizer are identical to those of the predicate device. Minor technological differences do not raise new types of safety or effectiveness questions. Performance data demonstrate the TomoTherapy Treatment System Fast Optimizer is as safe, as effective, and performs as well as the predicate device.
