The document describes a radiation treatment planning system that uses established methods for dose calculation and plan optimization. There is no mention of AI or ML in the intended use, device description, or performance studies. The optimization process described appears to be based on traditional algorithms rather than machine learning.
No
The device is a radiation treatment planning system that calculates and displays radiation dose distributions, but it does not directly administer treatment.
No.
Explanation: The device is a radiation treatment planning system that calculates and displays radiation dose distributions for therapy, rather than diagnosing a condition.
No
The device description explicitly mentions accepting "source" dosimetry data from a linear accelerator and the withdrawal of a previous 510(k) because "there was no hardware cleared for the US market capable of delivering carbon ion plans." This indicates a dependency on and interaction with hardware components (linear accelerators) for its intended use, even if the device itself is primarily software.
Based on the provided text, the Monaco system is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD Definition: In vitro diagnostic devices are used to examine specimens derived from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Monaco's Function: The Monaco system is a radiation treatment planning system. Its purpose is to calculate and display radiation dose distributions within a patient's body based on imaging data and treatment parameters. It does not analyze biological specimens.
- Intended Use: The intended use is explicitly stated as "radiation treatment planning," which is a process performed on the patient's body (or a representation of it) rather than on a sample taken from the body.
Therefore, the Monaco system falls under the category of medical devices used for treatment planning, not in vitro diagnostics.
N/A
Intended Use / Indications for Use
The Monaco system is used to make treatment plans for patients with prescriptions for external beam radiation therapy. The system calculates dose for photon and electron treatment plans and displays, on-screen and in hard-copy, two- or three-dimensional radiation dose distributions inside patients for given treatment plan set-ups.
The Monaco product line is intended for use in radiation treatment planning. It uses generally accepted methods for:
- contouring
- image manipulation
- simulation

Device Description
Monaco is a radiation treatment planning system that first received FDA clearance in 2007 (K071938). The modified system received clearance in 2009, when Volumetric Modulated Arc Therapy (VMAT) planning capability was added (K091179), again when Dynamic Conformal Arc planning was added (K110730), and electron planning, support for stereotactic cones, and SUV calculation were added (K132971). Finally, specialty image creation was added in 2015 (K15123). A 510(k) was filed in 2017 for the addition of carbon ion planning. The 510(k) was withdrawn because there was no hardware cleared for the US market capable of delivering carbon ion plans. Monaco's carbon ion planning functionality remains licensed off and inaccessible to US users.
Since the 2015 510(k) clearance, IMPAC Medical Systems, Inc. merged with Elekta, Inc., both wholly owned subsidiaries of Elekta AB. There were no changes in location, personnel, or quality system as a result of the merger. However, the name of the manufacturer for Monaco as changed from IMPAC Medical Systems, Inc, to Elekta, Inc.
The Monaco system accepts patient imaging data and "source" dosimetry data from a linear accelerator. The system then permits the user to display and define (contour) the target volume to be treated and critical structures which must not receive above a certain level of radiation on these diagnostic images.
Based on the prescribed dose, the user, a Dosimetrist or Medical Physicist, can create multiple treatment scenarios involving the number, position(s) and energy of radiation beams and the use of a beam modifier (MLC, block, etc.) between the source of radiation and the patient to shape the beam. The Monaco system then produces a display of radiation dose distribution within the patient, indicating doses to the target volume and surrounding structures. The "best" plan satisfying the clinican prescription is then selected, one that maximizes dose to the target volume while minimizing dose to surrounding healthy volumes.

PREDICATE DEVICE INFORMATION
The Monaco RTP System is substantially equivalent to the following devices that the Food and Drug Administration (FDA) has cleared for distribution and are currently being actively marketed in the United States. Monaco is substantially equivalent to these products in intended use and safety and effectiveness.
MONACO INTENDED USE/INDICATIONS FOR USE
The Monaco system is used to make treatment plans for patients with prescriptions for external beam radiation therapy. The system calculates dose for photon and electron treatment plans and displays, on-screen and in hard-copy, two- or three-dimensional radiation dose distributions inside patients for given treatment plan set-ups.
The Monaco product line is intended for use in radiation treatment planning. It uses generally accepted methods for:
- · contouring
- · image manipulation
- · simulation
- · image fusion
- · plan optimization
- · QA and plan review
DESCRIPTION OF THE PRODUCT
Monaco is a radiation treatment planning system that first received FDA clearance in 2007 (K071938). The modified system received clearance in 2009, when Volumetric Modulated Arc Therapy (VMAT) planning capability was added (K091179), aqain when Dynamic Conformal Arc planning was added (K110730), and electron planning, support for stereotactic cones, and SUV calculation were added (K132971). Finally, specialty image creation was added in 2015 (K15123). A 510(k) was filed in 2017 for the addition of carbon ion planning. The 510(k) was withdrawn because there was no hardware cleared for the US market capable of delivering carbon ion plans. Monaco's carbon ion planning functionality remains licensed off and inaccessible to US users.
Since the 2015 510(k) clearance, IMPAC Medical Systems, Inc. merged with Elekta, Inc., both wholly owned subsidiaries of Elekta AB. There were no changes in location, personnel, or quality system as a result of the merger. However, the name of the manufacturer for Monaco as changed from IMPAC Medical Systems, Inc, to Elekta, Inc.

The Monaco system accepts patient imaging data and "source" dosimetry data from a linear accelerator. The system then permits the user to display and define (contour) the target volume to be treated and critical structures which must not receive above a certain level of radiation on these diagnostic images.
Based on the prescribed dose, the user, a Dosimetrist or Medical Physicist, can create multiple treatment scenarios involving the number, position(s) and energy of radiation beams and the use of a beam modifier (MLC, block, etc.) between the source of radiation and the patient to shape the beam. The Monaco system then produces a display of radiation dose distribution within the patient, indicating doses to the target volume and surrounding structures. The "best" plan satisfying the clinican prescription is then selected, one that maximizes dose to the target volume while minimizing dose to surrounding healthy volumes.
LEVEL OF CONCERN
Item 4b of Table 1 in the FDA Guidance document entitled, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices asks, "Does the Software Device control the delivery of potentially harmful energy that could result in death or serious injury, such as radiation treatment systems…." Monaco does not directly control the linear accelerator that delivers the radiation. Once completed, plans are reviewed and approved by qualified clinicians and may be subject to quality assurance practices before treatment actually takes place. There is no automatic link between the Monaco software and the linear accelerator. However, should a flaw in the treatment plan escape the notice of the qualified professionals using the Monaco system, serious injury or death could result. Therefore, we believe Monaco to be of major level of concern.
SUMMARY OF CLINICAL TESTING
Clinical trials were not performed as part of this product. Clinical testing on patients is not advantageous in demonstrating substantial equivalence or safety and effectiveness of the device since testing can be performed such that no human subjects are exposed to risk. Validation testing involved simulated clinical workflows using actual patient data, such as patient images, described in detail in section 20. Algorithm testing verified the accuracy of the new dose calculation algorithm in Monaco 5.40 using the same test methods as the predicate version of Monaco. Pre-defined passifail criteria were also equivalent to that of the predicate, K151233. Equivalent accuracy was demonstrated, and the product was deemed substantially equivalent and fit for clinical use.
SUMMARY OF NON-CLINICAL TESTING
Verification tests were written and executed to ensure that the system is working as designed. Over 600 test procedures were executed, including tests to verify requirements for new product functionality, tests to ensure that risk mitigations function as intended, and regression tests to ensure continued safety and effectiveness of existing functionality. Verification testing was performed according to the FDA Quality System Regulation (21 CFR §820), ISO 13485 Quality Management System standard, IEC 62304 Software Life Cycle standard, and ISO 14971 Risk Management Standard, as was the predicate version, K151233. Quality System procedures goverening the testing process, including pre-defined pass/fail criteria, were equivalent to procedures used in the testing of the previous Monaco version cleared under K151233. Conformity to the same passifail criteria as the predicated that Monaco 5.40 was substantially equivalent in safety and effectiveness. Monaco 5.40 was deemed safe and effective for its intended use.
