The document describes a radiation treatment planning system that uses established dose calculation algorithms, including Monte Carlo, but does not mention or imply the use of AI or ML for any function.
No.
The device is a treatment planning system that calculates and displays radiation dose distributions, assisting in the creation of treatment plans. It does not directly provide a therapeutic effect to the patient.
No
The device is used to create treatment plans and calculate radiation dose distributions, not to diagnose a disease. It takes diagnostic imaging data as input but does not produce a diagnosis itself.
Yes
The device description focuses entirely on the software's functionality for treatment planning, dose calculation, and data processing. It accepts data from external sources (imaging, dosimetry) and outputs treatment plans and dose distributions. There is no mention of any integrated hardware component that is part of the device itself. The submission addresses the addition of a new software algorithm.
Based on the provided information, the XiO RTP System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: An IVD device is defined as a medical device that is used to perform tests on samples such as blood, urine, or tissue to detect diseases or other conditions. These tests are performed outside of the body (in vitro).
- XiO RTP System Function: The XiO RTP System is a radiation treatment planning system. Its primary function is to:
- Accept patient imaging data and source dosimetry data.
- Allow users to define target volumes and critical structures.
- Calculate and display radiation dose distributions within the patient's body.
- Assist clinical personnel in selecting an appropriate treatment plan.
- No Sample Testing: The description of the XiO RTP System does not mention any testing of biological samples (blood, urine, tissue, etc.). It processes imaging data and radiation source data to plan treatment, which is an in vivo (within the body) process, even though the planning itself is done on a computer.
Therefore, the XiO RTP System falls under the category of a medical device used for treatment planning, but not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The XiO RTP System is used to create treatment plans for any cancer patient for whom external beam radiation therapy or brachytherapy has been prescribed. The system will calculate and display, both on-screen and in hard-copy, either two- or three-dimensional radiation dose distributions within a patient for a given treatment plan set-up.

Device Description
The XiO Radiation Treatment Planning system accepts a) patient diagnostic imaging data from CT and MR scans, or from films, and b) "source" dosimetry data, typically from a linear accelerator. The system then permits the user to display and define (contour) the target volume, which is the structure to be treated, and critical structures, or organs-atrisk, to which radiation dose must be limited.
Based on the dose prescribed, the user, typically a Dosimetrist or Medical Physicist, can then create multiple treatment scenarios involving the type, number, position(s) and energy of radiation beams and the use of treatment aids between the source of radiation and the patient (wedges, blocks, ports, etc.). The XiO system produces a display of radiation dose distribution within the patient, indicating doses to the target volume and critical structures. Appropriate clinical personnel select the plan that they believe most effectively maximizes dose to the target volume while minimizing dose to critical structures. The parameters of the plan are output in hard-copy format for later reference placed in the patient file.
This Premarket Notification addresses the addition of the Electron Monte Carlo dose calculation algorithm. XiO provides the user with the ability to choose between multiple dose calculation algorithms, selecting the algorithm most appropriate for the given clinical scenario. More accurate dose computation increases the probability that disease will be effectively treated and decreases the probability of undesirable side effects. No algorithm produces a perfectly accurate description of dose distribution; all algorithms have limitations, which are generally well understood and documented in scientific literature.
The addition of the Monte Carlo dose calculation algorithm gives users a new option for electron treatment plans. The algorithm represents the state of the art in radiation treatment planning and is widely recognized as the most accurate method currently available for computing the dose delivered by a beam of high-energý electrons.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical trials were not performed as part of the development 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. Algorithm testing was performed to compare calculated against measured doses to ensure dose calculation accuracy. In addition, clinically oriented validation test cases were written and executed in-house by CMS customer support personnel. The product was deemed fit for clinical use.

XIO INTENDED USE
The XiO RTP System is used to create treatment plans for any cancer patient for whom external beam radiation therapy or brachytherapy has been prescribed. The system will calculate and display, both on-screen and in hard-copy, either two- or three-dimensional radiation dose distributions within a patient for a given treatment plan set-up.

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 ... " XiO 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 XiO software and the linear accelerator. However, should a flaw in the treatment plan escape the notice of the qualified professionals using the XiO system, serious injury or death could result. Therefore, we believe XiO to be of major level of concern.

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.
