Intended Use
XPlan-1 is a stereotactic LINAC-based radiation treatment planning system. XPlan-1 localizes lesions to be treated using CT scans, MR scans and digitized angiographic film. XPlan-1 provides a stereotactic planning system, for treatment of tumors < 7 cm in diameter at sites such as base of skull and head. The conformal stereotactic treatments are delivered over multiple fractions.
Device Description
The XPlan-1 system has the same intended use and similar technological characteristics as the commercially available XKnife-3 Stereotactic Radiation Treatment Planning System. Like XKnife-3, the XPlan-1 system includes the same image acquisition, localizing, contouring and beam planning techniques. In addition, XPlan-1 and XKnife-3 both contain methods of QA verification for targeting setup and delivery. XPlan-1 includes modifications of the XKnife-3 system, such as the ability to use conformal collimation devices and a modification to the dose algorithm to account for the use of conformal collimation devices. XPlan-1 also supports the use of the Laser Angio Target Localizer (LATL) as an additional QA check to verify the orientation and position of the LINAC jaws and gantry, the collimator and couch rotation. Like the XKnife-3 use of the Rectilinear Phantom Pointer (RLPP) and Laser Target Localizer Frame (LTLF), XPlan-1 supports the use of the LATL to confirm system alignment at isocenter and to position the patient at isocenter. XPlan-1 is also substantially equivalent to the commercially available Conformal Radiation Treatment Planning System, FOCUS. Like FOCUS, XPlan-1 supports the use of LINAC jaws, MLCs and wedges to modify the shape and attenuation of the beam. Both XPlan-1 and FOCUS also have the ability to model the total on the target volume and surrounding tissue via a 3D Beam's Eye View and 2D beam visualization. Both systems, also addition to the dose-volume histogram.

Not Found

No
The summary describes a traditional radiation treatment planning system with standard image processing, contouring, and dose calculation techniques. There is no mention of AI, ML, or related concepts.

No
XPlan-1 is a treatment planning system that localizes lesions and plans radiation treatments, but it does not directly deliver the therapy itself. It is a tool used in the planning phase of treatment.

No

The device is a treatment planning system for radiation therapy, which is used to plan the delivery of treatment rather than to diagnose a condition. It localizes lesions for treatment and plans the treatment delivery, using imaging data but not for diagnostic purposes.

No

The device description explicitly mentions supporting the use of hardware components like the Laser Angio Target Localizer (LATL) and referencing the use of the Rectilinear Phantom Pointer (RLPP) and Laser Target Localizer Frame (LTLF) in the predicate device comparison. While the core function is software-based planning, the system integrates with and relies on specific hardware for QA and patient positioning.

Based on the provided information, the XPlan-1 device is not an In Vitro Diagnostic (IVD).

Here's why:

  • Intended Use: The intended use clearly states that XPlan-1 is a "stereotactic LINAC-based radiation treatment planning system." Its purpose is to plan radiation therapy for lesions, not to perform tests on biological samples (like blood, urine, or tissue) to diagnose or monitor a disease or condition.
  • Device Description: The description focuses on image processing, localization, contouring, beam planning, and quality assurance for radiation delivery. These are all related to the physical delivery of radiation therapy, not in vitro testing.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any of the typical components or processes associated with IVD devices.

Therefore, XPlan-1 falls under the category of a medical device used for treatment planning, specifically in the field of radiation oncology, rather than an In Vitro Diagnostic device.

(a)
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.(b)
Classification. Class II. When intended for use as a quality control system, the film dosimetry system (film scanning system) included as an accessory to the device described in paragraph (a) of this section, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Substantial Equivalence Determination

A summary of the information contained in this premarket notification that addresses safety and effectiveness follows.

Safety Summary

RSA XPlan-1 system testing verifies that the beam shaping function generated the correct aperture and that the dose displays in the Geometry Viewer and Dose Summary are correct. Further, it verifies that the PTV generation, Block and MLC generation, DRR display and other new features are accurate.

General Safety and Effectiveness

The device labeling contains instructions for use. It includes indications for use, cautions, warnings and user quality assurance procedures. The training and installation sessions provide assurance that the user understands all aspects of the XPlan-1 System; mechanical, computer and software, plus its intended functionality. This information promotes safe and effective use of the device.
