Intended Use
Mobius3D software is used for quality assurance, treatment plan verification, and patient alignment and anatomy analysis in radiation therapy. It calculates radiation dose three-dimensionally in a representation of a patient or a phantom. The calculation is based on read-in treatment plans that are initially calculated by a treatment planning system, and may additionally be based on external measurements of radiation fields from other sources such as linac delivery log data. Patient alignment and anatomy analysis is based on read-in treatment planning images (such as computed tomography) and read-in daily treatment images (such as registered cone beam computed tomography). Mobius3D is not a treatment planning system. It is only to be used by trained radiation oncology personnel as a quality assurance tool.
Device Description
Mobius3D is a software product used within a radiation therapy clinic for quality assurance and treatment plan verification. It is important to note that while Mobius3D operates in the field of radiation therapy, it is neither a radiation delivery device (e.g. a linear accelerator), nor is it a treatment planning system (TPS). Mobius3D cannot design or transmit instructions to a delivery device, nor does it control any other medical device. Mobius3D is an analysis tool meant solely for quality assurance (QA) purposes when used by trained medical professionals. Being a software-only QA tool, Mobius3D never comes into contact with patients. Mobius3D performs dose calculation verifications for radiation treatment plans by doing an independent calculation of radiation dose. Radiation dose is initially calculated by a treatment planning system (TPS), which is a software tool that develops a detailed set of instructions (i.e. a plan) for another system (e.g. a linear accelerator) to deliver radiation to a patient. The dose calculation performed by Mobius3D uses a proprietary collapsed cone convolution superposition (CCCS) algorithm. Mobius3D also performs dose delivery quality assurance for radiation treatment plans by using the measured data recorded in a linear accelerator's delivery log files to calculate a delivered dose. This is presented to the end user in a software component of Mobius3D called MobiusFX. The MobiusFX component is available to users through licensing as an add-on to the core Mobius3D software features. Compared to the previously cleared Mobius3D v 1.3.2 (K140660), Mobius3D v 2.0.0 contains the additional intended use of performing quality assurance of a patient's alignment and anatomy analysis. This analysis is based on comparison of Cone Beam Computed Tomography (CBCT) images taken immediately before treatment to the images used for treatment planning, which are typically acquired using standard Computed Tomography (CT). This analysis is presented to the end user in an add-on software module within Mobius3D called CBCT Checks.
More Information

There are no Reference Device(s) K/DEN numbers listed in the text. The "Reference Device(s)" section explicitly states "Not Found".

No
The document describes the use of a proprietary collapsed cone convolution superposition (CCCS) algorithm for dose calculation and image comparison for patient alignment, but does not mention AI or ML.

No
This device is described as a "quality assurance tool" and "analysis tool meant solely for quality assurance (QA) purposes" in radiation therapy. It does not directly treat or diagnose patients.

No

The intrinsic function of a diagnostic device is to diagnose a disease or condition, which is not what this device does. This device is a quality assurance tool for radiation therapy, verifying treatment plans and patient alignment, and analyzing anatomy. It does not identify or characterize diseases.

Yes

The device description explicitly states "Being a software-only QA tool, Mobius3D never comes into contact with patients." and describes its function as an analysis tool that operates on data from other systems. It does not mention any associated hardware components that are part of the device itself.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, to provide information for diagnostic, monitoring, or compatibility purposes.
  • Mobius3D's Function: Mobius3D is a software tool used for quality assurance and treatment plan verification in radiation therapy. It analyzes radiation dose calculations and patient alignment based on medical images (CT and CBCT) and treatment plan data.
  • Lack of Specimen Analysis: Mobius3D does not examine any biological specimens from the human body. Its analysis is based on digital data derived from imaging and treatment planning systems.
  • Purpose: Its purpose is to verify the accuracy of radiation treatment plans and patient positioning, not to diagnose a disease or monitor a patient's biological state through specimen analysis.

Therefore, Mobius3D falls under the category of a medical device used in the context of radiation therapy treatment planning and quality assurance, but it does not meet the definition of an In Vitro Diagnostic.

when used by trained medical professionals. Being a software-only QA tool, Mobius3D never comes into contact with patients.

Mobius3D performs dose calculation verifications for radiation treatment plans by doing an independent calculation of radiation dose. Radiation dose is initially calculated by a treatment planning system (TPS), which is a software tool that develops a detailed set of instructions (i.e. a plan) for another system (e.g. a linear accelerator) to deliver radiation to a patient. The dose calculation performed by Mobius3D uses a proprietary collapsed cone convolution superposition (CCCS) algorithm.

Mobius3D also performs dose delivery quality assurance for radiation treatment plans by using the measured data recorded in a linear accelerator's delivery log files to calculate a delivered dose. This is presented to the end user in a software component of Mobius3D called MobiusFX. The MobiusFX component is available to users through licensing as an add-on to the core Mobius3D software features.

Compared to the previously cleared Mobius3D v 1.3.2 (K140660), Mobius3D v 2.0.0 contains the additional intended use of performing quality assurance of a patient's alignment and anatomy analysis. This analysis is based on comparison of Cone Beam Computed Tomography (CBCT) images taken immediately before treatment to the images used for treatment planning, which are typically acquired using standard Computed Tomography (CT). This analysis is presented to the end user in an add-on software module within Mobius3D called CBCT Checks.

5.9 Intended Use

Mobius3D software is used for quality assurance, treatment plan verification, and patient alignment and anatomy analysis in radiation therapy. It calculates radiation dose three-dimensionally in a representation of a patient or a phantom. The calculation is based on read-in treatment plans that are initially calculated by a treatment planning system, and may additionally be based on external measurements of radiation fields from other sources such as linac delivery log data. Patient alignment and anatomy analysis is based on read-in treatment planning images (such as computed tomography) and read-in daily treatment images (such as registered cone beam computed tomography).

Mobius3D is not a treatment planning system. It is only to be used by trained radiation oncology personnel as a quality assurance tool.

5.10 TECHNOLOGICAL CHARACTERISTICS SUMMARY

The principle technological characteristic of Mobius3D is to perform quality assurance evaluations on the radiation treatment planning system (TPS) and radiation delivery systems (e.g. linear accelerators). Mobius3D (v 2.0.0) adds the technical characteristic of performing comparative analysis between patient images acquired at different times using different image modalities.
