Intended Use
CadPlan is used to plan radiation therapy treatments employing linear accelerators and other similar teletherapy devices and x-ray energies from 4 to 50 MV, as well as Cobalt-60, and electron energies from 4 to 50 MeV, and to plan brachytherapy treatments.
Device Description
CadPlan Helios is an inverse planning tool for creating highly conformal plan using intensitymodulated fields. Inverse planning refers to the process of computing the optimum field intensities for the required numbers of beams to achieve the desired dose of distribution with specified complaints. It allows for creation of in-field intensity profiles that produce the desired dose distribution as precisely as possible. Helios computes the in-field intensities on the basis of specified clinical constraints for the desired dose distribution inside target volumes and critical organs. The calculated intensity profiles are then converted to a pattern of dynamic Multi-Leaf Collimator (MLC) motions. The combination of modulated dose delivery and dynamic MLC motion allows dose to be conformed precisely to anatomical structures. Helios implements the inverse planning algorithm and support of dynamic MLC for Intensity Modulated Radiation Therapy.
More Information

None

No
The description focuses on "inverse planning" and "algorithms" for calculating optimal field intensities based on specified constraints, which are standard computational techniques in radiation therapy planning and do not inherently indicate the use of AI or ML. There are no mentions of AI, ML, or related concepts like training/test sets.

No.
The device is a treatment planning system used to compute optimal field intensities and create treatment plans for radiation therapy, not a device that directly administers therapy.

No

Explanation: The device is described as a planning tool for radiation therapy treatments, and not for diagnosing medical conditions. It computes dose distributions and intensity profiles, which are part of treatment planning, not diagnosis.

Yes

The device description focuses entirely on the software's functionality for inverse planning in radiation therapy. There is no mention of any accompanying hardware components that are part of the device itself. While it interacts with linear accelerators and MLCs, these are external devices used in the treatment delivery, not components of the CadPlan Helios device as described.

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

Here's why:

  • Intended Use: The intended use clearly states that CadPlan is used for planning radiation therapy treatments. This is a therapeutic application, not a diagnostic one.
  • Device Description: The description details how the software helps in computing and delivering radiation doses to achieve a desired dose distribution within the patient's body. This is directly related to treatment, not diagnosis.
  • Lack of Diagnostic Elements: There is no mention of the device being used to analyze biological samples (blood, tissue, etc.), detect diseases, or provide diagnostic information about a patient's condition.

IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. CadPlan's function falls squarely within the realm of treatment planning and delivery, which is distinct from in vitro diagnostics.

Intended Use / Indications for Use

To automatically design the beam profiles that most closely generate the desired dose distribution.
CadPlan is used to plan radiation therapy treatments employing linear accelerators and other similar teletherapy devices and x-ray energies from 4 to 50 MV, as well as Cobalt-60, and electron energies from 4 to 50 MeV, and to plan brachytherapy treatments.

§ 892.5050 Medical charged-particle radiation therapy system.

(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.

Product Description:

CadPlan Helios is an inverse planning tool for creating highly conformal plan using intensitymodulated fields. Inverse planning refers to the process of computing the optimum field intensities for the required numbers of beams to achieve the desired dose of distribution with specified complaints. It allows for creation of in-field intensity profiles that produce the desired dose distribution as precisely as possible.
