Intended Use
ART-Plan is a software intended to be used by trained clinicians who are familiar with radiation therapy, such as medical physicists, medical dosimetrists and radiation oncologists. The software consists of different applications, each used for specific purposes at a different phase of radiation treatment planning. ART-Plan offers the following tools to aid in the workflow of radiotherapy treatment: - Multi-modal visualization and rigid- and deformable registration of anatomical and . functional images such as CT, MR, PET-CT, 4D-CT, CBCT and synthetic-CT generated from CBCT - Display of fused and non-fused images to facilitate the comparison and delineation of image data by the user - Manual generation, modification and semi-automatic generation of contours for the ● regions of interest - Automatic generation of contours for organs at risk and healthy lymph nodes, based ● on medical practices, on medical images such as CT and MR images - Generation of synthetic-CT from MR images for supported anatomies - Generation of synthetic-CT from CBCT images for supported anatomies ● - Dose computation on CT and/or synthetic-CT images for external beam irradiation ● with photon beams - Assisted CBCT-based off-line adaptation decision-making for supported anatomies The device is intended to be used in a radiation therapy clinical setting, by trained professionals only.
Device Story
ART-Plan is a standalone software application for radiotherapy treatment planning. It ingests multi-modal medical images (CT, MR, PET-CT, 4D-CT, CBCT) via DICOM. The device uses deep-learning algorithms to perform automatic segmentation of organs at risk and lymph nodes, rigid/deformable image registration, and generation of synthetic-CT images from MR or CBCT inputs. It also provides a dose computation engine for photon beam external beam irradiation and assists in off-line adaptive radiotherapy decision-making. Used in clinical settings by radiation oncologists, physicists, and dosimetrists, the software displays fused/non-fused images and contours to facilitate treatment planning. The output supports clinical decision-making regarding treatment adaptation and plan validation. Benefits include standardized workflows, reduced manual contouring time, and improved accuracy in dose calculation for adaptive radiotherapy.
Clinical Evidence
No clinical studies were conducted. Evidence consists of bench testing, including qualitative and quantitative validation of auto-segmentation, image registration, synthetic-CT generation, and dose computation modules. Performance metrics included Dice Similarity Coefficient (DSC) (mean ≥ 0.8 for segmentation; ≥ 0.81 for registration), Target Registration Error (TRE < 2mm), and gamma passing rates (≥ 95% for 2%/2mm). Qualitative evaluations by experts used a 3-point scale (A/B/C), with acceptance criteria requiring ≥ 85% A+B scores. Testing used retrospective clinical data cohorts (e.g., 315,373 samples for auto-segmentation) to demonstrate generalization and non-inferiority to predicate devices.
Technological Characteristics
Standalone software application; accessed via web browser (Chrome, Firefox, Edge) on PC/tablet/phone. Uses deep learning algorithms for auto-segmentation, image registration, and synthetic-CT generation. Supports DICOM 3.0 interoperability. Dose engine performs photon beam calculations. Software is classified as 'major' level of concern. No hardware components; sterilization not applicable.
Indications for Use
Indicated for cancer patients prescribed radiotherapy treatment for whom relevant modality imaging data is available. Not intended for patients < 18 years. Users: trained medical professionals (radiotherapists, radiation oncologists, medical physicists, dosimetrists). Environments: hospitals, clinics, and radiation therapy facilities.

Dear Bhairavi Ajachandra:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
