Intended Use
PVmed Contouring Software is a software package. It allows the display, annotation, volume operation, volume rendering, and fusion of medical CT images as an aid during use by radiation therapy planning. it is limited to autocontouring of OARs for head and neck, chest and abdomen, abdomen and pelvis.
Device Story
PVmed Contouring Software is a software package for radiation therapy planning; it processes medical CT images to perform auto-contouring of organs at risk (OARs). Input consists of CT images; the software provides tools for display, annotation, volume rendering, and image fusion. It is intended for use by radiation therapy professionals. The software automates the delineation of anatomical boundaries, which are then reviewed by clinicians to assist in treatment planning. By providing automated contouring, the device aims to improve the efficiency and consistency of the radiation therapy planning workflow. It operates on standard computing platforms (Linux, Windows, Mac OS).
Clinical Evidence
No clinical trials were conducted. Non-clinical bench testing evaluated the accuracy of auto-contouring by comparing software-generated contours against manual contours delineated by radiotherapy doctors with >5 years of experience. Data was sourced from CT images of patients across 5 hospitals. The primary endpoint was the Dice similarity coefficient, which demonstrated that the software meets drawing accuracy requirements.
Technological Characteristics
Software-based medical image management and processing system. Supports DICOM CT image import/export. Features include auto-contouring of OARs, manual contouring tools, image fusion, and 3D volume rendering. Operates on Linux, Windows 10+, and Mac OS 10.14. Software is classified as a 'major' level of concern. Connectivity via standard DICOM protocols.
Indications for Use
Indicated for use as an aid in radiation therapy planning for patients requiring auto-contouring of organs at risk (OARs) in the head and neck, chest, abdomen, and pelvis regions using medical CT images.
Regulatory Classification
Identification
A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.
Special Controls
*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

Dear Chuanji Huang:
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 (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 located 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's
{1}------------------------------------------------
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
