The 5MP Monochrome LCD Monitor HMD5G21S is intended to be used in displaying and viewing medical images for diagnosis by trained medical practitioners or certified personnel. It is intended to be used in digital mammography PACS, digital breast tomosynthesis and modalities including FFDM.

Device Story

LCD monitors (HMD3C21S, HMD5G21S) designed for medical image display; input via DVI-D or DisplayPort; high-luminance LED-backlit IPS panels. HMD3C21S (3MP color) used for general radiology; HMD5G21S (5MP monochrome) used for mammography, tomosynthesis, and FFDM. Devices feature built-in ambient light and front-facing sensors for luminance calibration via integrated quality-control software. Operated by trained medical practitioners in clinical environments. Output provides high-resolution grayscale or color images for diagnostic review; assists clinicians in interpreting radiological data; supports accurate diagnosis through standardized luminance and spatial resolution performance.

Clinical Evidence

Bench testing only. Performance evaluated per FDA guidance 'Display devices for Diagnostic Radiology' and AAPM-TG18 standards. Metrics include spatial resolution (MTF), pixel defects, artifacts (crosstalk/ghost), luminance (max/min/uniformity), grayscale-to-luminance function (DICOM GSDF), temporal response, and chromaticity/color tracking.

Technological Characteristics

High-luminance LED-backlit IPS LCD panels. HMD3C21S: 3MP (1536x2048), color. HMD5G21S: 5MP (2048x2560), monochrome. Connectivity: DVI-D, DisplayPort. Features: built-in ambient light and front-facing calibration sensors. Compliance: IEC 60601-1, IEC 60601-1-2. Calibration via integrated quality-control software.

Indications for Use

Indicated for trained medical practitioners or certified personnel for the review, analysis, and diagnosis of radiological images. HMD3C21S is for general radiological images (excluding mammography). HMD5G21S is for digital mammography PACS, digital breast tomosynthesis, and FFDM.

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).

Predicate Devices

Dear Hanson Chen:

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

{1}------------------------------------------------

statutes and regulations administered by other Federal agencies. You must comply with all the Act's 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 (QS) 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).
