Intended Use

The 3MP Color LCD Display UMD3-21B01 (MD3-21B01) is indicated for use in displaying radiological images for review, analysis, and diagnosis by trained medical practitioners. The display is not intended for mammography.

Device Story

The UMD3-21B01 is a 21.3-inch 3MP color LCD display used by radiologists and medical practitioners in clinical settings to view radiological images. It accepts DVI-D and DisplayPort signals from a workstation or PC. The device utilizes IPS technology and an LED backlight to render images. It features internal Look-Up Tables (LUT) that store factory-calibrated display modes, including DICOM GSDF compliance, ensuring consistent image quality regardless of the connected display controller. The device includes integrated sensors (backlight, front, and ambient light) for luminance stabilization and quality control. The 'AcuCal' system, consisting of 'AcuCal-Pro' firmware and 'AcuCal Manage' PC software, performs automated luminance calibration and quality control monitoring. By maintaining DICOM conformance and luminance stability, the display assists clinicians in accurate image interpretation, supporting diagnostic decision-making.

Clinical Evidence

Bench testing only. Performance evaluated per FDA guidance 'Display Devices for Diagnostic Radiology' and AAPM TG18 guidelines. Testing included spatial resolution (MTF), pixel aperture ratio, pixel defect analysis, visual artifact assessment, temporal response, luminance range (max/min), DICOM GSDF conformance, angular dependency of luminance, and chromaticity non-uniformity.

Dear Sheng-Sung Jian:

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. 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.
