Intended Use

RadiForce RX320 is intended to be used in displaying and viewing digital images for diagnosis of X-ray or MRI, etc. by trained medical practitioners. RadiForce RX320 does not support the display of mammography images for diagnosis.

Device Story

RadiForce RX320 is a 21.2-inch color LCD medical display; used by trained medical practitioners for viewing digital diagnostic images (X-ray, MRI). Device receives digital video input via DVI-D interface; transforms input signals into high-definition visual output. Features Digital Uniformity Equalizer (DUE) to compensate for luminance non-uniformity; improved brightness (900 cd/m2) and contrast (1000:1) compared to predicate. Operates in clinical environments; supports optional photo-sensor and calibration software for luminance management. Output allows clinicians to interpret medical images for diagnostic decision-making; provides high-resolution visualization to aid patient diagnosis.

Clinical Evidence

No clinical data. Substantial equivalence is based on bench testing and technical comparison of display performance characteristics (brightness, contrast, response time, uniformity).

Technological Characteristics

54cm (21.2") TFT Color LCD panel; 2048 x 1536 native resolution; 900 cd/m2 brightness; 1000:1 contrast ratio; 20ms response time. Connectivity via DVI-D. Includes Digital Uniformity Equalizer (DUE) for luminance compensation. Optional photo-sensor and calibration software. Complies with EN60601-1, UL60601-1, CSA C22.2 No. 601-1, FCC-B, VCCI-B.

Indications for Use

Indicated for trained medical practitioners to display and view digital images for diagnosis of X-ray or MRI. Contraindicated for the display of mammography images for diagnosis.

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

• RadiForce R31 and R31-C (K052344)

## Dear Mr. Hashimoto:

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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
