• Applicant: Direct Digital Imaging Technology (Beijing), Inc.
• Product Code: MQB · Radiology
• Decision Date: May 18, 2009
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 892.1680
• Device Class: Class 2

Intended Use

The WV1417A Digital X-ray Direct Imaging Flat Panel Detector System provides a digital image capture capability for conventional radiographic examinations (excluding fluoroscopic, angiographic, and mammographic applications). The device has application wherever conventional screen-film systems are currently used.

Device Story

The WV1417A is a digital X-ray flat panel detector system replacing traditional film-based radiography. It captures X-ray signals via a detector array, which are then processed by an array controller and system controller. The system controller, installed on customer-provided PC hardware, manages exposure synchronization, image acquisition, and basic image processing (gain, offset, and defective pixel correction). Operators use the system to preview, store, and transmit digital images via LAN to workstations, printers, or archives. The device is used in clinical settings for conventional radiographic exams, allowing immediate image quality verification without chemical film development. This improves workflow efficiency and provides digital diagnostic images for healthcare providers.

Clinical Evidence

The submission states that a clinical test report was provided, but does not detail specific study results, sample sizes, or performance metrics. Electrical safety and electromagnetic compatibility testing were conducted per IEC 60601-1 and IEC 60601-1-2.

Technological Characteristics

Digital X-ray flat panel detector system. Components include a detector array, array controller, and system controller (software). Connectivity via LAN. Complies with IEC 60601-1 (electrical safety) and IEC 60601-1-2 (EMC). Software performs gain, offset, and defective pixel correction.

Indications for Use

Indicated for digital image capture in conventional radiographic examinations, excluding fluoroscopic, angiographic, and mammographic applications. Intended for use wherever conventional screen-film systems are currently used.

Regulatory Classification

Identification

A stationary x-ray system is a permanently installed diagnostic system intended to generate and control x-rays for examination of various anatomical regions. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

Special Controls

*Classification.* Class II (special controls). A radiographic contrast tray or radiology diagnostic kit intended for use with a stationary x-ray system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

#### 3. Device Description

1

The WV1417A Digital X-ray Direct Imaging Flat Panel Detector System is used to directly capture and convert conventional projection X-ray images to digital images. A image preview function can be displayed on a review monitor for viewing. The diagnostic image can be transmitted through LAN for diagnostic viewing and printing. The device provides digital image capture for conventional radiographic examinations, excluding fluoroscopic, angiographic and mammographic applications. The system differs from traditional X-ray systems in that instead of exposing a film for subsequent wet chemical processing to create a hardcopy image, a device called a detector array is used to capture the image in electronic form. The digital data are then used to produce hardcopy and softcopy images.

The WV1417A Digital X-ray Direct Imaging Flat Panel Detector System (Fig.VI-1) is composed of the following:

A detector array is used to capture the diagnostic image.

An array controller is used to control detector array, harmonize the working between the array controller and high-voltage generator for exposal synchronization and image transmission.

A system controller is used to enter patient demographic information, initiate the exposure process, review captured images, and accept or reject captured images. The system controller is also used to send images to a hardcopy printer, workstation, or archive, and manage images temporarily stored in its database. Here, the system controller is the software device and which should install in the PC hardware system purchased by themselves of customer.

The system controller also can make some disposal for the original image, such as gain, offset and defective pixel correction.

By capturing, previewing, and storing and image, the system enables an operator to check the quality of an image at the time of exposure without having to develop a film.

Dear Ms. Hong:

This letter corrects our substantially equivalent letter of May 18, 2009.

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 class II (Special Controls), it may be subject to such additional controls.
