Intended Use

Intended for digital image capture use in general radiographic examinations, wherever conventional screen-film systems may be used, excluding fluoroscopy, angiography and mammography. ViZion DR + Wireless allows imaging of the skull, chest, shoulders, spine, abdomen, pelvis, and extremities.

Device Story

ViZion DR + Wireless is a digital radiography system consisting of a flat panel detector (FPD) and software. It replaces conventional film-screen systems for general radiographic examinations. The device captures X-ray signals using a Cesium Iodide (CSI) or Gadolinium Oxysulfide (GOS) scintillator, converting them into digital images. It features Automatic Exposure Detection (AED), eliminating the need for direct generator synchronization, though wired synchronization is supported for specific generators. The system transmits images via Gigabit Ethernet or IEEE 802.11 a/b/g/n wireless protocols to a PACS environment. Operated by clinicians in a filmless environment, the system provides digital images for diagnostic review. The primary benefit is improved cost-effectiveness and workflow efficiency compared to traditional film-based radiography.

Clinical Evidence

Clinical image evaluation performed by a board-certified radiologist. Images acquired with the modified CSI scintillator panel were compared to the predicate GOS panel. The radiologist concluded that the image quality of the modified device is as good as or better than the predicate device.

Technological Characteristics

Digital X-ray receptor panel (14" x 17"). Scintillator: Cesium Iodide (CSI) or Gadolinium Oxysulfide (GOS). Pixel size: 150 µm. A/D conversion: 14-bit. Connectivity: Gigabit Ethernet (1000BASE-T) and IEEE 802.11 a/b/g/n. Power: AC line or rechargeable Lithium battery. Electrical safety: IEC 60601-1. EMC: IEC 60601-1-2. Compliance: FCC Part 15. DICOM 3.0 compatible.

Indications for Use

Indicated for digital image capture in general radiographic examinations (skull, chest, shoulders, spine, abdomen, pelvis, extremities) in patients requiring X-ray imaging. Contraindicated for fluoroscopy, angiography, and mammography.

- 1. Identification of the Device: Proprietary-Trade Name: ViZion DR + Wireless Classification Name: Stationary x-ray system. Product Code MOB Common/Usual Name: Digital X-Ray Receptor Panel Device Class/Regulation Number: Class II per regulation 892.1680
- 2. Equivalent legally marketed device: ViZion DR + Wireless, K152279, Viztek. Classification Name: Stationary x-ray system, Product Code MQB Common/Usual Name: Digital X-Ray Receptor Panel Device Class/Regulation Number: Class II per regulation 892.1680
- 3. Indications for Use (intended use) ViZion DR + Wireless is intended for digital image capture use in general radiographic examinations, wherever conventional screen-film systems may be used, excluding fluoroscopy, angiography and mammography. ViZion + Wireless allows imaging of the skull, chest, shoulders, spine, abdomen, pelvis, and extremities.
- 4. Description of the Device: The ViZion DR + Wireless system represents the straightforward integration of a modified digital x-ray receptor panel and our previously cleared software. This is a MODIFICATION of our clearance K152279 wherein we have changed the panel scintillator to Cesium Iodide in addition to having the GOS scintillator available. Changing the scintillator is the only modification.

ViZion DR + Wireless is a Digital Radiography system, featuring an integrated flat panel digital detector (FPD). ViZion DR + Wireless is designed to perform digital radiographic examinations as a replacement for conventional film. This integrated platform provides the benefits of PACS with the advantages of digital radiography for a filmless environment and improves cost effectiveness. The major functions and principle of operation of the Viztek PACS and the new receptor panel were not changed. Our predicate is ViZion DR + Wireless, K152279. We do not supply the router, but any router meeting the IEEE 802.11 a/b/g/n specifications will work. With the advent of AED (automatic exposure detection) by the panel, integration with or connection to specific generators is no longer required. If the user decides NOT to use AED, wired synchronization with Sedecal Series SHF generators is known to work.

- 5. Safety and Effectiveness, comparison to predicate device. The results of clinical image inspection, bench, and test laboratory results indicates that the new device is as safe and effective as the predicate device. Clinical images collected demonstrate equal or better image quality as compared to our predicate.

- 7. Summary of Bench Testing Conducted: IEC Standards were employed for: Electrical Safety and Electromagnetic Compatibility. We compared MTF and DQE measurements for the original and wireless versions of the panel and found them to be similar enough not to make a notable difference in acquired images. Risk Analysis and System operation verification tests were conducted in accordance with FDA guidance documents. Since no software modifications were required, confirmation testing was performed. Wireless communication testing was performed to verify wireless connectivity. We used a Cisco Linksys EA2700. The device was also found to comply with FCC requirements for wireless operation.
- Summary of Clinical Testing: Clinical images were acquired and evaluated by a board certified 8. radiologist who concluded the images from the modified panel are as good as or better than the images acquired with the predicate panel.
- 9. Conclusion: After analyzing bench, clinical image, and external laboratory testing to applicable standards, it is the conclusion of Viztek Inc that the ViZion DR + Wireless is as safe and effective as the predicate device, has few technological differences, and has no new indications for use, thus rendering it substantially equivalent to the predicate device.
