Intended Use

Lux HD 2530 Detector is indicated for digital imaging solutions designed to provide general radiographic diagnosis for human anatomy including both adult and pediatric patients. It is intended to replace film/screen systems in all general-purpose diagnostic procedures. Lux HD 2530 Detector is not intended for mammography or dental applications.

Device Story

Lux HD 2530 is a digital flat panel detector for general radiography. It uses a CsI scintillator to convert X-rays to visible light, which is then transformed into electronic signals by a TFT/diode capacitor array. The device transmits digital image data to a PC via wired (Gigabit Ethernet) or wireless (IEEE 802.11a/b/g/n/ac) connection. Operated by clinicians in clinical settings, the detector integrates with a DR software platform for image acquisition, enhancement, and viewing. It features Automatic Exposure Detection (AED) to trigger image acquisition upon X-ray detection and Detector Exposure Control (DEC) to signal the high-voltage generator to terminate exposure once a target dose is reached. The output assists physicians in diagnosing disease or injury, potentially reducing patient radiation dose through precise exposure control.

Clinical Evidence

Bench testing only. Performance evaluated via electrical safety, EMC, biological evaluation, wireless coexistence, and cybersecurity testing. No clinical data provided.

Technological Characteristics

Flat panel detector with CsI scintillator, TFT readout, 16-bit ADC. Active area 25cm x 30cm, 100μm pixel size, 5.0 lp/mm spatial resolution. Connectivity: Gigabit Ethernet, IEEE 802.11a/b/g/n/ac. IP67 rating. Carbon fiber construction. Air-cooled. Powered via 10-pin port.

Indications for Use

Dear Junjie Qian:

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.

# 8. Minimum requirement for connection

Lux HD 2530 Detector connected via wireless and wired communication.

Operating System: Windows 11

CPU: Intel Core i3- 8100 3.6GHz 4C 65W

Memory: 16GB (2x8GB) DDR4 2666 DIMM

Hard Disk: 1TB

# 9. X-ray exposure mode

The AED (Automatic Exposure Detection) trigger module is a unit can connect X-ray signal in the Lux HD 2530 Detector. Once there is X-ray generator exposure exist, the AED trigger module will detect the X-ray radiation and output signal to the detector. Until the exposure finished, the detector will receive a signal which represent the end of exposure from the inner trigger module and begin to acquire the image.

The DEC (Detector Exposure Control) trigger module is a unit can cutoff HVG output when patients need specified dose, which avoid extra dose absorbed by patients. Once the dose detected by the detector reaches the target value, the detector will send a cut-off signal to the high-voltage system. This signal indicates that no further exposure from HVG is required.
