The Detector model mounted in our Dental X-ray system RAYSCAN α-M3DL [One shot Ceph] is the PaxSca 4336X model. The Non-clinical report provided by Varian, manufacturer of the Detector, was submitted in place of the Non-clinical report regarding the Solid state Detectors required by FDA. The Non-clinical report provided by the manufacturer Varian includes and describes the Non-Clinical Data for both models PaxScan 4336W and PaxScan 4336WX. In particular the PaxScan 4336W model includes a wireless detector function however PaxScan 4336X, the detector mounted in our RAYSCAN α-M3DL [One shot Ceph] system is a detector without the wireless function, therefore the data for wireless function is not attached. SMARTDent software for processing and archiving is optional. ### Indication for use RAYSCAN α-Expert 3D, panoramic x-ray imaging system with cephalostat, is an extraoral source x-ray system, which is intended for dental radiographic examination of the teeth, jaw, and oral structures, specifically for panoramic examinations and implantology and for TMJ studies and cephalometry, and it has the capability, using the CBVT technique, to generate dento-maxillo-facial 3D images. The device uses cone shaped x-ray beam projected on to a flat panel detector, and the examined volume image is reconstructed to be viewed in 3D viewing stations. 2D Image is obtained using the standard narrow beam technique. "CAUTION: Federal law restricts this device to sale by or on the order of a dentist. ### Patient population The patient population can be the possible person who can be taken X-ray diagnostic radiation exposure. There is no restriction for ethnic group, Gender, weight, health, or condition. We recommend patients for x-ray diagnostic radiation exposure to be over 5 years old. {7}------------------------------------------------ #### Device functions The purpose of this unit is diagnose clinical structures of a tooth and head areas mainly by using the characteristics of permeability from X-ray. The principle of functioning and formations are as following. The machine is made of X-ray generator and arms in which transfers X-ray signals to a sensor in 2D. Also, an object that has a magnification is required in a distance. Moreover, the unit has to be adjustable depending on height of a patient and PC system to reconstruct an image. The arm parts are controlled for rotating and linear moving to synchronize between the sensor and X-ray generator to get the image of interests. The purpose of this mechanism is to provide the images in 2D or/and 3D as preferred to diagnose in a monitor. CBCT provides in 3D images as reconstructed and Panorama is to diagnose the structures in a panoramic view. Cephalometric allows for orthodontic treatment. These 3 functions could be in 1 system, Panorama with Cephalometric, or Panorama only system depending on the needs. To provide the features as mentioned above, digital transferring from permeated X-ray to absorbing to the sensor is essential and all the process are proceed in Detector. Detector transfers X-ray to light depending on the structure materials. Detector is separated into indirect method that the light is changed to digital signals on photodiode and direct method in which the light is directly transferred to digital signal. This unit is using both direct and indirect method depending on the interior structure materials. #### Operating principle of the detector X-ray data entered into the detector from an outside source is converted to visible ray by detector's Scintillator and The visible ray is transferred to CMOS ASIC and converted to an Electric signal to form an image signal. Then the signal is changed to a Digital form and through the high speed LAN cable, the acquired image data is transmitted to the PC. Acquired resulting image is displayed on the monitor by the PC Software. #### Comparison of the detector One shot ceph detector installed on the One shot ceph option RAYSCAN α-Multi3D in Predicate devices RAYSCAN α-Expert 3D[K122981, Traditional] and RAYSCAN α {8}------------------------------------------------ Expert3D[K131695, special] is SDX-4336CP (model name).

Performance (Imaging performance) testing was conducted according to standard of IEC 61223-3-4 and IEC 61223-3-5. All test results were satisfactory. Non-clinical and test was conducted for imaging performance of the proposed detector in accordance with FDA Guidance "Guidance for the submissions of 510(k)'s for Solid State Xray Imaging Devices". All test results were satisfactory. Both of the predicate device and proposed device are based on Csi scintillator designed for general radiography. MTF (Modulation Transfer Function) and DOE (Detective Quantum Efficiency) were test and measured by IEC 62220-1. RAYSCAN α-M3DL and RAYSCAN α-M3DS system's new sensor and compared with the predicate device with regard to Modulation Transfer Function (MTF) and Device Quantum Efficiency (DQE). Base on the Non-clinical test result, even though the new Csi detector differs in term of the pixel size and active area, the diagnostic image quality of the new detector is equal or better than those of the predicate device and there is no significant difference in efficiency and safety. Clinical considerations were conducted according to FDA Guidance "Format for Traditional and Abbreviated 510(k)s, section 20". Clinical images were provided these images were not necessary to establish substantial equivalence based on the modifications to the device but they provide further evidence in Ray Co.,Ltd {21}------------------------------------------------ addition to the laboratory performance data to show that the complete system works as intended. For clinical testing, two licensed practitioners/clinicians observed and verified that dental X ray system from RAYSCAN α. The clinical imaging samples are collected from the new 2 one shot detector on propose device at the 2 offices where the predicate device is installed on clinical consideration report for the clinical test images were gathered from the new 2 one shot ceph detector installed with RAYSCAN α-M3DL and M3DS on any protocols with random patient age, gender, and size. As licensed practitioners or clinician diagnoses of the images, it might be proved that the clinical diagnosis and structures are acceptable in the region of interests. The manufacturing facility is in conformance with the relevant EPRC standards as specified in 21 CFR 1020.30, 31, and 33 and the records are available for review. ### Conclusions Based on a comparison of intended use, indications, constructions, construction materials, principal of Operation, features and technical data, the RAYSCAN α-Expert 3D system are safe and effective to perform its intended use as well as substantially equivalent to the predicate device.
