Intended Use
CBCT, panoramic x-ray imaging system with cephalostat, is an extra oral 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 dental maxillofacial 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.
Device Story
RCT700 is a dental CBCT, panoramic, and cephalometric X-ray system. It uses a rotating C-arm with an X-ray generator and flat panel detector to capture 2D and 3D maxillofacial images. The device is operated by dentists or qualified healthcare professionals in clinical settings. It transforms X-ray signals into digital images via direct or indirect detection methods. The system includes a PC for image reconstruction and viewing. Output images are used by clinicians for diagnosis and treatment planning, such as implantology and orthodontics. Benefits include improved visualization of dental and maxillofacial structures for accurate clinical decision-making.
Clinical Evidence
Clinical evaluation involved two licensed practitioners observing and verifying system performance. Clinical images were collected from the new detectors (FXDD-0606CA, 1717SCC) at two clinical sites across various patient demographics. Practitioners confirmed that clinical diagnosis and visualization of structures were acceptable in the regions of interest. This data supplemented extensive non-clinical bench testing.
Technological Characteristics
Extra-oral X-ray system; C-arm geometry; high-frequency generator; flat panel detectors (FXDD-0606CA, 1717SCC); 60-90kVp; 4-17mA; 0.5mm focal spot; DICOM 3.0 compatible; Giga-Ethernet connectivity; wall/floor mount; Class I with Type B applied parts; IEC 60601-1, 60601-1-3, 60601-2-63, 60601-1-2 compliance.
Indications for Use
Indicated for dental radiographic examination of teeth, jaw, and oral structures (panoramic, implantology, TMJ, cephalometry, maxillofacial 3D imaging) in patients over 5 years old. No restrictions on gender, weight, or health condition.

#### 6. Device Description
System purpose RCT700 is 3D computed tomography for scanning hard tissues like bone and teeth. By rotating the c-arm which is embedded with high voltage generator all-in-one x-ray tube and a detector on each end, CBCT images of dental maxillofacial is attained by recombining data from the same level that are scanned from different angle.
Panoramic image scanning function for attaining image of whole teeth, cephalometric scanning option for attaining cephalic image, and Model Scan option for attaining dental model CBCT image are included.
#### 7. Indication for use
CBCT, panoramic x-ray imaging system with cephalostat, is an extra oral 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 dental maxillofacial 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."
#### 8. 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.
#### 9. Operating principle
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 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 Xray generator to get the image of interests. The purpose of this mechanism is to provide the images in Ray Co.,Ltd Page 5-3
{7}------------------------------------------------
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 method depending on the interior structure materials.

## 10. Comparison with predicate device
The product is principally just the same as in the previous 510(k) #K160525.
We changed a some scan protocol from the Predicate Device(K160525). And added a CT/Pano and ceph detector to the predicate Device #K160525. But, these detectors is used predicate Device #K181452.
The compared technical features for imaging parameters, resolution, and other basic characteristics are matching very closely, and the differences are so small that they do not have any effect on performance in practice. Both devices conformance standards.
