Intended Use

PaX-Flex3D is a computed tomography x-ray system intended to produce panoramic, cephalometric or cross-sectional images of the oral anatomy on a real time basis by computer reconstruction of x-ray image data from the same axial plane taken at different angles. It provides diagnostic details of the anatomic structures by acquiring 360° rotational image sequences of oral and maxillofacial area for a precise treatment planning in adult and pediatric dentistry. The device is operated and used by physicians, dentists, and x-ray technicians.

Device Story

PaX-Flex3D is a dental diagnostic imaging system utilizing a CMOS digital X-ray detector to acquire 360° rotational image sequences. It performs panoramic, cephalometric, and computed tomography (CT) imaging of the oral and maxillofacial area. Operated by physicians, dentists, or technicians in a clinical setting, the device transforms X-ray data into 3D images via computer reconstruction. These images provide diagnostic details of anatomic structures, assisting clinicians in precise treatment planning for oral surgery or other dental procedures. The system supports real-time image acquisition and reconstruction, facilitating efficient clinical decision-making.

Clinical Evidence

Bench testing only. Performance evaluated against IEC 60601-1, IEC 60601-1-3, IEC 60601-2-7, IEC 60601-2-28, IEC 60601-2-32, IEC 60601-2-44, and IEC 60601-1-2 standards. Non-clinical considerations followed FDA guidance for Solid State X-ray Imaging Devices. All results were satisfactory.

Technological Characteristics

System utilizes CMOS digital X-ray detector; 50-90 kV tube voltage; 4-10 mA tube current; 0.5 mm focal spot size; 2.8 mm Al total filtration. Connectivity via DICOM 3.0. Electrical safety per IEC 60601 series. LDCP logic circuit architecture.

Indications for Use

Indicated for adult and pediatric patients requiring panoramic, cephalometric, or cross-sectional imaging of the oral and maxillofacial anatomy for treatment planning.

Regulatory Classification
