● Control box (optional)
Key features and benefits
Precise positioning: the cornerstone of diagnostic imaging
The scanning accuracy of a dental CBCT scanner depends directly on the precision of patient positioning. Our lifting column and linear actuator system offers extremely high repeatability and stepless adjustment capability—the scan table can be precisely raised or lowered to align with the scan's epicenter, while the headrest can be fine-tuned to millimeter precision. Positioning conditions remain identical for every scan, fundamentally ensuring the accuracy and reproducibility of three-dimensional reconstructed images.
Smooth operation, eliminating image artifacts
Any movement during the scanning process may result in motion artifacts in the reconstructed images, compromising diagnostic accuracy. Our lifting column utilizes a high-precision transmission mechanism and zero-backlash design, ensuring the lifting process is constant, smooth, and free from jolts or wobbles throughout. The transition from a seated to a supine position, and the rise of the scan table from the low position to the scanning position, is smooth and seamless throughout. This prevents the patient from feeling anxious or uncomfortable, and ensures that image acquisition is not compromised by mechanical vibrations.
Lifting columns – confidently withstanding high eccentric loads
The scan table of a dental CBCT scanner must support the weight of the patient's upper body, and the point of force application is often offset from the central axis of the column, resulting in significant eccentric loads and bending moments. Our lifting columns possess strong resistance to lateral torque; they maintain structural stability and smooth lifting motion even when bearing eccentric loads, thereby eliminating, from a mechanical perspective, table wobbling and positioning deviations caused by uneven loading.
High protection rating, suitable for medical disinfection environments
Dental CBCT equipment operates in a medical environment subject to frequent cleaning and disinfection. Our lifting columns and actuators feature a high protection rating, providing full resistance to corrosion from cleaning agents and disinfectants. The use of corrosion-resistant materials and a sealed structural design ensures the equipment operates stably over the long term, even under the stringent disinfection requirements of a medical setting.
Quiet operation, creating a pleasant clinical atmosphere
The dental CBCT scanning process itself requires patients to remain relaxed and cooperative; any additional noise may increase patient anxiety. Our lifting columns and actuators maintain low noise levels during operation, with the scan table's elevation and headrest fine-tuning occurring silently, creating a quiet and relaxing examination environment for patients.
Built-in Hall sensors, enabling precise control for customers
Our actuators and columns are equipped with built-in Hall sensors, which provide real-time feedback on travel position and operational status via pulse signals. This enables the customer's control system to precisely monitor real-time data on scan table height and headrest position, facilitating intelligent functions such as one-touch reset and position memory. The real-time feedback from the Hall sensors provides a reliable positional reference, ensuring consistent positioning for every scan.
