C arm, G arm & O arm
C-arm, G-arm, and O-arm are medical X-ray imaging devices shaped like the letters “C”, “G”, and “O”, as shown in the pictures below. They are commonly used in minimally invasive orthopedic surgeries, combining fluoroscopy and imaging capabilities to provide real-time, high-quality images during procedures.

O arm advantages & disadvantages
O arm advantages
O-arm can quickly provide intraoperative 3D images, reducing the risk of spinal surgery and complications while minimizing radiation exposure.
O arm disadvantages
O-arm is generally more expensive than both the G-arm and C-arm, and it requires a higher level of technical expertise to operate.
G arm advantages & disadvantages
G arm advantages
The main advantage of the G-arm is that it combines a pair of X-ray chains, allowing simultaneous observation on two perpendicular planes. This leads to shorter surgery times, higher accuracy, and lower radiation exposure. The G-arm can remain in a fixed position throughout the procedure. Frequent repositioning of imaging equipment during surgery can increase the risk of infection, but the fixed G-arm minimizes this risk.
G arm disadvantages
G-arms are significantly more expensive but larger and less portable than C-arms.
C arm advantages & disadvantages
C arm advantages
- C arm is less expensive than G arm and O arm both in initial cost and maintenance.
- C-arm can quickly generate cross-sectional, sagittal, coronal, and rotatable 3D images during surgery, providing a 360° viewing angle. This helps doctors accurately assess bone structures and implants from all angles, significantly increasing the success rate of the surgery and reducing the likelihood of complications.
- C-arms are generally more portable and easier to maneuver within the operating room, making them suitable for a wide range of surgical procedures.
- Due to their widespread use, many medical professionals are familiar with C-arm devices, reducing the learning curve and potential for errors.
C arm disadvantages
During surgery, C-arm often needs to be repositioned multiple times, which can take more time and increase radiation exposure for both the patient and the medical staff. This frequent movement can also potentially raise the risk of infection.
Perlove C arm
The Perlove C-arm features a large 3D imaging field of view (FOV) during surgery, allowing for more comprehensive image data collection. It can capture the entire cervical spine, lumbar spine, seven thoracic vertebrae, bilateral sacroiliac joints, femoral head, and unilateral pelvis in a single shot.
The device offers both high-definition and fast acquisition modes, with the fastest mode completing image collection in as little as 30 seconds. This significantly reduces acquisition time while maintaining image quality.

With an isocentric design, the area exposed to X-rays remains centered throughout the scan, eliminating the need for repositioning during the procedure, thereby reducing radiation dose and motion artifacts, and saving time.
The Perlove C-arm can also be integrated with orthopedic surgical navigation systems to perform complex orthopedic surgeries. The combination of the Perlove C-arm and surgical robotic arms has undergone extensive clinical testing and has been well-received and recognized by numerous hospitals both domestically and internationally.
