Adjust the height of the C-Arm to match the targeted body part, whether it's a joint, spine, or another area of interest.
Rotate the C-Arm to find the best angle for imaging, ensuring that the area of interest is clearly visible.
Be mindful of maintaining a safe distance between the C-Arm and the patient or surgical table to avoid obstruction and to prevent any unintended movement.
As you become more comfortable with basic positioning, you can begin using advanced techniques to access more complex imaging angles. The flexibility of the C-Arm allows for tilting, swiveling, and vertical and horizontal adjustments, which are critical when imaging hard-to-reach anatomical areas such as the spine or joints.
Advanced Techniques:
Tilt the C-Arm head to obtain views from difficult angles, such as the underside of the patient or areas obscured by other body parts.
Use the horizontal travel function to shift the machine side-to-side, which is particularly useful when imaging large areas or adjusting the view.
Adjust the vertical lift to ensure the device is correctly positioned relative to the patient's height and the area being imaged.
It is important to ensure that the C-Arm remains stable during imaging to prevent any movement that could result in blurred or inaccurate images. Engaging the brakes and locks on the machine will secure the C-Arm in place, ensuring that it stays in the desired position throughout the imaging process.
Stability Steps:
Double-check that the brakes are fully engaged to prevent any unintended movement during the procedure.
Confirm the machine’s position and stability before starting the imaging process, as even slight shifts can affect image quality.
Utilize the locking mechanisms on the C-Arm to ensure it remains securely positioned during the entire procedure.
Fluoroscopy is an advanced X-ray imaging technique that allows healthcare professionals to observe real-time images of a patient’s internal structures. Unlike traditional X-rays, which capture static images, fluoroscopy provides a continuous series of live images, making it an invaluable tool for guiding surgeries and other medical procedures.
