Mobile C-arm X-ray machine is commonly known as “C-arm fluoroscopy machine”, a key indicator of this type of equipment is the size of the opening, which refers to the C-arm image receiver shell lower edge to the X-ray generator (bulb) shell the distance between the upper edge.
The size of the opening of the C-arm affects the use of the equipment in a number of ways, mainly in the following areas:
I. Ease of access and flexibility of the equipment
Access of the device to and from the operating bed: the size of the opening determines whether the device can be easily accessed or withdrawn from one side of the operating bed. A moderate opening ensures that the equipment can be moved quickly and safely during the procedure, providing the surgeon with enough room to maneuver.
Surgical Preparation and Positioning: A larger opening allows the device to be more flexible during clinical positioning, allowing it to easily snap into place between the operating bed and the patient, reducing the time it takes to repeatedly adjust the position of the C-arm and improving surgical efficiency.

II. Patient safety
Avoiding collision and infection: An opening that is too small may cause the device to come into contact with the patient or monitoring instruments when pushed into the operating bed, increasing the risk of collision or infection. An appropriately sized opening ensures that the device is moved at a safe distance from its surroundings.
iii. Device design and weight
Device size and weight: too large an opening may result in an increase in the size and weight of the entire device, which not only increases the difficulty of transporting and installing the device, but may also affect the stability and mobility of the device during surgery.
IV. Image field of view and imaging quality
The relationship between SID (source image distance) and field of view: SID (i.e., the distance from the X-ray source to the image receiver) is inversely proportional to the image field of view. Although opening size does not directly determine SID, equipment design often requires a balance between opening size, SID, and image field of view.
C-Arm Fluoroscopes with Adjustable Opening Size
For example, the PLX C7600 series C-arm fluoroscopes come with an adjustable SID feature that allows you to freely control the rise and fall of the flat detector to adjust the size of the C-arm opening. When the flat detector rises, it can increase the distance of the C-arm opening, expanding the surgical space and making it easier for the doctor to carry out the positioning. When the detector is lowered, it can be closer to the patient, which not only enlarges the imaging field of view, but also facilitates surgical positioning.
V. Diversity of clinical applications
Adapt to different surgical needs: Different surgeries have different requirements for the opening size of the C-arm. For example, orthopedic surgery may require a larger opening space for osteosynthesis, repositioning and other operations; while neurosurgical angiography and other interventional procedures are more concerned about the imaging quality and stability of the device.
