Types of C-Arm Machines: Mini, Compact, Full-Size, Vascular, 3D

How C-arms are classified

There is no single official classification, but buyers usually sort mobile C-arms by four features: the receptor (image intensifier or flat panel), the size of the detector, the generator power and the software package. A fifth factor is whether the system has 3D or navigation functions. Combining these gives the practical classes described below.

Before you read on, it helps to be clear on the basics: what is a C-arm machine covers the shared components.

Mini and compact C-arms

Mini C-arms are small, low-power units for the hand, wrist, foot and ankle. They are used in clinics and day-surgery rooms. Compact C-arms are a step up: lighter than a traditional system, but with a flat-panel detector and a surgical generator. The Arcovis DRF-C belongs to this class with its compact and lightweight design, 21 × 21 or 30 × 30 cm detector options and an onboard 27″ monitor.

See mini and full-size C-arms for a more detailed comparison.

Full-size surgical C-arms

Full-size mobile C-arms are the workhorse for trauma, orthopaedics, urology, pain and general surgery. They have a detector in the 9 to 12 inch or 21 to 30 cm range, a generator of several kilowatts and image tools such as stitching and metal artefact suppression. The PLX C22 is a full-size flat-panel model, and the PLX C7100 is a flat-panel model for use across several departments with a generator up to 25 kW.

Choose a flat panel when image detail, metal visibility and software tools matter, and an image intensifier for simpler needs and tighter budgets. Read image intensifier vs flat panel to compare.

Vascular and interventional C-arms

Vascular C-arms add digital subtraction angiography, road mapping, an injector interface and a generator and tube with the heat capacity for long runs. They are used in vascular surgery, interventional oncology and hybrid operating rooms. The PLX C9100 offers DSA, roadmap, a high-pressure injector interface, a tableside controller and circulating cooling for extended high-frame-rate fluoroscopy.

Because a vascular C-arm is more demanding, plan the room, the table and the protective equipment together with the unit. Our article on vascular C-arms lists the specification points.

3D and navigation C-arms

A 3D C-arm rotates around the patient to reconstruct slices, which is useful in spine and complex trauma. The PLX C7600 gives transverse, sagittal and coronal images and 3D views, with a 30-second 3D acquisition and 8-second reconstruction, a 94 cm free space and position memory with three-way lasers. Such systems let surgeons check implant position before leaving the OR.

3D is an investment in workflow as well as hardware: the team needs training and a defined protocol. For comparison with other intraoperative systems, see C-arm vs O-arm.

• Mini: extremities, clinics
• Compact flat panel: small theatres
• Full-size: trauma, orthopaedics, urology, pain
• Vascular: DSA, roadmap, injector interface
• 3D: spine and complex trauma

Common mistakes when choosing a type

Three mistakes recur. The first is buying on detector size alone: a large panel on an underpowered generator still struggles with thick anatomy, so check kilowatts and heat capacity as well. The second is ignoring the room, because a vascular or 3D unit needs more floor space, power and shielding than a compact system. The third is leaving out software: stitching, DSA, metal artefact tools and 3D are usually licensed separately.

Ask suppliers to quote the same class of machine with a written list of included and optional software, and compare total scope, not the headline model name. Also ask how the unit can be upgraded, since some options can be added later and others cannot.

Matching type to department

Start from the most demanding procedure on your list. A hand-surgery clinic can buy a mini unit; a district hospital with trauma, orthopaedics and urology should consider a full-size flat-panel C-arm; a vascular or hybrid programme needs a vascular package; a spine centre may justify 3D. Buying a larger class than needed is a common source of overspending.
