PMI Foam: Revolutionizing CT Scan Table Tops for Unmatched Image Clarity & Patient Comfort
When it comes to accurate medical diagnostics, every component of a CT scanner matters. The table top, often overlooked, plays a critical role in image quality and patient experience. This is where advanced PMI (Polymethacrylimide) foam is making a significant impact, replacing traditional wood or composite cores to set a new standard in CT imaging technology.

The Critical Challenge: Minimizing Artifacts, Maximizing Clarity
CT imaging relies on precise X-ray measurements. Any material in the scan path that interferes with X-ray transmission can cause imaging artifacts—streaks, shadows, or distortions that obscure critical anatomical details. Traditional table top materials can be a source of such interference, potentially compromising diagnostic confidence.
Why PMI Foam is the Superior Core Material for CT Table Tops
PMI foam is a rigid, closed-cell thermoplastic foam renowned for its exceptional combination of properties, making it an ideal core for advanced carbon fiber CT table tops:
- Exceptionally Low X-ray Attenuation: PMI foam has a remarkably uniform, low-density structure that offers minimal interference with X-rays. This significantly reduces image artifacts, allowing for clearer visualization of anatomy, especially in sensitive areas like the lungs or during low-dose scans.
- Outstanding Strength & Rigidity at Ultra-Low Weight: Patient safety and table stability are paramount. PMI foam provides an extremely high strength-to-weight ratio. This enables the design of rigid, durable table tops that can safely support patients up to 500+ lbs while maintaining precision positioning, without adding excessive weight to the movable table mechanism.
- Superior Dimensional Stability: Unlike some materials that can warp or sag over time and under load, PMI foam maintains its shape and flatness. This ensures long-term table top integrity and consistent performance, scan after scan.
- Perfect for Carbon Fiber Composite Construction: PMI foam is the preferred core material in advanced sandwich panel construction. It bonds seamlessly with carbon fiber skins, creating a structure that is incredibly stiff, lightweight, and radiolucent—the holy grail for CT table design.
Benefits for Clinics and Patients
The adoption of PMI foam-core table tops translates to direct benefits:
- Enhanced Diagnostic Accuracy: Cleaner images lead to more confident diagnoses.
- Improved Patient Throughput: Reliable, stable tables facilitate faster and smoother patient positioning.
- Increased Patient Comfort: The rigidity of the table provides a secure, non-flexing surface during scans.
- Durability & Longevity: Robust construction ensures the table withstands daily clinical use.
For medical imaging OEMs and facilities seeking the pinnacle of performance, specifying a PMI foam core CT table top is a clear choice. It’s an investment in superior image quality, operational efficiency, and ultimately, better patient care.
