Mobile vs. Portable CT: What’s the Difference and Which Do You Need?
Posted on
The right CT system can improve efficiency, expand patient access, and solve logistical challenges, but not all CT scanners are designed for the same situations. Two of the most common options for flexible imaging are mobile and portable systems. While the names sound similar, their capabilities, setup requirements, and ideal use cases are quite different.
We work with healthcare facilities of all sizes to match the right scanner to the right workflow. Here’s a clear breakdown to help you understand how mobile and portable CT scanners differ, and which one could make the biggest impact in your environment.
What Is a Mobile CT?
A mobile CT typically refers to a full-sized, high-performance scanner that is installed inside a dedicated trailer or coach. These systems are designed to be driven to different locations and plugged into external power sources.
Key Features of Mobile CT:
- Standard or high-slice count (often 64 slices and up)
- Installed inside climate-controlled trailers
- Requires ramp or lift for patient access
- Designed for relocation between facilities or sites
-
Often includes shielding and power hookups built into the trailer
Best for:
- Hospitals managing overflow or construction
- Rural outreach programs and remote service areas
-
Temporary imaging solutions while replacing or upgrading in-house equipment
Example from PrizMED:
GE Lightspeed VCT 64 Mobile – A proven workhorse installed in a mobile trailer, ready for deployment across multiple sites. It delivers reliable 64-slice performance for facilities needing full diagnostic flexibility on the go.
Considerations:
Mobile CT requires site prep, such as a dedicated parking pad and power supply. You’ll also need to handle logistics like permitting, trailer access, and patient transport.
What Is a Portable CT?
Portable CT scanners are compact, self-contained units that can be wheeled directly into an exam room or patient bay. They’re designed for maximum flexibility and minimal setup time.
Key Features of Portable CT:
- Lower slice count (commonly 8 to 32 slices)
- Lightweight and mobile within a building
- Often battery-powered or plug-and-play
- Ideal for bedside scanning in ICUs or operating rooms
-
Smaller footprint for use in tight clinical spaces
Best for:
- Emergency departments and critical care units
- Neuro and trauma scanning near the point of care
-
Clinics with limited space or infrastructure for fixed CT installation
Examples from PrizMED:
NeuroLogica BodyTom 32 – A 32-slice, full-body portable CT that brings diagnostic power to the bedside in trauma bays, ICUs, or surgical settings.
NeuroLogica CereTom 8 – An ultra-compact, 8-slice scanner ideal for neuroimaging and time-sensitive stroke protocols.
Considerations:
While convenient, portable CT units may not deliver the same speed or resolution as higher-end mobile or fixed systems. However, they are a game changer for time-sensitive imaging in high-acuity environments.
Mobile vs. Portable CT Comparison Table
| Feature | Mobile CT | Portable CT |
|---|---|---|
| Slice Count | Typically 64+ | 8 to 32 |
| Mobility | Trailer-based, relocates between sites | Wheeled unit, moves within facility |
| Setup Requirements | Parking pad, power hookups, ramps/lifts | Minimal; plug-and-play or battery |
| Best Use | Overflow, outreach, temporary imaging | Bedside, ICU, operating room |
| Image Quality | Comparable to fixed high-end systems | Lower than full-size systems, but adequate for targeted scans |
| Cost | Higher (due to trailer and installation) | Lower (smaller system) |
We Got You Covered!
Both mobile and portable CT systems have their place in modern imaging strategies. The key is knowing how each one aligns with your patient care goals and operational limitations.
