Mobile CT scanners are imaging devices designed for mobility. They offer the same diagnostic capabilities as their fixed counterparts but with the added advantage of being easily transportable. These scanners operate on the same principles as traditional CT scanners by using X-rays to generate detailed cross-sectional images of the body. They are typically housed in specially designed trailers or vehicles, making them adaptable to a wide range of clinical scenarios.


Key Features and Components

Mobile CT scanners come equipped with essential features and components, including an X-ray tube, detectors, a patient table, and a computer system for image processing. They are designed to be user-friendly, enabling quick setup and operation in various healthcare environments.


Identifying Your Specific Needs

Selecting the ideal mobile CT scanner for your facility is not a one-size-fits-all endeavor. It requires a comprehensive understanding of your specific needs, constraints, and aspirations.


Facility or Practice Requirements

Mobile CT scanners are versatile and can be employed in different healthcare settings.

  • Hospitals: Hospitals often require CT scanners for emergency situations and to cover imaging needs throughout the facility. High patient volume and diverse cases necessitate versatile and efficient mobile units.
  • Clinics: Clinics typically have a lower patient volume than hospitals and might need a more compact and budget-friendly CT scanner. Efficiency and versatility are still key, but space and budget constraints often come into play.
  • Mobile Units: These units are often used in remote or underserved areas, offering diagnostic imaging capabilities on wheels. Space and mobility constraints are more significant in this scenario, as the unit must be easily transportable.


Patient Volume and Case Types

Your facility’s patient volume and case types impact what capabilities the chosen mobile CT scanner needs to possess.

  • High Patient Volume: If your facility sees a high number of patients daily, you’ll need a scanner with quick image acquisition and a streamlined workflow. Multislice scanners are often preferred in this scenario.
  • Case Types: Consider the cases you’re handling. If you frequently deal with complex cases like cardiac or neurological imaging, a scanner with high resolution and specialized imaging modes might be necessary.


Space and Mobility Constraints

Your facility’s physical layout and space also influence your choice.

  • Space Constraints: In smaller clinics, space might be limited. Compact or portable mobile CT scanners could be more appropriate for such.
  • Mobility Constraints: If you operate a mobile unit, your scanner should be designed for mobility and quick deployment.


Regulatory Requirements

Healthcare regulations are stringent. Regulatory bodies like the Food and Drug Administration (FDA) govern the use of medical equipment, and your chosen scanner must meet these requirements.


Types of Mobile CT Scanners

Not all scanners are created equal; their differences impact efficiency, patient care, and radiation safety.


High-Resolution vs. Low-Dose Scanners

High-Resolution Scanners

  • Applications: High-resolution scanners excel in areas such as cardiac imaging, neuroimaging, and detailed anatomical assessments.
  • Image Quality: These scanners produce images with exceptional clarity and fine details, making them perfect for complex diagnostic tasks.
  • Radiation Dose: They may deliver a higher radiation dose compared to low-dose scanners, so careful dose management is essential.


Low-Dose Scanners

  • Applications: Low-dose scanners are well-suited for routine diagnostic imaging where high radiation doses aren’t necessary.
  • Patient Safety: They are the preferred choice for pediatric, routine screenings, and scenarios where minimizing radiation exposure is critical.
  • Image Quality: Image quality is good, although not as detailed as high-resolution scanners.


CT Scanner Slices

When choosing a CT scanner, one of the early specifications that come up is the number of slices. In the second-hand market, CT scanners with slice counts of 16, 32, 40, 64, and 128 are commonly available. More recently, 256 and 320-slice CT scanners have also become available. Systems with 4 and 8 slices are still in the market but are being phased out.


The number of slices in a CT scanner significantly impacts the time it takes to perform a CT scan. Higher slice counts offer reduced scan times, higher patient throughput, lower radiation doses, and more detailed images with fewer artifacts. Additionally, CT scanners with higher slice counts offer options for advanced imaging, such as cardiac exams. However, a higher number of slices also means a higher price.


Therefore, when deciding on a CT slice count, you should balance your clinical needs, patient flow targets, and budget. Doing so lets you determine the most appropriate slice count for your facility.



The major brands of CT scanners are Toshiba (now known as Canon Medical), Siemens, GE, and Philips. All of them have a long-standing reputation for providing high-quality CT scanners, and their used systems hold a high value. You may have a personal preference for a particular brand, so consider this also in choosing the CT scanner for your facility.
