  X-ray machines have historically been large and stationary, but portable X-ray devices have become more common, particularly in environments such as nursing homes and field hospitals. They are used to assess fractures, chest infections, and other conditions where imaging is required but patient movement is restricted.
• PET and SPECT Scanners:
  Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT) are advanced nuclear imaging techniques generally performed in specialised facilities. Recent advancements are exploring mobile units for PET and SPECT, particularly to aid in cancer diagnostics and neurological assessments in remote settings.

Key Advantages of Medical Mobile Scanners

Medical mobile scanners offer several unique advantages over their traditional, stationary counterparts:

• Enhanced Accessibility:
  Mobile scanners bridge the gap for patients in remote, rural, or underserved areas, offering diagnostic imaging capabilities that were previously unavailable without travelling long distances. This accessibility helps in the early detection and treatment of diseases, which is critical in improving health outcomes.
• Faster Diagnosis in Emergency Situations:
  In emergency situations, every minute counts. Mobile scanners can be deployed at the scene of an accident or disaster, enabling rapid diagnosis and treatment planning. For instance, portable ultrasound scanners can quickly determine internal bleeding or organ damage, facilitating immediate medical intervention.
• Reduction in Patient Movement:
  For patients with limited mobility, such as those in intensive care units, mobile scanners eliminate the need for transportation to imaging departments. This reduces stress for the patient and minimises the risk of further injury, particularly in cases of severe trauma or instability.
• Cost-Effectiveness for Small Facilities:
  Not all healthcare facilities, especially smaller clinics or rural hospitals, can afford full-scale imaging setups. Mobile scanners present a more affordable alternative, allowing these facilities to provide essential diagnostic services without major infrastructural investment.
• Increased Efficiency in Point-of-Care Diagnostics:
  Mobile scanners support point-of-care testing, meaning that healthcare providers can use them immediately where care is provided. This efficiency reduces patient waiting times, enhances the speed of diagnosis, and contributes to more streamlined workflows within healthcare facilities.

Limitations and Challenges

While mobile scanners provide numerous benefits, they also come with limitations that affect their usability and diagnostic scope:
