Computed Tomography

4.5K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

    Area of Science:

    • Medical Imaging
    • Biomedical Engineering
    • Healthcare Technology

    Background:

    • High stroke mortality in Australia is linked to limited access to specialized facilities in rural areas.
    • Current commercial CT scanners are too large and heavy for mobile stroke units (ambulances).

    Purpose of the Study:

    • To design and develop a lightweight CT scanner suitable for mobile stroke units.
    • To improve access to critical stroke care for patients in remote and rural locations.

    Main Methods:

    • Utilized an engineering design optimization approach.
    • Redesigned an existing CT scanner to reduce weight without compromising structural integrity.
    • Employed computer simulations to perform numerous design iterations and reduce costs.

    Main Results:

    • Achieved a three-fold reduction in CT scanner weight.
    • Successfully maintained structural performance of the CT scanner.
    • Reduced overall design costs through extensive simulation.

    Conclusions:

    • The lightweight CT scanner is optimized for mobile stroke unit integration.
    • This medical device offers a scalable solution to improve healthcare equity.
    • Enables timely stroke treatment for patients regardless of their geographic location.
