  • Diagnostic X-rays

    A diagnostic X-ray is the oldest and most common medical radiology procedure. Radiologists use X-rays to help diagnose disease or injury inside your body. A machine directs a small, carefully calculated amount of radiation toward a specific part of the body to produce an image on a film on the other side of the body. Radiologists study the X-ray images to detect and diagnose disease or injury.

  • CT dosage

    Computed Tomography (CT) is currently one of the major contributors to the collective population radiation dose due to the increasing popularity of CT examinations as a non-invasive diagnostic tool. The evolution of CT scanner technology has turned their use from specialized into routine examination. More due diligence is required due to the high radiation dose of CT.

  • Where to from here?

    It is of the utmost importance that both clinical justification as well as technical optimization are implemented to maintain a high benefit to risk ratio. Solid interdisciplinary partnerships and research endeavours between clinical specialists and technology engineers will help to fast track developments in this area.

PhD topic:

Front-tracking simulation of red blood cell motion and deformation in microfluidic flows

Details

Several diseases have been shown to alter the flexibility and distensibility of red blood cells. The malaria parasite, which claims the lives of over 2 million people annually, uses the red blood cell as a site for maturation. This considerably affects the mechanical properties of the cell, which loses its ability to undergo significant deformation. Microfluidic devices provide a mean of gaining a better understanding of the behaviour of red blood cells. These involve using fluid flows to exert forces on cells, hence deforming them in a near physiological environment. This project aims to perform numerical simulations modelling the complex fluid dynamics at play in such a microfluidic device. This involves interaction between the fluid flow, the red blood cell membrane and the cytoplasm. This project aims at creating the necessary code for such simulations and elucidating the physics of red blood cells in microfluidic devices.
