Correcting Magnetic Distortions in MRI Scanners

The shim device comprises a number of coils that produce small magnetic fields which are superimposed on the main magnetic field to correct distortions at the outset of the scan.  Drift and interference can still occur during the scan, but this is resolved by implementing this invention which tracks, and corrects for, the main magnetic field drift.

Correcting for Movement due to Breathing Improves MRI Images of the Heart

Cardiac   Magnetic   Resonance   Image   (MRI)   scanning   lasts for several   heart   beats and as the heart moves with breathing, making high resolution images difficult to obtain.  The algorithm developed enables respiratory motion to be automatically compensated for whilst the patient breathes normally, resulting in timesaving and clear MRI images.

Laxmeter - A Device for Measuring Knee Laxity

The ‘Laxmeter’ facilitates patient support when examining the hip, leg and knee (laxity or total knee arthroplasty) for injury or disease, using X-ray. Stress radiographs form part of the traditional diagnostic methods for knee diseases or injury. Generally stress is created by assistants, resulting in them undesirably being exposed to x-rays.

Biomarkers for Diagnosing Bacterial Vaginosis

UCT researchers have developed a method that will form the basis for point of care test for diagnosing symptomatic and asymptomatic sexually transmitted infections (STIs) and bacterial vaginosis (BV). STIs and BV cause inflammation in the female genital tract increasing their risk of contracting HIV. In resource-limited settings BV and STIs are managed according to signs and symptoms since this is easily implementable, relatively inexpensive and patients are given immediate treatment.
