As I write this Britain is on the verge of its largest upheaval in the National Health Service since its inception in 1948. I have retained an interest in the provision of health services in Britain not only because, like so many of us, I have worked in the system, both in hospital and in general practice, but also because my elderly mother and stepfather live in Scotland and so provide me with first-hand information about the system - its strengths and its shortcomings. The other reason I am so interested is because we are on the verge of implementing our own National Health Insurance system which, while not exactly the same as the NHS, does have the same ideals, namely the provision of high-quality health care to all, free at the point of service - which, of course, does not mean 'free'. And therein lies the rub.

The question 'What is biomedical engineering?' may elicit a host of answers, the most common of which would usually include mention of the interface between biomedicine and engineering and of the application of engineering principles towards understanding biological systems and improving health.

A well-defined and consistently quantifiable method to monitor fracture healing is not currently available in the standard clinical setting. Evaluation of the stage and rate of healing is important for predicting ability to bear weight fully as well as for identifying fractures that may be affected by delayed or non-union. It is also important to have a reliable and sensitive way to evaluate fracture healing objectively in the research setting, in order to design useful studies for quantitative evaluation of the efficacy of different treatment methods. Digital X-ray combined with image analysis could provide a simple and cost-effective solution to this problem.

An objective, quantitative approach to identifying the facial dysmorphology associated with fetal alcohol syndrome (FAS) would assist screening and surveillance efforts. Such an approach is provided by digital imaging, which is an active area of research for the detection of facial dysmorphology. This paper reviews the use of digital imaging and shape analysis to assess the characteristic FAS facial appearance.

Since the development of magnetic resonance imaging by Paul Lauterbur and Peter Mansfield using a back projection technique in 1973, MRI technology has improved at an unparalleled rate and, due to its exquisite soft-tissue contrast, has become the method of choice for neuro- and spinal imaging. Today a three-dimensional image of the entire brain can be acquired at a 1x1x1 mm3 spatial resolution in just 5 minutes. The true power of MRI, however, lies in its flexibility and the fact that the contrast of images can be manipulated by changing machine parameters in a way that exploits the different magnetic properties of different tissues. Another advantage of MRI over other modalities is the fact that there is no ionising radiation. This makes MRI uniquely suited to research applications where subjects require repeated imaging and to the study of children.

Cardiovascular magnetic resonance imaging (CMR) technology has advanced significantly over the past two decades, and the modality is now being used routinely in radiological investigations. CMR is frequently referred to a 'one-stop shop' for diagnosis as it provides more combined information about cardiac viability, morphology and function than any other imaging modality.

It is estimated that 1 in 4 South Africans will be affected by at least one cancer diagnosis in their lifetime, with breast cancer being the most common cause of death in women. Clinical studies have shown that early detection has caused mortality rates to fall by up to 50%, and the earlier the detection, the greater are the chances of survival. Various medical imaging modalities are used to detect breast cancer, the most common being X-rays (mammography), ultrasound, magnetic resonance imaging (MRI) and various radionuclide techniques. The purpose of this article is to review these and other novel medical imaging modalities.

In 1977 it was first shown that light in the near-infrared region of the spectrum penetrates biological materials sufficiently to measure changes in cerebral oxygenation, a completely non-invasive technique. Since then, near-infrared spectroscopy (NIRS) has been used to monitor oxyhaemoglobin, deoxyhaemoglobin, blood volume and cytochrome oxidase for a variety of clinical and research applications.
