Moving X-rays to revolutionise the diagnosis of back pain

24.03.2003


A new image processing system devised by engineers at the University of Southampton could change the way that back problems are diagnosed and provide a solution to one of the most common causes of work loss in the UK.


A ’solid model’ of the human lumbar spine



Low back pain is a significant problem and its cost to society is enormous. However, diagnosis of the underlying causes remains problematic despite extensive study. Reasons for this arise from the deep-rooted situation of the spine and also from its structural complexity.

Professor Robert Allen and his team in the Signal Processing & Control Group in the University’s Institute of Sound & Vibration Research are working with colleagues at the University’s Electronics & Computer Science department, The Anglo-European College of Chiropractic, and Salisbury Hospital, to develop a way of X-raying individuals while they are moving, a technique which they believe will improve the diagnosis of back problems by enabling clinicians to quantify how the spine is moving.


‘Up to now, clinicians have frequently used plain X-rays to diagnose back problems,’ comments Professor Allen. ‘These X-rays can only tell you about the spine in a static position, but if we X-ray as the person moves using very low dose radiation, we can see how the spine is moving and with image processing techniques, we can quantify the movement. Since back pain is often caused by soft tissue damage and not damage to the bones themselves, abnormal motion of the vertebrae may help us to locate the source of the problem.’

Their approach is based on automatically identifying vertebrae from the motion image sequences, calculating how each vertebrae moves and coupling this information with a dynamic 3-D lumbar spine visualisation. The traditional approach has been for clinicians to take 2-D images and to form a 3-D impression by mentally transforming these images. Three-dimensional visualisation of the lumbar spine can allow clinicians to observe the lumbar spine from different viewpoints and angles and may be helpful in understanding, diagnosing and treating back pain problems.

Their next challenge is to establish what ‘normal’ movement looks like so that they are in a position to recognise abnormalities.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
