sequence of two parallel threads would have been much better. This quirk inevitably holds back, until after the EMI scanner, all the work of those who had CT in use clinically, albeit with radionuclides, before the prototype X-ray EMI scanner began to be used. It is thoroughly disappointing to see the UK work played down as "also rans", for example the work in Aberdeen is given only half a page...

An X-ray micro-tomography system has been designed that is optimised for low dose imaging of radiation sensitive polymer gels. The scanner is based on a third-generation cone-beam X-ray CT scanner. A mini-focus X-ray source (Oxford XTF5011 or an Oxford series 1500) is used in conjunction with a 100mm diameter X-ray image intensifier (Hamamatsu C7336). The sample may be rotated and moved perpend...

Many industrial manufacturing processes depend on the rapid and accurate measurement of circular objects, for example, pipe, tube and ball and roller bearings, to ensure that the components satisfy the engineering tolerance standards. Despite the importance of these measurements, they are often carried out using time-consuming, manual and randomly sampled procedures. Cross-sectional imaging tec...

I ncidental findings are an important topic in diagnostic imaging. Because of the comprehensive nature of computed tomography (CT) scanning, incidental findings are seemingly found on almost every CT scan performed for a wide variety of reasons in a radiology department. Many of these incidental findings such as a liver cyst are benign and immediately dismissed. Other findings require more exte...
