The histological diagnosis of any intra-thoracic mass by non-invasive techniques remains difficult. Those masses lying near the mediastinum may be accessible to bron-choscopy and biopsy whereas peripheral lesions adjacent to the rib cage are more suited to percutaneous needle biopsy. Computerised Tomography of the thorax provides vital information as to the physical structure and properties of ...

Computed Tomography is a technique that can be performed using a set of X-ray images to re-create a three dimensional dataset which contains information about internal structure. Analysis of multilayered Printed Circuit Boards with their components using this technique allows for the non destructive evaluation of internal layers of failed boards. This report presents the results of computerised...
