About this image

3D reconstructed image of the head and neck of a patient highlighting the blood vessels. The skull and spine are also clearly seen. An iodine contrast agent was injected into the arteries before the patient was placed in a Dual Energy Computer Tomography (DECT) scanner. This takes a series of scans of the patient, a virtual ‘slice’ at two different X-ray energies. The slices can then be combined to form a virtual 3D image and computer processing can apply transparency and colour to the various types of tissue. As well as its use in clinical diagnosis, this technique is being developed to enable virtual autopsy to be performed on human bodies.
