Porpoise foetus, micro-CT scan. This specimen was collected from a deceased, pregnant Harbour porpoise (Phocoena phocoena) that was stranded as part of the Cetacean Strandings Investigation Programme. Few Cetacean foetuses are available for study and these scans help us to understand their development. The red areas indicate high density material, in this case the enamel on the teeth and ear bones. This image of a harbour porpoise was acquired using X-ray micro-Computed Tomography (also known as micro-CT). A micro-CT scanner projects a beam of X-rays through the sample onto a detector panel. Images are collected over a 360° rotation and these are then reconstructed to form a virtual 3D model of the specimen. This virtual object that can be viewed from all angles and sliced open or digitally dissected. Image by Rebecca Summerfield.
