Abstract

Optical tomography is a medical imaging technique which can provide images of haemodynamic parameters and oxygenation at the bedside. Here, we examine two approaches to optical tomography which are intended to provide information about perinatal brain injury. First, we reconstruct static 3D images showing the increase in blood volume and decrease in oxygenation associated with intra-ventricular haemorrhage. Second, we present the first 3D optical tomography images of the whole head during motor evoked responses and show that the peak of activation can be localised to within 11 mm of the estimated position of the motor cortex. © 2005 SPIE and OSA.
