Diffuse Optical and PhotoAcoustic Tomography

Workshop on Bioimaging I, Mon, 12 Nov, 2007

Speaker: Simon Arridge

Abstract

Recently there has been considerable increase in interest in tomographic
imaging using light. One method is Diffuse Optical Tomography(DOT) in
which light is detected after transmission through a highly scattering
medium which is described by a diffusion type forward model. Since the
light is detected on the boundary this methodology is usually formulated
as an inverse boundary value problem and is exponetially ill-posed.
More recently PhotoAcoustic Tomography (PAT) uses light to create sound
sources (by heat generated on optical absorption) and image reconstruction
can be done using conventional ultrasound methods.
In this talk I will describe features of each of these methods as well
as attempts to extract further information from the images, such as
scattering cross-section, refractive index and sound speed.
