Ultrasound transit time spectroscopy for enhanced medical imaging

Ultrasound imaging is used extensively in a large range of medical applications and currently represents over 25% of all types of diagnostic images produced around the world. Like any imaging modality, ultrasound is negatively affected by factors such as noise and artefacts that reduce the image quality. Phase interference is considered to be one of the key factors affecting spatial resolution. This thesis examined the ability of ultrasound transit time spectroscopy (UTTS) to compensate for phase interference and to improve not only the axial but also the spatial resolution of ultrasound images
