Title:Ultrasound and photoacoustic imaging : an atherosclerosis studyen_US
Abstract:Atherosclerosis is the thickening of the vessel wall due to the accumulation of materials. This is a heart condition that strongly relates to sudden cardiac arrest. Since there are almost no symptoms of the growing of plaques until a critical stage is reached, early detection is needed. The biochemical composition of the atherosclerosis plaques may provide information about the severity of their conditions. The wildly used imaging modality, Intravascular Ultrasound (IVUS), provides structural information of the plaques (atheroma) such as the narrowing of the vessel, while functional information such as the lipid pool may not be identified. The use of the photoacoustic imaging (PAI) technique may overcome this obstacle. In this study, the combined use of photoacoustic and ultrasound imaging technique was tested. The result demonstrates that this dual-modality has the potential to become an alternative for atherosclerotic imaging.en_US
