O Departamento de Física (DF) da UFPE realizará o “Seminário de Óptica” na próxima terça-feira (22). O evento, de título “Photoacoustic tomography: principles, development of a measurement system and its application in dentistry”, acontecerá no auditório do DF, às 4h, e será apresentado pela mestranda do Departamento de Física, Érica Muniz.

Resumo

Photoacoustic (PA) effect consists of the generation of ultrasound waves by a material that has been excited by incident photons. The acoustic waves generated by the sample reveals information about its optical absorption, from which one can development of a non-invasive technique of generating images called Photoacoustic Tomography (PAT). In this study, a new automated PAT system has been developed which is capable of move the sample and saving real-time PA signal directly to the computer for a three-dimensional (3D) scanning of the sample. This preliminary study investigated the applicability of PAT in the diagnosis of dental caries.
