Abstract

Se pueden calcular velocidades de flujo sanguíneo utilizando un análisis de contraste de manchas difusas en dominios espaciales y temporales. En el análisis de dominio espacial, se puede utilizar un sensor de imagen multipixel para detectar una distribución espacial de manchas en una muestra causada por la difusión de luz desde una fuente de luz coherente que es borrosa debido al movimiento de los esparcidores dentro de la muestra (por ejemplo, glóbulos rojos moviéndose dentro de una muestra de tejido). El análisis estadístico de la distribución espacial se puede utilizar para calcular el flujo sanguíneo. En el análisis de dominio de tiempo, se puede utilizar un contador lento para obtener fluctuaciones de series de tiempo en la intensidad de la luz en una muestra causada por la difusión de luz en la muestra que es suavizada debido al movimiento de los esparcidores. Se puede utilizar el análisis estadístico de los datos de series de tiempo para calcular el flujo sanguíneo.
