Abstract
Un método para monitorear una señal de fluorescencia de tiempo variable emitida de un agente fluorescente desde dentro de un medio con propiedades ópticas de tiempo variable se proporciona e incluye proporcionar un conjunto de datos de medición que incluye una pluralidad de entradas de medición que incluyen al menos dos mediciones obtenidas de un paciente antes y después de administración del agente fluorescente. Las mediciones pueden incluir uno o más de: una señal DRex detectada por un detector de luz no filtrado durante iluminación por luz de longitud de onda de excitación de la primera región adyacente al medio de reflejo difuso; una señal de Flr detectada por un detector de luz filtrado durante iluminación por luz de longitud de onda de excitación; y una señal DRem detectada por el detector de luz no filtrado durante iluminación por luz de longitud de onda de emisión. El método además incluye identificar una porción de administración de pos-agente del conjunto de datos de medición; y transformar cada señal de Flr a una señal IF que representa una intensidad de fluorescencia detectada emitida únicamente por el agente fluorescente.
