摘要： Methods and systems for treating a biological fluid with light are disclosed. The methods and systems provide for determining a target light dose for the biological fluid; loading a treatment container holding the biological fluid into an irradiation chamber of an irradiation device comprising: with the treatment container being supported in the irradiation device in between a first array of light sources and first light energy sensors and a second light energy sensor. The first array of light sources is activated, and a first light intensity is measured with the first light energy sensors. A second light intensity is measured with the second light energy sensor, and the first light intensity is compared to the second light intensity to determine an attenuation factor. The attenuation factor is applied to the first light intensity to determine a time to achieve the target light dose, with the first array of multiple light sources being deactivated after the time to achieve the target light dose has elapsed.
