Provided are an imaging unitthat uses a light emitted from a second beam splitterof a microscopethat can use an exciting light and an observation light, which is a light including a wavelength other than that of the exciting light, as a light source by switching there between and is provided with the second beam splitterto image images of the same observation region of the microscopein situations where the exciting light and the observation light are used as the light source and an output unitthat overlaps, synthesizes, and outputs the images imaged by the imaging unitrespectively using the exciting light and the observation light as the light source.

Observation assisting device, information processing method, and program

The disclosure provides technology for analyzing video data of a fluorescent contrast agent shot by a microscope during an operation, and provides a method and system allowing information such as BV, BF and MTT, and vascular wall thickness, to be estimated by fluorescent contrast agent analysis, by applying perfusion analysis methods. The method for processing intravascular hemodynamics images is characterized by shooting video using infrared light, wherein the object of shooting is a portion of a blood vessel injected with a fluorescent contrast agent; performing image analysis of a shape of a chronological change curve of intensity values which are image outputs from the video shooting; and calculating relative data for blood volume and blood flow based on results of the image analysis.

Method and system for image processing of intravascular hemodynamics

Problem: To provide an observation auxiliary device that can appropriately and readily perform observation using an exciting light as a light source. Resolution Means: Provided are an imaging unitthat uses a light emitted from a second beam splitterof a microscopethat can use an exciting light and an observation light, which is a light including a wavelength other than that of the exciting light, as a light source by switching there between and is provided with the second beam splitterto image images of the same observation region of the microscopein situations where the exciting light and the observation light are used as the light source and an output unitthat overlaps, synthesizes, and outputs the images imaged by the imaging unitrespectively using the exciting light and the observation light as the light source.
