Abstract: An information processing device that reconstructs an original image including an interference fringe image of at least one object to be observed is provided. The information processing device includes at least one processor that is configured to: acquire local area information representing a local area including the interference fringe image in the original image; generate a reconstructed image while changing a reconstruction position in the local area; calculate sharpness of the reconstructed image each time the reconstructed image is generated and detect an in-focus position where the sharpness is maximized; and output the reconstructed image at the in-focus position as an optimal reconstructed image.

Abstract: There are provided a vascular information acquisition device, an endoscope system, and a vascular information acquisition method that can accurately acquire vascular information on a blood vessel of a target layer that is an object to be measured of a subject. A first blood vessel extraction unit (82) analyzes the image of a target layer to be measured and extracts a blood vessel (first blood vessel) from the image of a target layer. A blood vessel specification unit (84) specifies a blood vessel (second blood vessel) extending to a non-target layer from the target layer. In a case in which the second blood vessel is specified, a second blood vessel extraction unit (83) analyzes the image of the non-target layer in which the second blood vessel is present and extracts the specified second blood vessel from the image of the non-target layer.

Abstract: Using ultrasound frame data generated from the ultrasound echo reflected from the living tissue, the movement amount of the living tissue and its representative value are calculated. In a case where the representative value of the tissue movement amount is equal to or greater than a threshold value, a hue conversion LUT_large having a large degree of hue change is used, and an elastic image in which distortion is expressed by hue corresponding to the magnitude is generated. On the other hand, in a case where the representative value of the movement amount of the living tissue is less than the predetermined threshold value, a hue conversion LUT_small having a small degree of hue change is used to generate an elastic image.

Abstract: Provided are a puncture range determination apparatus and a puncture range determination method in which the hardness of tissue is considered as well as blood vessels. A blood vessel (32) is detected through performing Doppler processing. In addition, a soft region (33) of a subject is detected through performing elastication processing. A range of the soft region (33) excluding the blood vessel (32) is detected as a puncture recommendation range. Guide lines (34) and (35) defining the puncture recommendation range are displayed. A doctor performs puncturing with a needle inside the guide lines (34) and (35) and punctures a puncture target region (31) with the needle.
