Abstract: An aspect provides an image processing apparatus processing three-dimensional image data generated based on a photoacoustic wave generated from inside of a subject.

Abstract: An image processing apparatus includes a spectral image acquisition unit configured to acquire a spectral image that is an image generated using photoacoustic signals corresponding to a plurality of different wavelengths, based on photoacoustic waves generated by radiating lights with the plurality of different wavelengths to an object into which a contrast agent has been injected, a contrast agent information acquisition unit configured to acquire information about the contrast agent, a region determination unit configured to determine a region corresponding to the contrast agent in the spectral image on the basis of the information about the contrast agent, and a display control unit configured to display the spectral image such that the region corresponding to the contrast agent is distinguishable from a region other than the region corresponding to the contrast agent.

Abstract: An image processing apparatus includes a data acquisition unit configured to acquire, in time series, first image data that have been generated based on acoustic waves generated by irradiating a subject, into which a contrast agent has been injected, with light a plurality of times and that correspond respectively to the plurality of times of light irradiation; and an image generation unit configured to generate second image data indicating a region corresponding to the contrast agent in the plurality of first image data on the basis of the plurality of the first image data acquired in time series.

Abstract: A system includes an image acquiring unit configured to acquire a first image generated by imaging fluorescence that is generated by emitting excitation light onto a subject into which a fluorescent contrast agent has been introduced; and a photoacoustic measuring unit configured to implement photoacoustic measurement by receiving a photoacoustic wave generated in response to light emission onto the subject, wherein the photoacoustic measuring unit is further configured to control the photoacoustic measurement on the basis of the first image.

Abstract: This invention provides illustrations that can be used as educational materials for teaching massage treatment, dermatological therapeutic techniques, dermatological diagnostics, etc.; and methods of performing and teaching massage treatment, based on new anatomical findings about cutaneous blood vessels. The illustrations have a 1st illustration, which displays anatomical characteristics of the skin, including the position and state of the cutaneous veins and valves within the veins. The method of teaching the massage treatment uses the aforesaid illustrations as teaching materials. The massage treatment includes a procedure (A) that comprises pressing, towards their respective plexuses, the thin vessels ascending from the deep dermal venous plexus and/or the subdermal venous plexus, which are formed in the deep dermal layer and/or immediately below the dermis by veins unaccompanied by arteries.
