Abstract: A hologram image of an object is acquired in a state where the object is accommodated in a concave portion provided in a container with a bottom surface of the concave portion being curved. A phase image is generated from the hologram image. Processing of subtracting a phase component derived from a polynomial indicating a shape of the bottom surface of the concave portion from the phase image is performed to acquire a processed phase image.

Abstract: A determination method of non-destructively and easily determining a state of an aggregate of a plurality of cells formed by three-dimensional culture is provided. A determination method according to the disclosed technology includes generating a phase difference image of an aggregate of a plurality of cells from a hologram obtained by imaging the aggregate, deriving a phase difference amount density by dividing a total phase difference amount that is a value obtained by integrating a phase difference amount of each of a plurality of pixels constituting the phase difference image by a volume of the aggregate, and determining a state of the aggregate on the basis of a time transition of the phase difference amount density.

Abstract: A blood flow analysis device includes a blood vessel region extraction unit that extracts a blood vessel region from a three-dimensional medical image of a subject including a blood vessel, and a blood flow simulation unit that obtains a line resistance by multiplying a resistance value corresponding to a branch blood vessel branching out of the blood vessel region by a surface area of each of preset sections into which the blood vessel region is divided in an extension direction, generates a vascular network model by applying the line resistance to each node of a surface of the blood vessel region, and performs simulation of a blood flow by using the vascular network model.

Abstract: Provided is a determination method capable of non-destructively and simply determining a state of a sphere that is an aggregate of a plurality of cells. A phase difference image of a sphere that is an aggregate of a plurality of cells is generated from a hologram obtained by imaging the sphere, and a state of the sphere is determined on the basis of the phase difference image and a shape index value corresponding to a shape of the sphere.
