Abstract
Provided are a contrast state determination device, a contrast state determination method, and a program that quickly, accurately, and robustly determine a contrast state even in a case where there is an organ that is not included in an image. A plurality of two-dimensional images including information of slice images of a subject at different positions are acquired from a first image series captured before or after a contrast agent is injected into the subject, an index value related to a contrast state is estimated from each of the plurality of two-dimensional images, and the contrast state of the first image series is determined on the basis of each of a plurality of the index values.
Claims14
A contrast state determination device comprising:
- at least one processor;
- and
- at least one memory that stores commands to be executed by the at least one processor,
- wherein the at least one processor
- acquires a plurality of two-dimensional images including information of slice images of a subject at different positions from a first image series captured before or after a contrast agent is injected into the subject,
- estimates an index value related to a contrast state from each of the plurality of two-dimensional images, and
- determines the contrast state of the first image series on the basis of each of a plurality of the estimated index values.
A contrast state determination method comprising:
- a step of acquiring a plurality of two-dimensional images including information of slice images of a subject at different positions from a first image series captured before or after a contrast agent is injected into the subject;
- a step of estimating an index value related to a contrast state from each of the plurality of two-dimensional images;
- and
- a step of determining the contrast state of the first image series on the basis of each of a plurality of the estimated index values.
