CASE DISPLAY APPARATUS, CASE DISPLAYING METHOD, AND STORAGE MEDIUM

摘要

A user input obtainer receives an image movement instruction including identification information specifying a position shift or an image capture time shift to be performed and also including a displacement amount. When the identification information specifies the position shift, a slice position selector determines a tomographic image at a destination of the position shift based on the displacement amount from a set of tomographic images captured at the same time. On the other hand, when the identification information specifies the image capture time shift, the image capture time selector determines a tomographic image at a destination of the shift based on the displacement amount from sets of tomographic images that are identical to each other in terms of a patient, an examination portion, and a modality. A displaying image obtainer reads out the determined tomographic image from an image storage device and gives it to a display information generator.

主权项

1. A case display apparatus, comprising:
a display information generator that generates display information displayed on a display device; a user input obtainer that, when the display information includes a first tomographic image, receives an image movement instruction including identification information and a displacement amount, the identification information specifying a slice position shift or an image capture time shift to be performed; a slice position selector that, when the identification information specifies that the slice position shift is to be performed, determines a second tomographic image at a destination of the slice position shift from a first tomographic image set including the first tomographic image, based on a position movement amount corresponding to the displacement amount, the first tomographic image set being a first plurality of tomographic images; an image capture time selector that, when the identification information specifies that the image capture time shift is to be performed, selects a third tomographic image from a second tomographic image set, the second tomographic image set being a second plurality of tomographic images, a target person of the first tomographic image and target persons of the second tomographic image set being identical, an examination portion captured in the first tomographic image and examination portions captured in the second tomographic image set being identical, a modality for the first tomographic image and modalities for the second tomographic image set being identical, and image capture times of the first tomographic image set and image capture times of the second tomographic image set being different, an image capture time of the third tomographic image being shifted from the image capture time of the first tomographic image based on the time movement amount corresponding to the displacement amount; a displaying image obtainer that reads out the second tomographic image or the third tomographic image from an image storage device, and that gives the read out tomographic image to the display information generator; a different-capture-time image obtainer that obtains a plurality of tomographic image sets from the image storage device, each of the plurality of tomographic image sets being a plurality of tomographic images, persons of the plurality of tomographic image sets being identical, examination portions captured in the plurality of tomographic image sets being identical, modalities for the plurality of tomographic image sets being identical, and image capture times of the plurality of tomographic image sets being different from each other; and an acute disease determiner that calculates a volume of a sick region for each tomographic image set in the plurality of tomographic image sets such that volume of the sick region has an one-to-one correspondence to the tomographic image set, calculates a rate of change with time in the sick region volume based on the calculated volumes and image capture times of the respective tomographic image sets, and determines that the sick region has become acutely worse when the rate of change with time in the sick region volume is equal to or greater than a predetermined threshold value, wherein acuteness information is added to one or more tomographic images stored in the image storage device, the acuteness information indicating that a sick region included in a tomographic image has become acutely worse, and wherein the display information generator generates the display information such that when a tomographic image received from the displaying image obtainer includes acuteness information added thereto, an indicator is added to the tomographic image so as to indicate that the tomographic image includes the acute sick region.
