Apparatus and method of displaying medical images of sliced tissue
First Claim
1. A method of displaying medical images comprising:
- storing three-dimensional time-dependent image data consisting of a plurality of two-dimensional image data collected throughout a sliced tissue in a biological body to be examined by dynamic scanning of a certain time interval;
displaying one of said plurality of scanned two-dimensional image data;
designating a region of interest elongated along a direction on the two-dimensional image displayed;
converting said three-dimensional time-dependent image data to a two-dimensional time-dependent image data having two aces, one axis representing the scanning time, the other axis representing, at each scan, a position in the designated region of interest;
displaying the converted two-dimensional time-dependent image data;
designating a position on the position axis of the displayed two-dimensional time-dependent image;
forming a profile data of the image data values along a line perpendicular to the designated position on the position axis; and
displaying the formed profile data.

Abstract
An apparatus and method are specialized in utilizing a three-dimensional(3-D) time-dependent image data, which is obtained by dynamic scanning in devices such as an X-ray computed tomography device. The dynamic scanning is carried out at a fixed slice layer in a patient body at a certain time interval. When an line-selecting line is set in a 2-D scanned image, a part of the 3-D time-dependent image data, displayed on the TV monitor, the data corresponding to the designated line in the 3-D time-dependent image data can be converted into a 2-D time-dependent image data by an image data conversion unit. The 2-D time-dependent image data is displayed on the monitor and it appears as degrees of density on the screen and shows dynamical image changing with the scanning time. Moreover, when profile-selecting line is designated in the 2-D time-dependent image, a profile forming unit forms a profile data concerning image data values at an axis designated by the profile-selecting line. The profile data is visualized as a time curve on the monitor, and offers a quantitative analysis.
