Abstract

An image diagnostic device of the present invention includes image display means (16) for displaying a diagnostic image, input means (18) for setting position a plurality of specifying marks on the displayed diagnostic image; and distance measuring means (19) for measuring a distance among the position specification marks which have been set on the diagnostic image.

The image diagnostic device further includes position specification mark supporting means (20) for generating operation support information for setting another position specification mark in accordance with one position specification mark set by the input means (18).

The image display means (16) displays the generated operation support information while correlating it to the diagnosis image.

Claims

1. An imaging diagnostic device comprising:

image display means for displaying a diagnostic image;

input means for setting a plurality of position specification marks on the displayed diagnostic image; and

distance measuring means for measuring the reciprocal distance among the set plurality of position specification marks on the diagnostic image,

characterized in further comprising;

position specification mark supporting means, corresponding to one position specification mark set by the input means, for generating operation supporting information in order to set the other position specification mark,

wherein;

the image display means displays the generated operation supporting information corresponding to the diagnostic image.

2. The imaging diagnostic device according to claim 1, wherein the position specification mark supporting means generates the operation supporting information by setting a candidate for the other position specification mark based on the line segment between the one position specification mark.

3. The imaging diagnostic device according to claim 2, wherein a cursor of the input means displayed on the image display means is displayed distinguishable from the one position specification mark or the other position specification mark.

4. The imaging diagnostic device according to claim 1, wherein the position specification mark supporting means generates the operation supporting information for the purpose of setting a route of the other position specification marks at the position to which the distance is limited in advance from the one position specification mark.

5. The imaging diagnostic device according to claim 1, wherein:

the position specification mark supporting means generates the operation supporting information on the diagnostic image; and

the image display means displays the generated operation supporting information and the diagnostic image simultaneously.

6. The imaging diagnostic device according to claim 1, wherein:

the position specification mark supporting means generates distance information, of the diagnostic image being set in the operation supporting information; and

the image display means juxtaposes and displays the generated distance information and the diagnostic image.

7. The imaging diagnostic device according to claim 1, wherein the position specification mark supporting means sets a limit to the operation range of the other position specification mark within the region of a circle having a previously set distance as a radius, centering on the one position specification mark.

8. The image diagnostic device according to claim 1, wherein the position specification mark supporting means generates an intermediate position specification mark at the position wherein the line segment including the first position specification mark is divided by the previously set split ratio.

9. A measurement point setting method of an image diagnostic apparatus for displaying a diagnostic image on image display means, setting a plurality of position specification marks by moving an position specification mark by input means on the displayed diagnostic image, and measuring reciprocal distance among the set plurality of position specification marks on the diagnostic image by distance measuring means, characterized in including:

a step of setting one point out of the plurality of position specification marks;

a first determination step of determining the feasibility of setting of the one position specification mark;

a step of, in the case that the result of determination is to set the mark, generating a circle having a predetermined radius centering on the one set point, and displaying a display cursor of input means on the generated center point;

a step of moving the display cursor on the image display means, and moving the center of the display cursor along the circumference of the generated circle according to the moving distance of the cursor;

a step of setting another point out of the plurality of position specification marks excluding the one point, at the position to which the display cursor is moved;

a second determination step of determining the feasibility of the setting of the other point; and

a step of, in the case that the result of determination is to set the other point, setting the center point of the display cursor as the other point.

10. The measurement point setting method of the image diagnostic apparatus according to claim 9, wherein the first determination step and the second determination step stand ready at the step thereof until the determination result comes out to set the point.

11. A measurement point setting program of an image diagnostic apparatus for displaying a diagnostic image on image display means, setting a plurality of position specification marks by moving a position specification mark by input means on the displayed diagnostic image, and measuring reciprocal distance among the set plurality of position specification marks on the diagnostic image by distance measuring means, characterized in executing by a computer:

a step of setting one point out of the plurality of position specification marks;

a first determination step of determining the feasibility of the setting of the one position specification mark;

a step of, in the case that the result of determination is to set the mark, generating a circle having a predetermined radius centering on the one set point, and displaying a display cursor of input means on the generated center point;

a step of moving the display cursor on the image display means, and moving the center of the display cursor along the circumference of the generated circle according to the moving distance of the cursor;

a step of setting another point out of the plurality of position specification marks excluding the one point, at the position to which the display cursor is moved;

a second determination step of determining the feasibility of the setting of another point; and

a step of, in the case that the result of determination is to set the other point, setting the center position of the display cursor as the other point.
