Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a scale display device that displays a scale on the same screen E for visually measuring the length of an arbitrary part of an image displayed on the screen of a display means. It is something.

[Technical Background of the Invention and its Problems] Conventionally, when measuring the length of an arbitrary part of an image displayed on the screen of a display means, for example, a region of interest, the length can be measured by specifying two points at which the length should be measured. The measurement results were displayed on a display means in the form of text or the like. Although such a method is useful when it is necessary to know an exact value, it may be inconvenient in some cases. This will be explained below.

FIG. 4 is a diagram showing a method of measuring a predetermined length of a region of interest using a conventional scale display device.

As shown in the figure, according to the conventional device, in order to measure the length, it is necessary to specify two points (P^, Pa) at both ends. However, with this method, when measuring continuously at different locations, it is time consuming and extremely complicated. Furthermore, since the measurement results are displayed in letters or numbers, it is not possible to intuitively determine whether the measurement results are good or bad, which is inconvenient when diagnosing the affected area.

[Object of the Invention 1] The present invention has been made in view of the problems of the above-mentioned conventional devices, and it is an object of the present invention to provide a display device suitable for diagnosis.

[Summary of the Invention 1 The permanent invention comprises an image display means, and an external input means for transmitting setting information of the position, direction, length of the line segment to be displayed on the display means, and the scale interval of the line segment. and control/processing means for setting line segments having scales at arbitrary intervals at arbitrary positions on the display means based on each setting information from the external input means.

[Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a scale display device according to an embodiment of the present invention. Reference numeral 1 indicates an external input means (track 2 is a control/processing means that inputs information from the external input means 1 and performs predetermined arithmetic processing to be described later. 3 is a storage means, and control/processing means 2
It has a built-in control program for performing predetermined calculations and processing. Reference numeral 4 denotes a display means (display) for displaying a scale based on the output information of the control/processing means 3.

Next, the operation of the scale display device according to the embodiment will be explained with reference to the first embodiment shown in FIG.

First, in step 1, by operating the external input means 1, a line segment of a constant length, which is the basis of a scale, is marked with a scale at a predetermined interval (for example, 5 mg+) by operating the display means 1. The calculation for marking the scale is controlled and
The processing is performed by the processing means 2 as follows. By operating the external input means 1, any two points (P^, P
s) is specified, P^ (×^, Y
The length L(ffll>) between ^) and Pe(xe, ve) is calculated.

1-=...(1) l: Length conversion value per 1 dot (m+n/dot) Next, based on the length, the scarcity is determined by formula (2).

...(2) The above deficiency and the following formula (3-1),
(By formula 3-2, any scale point Pn-(xn, vn) at an interval of 511 m based on the point P^ (XA, Y^)

3-2) α: Angle between the X-axis and the line segment For example, the coordinates of the point P^ at the end of the scale in Figure 3 are (×^, Y
^) and the next scale point P! - coordinates are (5cos
7m +x A, 5Sin /I! l +V^), the coordinates of the next scale point P2- are determined one after another, and a scale is displayed on the screen of the display means 4 at the corresponding coordinate position (step 3). If the scale setting is not completed (step 4), the process returns to step 2, but when it is completed, the process proceeds to the next step.

In the next step 5, the position and direction of the graduated line segment are set by operating the external input means 1,
It moves to a predetermined position on the screen based on the setting information (step 6). If the position movement is not completed (step 7), the process returns to step 5, and when the position movement is completed, all steps are completed.

In the embodiment, the interval between the scales is set to 5 mm, but the interval is not limited to this, and a predetermined interval can be set, and various modifications are possible within the gist of the present invention.

[Advantageous Effects of the Invention 1] As explained above, according to the present invention, a scale for measuring an arbitrary length of a region of interest can be easily and quickly set at an arbitrary position, in an arbitrary direction, and at an arbitrary length. Therefore, continuous measurement of the length of each region can be easily and quickly performed. Therefore, it is also possible to facilitate and speed up diagnosis of the affected area.
