Abstract

PURPOSE:To grasp the position of an apex or a whole shape by generating and displaying a pattern having a length corresponding to the size of an inclination in the direction of the inclination from the position of the largest data at every cell. CONSTITUTION:First of all, cells consisting of a pair of intensified data of four points on a rectangle from a data memory 2 are read out in order. And a display segment coordinate arithmetic unit 3 performs the calculations of equations I and II against the pairs of the intensified data D11, D12, D21 and D22, to find a coordinate position (x1, y1). A line segment generator 4 generates a line segment between the coordinate position and the coordinate position having the largest data out of the four points of intensified data, and writes it on a graphic memory 5, to display it on a graphic display 6. The line segment is constituted so that the steeper the inclination, the longer is the length, and at a portion corresponding to a ridge, the line segment is displayed from a higher data position out of both sides of the cell, and therefore, the status of the whole of data can be grasped.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a two-dimensional intensity method that sequentially reads out matrix-like two-dimensional intensity data to generate and display line segments that allow the peak apex and overall shape to be grasped. This relates to a data slope display method.

(Prior Art) Matrix-shaped two-dimensional intensity data obtained by an analyzer includes two-dimensional NMR (nuclear magnetic resonance) data, temperature distribution data obtained by two-dimensional scanning, and other various data. When analyzing such data, a contour map is used to understand the apex of the peak and the overall shape.6Contour maps are used to store two-dimensional data obtained by an analyzer in a storage device. After that, the height of the isoshoulder line is compared with the individual data read from the storage device, and the data with the value closest to that height is selected. Techniques such as drawing iso-shoulder lines by connecting the data positions 1 are used.

[Problem that the invention seeks to solve]

However, with the above method of grasping the apex and overall shape of the peak using iso-shoulder lines, it is necessary to draw many iso-shoulder lines at numerous heights (thresholds). spending a lot of time. In addition, in order to draw the isoshoulder line, a comparison process is performed in which each piece of data is sequentially read out and compared with the height of the isoshoulder line as described above.
Furthermore, various processes are performed, such as determining and selecting the data with the value closest to the height, and generating line segments, making the processing difficult and complicated, and the overall load on the data processing device is high. This makes it difficult to improve processing speed.

The present invention solves the above-mentioned problems, and allows the apex and overall shape of the peak to be grasped through simple processing.
The purpose of this invention is to provide a method for displaying the slope of dimensional intensity data.

[Means for Solving the Problems] To this end, the two-dimensional intensity data slope display method of the present invention sequentially reads cells each containing a set of intensity data at four points on a rectangle, and displays the position of the largest data and the corresponding position. The present invention is characterized in that the magnitude and direction of the inclination from the position of the largest data are determined, and a pattern having a length corresponding to the magnitude of the inclination is generated and displayed from the position of the largest data in the direction of the inclination.

[Effect]

In the slope display method of two-dimensional intensity data of the present invention, a pattern with a length corresponding to the size of the slope is generated and displayed from the position of the largest data in the direction of the slope for each cell.
A pattern is displayed starting from each of the four cells at the position of data serving as the apex, and in a portion corresponding to a ridge, a pattern is displayed starting from the digit 1 of the higher data in the cells on both sides. Therefore, the position of the vertex and the overall shape can be grasped from the direction of each pattern and how their lengths intersect.

FIG. 3 is a diagram showing an example of displaying two-dimensional intensity data using a tilt display method according to the invention.

In FIG. 1, 1 is a data scanner, 2 is a data memory, 3 is a display line segment coordinate calculator, 4 is a line segment generator, 5 is a graphic memory, and 6 is a graph ink display. It stores two-dimensional intensity data obtained by a magnetic resonance apparatus, etc., and the data scanner 1 reads out the addresses of intensity data (cells) at four points on a rectangle from the data memory 2 to the display line segment coordinate calculator 3. is generated. In this case, the address position, direction, increments, size, etc. may be arbitrary. The 0 display line segment coordinate calculator 3 expresses the slope based on the intensity data of the four points on the rectangle read from the data memory 2. It generates a pattern suitable for, for example, a line segment, and this line segment is
The coordinates of the start point and end point are sent to the line segment generator 4 as a set of coordinates, the line segment generator 4 generates a line segment, writes it into the graphic memory 5, and displays it on the graphic display.

The calculation function in the display line segment coordinate calculation unit 3 basically performs the following calculations on a data set (cell) of four points on a rectangle read from the data memory 2.
From the data memory 2 with the contents shown in t, the intensity data of four points on the rectangle D, D+s, D□,
If we read a cell consisting of the set [)tz, the coordinate position (x+

......(4) Equations (3) and (4) above are used to find the coordinates of the intersection of two straight lines y-A y--x+B. It is defined according to the situation. Therefore, the steeper the slope, the longer the line segment generated from the coordinates determined using this equation. Note that the line segment generation formula is not necessarily limited to the above formula, and other formulas may be used. When line segment i is generated in this way, the four positions of the data that will be the vertices are A line segment is displayed from each cell, and in a portion corresponding to a ridge, a line segment is displayed from the higher data position of the cells on both sides.

Therefore, it is possible to display a diagram that allows the user to grasp the overall status of the data. In addition, if you display this line segment only when each data value of the cell is all greater than or all less than the threshold,
Unnecessary parts for display can be removed.

The part corresponding to the ridge is indicated by <<<, as in part B.
The area around the peak is displayed in the form of >>X<<, such as part 0, and the valley between the peaks is displayed in the form of <>, as in part D. FIG. 3 (bl) shows an example in which iso-shoulder lines are further superimposed on the display contents of FIG.

Note that the present invention can be modified in various ways, and is not limited to the above embodiments. For example, by identifying parts A, B, 0, D, etc. shown in FIG. Marks such as Δ may be displayed at the vertices, or special patterns, shapes, and shading may be added to the vertices to make it easier to see the overall shape and characteristic positions of the 'ζ data.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the direction and magnitude of the inclination can be displayed using line segments, so the apex of a peak, ridge, valley line, etc. can be expressed by a combination of characteristic line segments. It becomes easier to understand the overall shape of the data. Furthermore, since each line segment is generated by processing on a cell-by-cell basis, processing and output times can be shortened, and necessary information can be obtained in a short time. Furthermore, the data can be easily and quickly identified and analyzed by superimposing the display with a commonly used display such as a contour map.
