Abstract

PURPOSE:To instantaneously decide the idle state or storage contents of a memory by graphically displaying the data storage state and idle state of the memory, the number of data to be stored, etc., in each data. CONSTITUTION:A measuring equipment 11 executes X-ray CT measurement and a processor 10 enters the measured result, reconstitutes the entered result and displays the stored state or the like of the memory 12 on a graph display device 13. The grasp of the stored state and graphic formation are executed by the processor 10. At the time of displaying the stored state of the memory 12 on a display screen 1, a memory indicating image displays the capacity of the memory by percentage, display parts 20, 21 respectively indicate a using rate and an unused rate and the left lower slash part 3 and right lower slash part 4 of the display part 20 respectively indicate image data storage and raw data storage. Thereby, the data storage order of the memory can be recognized by the display part 20.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a CT display device that displays various types of information.

[Conventional technology]

The X-ray and CT display devices have various types of information such as measurement raw data sent from the measurement system and both CT images. Furthermore, X-ray CT
There are floppy diskettes, optical diskettes, magnetic tapes, data lines, etc. as peripheral devices for the device, and these devices also contain a variety of information. This information is then stored in memory.

In daily work, the operator reads information from these memories, writes information to the memories, edits the information, and so on.

[Problem to be solved by the invention]

In the conventional example, the contents stored in the memory and the amount of storage space are not displayed (1), but are determined by the operator's calculations (0).

Assume that a memory with a capacity of 100 Mbytes currently stores up to 60 Mbytes of data. Therefore, the free area is 40 Mbytes. In this case, conventionally 0.40
The operator is provided with the fact that M bytes is a free area, and since the free area is 40 M bytes, there is room to store 8 data for raw data with a data amount of 5 M bytes. (IQ) Since the free area is 40 Mbytes, there is room to store 20 data for image data with a data amount of 2 Mbytes.However, how this is provided. is given numerically.

Therefore, when an operator wants to store several combinations of one raw data and one image data, it is impossible to immediately determine whether or not to store them.

SUMMARY OF THE INVENTION An object of the present invention is to provide a CT apparatus that allows an operator to immediately determine the empty state of memory and the contents stored therein.

[Means to solve the problem]

The present invention relates to the data storage state and empty state of memory.

We decided to display graphs for each type of data, such as the number of data that can be stored.

[Effect]

According to the present invention, the data storage state of the memory, the free state,
Displays graphs for each type of data, such as the number of data that can be stored.

〔Example〕

1 and 2 are display examples of the present invention. Figure 1 shows
This is an example in which the storage state of the memory is displayed on the display screen 1.

The memory indication screen 2 shows the memory capacity as a percentage, and the display part 20 shows the used percentage 2 The display part 21 shows the unused (empty area) percentage Data (IMAGE) is stored, and the diagonally shaded area 4 pointing downward to the right indicates raw data (RAW DATA) storage. From this display section 20, the data storage order in the memory can be seen. Further, the contents of the instructions on the display units 3 and 4 are also displayed on a part of the screen.

Note that the image data is CT image data, and may be any of XAltCT, positron CT, and NMR images. What is raw data (RAMDATA)?
This is measurement data, and may include data before reconstruction in addition to measured values.

According to this embodiment, the storage state of the memory, the free area, and the details of the storage state can be instantly recognized visually.

FIG. 2 shows another display example. It is a display diagram in various measurement examples with an xgcT device. In X-ray CT apparatuses, there are a 4-second scan method and a 2-second scan method. A 4-second scan is a method that scans the entire 360'' in 4 seconds.
Second scan is a method that scans the entire 360° in 2 seconds.

On the other hand, as an example of classification based on the capacity of image display memory.

There are two types: 512X512 and 320X320.

There are examples of storing data using various combinations of scan time and image display memory capacity.

FIG. 2 shows an example of a graph displaying the number of data that can be stored in such a memory. In addition, in the display example, r4SEC
5CAN+512MATRIXJ shows a display example in which raw data in the 4-second scan method and image data obtained from the raw data are stored together.

Note that the numerical values such as 4 seconds, 2 seconds, 512, and 320 are just examples, and can be applied to other numerical examples.

According to this embodiment, it is possible to immediately know the possible number of measurements for making a future measurement plan for the subject.

FIG. 3 is a diagram showing an embodiment of the CT apparatus of the present invention.

This CT apparatus includes a processing device 10. Measuring device 11° Storage device (memory) 12. It consists of a graph display device 13° and an external interface 14. The measuring device 11 performs, for example, X-ray CT measurement, and the processing device 1o takes in and reconstructs the measurement, and causes the graph display device 13 to display the storage state of the memory 12, etc.

This storage state is grasped and the graph is created from the processing device 10.6 Note that the memory 12 stores raw data from the measurement device 11 and reconstructed images, but in addition to this, raw data from the measurement device 11 and reconstructed images are stored via the external interface 14. External data is also stored.

Furthermore, the processing device 1o performs general data management processing in addition to reconfiguration processing. In addition, the reconstruction process is performed by the measuring device 1
1, but in this case, the processing device 10 is dedicated to data management.

FIG. 4 shows a processing flow for obtaining a display image.

First, the display size per original five image data (one image) and raw data (one raw data) in one measurement mode is calculated (Fl). For example, the width in the horizontal direction and the width in the vertical direction of one hatched area in FIG. 1 are calculated. Next, the storage device (
The contents of the memory (memory) are sequentially searched (F2). Instead of this search, if you have a table that manages the storage order and capacity, you will search for it.

Determine whether the search data is raw data (F3), and if it is raw data, specify its display method (F4); if it is image data, specify its display method (F5). Continue the search until the end (F6) ), and the pattern (F4F6) refers to a downward diagonal line to the right or a downward diagonal line to the left.

FIG. 5 shows a processing flow for displaying free space. First, the amount of free memory space is calculated (Fl). Next, the amount of data for each data combination is calculated (F2). The combination here refers to a combination as shown in FIG. Furthermore, calculate how much of each data combination fits into the free space (F3).
The calculation result is displayed (F4).

Note that 1 display becomes even easier to see when color and gradation display are combined. Furthermore, it can be applied to other than medical data.

〔Effect of the invention〕

According to the present invention, by displaying an easy-to-understand graph display, it is possible to immediately obtain information from the data storage area of the memory. At the same time, it is possible to know the free status, and avoid a bad situation such as insufficient memory capacity during shooting.
