In general, CT is a device that cuts the inside of the human body into an image using a rotating X-ray tube and a detector. The images can also record small differences in soft tissues (blood, cerebrospinal fluid, gray matter, white matter, tumors, etc.) that were not visible on normal X-rays, and reconstruct the resulting data to produce three-dimensional images.

In general, CT imaging is different from general X-ray imaging. When a person enters and lie down on a large machine with a cylindrical hole, the X-ray generator takes a picture around the person in a circular shape.

In general X-ray imaging, several images of the front and back are overlapped, while CT imaging is an imaging device that shows a tomographic plane of a certain part of the body, and the X-rays transmitted from various angles of the human body are measured by a computer, It is an imaging equipment that reconstructs absorbed values and displays them as images.

The difference in density between the tiny tissues of the human body can be distinguished using a computer, so it is a test that can not only diagnose the disease but also the composition.

It is configured to.

The display unit 120 displays the result according to the input of the various information and information input through the input unit 110, the CT imaging state and the imaging result so that the experimenter can visually check. Here, the input unit 110 and the display unit 120 may be applied as a single device such as a touch screen, and the input unit 110 and the display unit 120 are collectively referred to as an operation panel 100.

The arithmetic processing module 200 generates a result that is the same as or similar to the actual CT photographing in response to various information input by the experimenter.

The image generating unit 300 generates a preset image to display the result generated by the operation processing module 200 on the screen.

The program memory 400 stores a program for performing the CT simulation method of the present invention. In the present invention, it corresponds to a recording medium storing a CT simulation method.

The data memory 500 temporarily stores temporary data generated during the execution of the CT simulation method of the present invention.

The database unit 600 includes a test condition DB (Database) 610 in which information on various test conditions that can be input by the experimenter is stored in a database, and various test results that can be output corresponding to the test condition input by the tester are databaseized. And a test result DB 620 stored therein.

That is, by analyzing the information on the inspection condition input from the input unit 110 to display various screens for the input of the inspection conditions in the image generating unit 300 on the display unit 120, input to the inspection condition DB (610) The test condition items closest to those of the test condition items are detected, and the test result DB 620 is detected in the test result DB 620 corresponding to the detected test condition items, and the detected test result is calculated. And the inspection result processed by the arithmetic processing module 200 and the inspection result registered in the inspection result DB 620 to extract the closest inspection result, and generate an image corresponding to the extracted inspection result. The resultant image generated by the unit 300 is displayed on the display unit 120. In addition, the central control unit 700 controls the operation state of the program by comparing the login information input through the input unit 110 with login information previously registered in the program memory 400 as necessary.

The operation of the present invention having such a configuration will be described with reference to FIGS. 2 to 4.

When the experimenter clicks on the program, the central control unit 700 loads the CT simulation operation program of the present invention from the program memory 400, and the login unit 120 displays the login screen of FIG. 4A (S101). When the experimenter inputs login information including an ID and a password and clicks the "Login" button, the central controller 700 compares the input login information with previously registered login information in the program memory 400 and determines whether they are the same. (S102). Here, steps S101 and S102 for inputting and comparing login information may be omitted according to a work environment or an experimenter's needs.

If the login information input in step S102 and the pre-registered login information match, the central control unit 700 detects information related to “Start Study” in the program memory 400, and converts the detected information into the image generating unit 300. The display of the "Start Study" screen is displayed on the display unit 120 (S103). In this case, the method may further include displaying past test information before the “Start Study” step (see FIG. 4B).

The "Start Study" step is a step of inputting basic information such as test date, patient number, name, test requestor, patient history, sex, age, weight, and test site (see FIG. 4C), and various input information is input unit 110. ) Is transmitted to the central control unit 700, and the central control unit 700 transmits the input information to the arithmetic processing module 200. The arithmetic processing module 200 calculates information necessary to implement an image before inspection based on the input information, and transmits the arithmetic result to the image generating unit 300. The image generating unit 300 generates a screen as shown in FIG. 4C according to a result calculated by the arithmetic processing module 200 and displays it on the display unit 120.

When the experimenter clicks the "input completed" button, a screen for scout scan ("Scout Scan") as shown in FIG. 4D is displayed (S104), and the experimenter inputs a parameter for the scout scan (S105). ).

The "Scout Scan" step, also called a free scan step, refers to a process of scanning a predetermined range in advance to determine a location to be scanned before performing an actual scan. The "Scout Scan" step is to determine the scout direction for each inspection site, that is, the projection direction so as to scan the side and front images, and the tube voltage (kvp), tube current (mA), scan time (sec), patient posture, This is to set the inspection area, the scan start point and the scan end point, the examination site center point, and the direction in which the patient lies. After entering, click the Start Scout Scan button to start the Scout Scan.

When the Scout Scan is finished, the Scout Scan Result is displayed (refer to FIG. 4E). At this time, the central control unit 700 has a higher rank among various test result data registered in the test result DB 620. The inspection result data that is closest to the basic information input in step S103 is extracted and displayed on the display unit 120 (S106). From the scout scan result image displayed in “Display area” of FIG. 3, the experimenter designates the start point and the test end point to perform the actual test.

If the experimenter designates a start point and an inspection end point to perform the actual inspection from the scout scan result image, the central control unit 700 controls the image generating unit 300 to generate a window for inputting the inspection condition to perform the actual scan (S107). Thus, a screen ("Scan Parameter") for inputting inspection conditions necessary for the actual scan is displayed on the display unit 120 (see FIG. 4F).

When the experimenter enters the test condition (S108) and clicks the scan button (S109), the central control unit 700 compares the input test condition information with the registered test condition information stored in the test condition DB 610 (S110), The inspection result corresponding to the inspection condition closest to the comparison result is detected by the inspection result DB 620 (S111). The detected inspection result is displayed in " Display area " in the operation panel 100 as shown in Fig. 4G (S112) (" Display ").

On the other hand, when the experimenter requests to display a summary screen related to the inspection process and results (S113), the central control unit 700 detects the inspection-related information (test conditions and procedures and results) stored in the data memory 500 and FIG. 4H. A summary screen as shown in FIG. 11 is displayed (S114) ("Summary"). In this case, it is preferable that all data generated in each inspection process are temporarily stored in the data memory 500. Steps S113 and S114 for displaying the summary screen can be omitted for convenience of the experimenter.

Thereafter, when the experimenter clicks the end button (S115), the central control unit 700 controls the screen generation unit 300 to display the screen as shown in FIG. 4I, and displays the currently executing program in response to the user's confirmation button click. Exit ("System off").
