Description

TECHNICAL FIELD The present invention relates to a radiological image simulation system and a method thereof,

The present invention relates to an educational video image simulator system.

Since the discovery of X-rays by Wilhelm Conrad Roentgen in 1895, in the medical field, radiation has been used in medicine to the present day and has greatly contributed to the diagnosis and treatment of patients. In recent years, with the advancement of advanced technology, digital radiographic imaging devices have been developed to perform more accurate diagnosis and treatment. In order to perform radiographic imaging using these advanced radiographic imaging equipment, it is important to nurture human resources who have acquired specialized knowledge.

Medical radiology education is combined with theoretical education to acquire theoretical knowledge and practical training to improve practical skills. In recent years, digitization has made it possible to hold digital radiographic imaging equipment by improving the practice environment. However, in most universities, practical X-ray machines used for educational purposes generate real X-rays and must be practiced using a phantom phantom. Although the use of a phantom phantom is not intended for humans, it is advantageous that there is no radiation exposure. However, high practice can not be expected due to limitation of patient posture in X-ray examination which requires various patient postures according to the examination method.

With the development of modern medicine, many changes are taking place in recent medical education. Among them, medical simulation is the field that has recently begun to attract attention. Simulation can be said to be a way to integrate knowledge and practice by allowing students to experience clinical medical care and crisis situations by bringing students closer to the clinical situation by taking one step further from the previous lecture-oriented education. Simulation is an exercise in which learners can improve their decision making ability and reasoning ability by using a simulator.

Simulator training can be used for mock up and repeated training, so that mistakes can be minimized and realistic techniques can be demonstrated. Because of these advantages, simulation education has been developed in various fields as well as medical field. Radiography Although various forms of simulation training have been developed in the field of education, previous researches on simulation training that can be simulated according to the actual situation using digital method are not enough.

There are 45 radiology departments in Korea at universities in Korea. X-ray equipment for diagnosis is installed and operated in each university's radiology laboratory in accordance with relevant laws and regulations and is being used for the training of students in radiography. Radiology and practical training at each university are organized in the form of intramural practice and hospital practice. Because X-rays are involved in radiography practice, the laboratory is designed to provide radiation protection according to safety management. Because X-ray examination is performed on patients, practicing the patient's posture on the human body can enhance the practical effect in the hands-on training. However, since the actual X-ray is used, a human phantom is used because unnecessary radiation exposure may accompany the human body. In order to construct such a training environment, a photographing room, an X-ray photographing device, a phantom phantom, etc. should be provided, and the photographing room and X-ray photographing equipment should be reported on installation and regularly inspected. In addition, students should wear personal radiation gauges and periodically measure and report them. The use of a human phantom is an alternative to the radiation exposure of the human body, but the whole phantom is expensive, and the partial phantom has limited practicality to implement the patient's posture. Also, even if a human phantom is used, the laboratory environment must be installed and operated in accordance with relevant laws and regulations. Therefore, there is a problem that the cost required for the training room is large and the radiation exposure can not be fundamentally solved.

The present invention provides a training radiation image simulation system capable of overcoming the limitations of practical training using a phantom phantom using a digital radiography system and enhancing safety and safety of radiation exposure without using actual X-rays do. In addition, we propose a system model and a video output algorithm method for implementing a radiological image simulation system.

According to another aspect of the present invention, a training radiation image simulation method is provided. The educational radiological image simulation method comprises the steps of: selecting a region to be inspected for generating a radiological image; selecting a model detector for detecting the position of the patient according to the region to be inspected; selecting an imaging condition of the radiological image; Displaying the user interface, checking errors of the radiographic image simulation based on the selected examination region, the selected radiographic condition and the selected radiological condition, and providing the radiographic image corresponding to the selected examination region, the selected radiological condition, and the selected radiological condition Step < / RTI >

Here, the step of checking the error of the radiation image simulation based on the selected inspection region, the selected photographing condition, and the selected irradiation condition may include checking the sensed value received from any one or both of the model X-ray generator and the model detector, Determining whether the posture of the patient is appropriate based on the region, and determining whether one or both of the selected photographing condition and the selected irradiation condition are appropriate based on the selected examination region.

Referring to FIG. 3, the radiation image simulator system includes a server 300, a model X-ray generator 310, a model stand detector 320, a model table descriptor 330, and a PACS 340.

The server 300 executes the operation software to control the model X-ray generator 310 and provides a result according to the radiation image simulation. The operation software displays a user interface screen on which a user can input a parameter value for operating the model X-ray generator 310, and drives the model X-ray generator 310 according to the input parameter value A control command, for example, an instruction to move the X-ray irradiating unit up and down and / or to the left and right, and the like. In addition, the operating software can retrieve the resultant radiation image in the database according to the input parameter value and display the retrieved radiation image on the display. On the other hand, the operating software determines whether the patient is in the correct posture by using the detector value sensed by the model stand detector 320 and / or the model table de- coder 330 by detecting the posture of the patient and the input parameter value can do. In addition, the operating software may transmit the generated radiographic image to a medical imaging system PACS (Picture Archiving and Communication System) 340.

In one embodiment, the model X-ray generator 310 is connected to the server 300 through a network, and is driven by control of the running software running on the server 300. [ The model X-ray generating apparatus 310 can perform all the operations that the actual X-ray generating apparatus performs in radiographic imaging, such as, for example, moving the X-ray irradiating section up and down and / or right and left. The model x-ray generator 310 includes a camera (not shown), which photographs a patient located in the model x-ray generator 310. The model X-ray generator 310 includes at least one sensor capable of detecting the posture of the patient, at least one sensor capable of detecting the distance between the X-ray irradiating part and the inspection site to be photographed, And may include one or more sensors. The images generated by the camera and / or the device sensing values generated by one or more sensors are transmitted to the server 300 via the network.

In another embodiment, the model X-ray generator 310 is connected to the server 300 via a network, but the image generated by the camera and / or the device sensing value generated by the one or more sensors is transmitted to the server 300 ), But does not include an actuator for moving the X-ray irradiating unit and / or the table by a control command.

FIG. 4 is an exemplary view showing the functional configuration of the operating software of the educational radiological image simulator of FIG. 3; FIG.

4, the operating software 300 may include a worklist module 400, a video output module 410, a video database module 420, an error checking module 430, and a management module 440 have.

The work list module 400 is a module for receiving and processing patient information. A user interface in which the work list module 400 receives patient information is illustrated in FIG. 6 (610).

The image output module 410 receives a parameter value for driving the model X-ray generator 310, and additionally receives a control command for driving the model X-ray generator 310 according to the input parameter value Can be generated. The input parameter values are passed to the image database module 420, the error checking module 430, and the management module 440. The image output module 410 includes an inspection site selection module 411, a detector selection module 412, a photographing condition module 413, and an X-ray irradiation condition module 414.

The inspection site selection module 411 receives an inspection site parameter value for a site to be inspected to generate a radiation image. The inspection sites supported by the radiological image simulator can be layered and managed. For example, the inspection site selection module 411 may display a hierarchical selection menu on the user interface that allows the user to select the inspection site in order of major, minor, and minor categories. In addition, the inspection site selection module 411 may receive a parameter value for the imaging method attitude. The inspection site parameter values input by the inspection site selection module 411 are transmitted to the image database module 420, the error check module 430, and the management module 440.

The detector selection module 412 receives a detector parameter value for selecting a detector to be used in the radiation image simulation. The detector parameter values are passed to the error checking module 430.

The photographing condition module 413 receives the photographing condition parameter values for the photographing conditions of the radiation image. The shooting conditions may be, for example, whether or not a grid is used, a shooting distance, an irradiation field setting, and the like. The photographing condition parameter value is transmitted to the image database module 420.

The X-ray irradiation condition module 414 receives the irradiation condition parameter values for the X-ray irradiation condition to be used for the radiation image simulation. The X-ray irradiation conditions can be, for example, tube voltage (kVp), tube current (mA), irradiation time (sec), tube current amount (mAs) The X-ray irradiation condition module 414 can display the X-ray irradiation conditions, for example, the maximum value and the minimum value of the irradiation amount, according to the inspection region selected by the user.

The image database module 420 stores a plurality of radiation images generated by different parameter values for the same inspection region and provides a radiation image corresponding to parameter values received from the image output module 410 among the plurality of radiation images do. The image database module 420 may include a database output module 421 and an image processing output module 422. The database output module 421 directly outputs the radiation image corresponding to the parameter value, and the image processing output module 422 processes the radiation image according to the parameter value and outputs the image.

For this purpose, the image database module 420 can manage images to be selected according to parameter values for each inspection site. Table 1 shows the image to be selected according to the parameter value when the test site is the hand, and Table 2 shows the image to be selected according to the parameter value when the test site is the pelvis. Here, distance and dose (for example, tube voltage, tube current) were used as parameter values for selecting images. In each table, the DB - format images for outputting the hand and pelvis images were given alphabets according to the Arabic numerals and the dose according to the shooting distance. Thus, each radiological image has a unique identification value. When the corresponding imaging distance and irradiation amount are selected from the user interface, the image of the corresponding density is enlarged or reduced and output.

The error checking module 430 checks errors occurring in the radiation image simulation. The error check module 430 may include a video output check module 431 and an inspection posture check module 432. [

The video output checking module 431 checks the error of the video output condition according to the photographing condition parameter value and the irradiation condition parameter value received from the video output module 410. The video output check module 431 determines whether the photographing condition parameter value selected by the user is appropriate by using the inspection site parameter value inputted by the inspection site selection module 411. [ For example, it is judged whether or not the photographing distance set by the user, the size of the field of view, and the like are appropriate for the selected inspection site. On the other hand, the image output checking module 431 compares the range set as the maximum value and the minimum value of the irradiation amount with the irradiation condition parameter value for the selected inspection site, and determines whether the irradiation condition parameter value is within the set range. If the determination result is within the set irradiation range, the brightness of the radiation image to be output is adjusted or the radiation image having the corresponding brightness is output so as to match the radiation amount selected by the user. If the result of the determination is out of the set investigation range, an error message is output to the user interface.

The inspection posture checking module 432 analyzes the image and the device sensing value transmitted from the model X-ray generator 310 and / or the detector sensitivity value transmitted from the model stand detector 320 / Check the inspection position error. The inspection posture checking module 432 determines whether a detector matching the inspection site selected by the inspection site parameter value is selected. If an inappropriate detector is selected, an error message may be displayed. On the other hand, for example, the inspection posture checking module 432 outputs a video image to a user interface, thereby allowing the user who is performing the radiological image simulation to monitor the suitability of the inspection posture. Also, the inspection posture checking module 432 can determine whether the inspection posture of the patient is appropriate by using the device sensing value and / or the detector sensing value. The judgment result is outputted to the user interface so that the user can correct the posture of the patient.

The management module 440 includes a viewer module 441 for displaying the radiological image, an editing / storing module 442 for editing and storing the radiographic image, a DICOM output module 443 for outputting the DICOM header information of the selected radiographic image, And a DICOM transmission module 444 for transmitting the radiological image to the medical imaging system PACS 340.

FIG. 5 is a flowchart illustrating an operation method of a training radiological image simulator system according to an embodiment of the present invention. FIG. 6 is a flowchart illustrating a method of operating a training radiological image simulator system according to an exemplary embodiment of the present invention, FIG. 7 illustrates an example of a radiological image of a training radiological image simulator system according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 5, in step 500, the user enters or selects patient information. Patient information may be entered or selected through the patient information input window 610 of the main user interface 600 of FIG. The worklist module 400 records the inputted patient information in a memory or a storage device. The patient information can be used as information for identifying the radiation image generated through the subsequent steps.

In steps 510 to 540, the user selects a region to be inspected, a detector, a photographing condition, and an X-ray irradiation condition. The inspection part, the detector, the photographing condition, and the X-ray irradiation condition are set by the detector selection window 620 of the main user interface 600, the grid selection window 630, the inspection part input window 640, ), And the irradiation dose selection window 660. On the other hand, in the case of the inspection site, the inspection site can be selected step by step through the sub-user interface 645. [ The sub-user interface 645 provides a menu for selecting the photographing method attitude 690 in addition to providing the inspection part classified into the large classification 680 and the small classification 685. [ Here, the small classification 685 may be configured to be changed depending on the selected large classification 680.

On the other hand, when a region to be inspected is selected, parameter values that can be selected in the radiography distance selection window 650 and / or the irradiation amount selection window 660 may be changed according to the selected inspection region. For example, the maximum and minimum values may be displayed in the radiation dose selection window 660 and configured to allow the user to select a value within this range, or to output an error message if the parameter value entered by the user is not within this range .

In step 550, when the input of the parameter values through steps 510 to 540 is completed, the error check module 430 checks whether an error has occurred. As a result of the check, if there is a parameter value in which an error has occurred, the process returns to the step of inputting the parameter value to display an error message, and can induce the user to input an appropriate parameter value.

In step 560, if the input parameter values are all values that fall within an appropriate value or an appropriate range, the user presses the shooting button 670. As described above, the model X-ray generating apparatus 310 does not actually generate X-rays, but can output sound produced by the actual equipment when the photographing button 670 is pressed.

In step 570, the image database module 420 outputs the radiation image according to the input parameter value to the user interface. An example of a radiation image to be output is shown in Fig. 7 (a) shows a hand radiographic image (serial numbers 1 to 10 are given) varying in size according to a photographing distance, and a hand radiographic image (serial numbers A to J are given) (Serial numbers 1 to 10 are given) and pelvis radiation images (serial numbers A to J are given) varying in dose depending on the imaging distance. When all of the radiation images corresponding to the combination of the imaging distance and the irradiation amount are provided, the radiation image corresponding to the parameter value is selected and output. In the case where the radiographic images according to the combination of the photographing distance and the irradiation amount are not all provided, the size and the brightness of the existing radiographic image may be adjusted and output.

In order to acquire images using X-ray equipment, it is necessary to actually generate X-rays to examine the subject. On the other hand, in the above-described educational radiological image simulation system, all the inspection procedures are the same as the actual X-ray inspection, but a similar situation can be realized without examining X-rays using sound effects. Since the X-ray is not irradiated, the patient posture can be practiced on real people, and repeated training is possible, which can enhance the practical effect. Also, the image stored in the database can be outputted by the algorithm using the simulation program and displayed on the screen.

It is suggested that training can be performed to enhance proficiency when practicing using the educational radiological image simulation system according to the embodiment of the present invention. First, since the X-ray image is not irradiated, the X-ray image of the educational X-ray system can be repeatedly learned by students and trainees in the field of medical radiology. It can also be free from ethical problems caused by radiation exposure. Secondly, it is possible to implement patient posture free from constraint of patient posture using phantom of human model, and it can expect high practical effect. Third, it can be applied to existing training equipment and model equipment without X-ray tube, which can save cost. Fourth, a variety of images can be converted into a database by updating free images using a web server. Fifth, data exchange between program provider, client, client and client is possible and various case images can be developed. Finally, students can transfer necessary images through mobile terminals and use them for personal learning.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.

It is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents. .
