Description

Practical Evaluation and Education System for Radiologists {Evaluation System for Radiographers ’Training}

The present invention relates to radiological practical evaluation and education system. More specifically, a participant who is taking a practical evaluation of a radiologist or a trainee who is trained in a radiologist trains a real-world evaluation or practice of operating a simulated radiographic apparatus including a model radiation generator, a model detector, and a live-action camera in the first place. Evaluator or practitioner in real time by sending, displaying and storing the result value and photorealistic photograph of the simulated radiography device operated by the evaluator or the trainee in the second place. It is intended to be able to evaluate based on the data stored in the evaluation device even if it is not in real time. More than using a real radiograph It is to help to assess the practical ability to effectively culture or the practical ability.

Radiation, which began with the discovery of X-rays by Roentgen in 1895, has been useful in many fields for a long time until now, and has contributed greatly to the diagnosis and treatment of patients in the medical field. Even in modern times, radiography technology is a big part of the medical field. In particular, recent advances in technology have led to the development of digital radiography equipment combined with digital technology, which contributes to much more accurate and rapid diagnosis and effective disease treatment than ever before.

Training and qualification of a professional man, who has acquired professional knowledge and experience, is of paramount importance for taking radiographic images and performing tests using radiographic imaging equipment. In addition, medical radiology education to cultivate these professionals should be accompanied by theoretical education to acquire theoretical knowledge, and practical education to improve practical skills and accumulate experience. However, there have been many limitations in the problem of preventing the risk because the radiation exposure of the trainees participating in the practice has been a problem in the practice of radiography and diagnostic apparatus. Accordingly, in order to solve the radiation exposure problem for the trainees, alternatives have been proposed and applied to practice using an phantom model made of a human body rather than performing radiography directly.

However, the method using the phantom phantom, there is a problem that can not be expected to have a high practical effect due to the limitation of the patient posture in the radiographic examination requiring a variety of patient posture depending on the test method. That is, since the radiographic examination is for the patient, it is possible to enhance the practical effect by practicing the patient's posture on the same subject as the human body or the human body in the practical education. However, because the human model phantom is a model to the last, various shooting postures cannot be taken, and thus the practice is severely limited. In the case of the whole body phantom, it may have a variety of postures, but most of the phantoms are used in education sites with poor financial conditions, and there are many limitations in implementing the shooting posture like a real patient. There has been a problem that the effect of practice is not great.

In addition, even if there is no direct radiation exposure to the trainees because of the human model phantom, since it is a device that uses actual radiation, it is not possible to completely solve the radiation exposure problem for the trainees participating in the operation of the radiation equipment. Methods have been raised. In addition, since each university's training radiography device uses actual radiation, a separate recording room with strict facility standards should be provided to establish a training environment to prevent radiation exposure. Of course, you should check regularly. In addition, students should wear personal radiometers and make periodic measurements and reports, and conduct annual health check-ups based on occasional importers (enacted in the October 2016 revision of the Enforcement Decree of the Nuclear Safety Act). These points put pressure on continuous training costs for universities, etc., and thus the academic competitiveness is falling back.

On the other hand, the national examination of radiographers who qualify for radiographers is in the form of the first theoretical test and the second practical test. However, in the second practical test, it is not conducted as a practical test dealing with actual radiation equipment, but as a written practical test. Such a practical test is not suitable for objectively evaluating the practical ability that a radiologist must have. Nevertheless, the reason for this is that the proper equipment to conduct the practical test, that is, the device or system for evaluating the radiological test ability without the risk of radiation exposure, has not been developed. I'm doing it. This national examination system focused the direction of the university's instruction on the written practical examination, which made it difficult to cultivate practical on-the-job radiologists. Therefore, graduates have had a problem of being retrained in the field. As a result, the National Institute of Health, the National Institute of Health, introduced the practice test, which was reorganized for the first time in the national examination of physicians, and is preparing to introduce it in the national examination of related organizations. In order to drastically improve the education of radiologists and to cultivate practical human resources required by society, it is necessary to introduce an educational radiography simulator and a radiologist practical examination evaluation system that can improve professional competence and objective evaluation. However, it is difficult to test the actual skills in the practical test because there is no system that can evaluate the practical ability of the candidate for the radiation test qualification without the risk or concern of radiation exposure.

In order to solve the above-mentioned problems, the radiological practical skills assessment and education system according to the present invention can be carried out without the risk or concern of radiation exposure to students who participate in radiological practical skills assessment or trainees who participate in the radiological training program. By providing evaluation and practice conditions that can handle the same radiographer, it enables objective, fair and accurate evaluation of actual practical skills in evaluating radiological practitioners. It aims to provide an environment where it can be done.

In addition to the above-described features, the simulation radiographic apparatus further includes a video camera, wherein the video camera captures an internal image of the first place including the subject, the band patient, and the simulation radiographic apparatus, The communication device is transmitted to the evaluation apparatus through the communication means together with the conversation contents between the band patients, and the evaluation apparatus further includes video / audio output means, and the internal image and the conversation contents are transmitted from the simulation radiographic apparatus. If so, it is also preferable that the radiological practical evaluation and education system further includes a feature of broadcasting the internal image and the conversation contents in real time through the video / audio output means or storing the data in the storage means.

And in addition to the above-mentioned features, the evaluation apparatus further includes reference value calculating means for calculating an appropriate reference value for the evaluation target data, and when the evaluation target data is displayed on the display means, In addition, when storing the evaluation target data and the evaluation result in the storage means, it is also possible to set up a radiological practical evaluation and education system, characterized in that the storage further comprises the appropriate reference value.

In addition to these features, the simulated radiography device includes a simulated device for at least one of X-rays, mammography devices, fluoroscopy devices, angiography devices, bone density imaging devices, CT, MRI or ultrasonography devices.

As described above, the radiological practice practical evaluation and education system according to the present invention performs practical skill evaluation and education only with a simulation radiographic apparatus and evaluation apparatus that does not emit actual radiation, but performs actual skill evaluation by operating an actual radiographic apparatus. The same effect can be achieved with education.

As shown in FIG. 7, the model detector 110 included in the simulation radiographic apparatus 100 may include a first sensor 160a in another embodiment of the radiation history practical evaluation and education system according to the present invention. However, the first sensor 160a measures the height value of the model detector 110, and the height value of the model detector 110 is' an evaluation transmitted by the simulation radiographic apparatus 100 to the evaluation apparatus. It is desirable to be included in the position value included in the object data.

10 is a conceptual diagram of a table type of the simulation radiographic apparatus 100. In the case of the table type, as shown in FIG. 10, the model detector 110 is positioned inside the table 112, and as described above, the model detector 110 is located in the longitudinal direction F in the table 112. Reciprocating movement is possible, and the table 112 is capable of reciprocating movement in the longitudinal direction (G) and the transverse direction (H) on the cradle 113. Therefore, unlike the stand type, the first sensor 160a measures the distance H3 that the model detector 110 moves in the longitudinal direction F of the table 112 from a reference position in the table 112. It is desirable to. In the table 112, a sixth sensor 160a1 capable of measuring how much the table 112 has moved (H4, H5) in the longitudinal direction (G) and the transverse direction (H) from the reference position and It is preferable to include the seventh sensor (160a2). Since detailed descriptions of the second sensor 160b, the third sensor 160c, the fourth sensor 160d, and the fifth sensor 160e are mostly overlapped with the description of the stand type described with reference to FIG. It will be omitted. However, in the table type, unlike the stand type, the SID is measured by the fourth sensor 160d, which means that the model detector 110 is directly below the model radiation generator 120. This is because the vertical distance V2 from the model radiation generator 120 to the model detector 110 measured by the fourth sensor 160d becomes the SID. In the case of the second sensor 160b, the model radiation generator 120 moves along the longitudinal direction B from the reference position instead of measuring the SID which is the horizontal distance from the model detector 110. Distance H1 'is measured.

On the other hand, in the case of the table type, the model radiation generator 120 and the table 112 are each independently reciprocating in the longitudinal direction (B, G) and the transverse direction (C, H) as well as the model detector ( In addition, since the reciprocating movement in the longitudinal direction (F) in the table 112 is possible, the position between the center point of the model radiation generator 120 and the center point of the model detector 110 is relative to each moving distance. Will be different. On the other hand, in order to evaluate a practical ability of an evaluator or a trainee, it is necessary to determine what state the relative position between the center point of the model radiation generator 120 and the center point of the model detector 110 is in. Therefore, for this purpose, the position value transmitted to the evaluation apparatus 200 includes a value between H1 and H5, which are values for absolute positions, between the center point of the model radiation generator 120 and the center point of the model detector 110. It is preferable to include the relative position value of '. In this way, the simulation of the relative position value may be performed by the simulation radiation generating apparatus 100 to be included in the position value and transmitted. It is also possible to include only the absolute value and to allow the evaluation apparatus 200 to calculate the relative position value. Similarly, in the case of the stand type, it is preferable to calculate and apply a 'relative position value between the center point of the model radiation generator 120 and the center point of the model detector 110'.

11 and 12 are system configuration diagrams showing another embodiment of the radiological practical skills evaluation and education system according to the present invention. First, as shown in FIG. 11, the evaluation apparatus 200 included in the radiological practice evaluation and education system according to the present invention further includes a reference value calculating means 250 for calculating an appropriate reference value for the evaluation target data. When the evaluation apparatus 200 displays the evaluation target data on the display means 210, the evaluation apparatus 200 displays the evaluation target data in comparison with the appropriate reference value, and stores the evaluation target data and the evaluation result in the storage means 230. Even if it is preferable to further store the appropriate reference value. Here, the appropriate reference value refers to an appropriate value for normalizing radiographic imaging for an appropriate tube voltage, tube current amount, photographing angle, SID, etc. according to an inspection site, and may be one specific value or a range of values. The reason for causing the reference value calculating means 250 to calculate the appropriate reference value is that the appropriate range of the tube voltage, tube current amount, photographing angle, SID, etc. is changed according to the tube voltage according to the tube voltage. This is because the appropriate range of values may affect each other. When the evaluation apparatus 200 displays the evaluation target data on the display means 210, when the evaluation apparatus 200 displays the evaluation target data in comparison with the appropriate reference value, the evaluators evaluate the evaluator, and the evaluator inputs such as the tube voltage and the tube current amount. Photographing conditions or position values measured by the plurality of sensors 160 can be easily compared with a proper reference value, thereby enabling a fair, accurate and objective evaluation.

In addition, as shown in FIG. 12, the evaluation apparatus 200 further includes an X-ray image DB 260. When the evaluator inputs an image evaluation execution signal through the second input unit 220, the X-ray Among the images included in the image DB 260, it is preferable to select one X-ray image of the inspection site as an image for evaluation and transmit the image to the simulation radiographic apparatus 100 through the communication means 300. In this case, it is more preferable that the simulation radiographic apparatus 100 further includes an X-ray image output means 190. In addition, when the evaluation image is transmitted from the evaluation apparatus 200, the simulation radiographic apparatus 100 may display the evaluation image on the X-ray image output means 190. When the evaluator further includes a configuration for presenting the evaluation image to the evaluator, the evaluator can evaluate not only the manipulation ability of the simulation radiographic apparatus 100 but also the interpretation ability of the photographed X-ray image. It is effective.

As described above, the simulation radiographic apparatus 100 included in the radiological practical evaluation and education system according to the present invention includes an X-ray, a mammography apparatus, a fluoroscopy apparatus, an angiography apparatus, a bone density imaging apparatus, a CT, It is preferable to include a simulation device for at least one of MRI or ultrasonography device, and it is also possible to select one or two or three simulation devices for use in education or practical evaluation, if necessary. It is also advisable to include a simulator of all devices for a comprehensive practical assessment. In the case of the evaluation apparatus 200, one evaluation apparatus 200 may perform training or evaluation performed by all the simulation radiographic apparatuses 100, and each evaluation is performed for each simulation radiographic apparatus 100. It is of course also possible to adapt the device 200.
