The first server 450 relays data communication between the first workstation 400 and the central system 500.

The central system 500 includes, as shown in FIG. 4, a second server 510; And a second workstation 550.

The second server 510 relays data communication between the second workstation 550 and the remote system 400.

The second workstation 550 analyzes image data transmitted from the first workstation 410 in real time through the first and second servers 450 and 510 to filter the detected singularities upon detection of the singularities. Warn the first remote station 410 of the diagnostic station or the diagnostician of the diagnostic station. Here, the diagnoser may be a medical professional and / or a doctor in a diagnostic office.

To this end, the second workstation 550 may include a second data communication unit 551; An image controller 553; A second storage device 555; Specialty notification unit 557; And an alarm transmission unit 559.

The second data communication unit 551 receives image data transmitted from the first workstation 410 in real time through the first and second servers 450 and 510 and supplies the image data to the image control unit 553. In this case, the second data communication unit 551 has the same interface method as the first data communication unit 418 of the first workstation 400.

The image controller 553 analyzes the image data supplied from the second data communicator 551 to detect specificities such as whether the capsule endoscope 200 progresses to the small intestine, the presence or absence of bleeding and disease, and the detected specificity. A notification signal for filtering the matter is generated and supplied to the singularity notice unit 557. To this end, the image controller 553 may include an image data generator 610 as shown in FIG. 5; A first analyzer 620; A second analyzer 630; And a notification / alarm signal generator 640.

The image data generator 610 reconstructs the image data supplied from the second data communicator 551 in units of frames and stores the image data in the second storage device 555.

The first analyzer 620 determines whether the capsule endoscope 200 has entered the small intestine by using the image data FD, generates a first analysis signal AS1, and supplies the first analysis signal AS1 to the singularity notification unit 557.

In the first exemplary embodiment, the first analyzer 620 may generate the first analysis signal AS1 using time information included in the image data FD. In detail, the first analyzer 620 extracts time information TI included in the image data FD from the image data FD, and compares the extracted time information TI with the first reference value. The analysis signal AS1 is generated. In this case, since the capsule endoscope 200 is swallowed by the human body and enters the small intestine after about 1 hour and 30 minutes, the first reference value may be set to correspond to 1 hour and 30 minutes. Accordingly, the first analyzer 620 generates the first analysis signal AS1 at a time point when the time information TI is equal to the first reference value, and supplies the first analysis signal AS1 to the singularity notification unit 557.

Meanwhile, the first analyzer 620 generates a first analysis signal AS1 by comparing the time information TI with each of a plurality of second reference values set to increase at a predetermined interval from the first reference value, thereby generating a first analysis signal AS1. Supply to 557.

As a result, the first analysis unit 620 according to the first embodiment uses the at least one of the first reference value and the second reference value to determine whether the capsule endoscope 200 has entered the small intestine. It generates and supplies to the singularity notification unit 557.

In the second embodiment, the first analyzer 620 may generate the first analysis signal AS1 corresponding to the type of organ according to the luminance information of the image data FD. In detail, the first analyzer 620 may calculate luminance Yp of each pixel by using red (R), green (G), and blue (B) data of the image data FD as shown in Equation 1 below. The luminance data for each frame is generated using the luminance Yp of each pixel and stored in the second storage device 555. In this case, the first analyzer 620 generates luminance data for each frame by adding the luminance Yp of each pixel, or adds the luminance Yp of each pixel and divides the average luminance divided by the total number of pixels for each frame. Generate data.

Luminance (Yp) = 0.3R + 0.6G + 0.1B

The first analyzer 620 may compare the at least one luminance data of each frame and the luminance data of the current frame stored in the second storage device 555, and the first analysis signal AS1 may be different when the luminance value is rapidly different. Create Here, since each organ such as the stomach, the small intestine, and the large intestine has a different shape and structure, the imaging distance between each organ and the capsule endoscope 200 is different, so that the luminance characteristic of the captured image of each organ is Different organs appear. Comparing the brightness of each of the captured images of the stomach, small intestine, and large intestine captured by the capsule endoscope 200, the brightness of the stomach is the lowest, the brightness of the large intestine is higher than the stomach, The large intestine's brightness is higher than the large intestine.

Meanwhile, the first analyzer 620 may generate a first analysis signal AS1 corresponding to each organ type by comparing the luminance data for each frame with a preset luminance reference value for each organ.

The second analyzer 630 uses at least one of a bleeding pattern and a disease pattern such as cancer, polyps, Ulcer, and erosion using the image data FD. The second analysis signal AS2 is generated by the detection.

In detail, the second analyzer 630 calculates an average red data value of a frame using the red data R value of each pixel among the image data FD and stores the average red data value of the frame in the second storage device 555. In addition, as illustrated in FIG. 6, the second analyzer 630 divides the image data FD into a plurality of blocks to obtain an average red data value, an average green data value, and an average blue data value for each block. The storage device 555 stores the data. Here, each block may have a size of at least 2 × 2. In addition, the second analyzer 630 may shift each block to the right and / or the lower side by one pixel to obtain an average red data value, an average green data value, and an average blue data value of each block. The second analyzer 630 detects the bleeding pattern by comparing the average red data value and the comparison value for each block, and generates a second analysis signal AS2 according to whether the bleeding pattern is detected. Supplies). Here, the comparison value is set to a value larger than 50% of the average red data value of the frame. For example, as illustrated in FIG. 6, the second analyzer 630 compares the average red data value of each block with a comparison value (208.875) larger than 50% of 139.25, which is the average red data value of the frame, and compares the result. The second analysis signal AS2 is generated by detecting a block having an average red data value larger than the comparison value as a bleeding pattern.

On the other hand, the second analysis unit 630 may be configured to the preliminary pathological block data values of red (R), green (G), and blue (B) and red (R), green (G), and blue (B) of each block. ) The disease pattern is detected by comparing the average data values, and the second analysis signal AS2 is generated according to whether the disease pattern is detected. Here, the symptom data value is set to red (R), green (G), and blue (B) data average values of each block analyzed in the frame data of the actual symptom image including the symptom (A) shown in FIG. 7. In detail, the second analyzer 630 may determine a real value between 0 and 1 or 0 according to the similarity between the red (R), green (G), and blue (B) average data values of each block and the pathological block data value. A comparison signal having a real value between ˜100 is generated, and the second analysis signal AS2 is generated by comparing the generated comparison signal with a threshold set according to the diagnoser 600. Here, when the threshold value is set low, the second analysis signal AS2 is frequently generated, but the probability of detecting the condition increases, and when the threshold value is set high, the second analysis signal AS2 is generated less. The probability of detecting the condition becomes low. Accordingly, the threshold value may be set according to the preference of the image reading medical person 600.

The second analyzer 630 may generate the second analysis signal AS2 by analyzing the image data FD supplied from the image data generator 610 on a frame basis, but minimizes detection error and precision. The second analysis signal AS2 may be generated by analyzing a plurality of consecutive frames in order to improve.

The notification / alarm signal generator 640 generates the notification signal WS1 according to the first and second analysis signals AS1 and AS2 supplied from the first and second analyzers 620 and 630, respectively. Supply to notification unit 557.

In detail, the notification / alarm signal generation unit 640 stores the first stored in the second storage device 555 according to the first analysis signal AS1 according to the time information or the luminance information supplied from the first analysis unit 620. The notification signal WS1 including the image and the analysis data corresponding to the imaging data at the time when the analysis signal AS1 is generated is generated and supplied to the singularity notification unit 557. Also, the notification / alarm signal generation unit 640 may analyze the first analysis stored in the second storage device 555 according to the second analysis signal AS2 according to the bleeding pattern or the symptom pattern supplied from the second analysis unit 630. The notification signal WS1 including the image and the analysis data corresponding to the imaging data at the time when the signal AS1 is generated is generated and supplied to the singularity notification unit 557.

In FIG. 4, the singularity notification unit 557 uses the notification signal WS1 supplied from the image control unit 553 through a wired or wireless Internet, including mail, messenger, or text using a mobile terminal. The message is transmitted to the image reading medical doctor 600 in the reading center by using a message, and requests filtering of the detected specificity. Accordingly, the image reading medical person 600 displays the image and analysis data included in the notification signal WS1 or the second work station 550 according to the notification signal WS1 from the specificity notification unit 557. Analyze the image and analysis data displayed on the device 570 to determine whether the capsule endoscope 200 has entered the small intestine of the subject 100, the type of organ, and whether actual bleeding or pathology in the organ of the subject 100 has occurred. The authenticity of the singularity corresponding to the notification signal WS1 is determined, and the authenticity of the first analysis signal AS1 is determined and provided to the image control unit 553 according to the determination result to analyze the image control unit 553. Filter out singularities detected by

Meanwhile, in FIG. 5, the notification / alarm signal generation unit 640 of the image control unit 553 includes an analysis image and analysis data corresponding to the peculiarities according to the filtering result (true determination) of the image reading medical person 600. The alarm signal SW2 is generated and supplied to the alarm transmitter 559.

In FIG. 4, the alarm transmission unit 559 may send an alarm signal WS2 supplied from the image control unit 553 to a mail or messenger including a text, an image or a sound using a wired or wireless Internet, or a text message using a mobile terminal. And the like to be transmitted to the remote system 400 of the diagnosis center or to a diagnosis person in the diagnosis center.

Accordingly, the remote system 400 receives the alarm signal WS2 transmitted from the central system 500 and informs the diagnosis of the reception of the alarm signal WS2 from the central system 500. In this case, the diagnoser may receive the alarm signal WS2 transmitted from the central system 500.

In addition, the diagnoser takes an action corresponding to the received alarm signal WS2. Specifically, the diagnostic endoscope 200 uses an auxiliary method when the received alarm signal WS2 corresponds to a case in which the capsule endoscope 200 does not enter the small intestine of the subject 100 or there is a problem in movement. To proceed to the small intestine of the subject 100 or take measures corresponding to the problem of the movement of the capsule endoscope 200. In addition, when the diagnosed alarm signal WS2 corresponds to bleeding or pathology, the diagnoser performs X-ray imaging of the examinee 100 to accurately determine the position of the capsule endoscope 200. This is because the capsule endoscope 200 is moved by long-term peristaltic movement, and thus the moving distance during imaging, real-time transmission, and analysis is very short, so that the diagnostic person 400 performs X-ray imaging to subsequently perform X-ray imaging. To determine the exact location of the bleeding or disease area. On the other hand, when the subject 100 is active in a place other than a medical institution, the diagnostic person 400 notifies that the bleeding or disease site has been found in the organ of the subject 100, and at the nearest medical institution as soon as possible. By inducing X-ray imaging to be performed, the diagnostic person 400 may determine a more accurate position of a bleeding or diseased area through an X-ray image later.
