Shielded zoom camera with motion detection function for shield room}

The present invention uses a zoom camera with adjustable magnification (zoom-in/zoom-out) to select a specific area (such as the head or face, heart or abdomen, breathing, etc.) of the patient's body parts set at the correct inspection position. ) relates to a shielded zoom camera for an MRI shield room with a motion detection function that monitors the presence of abnormalities or emergency conditions of a patient during examination while taking pictures.

Accordingly, the designated specific range is the recognition range shown on the monitor screen, and is divided into a 'movement detection shooting zone' in which movement is detected by the designated sector and a 'movement detection shooting zone' in which no movement is detected, and these plurality of The imaging zone is selectively changed through the control module's switching menu (sector switching menu in the program) (using a single zoom camera, but detected by changing the sector designated as the recognition range), and the patient's motion is monitored along with continuous monitoring during the MRI examination. After detecting the presence (moving or floating), an alarm is sent to the examiner through a buzzer, etc. This is to immediately identify or confirm the patient's emergency situation during the test (prevent safety or medical accidents). It is characterized by

In addition, the present invention solves the problem of artifacts (noise, artifacts, or distortion) during shooting (distortion occurs when movement occurs between shooting frames per second or minute - when movement occurs during M.R.I shooting, distortion occurs in the photographed results. By fundamentally eliminating the need for re-taking), readability and testability have been significantly improved compared to before, as well as patient convenience and safety (removing the inconvenience of visiting an outpatient clinic due to re-taking or having to go down from the hospital room to the examination room and back again, and in the case of the elderly and infirm) It is characterized by significantly improving the risk of injury during movement, etc.).

In addition, the present invention, as an optional embodiment, may include a recording function, and is formed so that the monitoring range of the shooting zone can be flexibly changed when shooting using a zoom camera, and information of the pixel value to be detected (fluid or The pixel value of the floating state detection shooting zone) can be adjusted from 1 to 10 (movement is detected by recognizing the change in pixel value, such as how many pixels are moving, for example, whether 10 or 100 pixels are moving). It is characterized by allowing the detection sensitivity to be adjusted while doing so.

In general, the radiation-related work environment is a special work environment with restricted access and takes the form of remote observation and remote work to prevent workers (workers) from being exposed to radiation.

Such remote observation and remote work mainly rely on visual information, and CCTV camera systems are generally used as a visual information source.

However, the conventional monitoring camera system is for simple recognition (including monitoring-zoom cameras) to determine the movement of the patient entering the examination equipment, and there is no method for immediately confirming the patient's movement during filming.

To elaborate, patients who enter MRI equipment or CT equipment for examination are required to accurately determine (read) the condition of the area to be examined (head, face, heart, or abdomen, breathing area, etc.). Lie down in a fixed state.

At this time, the patient must lie in the stuffy tunnel for a considerable amount of time (approximately 30 minutes) while maintaining an upright posture and listening to the roar of the testing equipment. If the patient moves even for a moment due to itching, itching, or frustration, no images are taken. Distortion occurs in the video frame being processed, eventually making it impossible to read.

Such poor imaging causes loss by wasting time and energy, especially the difficulty of re-imaging for patients with limited mobility (resulting in hospitalization or re-call of outpatients as well as inpatients in the hospital, resulting in resentment from patients). It is encouraged.

In addition, in the existing case, if movement occurs during filming for inspection, it is not possible to know when and at what point the movement occurred, making it impossible to determine even the re-filming section, which is causing the problem of having to film again from the beginning. .(Problem that the shooting point also changes)

In addition, the existing monitoring cameras were installed simply to check the patient's condition with the naked eye, and during the examination, patients (traffic accident patients, critically ill patients, intoxicated patients, the elderly, infants, etc.) stopped breathing or lost consciousness. When an emergency situation occurs in which a person cannot breathe (a life-threatening moment), there is no way for workers to confirm this from the outside, so the industry is demanding a solution to prevent unfortunate accidents in advance. .

1. Republic of Korea Patent Publication No. 10-2015-0030816 (published on March 23, 2015)

The present invention is intended to solve the above-mentioned problems, and its technical gist is to use a zoom camera capable of adjusting magnification (zoom in/zoom out) to inspect a specified specific range (head, face, or The purpose is to monitor the presence of any abnormalities or emergency conditions of the patient during the examination while taking pictures of the heart or abdomen (the area to be examined, such as breathing).

The specific range specified above is the recognition range displayed on the monitor screen (a zoom camera is a means of only taking pictures, and when an image taken of a patient is played or displayed on the monitor, the change in pixel value according to the time difference compared to the pixel value selected in the displayed image is displayed). (programmed to detect), it is divided into a 'movement detection shooting zone' that detects movement by a designated sector and a 'moving detection shooting zone' that detects no movement, and these multiple shooting zones are divided into a 'moving detection shooting zone' that detects no movement, and these multiple shooting zones are divided into a 'moving detection shooting zone' that detects movement by a designated sector. By selectively changing the menu (sector change menu in the program) (using a single zoom camera, but detecting by changing the sector designated as the recognition range), the patient's presence or absence of motion (moving or floating) is monitored along with continuous monitoring during the MRI examination. After detection, an alarm is sent to the examiner through a buzzer, etc., and the purpose of this is to provide immediate identification or confirmation of the patient's emergency situation during the examination (prevention of safety or medical accidents).

In addition, the present invention not only prevents safety accidents for patients, but also prevents the problem of artifacts (noise, artifacts, or distortion) during shooting (distortion occurs when movement occurs between shooting frames per second or minute - during MRI shooting). By fundamentally eliminating the problem that movement causes distortion in the imaged results and requiring a retake, the readability and testability are significantly improved compared to the previous version, as well as the patient's convenience and safety (from the outpatient visit or hospital room to the examination room due to reimages). The purpose is to provide a significant improvement in reducing the inconvenience of having to go down and come back up (and in the case of the elderly, the risk of injury during movement, etc.).

In addition, the present invention, as an optional embodiment, may include a recording function, and is formed so that the monitoring range of the shooting zone can be flexibly changed when shooting using a zoom camera, and information of the pixel value to be detected (fluid or The pixel value of the floating state detection shooting zone) can be adjusted from 1 to 10 (movement is detected by recognizing the change in pixel value, such as how many pixels are moving, for example, whether 10 or 100 pixels are moving). The purpose is to provide a way to adjust the detection sensitivity while doing so.

In order to achieve this purpose, the present invention is installed so that the camera lens is pointed toward the side facing the entrance and exit of the MRI equipment or CT equipment in the shield room (the initial part where the patient enters the equipment while lying down), so that the loading table is installed. A zoom camera 100 that, when the position is set at the exact examination position, takes pictures of a designated specific range of the patient's body (check area: the area to be examined, such as the head, face, heart, or abdomen, breathing); By adjusting the magnification (zoom in/zoom out) of the zoom camera, it is possible to monitor the patient's condition and detect whether or not the patient moves during the examination. However, the sector designated as the recognition range (movement detection zone where movement is detected and detection of no movement) A control module 200 that immediately guides (outputs) the detected signal through an alarm (sound, buzzer, luminescent lamp, etc.) when the presence or absence of motion (moving or floating) is confirmed according to the floating detection shooting zone; It is composed and made.

Accordingly, the sector designated as the recognition range in the control module 200 is divided into a floating detection shooting zone (A) in which movement is detected and a floating detection shooting zone (B) in which no movement is detected. The floating detection shooting zone can be selectively changed through the conversion menu (using one zoom camera, but sensing is detected by changing the sector designated as the recognition range), allowing one zoom camera 100 to monitor and detect motion. do.

At this time, when the presence or absence of movement (moving or immobility) is confirmed, the control module stops the operation (capturing) of the MRI equipment or CT equipment and connects it so that new or subsequent images can be taken just before the movement occurred. It is desirable to be

Accordingly, it is desirable for the control module to have a recording function added depending on selection.

In this way, the present invention has the effect of monitoring the presence of abnormalities or emergency conditions of the patient during the examination while photographing a specified specific range of the patient's body parts set at the examination position using a zoom camera with adjustable magnification. .

The specified specific range is a recognition range shown on the monitor screen, and is divided into a 'movement detection shooting zone' in which movement is detected by the designated sector and a 'movement detection shooting zone' in which no movement is detected, and a plurality of these shooting The zone can be selectively changed through the switching menu of the control module and continuously monitors during the MRI examination, detects the presence or absence of the patient's motion, and then alerts the examiner through a buzzer, etc. This allows the patient's emergency situation during the examination. It has the effect of allowing you to immediately understand or confirm.

In addition, the present invention not only prevents safety accidents for patients in advance, but also fundamentally eliminates the problem of artifacts during imaging, significantly improving readability and inspection compared to the past, and greatly improving patient convenience and safety. There is an effect.

In addition, the present invention, as an optional embodiment, may include a recording function, and is configured to flexibly change the monitoring range of the shooting zone when shooting using a zoom camera, and information on the pixel value to be detected is 1 to 1. It has the effect of allowing the detection sensitivity to be adjusted by adjusting it to 10 levels.

Figure 1 is an example of a shield room in which a shielded zoom camera for an MA shield room with a motion detection function according to the present invention is installed;
Figure 2 is an example showing monitoring of a flow sensing shooting zone using a zoom camera and control module according to the present invention;
Figure 3 is an example showing monitoring of a floating detection shooting zone using a zoom camera and control module according to the present invention;
Figure 4 is another embodiment of the present invention, which is an example showing that the area of the sector designated as the recognition range (the floating detection shooting zone where movement is detected and the floating detection shooting zone where no movement is detected) can be adjusted.

Next, the present invention will be described in more detail with reference to the drawings.

First, as shown in FIGS. 1 to 4, the present invention is largely comprised of a zoom camera 100 and a control module 200.

The first function of the present invention is that when motion detection is confirmed, an alarm is generated and the worker or operator is notified through a sound or buzzer, so that the corresponding image can be captured again.

In addition, the second function of the present invention is to detect whether the patient is breathing normally during the test and then detect when the patient stops breathing to prevent safety accidents (brain death, etc.) due to unconsciousness or apnea.

Accordingly, the zoom camera 100 is installed so that the camera lens is pointed toward the side facing the entrance and exit of the MRI or CT equipment in the shield room (the entrance where the patient enters the equipment while lying down).

These zoom cameras have adjustable magnification, and when the loading table is positioned at the exact location for examination, the subject area for examination, such as the head, face, heart, or abdomen, is captured in a designated specific area (check area) among the patient's body parts. ) is formed to take pictures.

Meanwhile, it is desirable for the zoom camera according to the present invention to have a central control structure with a single control method or a plurality of division methods.

It is desirable for such a zoom camera to allow zoom control, image division, image storage, and infrared settings through RS485 communication (wireless control) or room controller (wired control).

Accordingly, the control module 200 is configured to monitor and detect operation while adjusting the magnification (zoom in/zoom out) of the zoom camera.

In other words, the control module sends an alarm (sound, A signal detected through a buzzer, luminous lamp, etc.) is formed to be guided (output) immediately.

At this time, the sector designated as the recognition range in the control module 200 is formed to be divided into a motion detection shooting zone (A) in which movement is detected and a motion detection shooting zone (B) in which no movement is detected.

Accordingly, the floating detection shooting zone and the floating detection shooting zone can be selectively changed through the conversion menu (sector change switch on the circuit) (using one zoom camera, but sensing is detected by changing the sector designated as the recognition range), allowing one zoom The camera 100 is configured to monitor and detect motion.

At this time, when the control module confirms the presence or absence of movement (moving or floating), it stops the operation (filming) of the MRI equipment or CT equipment and stops the examination image recording. When taking a new picture, the control module either starts again from the beginning or It is desirable to link the images so that they can be captured starting from the image immediately before the movement occurred.

In addition, the floating detection shooting zone and the floating detection shooting zone are formed by setting a sensing time so that an alarm is generated depending on the presence or absence of movement during that time.

In other words, the sensing time in the flow detection shooting zone is applied throughout the inspection shooting time, so that if there is no movement and movement occurs even once, an alarm is generated immediately.

On the other hand, the motion detection shooting zone sets the sensing time to about 5 to 10 seconds to capture images of areas where movement is continuously occurring (such as the breathing abdomen or chest), and then detects no movement for about 5 to 10 seconds. This is formed to inform the operator (worker) as an alarm.

In other words, the present invention detects motion and non-motion, and does not detect motion simultaneously (in parallel) with a single zoom camera, but detects motion and non-motion while specifying each sector.

In addition, the control module of the present invention allows setting the range of active sectors and non-active sectors on the monitor, and is formed so that the area of the corresponding range can be adjusted (the sector range can be narrowed or expanded towards the head or heart).

For reference, this sector area is designated at the time of setting, and it is desirable to be able to select either having the sector detection line visible to the naked eye or not visible to the naked eye on the actual monitor.

Accordingly, motion detection according to the present invention is an example, and it is possible to detect whether or not there is motion by comparing it with the immediately preceding video frame.

To explain this in more detail, the specified specific range is the recognition range shown on the monitor screen, and is divided into a 'movement detection shooting zone' in which movement is detected by the designated sector and a 'movement detection shooting zone' in which no movement is detected.

At this time, the zoom camera is a means of only taking pictures, and when the image of the patient is played or displayed on the monitor, it is programmed to detect changes in pixel value over time compared to the pixel value selected in the displayed image.

These multiple shooting zones can be selectively changed through the control module's switching menu (sector switching menu in the program) (using a single zoom camera, but detected by changing the sector designated as the recognition range), along with continuous monitoring during the MRI examination. It is designed to detect the presence or absence of motion (floating or floating) of the patient and then alert the examiner through a buzzer, etc.

In other words, it is characterized by being able to immediately identify or confirm the patient's emergency situation during the examination (preventing safety accidents or medical accidents).

In addition, the present invention solves the problem of artifacts (noise, artifacts, or distortion) during shooting (distortion occurs when movement occurs between shooting frames per second or minute - when movement occurs during M.R.I shooting, distortion occurs in the photographed results. By fundamentally eliminating the need for re-taking), readability and testability have been significantly improved compared to before, as well as patient convenience and safety (removing the inconvenience of visiting an outpatient clinic due to re-taking or having to go down from the hospital room to the examination room and back again, and in the case of the elderly and infirm) (risk of injury during movement, etc.) is greatly improved.

In addition, the present invention, as an optional embodiment, may include a recording function, and is formed so that the monitoring range of the shooting zone can be flexibly changed when shooting using a zoom camera, and information of the pixel value to be detected (fluid or The pixel value of the floating state detection shooting zone) can be adjusted from 1 to 10 (movement is detected by recognizing the change in pixel value, such as how many pixels are moving, for example, whether 10 or 100 pixels are moving). It is formed so that the detection sensitivity can be adjusted while doing so.

In other words, it is formed so that images can be saved during filming and the condition of the patient being examined can be accurately identified, thereby greatly ensuring medical safety.

The present invention is not limited to the specific preferred embodiments described above, and various modifications can be made by anyone skilled in the art without departing from the gist of the invention as claimed in the claims. Of course, such changes are within the scope of the claims.
