Description

X선 진단장비의 구동 방법How to run X-ray diagnostic equipment
본 발명은 X선 진단장비의 구동 방법에 관한 것으로, 보다 구체적으로 C-암(C-arm)을 구비한 X선 진단장비를 이용하는 X선 촬영 방법에 관한 것이다.The present invention relates to a method of driving an X-ray diagnostic apparatus, and more particularly, to an X-ray imaging method using an X-ray diagnostic apparatus having a C-arm.
C-아암을 구비하는 X선 진단장비는 인체 및 동물 몸체의 환부를 엑스레이 촬영하여, 지속적으로 환부에 대한 영상을 획득함으로써, 획득한 영상을 판독하여 진단할 수 있는 장비로서 널리 알려져 있다. C-아암을 구비하는 X선 진단장비는 승강용 액츄에이터가 내장된 본체와, 일부분이 절취된 링 형상을 가지며 양단부에 X선 발생장치 및 영상획득장치가 상호 이격 배치된 C-아암과, 아암의 일측으로부터 연장되어 승강용 액츄에이터에 의해 승강하는 아암지지부를 가진다.An X-ray diagnostic apparatus equipped with a C-arm is widely known as an apparatus capable of X-ray imaging the affected part of a human body and an animal body, continuously capturing an image of a diseased part, and reading and diagnosing the acquired image. The X-ray diagnostic apparatus having the C-arm includes a main body having an actuator for lifting and lowering, a C-arm having a partly cut ring shape and having X-ray generating devices and image capturing devices spaced from each other at both ends thereof, And an arm support portion that extends from one side and ascends and descends by the elevating actuator.
본체의 하부에는 본체를 지지하는 베이스가 마련되어 있으며, 베이스에는 본체의 이동이 가능하도록 복수의 바퀴가 장착되어 있다. 아암은 아암지지부의 축선에 대해, 즉 아암지지부의 길이방향에 대해 회전 및 틸팅이 가능하도록 설치되어 있다. 아암 지지부는 아암지지부의 길이방향을 따라 전진 및 후진이 가능할 뿐만 아니라 승강용 액츄에이터에 의해 승강가능하도록 구성되어 있다. 특히, 아암지지부를 아암지지부의 길이방향에 대해 가로로 소정의 위치로 이동시키는 경우, 바퀴의 이동방향을 아암지지부의 길이방향에 대해 가로로 회전시킨 후, 사용자가 본체를 밀거나 끌어 아암지지부를 소정의 위치로 이동시키도록 구성되어 있다.A base for supporting the main body is provided on a lower portion of the main body, and a plurality of wheels are mounted on the base for movement of the main body. The arm is provided so as to be rotatable and tilting with respect to the axis of the arm support, that is, with respect to the longitudinal direction of the arm support. The arm support portion is configured to be able to move forward and backward along the longitudinal direction of the arm support portion, and to be able to move up and down by a lift actuator. Particularly, when the arm support portion is moved laterally to a predetermined position with respect to the longitudinal direction of the arm support portion, the direction of movement of the wheel is laterally rotated with respect to the longitudinal direction of the arm support portion, And moves to a predetermined position.
한편, 이러한 모바일 C-아암 X선 진단장비는 회전하는 아암에 X선 발생장치 및 영상획득장치가 마련되어 있으므로, 인체 및 동물 몸체의 환부에 X선을 촬영할 때 환부의 중심과 영상획득장치의 중심이 잘 일치하여야만 환부의 정확한 영상을 얻을 수 있게 된다.Since the mobile C-arm X-ray diagnostic apparatus includes the X-ray generator and the image acquiring device on the rotating arm, when the X-ray is taken on the affected part of the human body and the animal body, If they are in good agreement, accurate images of the lesion can be obtained.
그런데, C-아암 X선 진단장비는 아암지지부의 길이방향에 대해 가로로 소정의 위치에 아암지지부를 이동시키기 위해 바퀴의 이동방향을 아암지지부의 길이방향에 대해 가로로 회전시킨 후, 사용자가 본체를 밀거나 끌어 아암지지부를 소정의 위치로 이동시킨 후 환부를 촬영하게 된다. 따라서, 환부의 정확한 영상을 얻기 위해 아암 지지부의 미세한 이동이 요구되는 경우, 그 이동에 대한 미세한 조정이 곤란할 뿐만 아니라 아암지지부의 이동시 거친동작으로 인해 환자에게 충격을 줄 수 있는 문제점이 있다. 또한, 경우에 따라서는 환부의 정확한 영상을 얻기 위해서 환부가 영상획득장치의 중심에 일치하도록 환자가 스스로 움직여야 하므로, 특히 거동이 불편한 환자나 중환자의 경우에는 환자의 이동이 곤란하므로 환부의 정확한 영상을 얻기가 곤란한 문제점이 있다.In the C-arm X-ray diagnostic apparatus, the moving direction of the wheel is transversely rotated with respect to the longitudinal direction of the arm supporting portion in order to move the arm supporting portion laterally at a predetermined position with respect to the longitudinal direction of the arm supporting portion, The arm support portion is moved to a predetermined position and then the affected portion is photographed. Therefore, when the arm support portion is required to be finely moved in order to obtain an accurate image of the affected portion, it is difficult to fine-tune the movement of the arm support portion, and there is a problem that the arm support portion may cause a shock to the patient due to rough operation. In addition, in some cases, in order to obtain an accurate image of the lesion, the patient must move itself so that the lesion coincides with the center of the image capturing device. Therefore, in the case of a patient with poor mobility or an intensive care patient, There is a problem that it is difficult to obtain.
특히, 영상을 촬영하는 위치가 다수인 경우 한 곳에서 촬영을 마치고, 다음 위치로 C-아암을 이동시킬 때, C-아암 X선 진단장비의 사용자가 수없이 많은 시행착오를 거쳐서 윈하는 위치로 C-아암을 이동시켜야만 되는 불편함이 있다.In particular, when a plurality of positions for capturing an image are finished, when the C-arm is moved to the next position after finishing the shooting in one place, the user of the C-arm X- There is an inconvenience that the C-arm must be moved.

일반적으로 환자가 받침대, 즉 침대에 누워 있고, 의사는 필요에 의해서 C-아암을 원하는 위치로 움직인 다음, C-아암이 원하는 위치에 놓이게 되면 X선 촬영을 하게 된다. 경우에 따라서, 환자의 여러 부분에 대한 X선 촬영이 필요할 경우, C-아암 X선 진단장비의 사용자는 각 위치마다 C-아암을 움직인 다음 X선 촬영을 해야한다. 그러나, 환자가 침대에 누워 있는 상태에서 그 위로 C-아암을 윈하는 위치로 이동시키려면 많은 조작이 필요하다. C-아암의 움직임이 환자에게 부딛치지 않으면서, 원하는 위치로 C-아암을 움직이는 것이 매우 어렵다.Typically, the patient is lying on a pedestal, bed, and the doctor moves the C-arm to the desired position as needed, and then the X-ray is taken when the C-arm is in the desired position. In some cases, when X-ray imaging is required for several parts of the patient, the user of the C-arm X-ray diagnostic equipment must move the C-arm for each position and then take an X-ray. However, when the patient is lying on the bed and moving the C-arm over it, it takes a lot of work. It is very difficult to move the C-arm to the desired position without movement of the C-arm against the patient.
본 발명은 이 문제를 해결하기 위해서, 자동으로 X선 촬영을 위한 위치로 C-아암을 이동시키면서 X선 촬영을 할 수 있는 방법을 제공한다.In order to solve this problem, the present invention provides a method of performing X-ray imaging while automatically moving a C-arm to a position for X-ray imaging.
도2는 본 발명의 제1 실시예에 따른 C-아암 X선 진단장비의 촬영방법을 도시한 흐름도이다.FIG. 2 is a flowchart illustrating a photographing method of a C-arm X-ray diagnostic apparatus according to a first embodiment of the present invention.
도2에 도시된 바와 같이, 본 실시예에 따른 C-아암 X선 진단장비의 촬영방법은 먼저, 환자에게 필요한 X선 촬영을 위한 위치를 적어도 2개 이상 정하고, 정해진 위치들의 순서를 정한다(S1). 이어서 정해진 순서대로 X선 촬영을 위한 C-아암의 위치를 이동시킬 때의 경로를 정한다(S2). 이동 경로를 정할 때에 환자가 있을 환자영역에는 C-아암의 움직임이 침범하지 않도록 정한다. 이동 경로를 위해서는 이동되기 전 지점의 C-아암의 X 좌표, Y 좌표, Z 좌표, 회전좌표를 구하고, 이동되고 난 이후 지점의 X 좌표, Y 좌표, Z 좌표, 회전좌표를 구하는 것이다. As shown in FIG. 2, in the imaging method of the C-arm X-ray diagnostic apparatus according to the present embodiment, at least two positions for X-ray imaging necessary for the patient are determined and the order of the predetermined positions is determined (S1 ). Then, a path is set for moving the position of the C-arm for X-ray imaging in a predetermined order (S2). When determining the route of travel, the movement of the C-arm should not be involved in the patient's area where the patient is likely to be present. For the movement path, X-coordinate, Y-coordinate, Z-coordinate and rotation coordinates of the C-arm before the movement are obtained, and X-coordinate, Y-coordinate, Z-coordinate and rotation coordinate of the point after movement are obtained.
이동경로는 C-아암이 이동되기 이전의 X 좌표, Y 좌표, Z 좌표, 회전좌표와 이동되고 난 이후의 X 좌표, Y 좌표, Z 좌표, 회전좌표 뿐만 아니라, 두 지점을 이동하는 데 있어서, 어떤 좌표를 먼저 변경시킬 것인지의 순서도 포함된다. 한번에 두개이상의 좌표를 동시에 변경하여 이동하는 것도 포함된다. 이어서, 이동경로에 따라 구해진 좌표를 C-아암 X선 진단장비에 입력한다(S3). 이어서, 환자를 침대에 눕히고, 입력된 경로를 따라서 X선 촬영을 진행한다(S4). The movement path can be used to move the X-coordinate, the Y-coordinate, the Z-coordinate, the rotation coordinate and the X-coordinate, the Y-coordinate, the Z-coordinate and the rotation coordinate after the C- It also includes a sequence of which coordinates to change first. It also includes moving two or more coordinates at the same time at the same time. Subsequently, coordinates obtained according to the movement path are input to the C-arm X-ray diagnostic equipment (S3). Then, the patient is laid down on the bed, and X-ray imaging is performed along the input path (S4).
예를 들어, 어떤 환자에게 다섯군데의 위치에서 찍은 X선 사진이 필요하다고 가정하자. 이전에는 C-아암 X선 진단장비 사용자가 환자를 침대에 눕히고, 첫번째 위치로 C-아암을 움직인 다음 첫번째 X선 사진을 찍었다. 그리고, 다음 위치로 C-아암을 움직여서 고정시키고, 두번째 X선 사진을 찍었다. 첫번째 위치에서 두번째 위치로 C-아암을 움직이는 과정에서 환자가 침대에 누워 있기 때문에, C-아암의 움직임이 환자영역에 침범하지 않도록 해야한다. 또한, 환자의 편의를 위해서는 C-아암의 움직이는 시간을 무한정 늘릴 수도 없다. 따라서 C-아암 X선 진단장비로 다섯 군데에서의 X선 사진을 찍는데 많은 어려움이 있게 된다.For example, suppose you need a x-ray of a patient taken at five locations. Previously, a C-arm X-ray diagnostic equipment user laid the patient on the bed, then moved the C-arm to the first position and then took the first X-ray. Then, the C-arm was moved and fixed to the next position, and a second X-ray picture was taken. Since the patient is lying on the bed in the process of moving the C-arm from the first position to the second position, the movement of the C-arm should not penetrate the patient's area. Also, for the convenience of the patient, it is not possible to increase the moving time of the C-arm indefinitely. Therefore, there are many difficulties in taking X-ray images in five places with C-arm X-ray diagnostic equipment.
그러나, 본 발명에 의해서는 사전에 X선 사진이 필요한 위치의 C-아암의 좌표를 미리 확인하고, 각 위치에서 다음 위치로 이동하는, 환자영역에 침범하지 않도록 경로를 미리 확인하여 C-아암 X선 진단장비에 저장시킨다. 이어서 저장된 데이터에 의해 C-아암을 움직여 X선 사진을 촬영하게 된다. 그러므로, 환자가 일단 침대에 누운 뒤에는 원하는 위치의 X선 사진을 빠른 시간내에 정확하게 촬영할 수 있다. 만약 환자에 필요한 다양한 위치의 X선이 많으면 많을수록 본 발명에 따라 미리 위치 및 이동좌표를 입력시키고, 그에 따라 X선 사진을 찍는 방법을 이용하게 되면 시간을 더 효과적으로 줄일 수 있다.However, according to the present invention, the coordinates of the C-arm at the position where the X-ray photograph is required in advance are checked in advance, and the route is checked beforehand so as not to invade the patient area, Stored in the line diagnostic equipment. Then, the X-ray photograph is taken by moving the C-arm by the stored data. Therefore, once the patient is lying on the bed, the X-ray photograph of the desired position can be taken quickly and accurately. If the number of X-rays at various positions required for the patient is greater, the time and position can be more effectively reduced by inputting the position and movement coordinates in advance according to the present invention and using the X-ray photographing method.
또한, 한번 입력한 좌표 및 경로는 누적하여 저장하여 데이터 베이스화 할 수 있다. 한번 저장한 C-아암의 위치와 이동경로는 메모리에 저장하여, 추후 같은 위치를 움직이는 경우에 사용하게 되면, 좌표 및 이동 경로를 다시 찾을 필요가 없다.In addition, the coordinates and paths once input can be accumulated and stored in a database. The position and the movement path of the once stored C-arm are stored in the memory. If the same position is used later, it is not necessary to search the coordinates and the movement path again.
또한, 본 발명에서는 C-아암이 X선 촬영을 할 위치들을 미리 예정하고, 각 위치들 사이에 이동경로를 미리 자동으로 계산한 다음, 환자에게 필요한 X선 사진의 찍을 위치와 순서만 입력하게 되면, 자동으로 C-아암을 움직여 X선 사진을 찍을 수 있는 C-아암 X선 진단장비의 촬영방법을 제공한다.Also, in the present invention, the C-arm is to predict the positions to be X-rayed in advance, automatically calculate the movement path between the positions in advance, and then only the position and order of taking X- , And a method of photographing a C-arm X-ray diagnostic apparatus capable of automatically capturing an X-ray picture by moving a C-arm.
도3은 본 발명의 제2 실시예에 따른 C-아암 X선 진단장비의 촬영방법을 도시한 흐름도이다.FIG. 3 is a flowchart illustrating a photographing method of a C-arm X-ray diagnostic apparatus according to a second embodiment of the present invention.
도3을 참조하여 살펴보면, 먼저 C-아암 X선 진단장비가 환자영역을 인식한다(S10). 환자영역에 대해서는 가상의 공간을 일괄적으로 입력받을 수도 있고, 환자의 신체특징에 따라 각각 다른 값을 입력받을 수도 있다. 환자영역은 환자의 위치 및 사이즈와, 환자가 놓여 있는 받침대의 크기도 포함한다. 사용자가 미리 손으로 위치를 지정하면 이것을 환자영역으로 인식되게 할 수도 있다.Referring to FIG. 3, first, the C-arm X-ray diagnostic apparatus recognizes a patient area (S10). A virtual space can be collectively input to the patient area or different values can be inputted according to the body characteristics of the patient. The patient area also includes the location and size of the patient and the size of the pedestal on which the patient is placed. If the user specifies the position by hand in advance, this may be recognized as the patient area.
이어서, 환자영역에 대해 C-아암이 X선을 찍을 수 있는 가능한 N개의 위치를 예정한다(S20). 여기서 N개의 위치는 널리 사용되는 환자에게 필요한 X선 촬영을 위한 주요한 모든 위치를 포함할 수 있다. 이어서, 각 N개의 위치에 대한 C-아암의 위치좌표(X 좌표, Y 좌표, Z 좌표, 회전좌)를 지정한다(S20). 이어서, N개의 각 위치중 임의의 한 위치에서 나머지 N-1 개의 위치로 C-아암을 이동하기 위한 경로 값을 지정한다(S30). 이때 이동되는 경로는 환자영역을 침범하지 않으면서도 가장 효율적으로 C-아암이 이동될 수 있는 경로를 선택한다. Then, for the patient area, the C-arm presupposes N possible positions at which the X-ray can be taken (S20). Where the N positions may include all the major positions for radiography necessary for a widely used patient. Then, the position coordinates (X coordinate, Y coordinate, Z coordinate, and rotation left) of the C-arm with respect to each N positions are designated (S20). Then, a path value for moving the C-arm from any one of N positions to the remaining N-1 positions is designated (S30). At this time, the path to be moved selects the path through which the C-arm can be moved most efficiently without invading the patient area.
이어서 환자의 현재 상태에 대응하여, N개의 예정된 위치중에서 임의의 M개의 위치 및 순서를 선택한다(S40). 지정된 순서에 의해, 지정된 이동 경로를 따라서 C-아암은 M개의 X선 촬영을 수행한다(S50).Then, in response to the current state of the patient, any M positions and orders are selected from among the N predetermined positions (S40). According to the designated order, the C-arm performs M X-ray imaging along the designated movement path (S50).
이와 같이, 본 실시예에서는 미리 촬영가능한 위치 및 이동경로를 저장하고, 환자에 따라 원하는 위치 및 순서만 정해지면, 그 정해진 순서에 따라 C-아암이 이동되어 X선 촬영을 하도록 하는 것이다. 따라서, 일일이 환자마다 C-아암 X선 진단장비의 C-아암을 움직이면서 X선 촬영을 하지 않아도 되어, 효율적으로 원하는 X선 촬영을 수행할 수 있다. 또한 경우에 따라 원하는 위치는 같아도 찍는 순서를 다르게 할 경우에도 본 실시예를 사용하게 되면, 효과적으로 X선 촬영을 할 수 있다.As described above, in this embodiment, the position and the movement route which can be photographed are stored in advance, and when the desired position and order are determined according to the patient, the C-arm is moved according to the determined order to perform the X-ray photographing. Therefore, it is not necessary to perform X-ray imaging while moving the C-arm of the C-arm X-ray diagnostic apparatus for each patient, so that the desired X-ray imaging can be efficiently performed. Also, even when the desired positions are the same, but the order of taking the images is different, if the present embodiment is used, the X-ray imaging can be performed effectively.
