Description

Technical Field

[0001] The embodiments of the present invention relate to the field of CT detection technology, and in particular to a laser calibration and positioning device applied to a CT machine in the medical industry. Background Art

[0002] During the use of the CT scanner bed, the patient's affected part needs to be placed in the scanning center of the CT scanner bed to improve the accuracy of the detection. In order to accurately place the patient's affected part in the center of the CT scanner bed, the patient needs to move frequently, under the guidance of the doctor, so that the final affected part can overlap with the scanning center as much as possible.

[0003] However, this adjustment or calibration process is very inefficient, requiring the doctor to visually inspect the detection center of the CT scanner bed and then instruct the patient to adjust the body position based on experience. On the one hand, this detection adjustment process is more dependent on the doctor's experience, and on the other hand, the efficiency of moving to the center is also very low, reducing the overall efficiency of the CT machine detection. Summary of the invention

[0004] An embodiment of the present invention provides a laser calibration and positioning device for a CT machine in the medical industry. To address the above-mentioned problem, a new calibration method is adopted to provide doctors with an intuitive central area reference, thereby improving the efficiency of position calibration.

[0005] The laser calibration and positioning device for a CT machine in the medical industry provided in an embodiment of the present invention comprises: a first laser lamp, a second laser lamp, a third laser lamp, a first mounting frame, a second mounting frame, a third mounting frame, a calibration frame, a laser detector and a controller;

[0006] The first mounting frame, the second mounting frame, and the third mounting frame are respectively arranged on the CT machine;

[0007] The first laser light is arranged on the first mounting frame, the second laser light is arranged on the second mounting frame, and the third laser light is arranged on the third mounting frame;

[0008] The calibration frame is arranged on the CT machine to be calibrated, and a first calibration gap, a second calibration gap and a third calibration gap are arranged on the calibration frame, and the first calibration gap, the second calibration gap and the third calibration gap correspond to the positions of the first laser light, the second laser light and the third laser light respectively;

[0009] The controller is electrically connected to the first laser light, the second laser light, the third laser light, and the laser detector respectively. The laser detector is used to be placed in the calibration frame to detect laser.

[0010] By adopting this technical solution, on the one hand, the center position of the CT machine and the position of the laser light can be corrected to calibrate the subsequent position detection; on the other hand, it can also intuitively indicate the detection center area of ​​the CT machine to the doctor, facilitate the operation of the CT machine, and improve the efficiency of CT detection.

[0011] In an optional solution, the first laser light and the second laser light are arranged horizontally.

[0012] This technical solution is to provide a horizontal reference for doctors by setting a first laser light and a second laser light, so as to facilitate calibration of the position of the CT machine and check whether the patient's position meets the horizontal requirements.

[0013] In an optional solution, the third laser light is arranged vertically.

[0014] This technical solution is to set up a third laser light to provide a vertical reference for doctors, so as to facilitate the calibration of the position of the CT machine and check whether the patient's position meets the vertical requirements.

[0015] In an optional solution, the first laser light and the second laser light are “inline” laser lights.

[0016] This technical solution is adopted in order to utilize the "inline" laser tube emitted by the "inline" laser lamp to detect whether the CT machine and the patient's body position meet the horizontal requirements. It has the advantages of simple structure, reliability and low cost.

[0017] In an optional solution, the third laser light is a "cross-shaped" laser light.

[0018] By adopting this technical solution, vertical detection can be achieved by setting up a "cross-shaped" laser light, and a reference of the detection area can be provided to facilitate the doctor's observation.

[0019] In an optional solution, the laser detector is in the shape of a flashlight, and a cylindrical laser detection plate is provided on the outer periphery of the laser detector.

[0020] This technical solution is adopted to provide a method for detecting and calibrating the vertical position and horizontal position of a CT machine on the scanning bed of the CT machine, which is convenient for users to use.

[0021] In an optional solution, the first mounting bracket, the second mounting bracket, and the third mounting bracket are respectively arranged on the CT machine at an angle of 60°.

[0022] The use of this technical solution can make the horizontal and vertical position detection results of the CT machine more accurate, and can perform a more comprehensive detection of the patient's position. Compared with the vertical-horizontal position detection, the detection range is larger and the results are more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0030] Figure 1 Schematic diagram of the overall structure of a laser calibration and positioning device for a CT machine in the medical industry according to an embodiment of the present invention.

[0031] like Figure 1 As shown, the laser calibration and positioning device for a CT machine in the medical industry provided by an embodiment of the present invention includes: a first laser light 1, a second laser light 2, a third laser light 3, a first mounting bracket 4, a second mounting bracket 5, a third mounting bracket 6, a calibration frame 7, a laser detector and a controller.

[0032] The first mounting frame 4, the second mounting frame 5, and the third mounting frame 6 are respectively arranged on the CT machine.

[0033] The first laser lamp 1 is arranged on a first mounting frame 4 , the second laser lamp 2 is arranged on a second mounting frame 5 , and the third laser lamp 3 is arranged on a third mounting frame 6 .

[0034] It should be noted that, in order to achieve different purposes, the installation positions of the first mounting bracket 4 , the second mounting bracket 5 , and the third mounting bracket 6 and the types of the first laser lamp 1 , the second laser lamp 2 , and the third laser lamp 3 are different.

[0035] The calibration frame 7 is arranged on the CT machine to be calibrated, and is provided with a first calibration gap 701, a second calibration gap 702 and a third calibration gap 703, and the first calibration gap 701, the second calibration gap 702 and the third calibration gap 703 correspond to the positions of the first laser light 1, the second laser light 2 and the third laser light 3 respectively.

[0036] It should be noted that the shape of the first calibration gap 701 is similar to the shape of the laser emitted by the first laser lamp 1 , the shape of the second calibration gap 702 is similar to the shape of the laser emitted by the second laser lamp 2 , and the shape of the third calibration gap 703 is similar to the shape of the laser emitted by the third laser lamp 3 .

[0037] The controller is electrically connected to the first laser light 1 , the second laser light 2 , the third laser light 3 , and the laser detector respectively. The laser detector is placed in the calibration frame 7 to detect the laser.

[0038] The working principle of the laser calibration and positioning device applied to the CT machine in the medical industry is as follows: the calibration frame 7 is fixed on the CT machine as a reference; if the light emitted by the first laser lamp 1 can just pass through the first calibration gap 701, then the position of the first laser lamp 1 is qualified, and the second laser lamp 2 and the third laser lamp 3 have the same function and judgment standard as the corresponding second calibration gap 702 and the third calibration gap 703; when the positions of the first laser lamp 1, the second laser lamp 2 and the third laser lamp 3 are determined, the lasers emitted by the three laser lamps are used to indicate the area of ​​the CT machine detection center, and at the same time provide a feedback light source for judging the patient's body position, and provide the patient's body location according to the feedback light source, so that the doctor can judge whether the user's body is in a suitable position, without direct observation on the spot or through the window, etc., and can be detected at a long distance. It should be noted that the feedback light irradiated by the laser on the human body can be collected by an existing camera or optical sensor, etc., so that the doctor can make an intuitive judgment or the system can accurately detect the patient's body position.

[0039] By adopting this technical solution, on the one hand, the center position of the CT machine and the position of the laser light can be corrected to calibrate the subsequent position detection; on the other hand, it can also intuitively indicate the detection center area of ​​the CT machine to the doctor, facilitate the operation of the CT machine, and improve the efficiency of CT detection.

[0040] In an optional solution, the first laser light 1 and the second laser light 2 are arranged horizontally.

[0041] This technical solution provides a horizontal reference for doctors by setting a first laser light 1 and a second laser light 2, so as to facilitate calibration of the position of the CT machine and check whether the patient's position meets the horizontal requirements.

[0042] In an optional solution, the third laser lamp 3 is arranged vertically.

[0043] This technical solution is adopted to provide a vertical reference for the doctor by setting the third laser light 3, so as to facilitate the calibration of the position of the CT machine and check whether the patient's position meets the requirements of the vertical direction.

[0044] In an optional solution, the first laser light 1 and the second laser light 2 are “inline” laser lights.

[0045] This technical solution is adopted in order to utilize the "inline" laser tube emitted by the "inline" laser lamp to detect whether the CT machine and the patient's body position meet the horizontal requirements. It has the advantages of simple structure, reliability and low cost.

[0046] In an optional solution, the third laser light 3 is a “cross-shaped” laser light.

[0047] By adopting this technical solution, vertical detection can be achieved by setting up a "cross-shaped" laser light, and a reference of the detection area can be provided to facilitate the doctor's observation.

[0048] In an optional solution, the laser detector is in the shape of a flashlight, and a cylindrical laser detection plate is provided on the outer periphery of the laser detector. It should be noted that setting the laser detection plate in a cylindrical shape belongs to the prior art.

[0049] This technical solution is adopted to provide a method for detecting and calibrating the vertical position and horizontal position of a CT machine on the scanning bed of the CT machine, which is convenient for users to use.

[0050] In an optional solution, the first mounting frame 4, the second mounting frame 5, and the third mounting frame 6 are respectively arranged on the CT machine at an angle of 60 degrees.

[0051] The use of this technical solution can make the horizontal and vertical position detection results of the CT machine more accurate, and can perform a more comprehensive detection of the patient's position. Compared with the vertical-horizontal position detection, the detection range is larger and the results are more accurate.

[0052] In the present invention, unless otherwise clearly specified and limited, a first feature being “on” or “under” a second feature may mean that the first feature and the second feature are in direct contact, or the first feature and the second feature are in indirect contact via an intermediate medium.

[0053] Moreover, the first feature being “above”, “above”, and “above” the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being “below”, “below”, and “below” the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
