DETAILED DESCRIPTION

[0016] In order to more clearly understand the above aspects, features and advantages of the embodiments, the embodiments will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth in order to provide a thorough understanding of the embodiments, but the embodiments can also be practiced without the other ways different from those described herein, therefore, the scope of protection of the embodiments is not limited by the specific embodiments disclosed below.

[0018] It is to be understood that the existing G-type arm equipment is usually equipped with only a single type of flat panel detector to acquire images, and the single type of flat panel detector cannot meet the image requirements of different parts and different sizes. The larger the size of the flat panel detector, the lower the image frame rate. The traditional G-type arm usually uses a small flat panel detector with a high frame rate, which cannot meet the requirements of high frame rate and large field of view at the same time. In some surgeries, it may be necessary to acquire a large area of images, for example, in a spine surgery, the doctor needs a full spine image. The traditional G-type arm needs to expose multiple times and then perform image stitching before displaying, which not only consumes a long time, but also increases the radiation damage by multiple exposures. Therefore, it has great practical application value to design a G-type arm with a large field of view and a high frame rate.

[0019] To overcome the above problems, the present application can provide a wide range of static X-ray images. At the same time, it also takes into account the display of dynamic X-ray images with high frame rate, providing more accurate diagnostic basis for doctors, solving the limitations of existing G-type arm equipment in image acquisition, and being able to meet the requirements of large area and high frame rate image acquisition at the same time. It is reasonable in design, easy to operate, and can improve the efficiency and accuracy of medical work.

[0020] Exemplarily, as shown in FIG. 1, the imaging device 1 provided by the present application includes a base 10, an arc-shaped connecting arm 11, a first ray source 122, a second ray source 124, a first detector 132, a second detector 134 and an industrial computer. The arc-shaped connecting arm 11 is arranged on the base 10. The first ray source 122 is arranged on the arc-shaped connecting arm 11 and can emit a first ray in a first direction. The second ray source 124 is arranged on the arc-shaped connecting arm 11 and can emit a second ray in a second direction. The first detector 132 is arranged on the arc-shaped connecting arm 11 and located in the first direction of the first ray source 122, and can receive the first ray transmitted through the measured object and generate a first identifiable signal. The second detector 134 is arranged on the arc-shaped connecting arm 11 and located in the second direction of the second ray source 124, and can receive the second ray transmitted through the measured object and generate a second identifiable signal. The industrial computer is arranged on the base 10 and connected with the first detector 132 and the second detector 134, and is used for acquiring and analyzing the first identifiable signal and the second identifiable signal and generating an image. Wherein, the detection area of the first detector 132 is larger than that of the second detector 134, and the frame rate of the first detector 132 is smaller than that of the second detector 134.

[0021] The imaging device 1 provided by the present application can meet the requirements of high frame rate and large field of view at the same time because there are two detectors with different frame rates and detection areas. Larger area images can be acquired through the first detector 132, and better frame rate can be ensured through the second detector 134. Compared with a single type of detector, image stitching is not required in the later stage, and the video production efficiency is improved.

[0022] In some embodiments, exemplarily, the first detector 132 and the second detector 134 are both wireless flat panel detectors. The first detector 132 can be selected from a high frame rate dynamic flat panel detector with a size of 9 inches x 9 inches or 12 inches x 12 inches, and the second detector 134 can be selected from a large field of view flat panel detector with a size of 12 inches x 24 inches or 12 inches x 48 inches.

[0023] In some embodiments, exemplarily, the arc-shaped connecting arm 11 is made of high-strength materials such as aluminum alloy, stainless steel, or titanium alloy. Aluminum alloy has high strength and light weight, so it is often used to manufacture structural components of the arc-shaped connecting arm 11. The excellent performance of aluminum alloy enables the arc-shaped connecting arm 11 to have sufficient carrying capacity and stability. Stainless steel has good corrosion resistance and mechanical properties, and is often used to manufacture critical components of the arc-shaped connecting arm 11, such as joints and connection points. The high strength and oxidation resistance of stainless steel ensure that the arc-shaped connecting arm 11 is not easily corroded and damaged during long-term use. Titanium alloy has excellent strength and corrosion resistance, and is suitable for manufacturing lightweight components of the arc-shaped connecting arm 11, such as supports and joints. The high strength and low density of titanium alloy make the arc-shaped connecting arm 11 have better maneuverability and flexibility.

[0024] In some embodiments, exemplarily, the first radiation source 122 and the first detector 132 are arranged on the arc-shaped connecting arm 11 in the up-down direction, and the first radiation source 122 is arranged at the highest point of the arc-shaped connecting arm 11. The second radiation source 124 and the second detector 134 are arranged on the arc-shaped connecting arm 11 in the left-right direction. That is, the first direction is the vertical direction, and the second direction is the horizontal direction.

[0025] In some embodiments, exemplarily, the first radiation source 122 and the second radiation source 124 are both X-ray sources and can both emit X-rays.

[0026] In some embodiments, exemplarily, as shown in FIG. 1, the imaging device 1 further comprises a first telescopic device 152 arranged on the arc-shaped connecting arm 11 and connected with the first radiation source 122, which can drive the first radiation source 122 to move in the first direction so as to make the first radiation source 122 approach or move away from the first detector 132. The imaging device 1 further comprises a second telescopic device 154 connected with the second detector 134, which drives the second detector 134 to move in the second direction so as to make the second detector 134 approach or move away from the second radiation source 124.

[0027] Of course, the second telescopic device 154 can also be connected with the second radiation source 124, which can drive the second radiation source 124 to move in the second direction so as to make the second radiation source 124 approach or move away from the second detector 134.

[0028] In this embodiment, the first telescopic device 152 can drive the first ray source 122 to be close to or away from the first detector 132, so as to adjust the distance between the first detector 132 and the first ray source 122, and the second telescopic device 154 can drive the second ray source 124 to be close to or away from the second detector 134, so as to adjust the distance between the second detector 134 and the second ray source 124, so as to realize different imaging effects and meet different imaging requirements.

[0029] In some embodiments, the imaging device 1 further includes a turnover device connected with the arc-shaped connecting arm 11, and the turnover device can rotate along the first rotation shaft 171, and when the turnover device rotates along the first rotation shaft 171, the arc-shaped connecting arm 11 can be turned over.

[0032] In this embodiment, the second arc-shaped arm 114 can move on the first arc line 115 relative to the first arc-shaped arm 112, so that the second arc-shaped arm 114 can be hidden or extended, and the size of the avoiding gap 14 can be adjusted, so that the patient can easily enter the operating bed from the avoiding gap 14. The first arc line 115 is an arc line where the arc-shaped connecting arm 11 is located. In addition, the first detector 132 is arranged on the first arc-shaped arm 112, and the second detector 134 is arranged on the second arc-shaped arm 114, which is mainly because the detection area of the second detector 134 is small, so that the distance of the avoiding gap 14 can be increased, and the patient can more easily enter the operating bed from the avoiding gap 14.

[0033] In some embodiments, the end of the second arc-shaped arm 114 connected with the first arc-shaped arm 112 is provided with a sliding part 1142, the end of the first arc-shaped arm 112 connected with the second arc-shaped arm 114 is provided with a sliding groove 1122, and the sliding part 1142 of the second arc-shaped arm 114 can slide in the sliding groove 1122 of the first arc-shaped arm 112, so as to complete the sliding of the second arc-shaped arm 114 on the first arc line 115.

[0034] In some embodiments, the imaging device 1 further comprises a locking device 16 arranged on the first arc-shaped arm 112 and / or the second arc-shaped arm 114, which is used to lock the position of the second arc-shaped arm 114 on the first arc-shaped arm 112 when the second arc-shaped arm 114 moves on the first arc 115.

[0035] In this embodiment, the second arc-shaped arm 114 can be locked by arranging the locking device 16, so as to fix the second detector 134 on the second arc-shaped arm 114. For example, the locking device 16 can lock the position of the sliding part 1142 of the second arc-shaped arm 114 in the sliding groove 1122 of the first arc-shaped arm 112.

[0036] In some embodiments, the imaging device 1 further comprises a rotating assembly connected with the arc-shaped connecting arm 11, which is used to drive the arc-shaped connecting arm 11 to rotate on the first arc 115.

[0037] In this embodiment, the imaging device 1 further comprises a rotating assembly connected with the arc-shaped connecting arm 11, which is used to drive the arc-shaped connecting arm 11 to rotate on the first arc 115, so as to adjust the incident angle of X-rays and complete multi-directional analysis.

[0038] It should be understood that the rotating assembly and the overturning device in the present application are the same device, which is the overturning and rotating device 17 shown in FIG. 1. The overturning and rotating device 17 can rotate around the first rotating shaft 171 thereof, so as to control the arc-shaped connecting arm 11 to overturn by 180°, or control the arc-shaped connecting arm 11 to rotate, for example, rotate clockwise by 90° or rotate counterclockwise by 42°.

[0039] In some embodiments, as shown in FIGS. 1, 3 and 4, the rotating assembly comprises a connecting box 172, a sliding rotating motor 174, a first connecting rope 176 and a second connecting rope 178. The connecting box 172 is sleeved on the outer side of the arc-shaped connecting arm 11 and is in sliding connection with the arc-shaped connecting arm 11. The sliding rotating motor 174 is arranged in the connecting box 172. One end of the first connecting rope 176 passes through the connecting box 172 and is connected with a first connecting point 1792 on the arc-shaped connecting arm 11, and the other end is connected with the sliding rotating motor 174. One end of the second connecting rope 178 passes through the connecting box 172 and is connected with a second connecting point 1794 on the arc-shaped connecting arm 11, and the other end is connected with the sliding rotating motor 174. The first connecting point 1792 and the second connecting point 1794 are located on the two sides of the sliding rotating motor 174. The sliding rotating motor 174 can tighten the first connecting rope 176 and expand the second connecting rope 178, so as to drive the arc-shaped connecting arm 11 to rotate in a third direction. The sliding rotating motor 174 can also tighten the second connecting rope 178 and expand the first connecting rope 176, so as to drive the arc-shaped connecting arm 11 to rotate in a fourth direction.

[0041] In this embodiment, the rotating assembly can drive the arc-shaped connecting arm 11 to rotate, so as to adjust the incident angles of the first ray and the second ray, thereby completing multi-directional analysis.
