Description

Technical Field

[0001] This application relates to the field of medical device technology, such as a detector and a scanning device. Background Technology

[0002] To capture more slices with each rotation of the X-ray tube in a CT scanner, the number of detector rows needs to be increased to expand the detector's coverage width. As the number of detector rows increases, the number of electronic components, especially data processing chips, also needs to increase. Since most electronic components dissipate their power as heat, heat accumulates inside the detector; the more detector rows there are, the greater the heat generation. Without adequate heat dissipation, the internal temperature of the detector will rise.

[0003] In related technologies, air cooling is used to dissipate heat from the detector of a CT scanner. This is achieved by selecting an axial fan and placing it on the front beam of the CT detector, directly in front of the detector module assembly.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: As the number of detector rows increases, the airflow along the axial fan moves upwards, resulting in temperature differences between the various sub-modules of the detector. The more sub-modules there are, the greater the temperature difference becomes. These temperature variations between the detector sub-modules cause fluctuations in the raw CT image data, often accompanied by artifacts, affecting the accuracy of the scan results.

[0030] In some embodiments, combined with Figures 1 to 3As shown, a detector 100 is provided, including a housing 110 and a detector module 120. The housing 110 includes a mounting cavity 1102, a heat dissipation duct 1104, an air inlet 1106, and an air outlet 1108. A first end of the mounting cavity 1102 is connected to the air inlet 1106, and a second end opposite to the first end is connected to the air outlet 1108. The air inlet end of the heat dissipation duct 1104 is connected to the air inlet 1106, and the air outlet end of the heat dissipation duct 1104 is connected to the mounting cavity 1102. The detector module 120 is disposed within the mounting cavity 1102, located between the air inlet 1106 and the air outlet 1108. Airflow enters the heat dissipation duct 1104 and the mounting cavity 1102 through the air inlet 1106 and is then discharged through the air outlet 1108, serving to dissipate heat from the detector module 120 within the mounting cavity 1102.

[0031] The detector 100 provided in this disclosure has a housing 110 with a mounting cavity 1102 and a heat dissipation duct 1104, both of which are connected to an air inlet 1106 and an air outlet 1108. Furthermore, the air inlet end of the heat dissipation duct 1104 is connected to the air inlet 1106 of the housing 110, and the air outlet end of the heat dissipation duct 1104 is connected to the mounting cavity 1102. Thus, combined with… Figure 2 and Figure 3 As shown (arrows in the figure indicate airflow direction), two heat dissipation air paths are formed within the housing 110. One path involves airflow entering the mounting cavity 1102 through the air inlet 1106 and exiting through the air outlet 1108, carrying away heat from the detector module 120 within the mounting cavity 1102. The other path involves airflow entering the heat dissipation duct 1104 through the air inlet 1106, entering the mounting cavity 1102 through the heat dissipation duct 1104, and exiting through the air outlet 1108, thereby dissipating heat from the detector module 120 located between the air outlet of the heat dissipation duct 1104 and the air outlet 1108 of the housing 110. By using the detector 100 provided in this disclosure, the detector module 120 is cooled by two cooling air paths formed by the cooling air duct 1104 and the mounting cavity 1102, thereby improving the cooling efficiency and effect of the detector 100, reducing the temperature difference between the detector modules 120, and thus improving the data acquisition and conversion stability of the detector 100, reducing artifacts, and improving image quality.

[0032] Optionally, combined Figure 2 and Figure 3 As shown, the heat dissipation duct 1104 is arranged adjacent to the mounting cavity 1102.

[0033] In this embodiment, by arranging the heat dissipation duct 1104 adjacent to the mounting cavity 1102, the heat inside the mounting cavity 1102 can be dissipated through heat conduction.

[0034] Optionally, combined Figure 2 and Figure 3 As shown, the air outlet of the heat dissipation duct 1104 is located between the first and second ends of the mounting cavity 1102, and at a preset position. This preset position is set according to the heat dissipation requirements of the detector module. Specifically, the air outlet of the heat dissipation duct 1104 is located between the first and second ends of the mounting cavity 1102, and at a central position. Alternatively, the air outlet of the heat dissipation duct 1104 is located between the first and second ends of the mounting cavity 1102, and is closer to the second end of the mounting cavity 1102 than to the first end. That is, the preset position includes either a central position or a position closer to the second end of the mounting cavity 1102 than to the first end.

[0035] In this embodiment, the airflow that enters the mounting cavity 1102 directly from the air inlet 1106 dissipates heat from the detector module 120 located on one side of the air inlet 1106. As the airflow flows and cools the detector module 120, the airflow temperature increases, resulting in poor heat dissipation for the detector module 120 located far from the air inlet 1106.

[0036] This application positions the air outlet of the heat dissipation duct 1104 at a preset location within the mounting cavity 1102. For example, the preset location is the middle position. The airflow directly enters the middle and rear part of the mounting cavity 1102 through the heat dissipation duct 1104. Since it bypasses the front half of the detector module 120 and directly contacts the middle and rear part of the detector module 120, the middle and rear part of the detector module 120 comes into contact with more cool airflow. At the same time, the heat dissipation area is also increased, thereby improving the heat dissipation effect of the detector module 120 in the middle and rear part area. This achieves the purpose of reducing the temperature of the detector module 120 in the middle and rear part area and reducing the overall temperature difference of the detector module 120.

[0037] Optionally, combined Figure 4 , Figure 5 and Figure 6 As shown, the detector module 120 includes multiple module supports 121 and a detector chip 124. One end of the module support 121 extends adjacent to the first end of the mounting cavity 1102, and the other end extends adjacent to the second end of the mounting cavity 1102. A flow channel 122 is formed between adjacent module supports 121, with the two ends of the flow channel 122 corresponding to an air inlet 1106 and an air outlet 1108, respectively. The detector chip 124 is mounted on the module support 121; airflow enters the flow channel 122 through the air inlet 1106 and exits through the air outlet 1108, serving to dissipate heat from the detector chip 124.

[0038] In this embodiment, to meet the functional requirements of the detector module 120, the detector module includes multiple detector chips 124 and multiple module brackets 121 for mounting the multiple detector chips 124. There is a gap between adjacent module brackets 121, forming a flow channel 122. The two ends of the flow channel 122 are connected to an air inlet 1106 and an air outlet 1108, respectively. Thus, airflow enters the flow channel 122 through the air inlet 1106 and exits through the air outlet 1108, cooling the detector chips 124 as the airflow passes through the flow channel 122. It should be noted that the detector chip 124 is not an improvement of this application; therefore, its structure is not specifically described, but can be understood as the chip structure in the prior art used by the detector 100.

[0039] Optionally, combined Figure 3 , Figure 7 and Figure 8 As shown (the arrows in the figure indicate the airflow direction), the module bracket 121 includes an airflow duct 123. The inlet of the airflow duct 123 is correspondingly set to the air outlet of the heat dissipation duct 1104, and the outlet of the airflow duct 123 is correspondingly set to the air outlet 1108.

[0040] In this embodiment, an airflow duct 123 is formed in the middle and rear region of the module bracket 121. The inlet of the airflow duct 123 is connected to the outlet of the heat dissipation duct 1104, and the outlet of the airflow duct 123 is connected to the outlet 1108. Thus, external airflow enters the heat dissipation duct 1104 through the inlet 1106, enters the airflow duct 123 through the outlet of the heat dissipation duct 1104, and is discharged through the outlet of the airflow duct 123 and the outlet 1108. This enables heat dissipation and cooling of the middle and rear part of the detector module 120. The external airflow passes through the heat dissipation duct 1104, bypassing the front half of the detector module 120, and directly cools the rear half of the detector module 120, thereby reducing the temperature difference between the front and rear parts of the detector module 120.

[0041] Optionally, the flow duct 123 also extends through the module bracket 121 along its extension direction. The through-port of the flow duct 123 near the first end of the mounting cavity 1102 is connected to the air inlet 1106, and the through-port of the flow duct 123 near the second end of the mounting cavity 1102 constitutes the outlet of the flow duct 123. By providing the through-duct 123, external airflow enters the flow duct 123 and the flow channel 122 through the air inlet 1106, and is discharged through the air outlet 1108. In this way, dual heat dissipation and cooling of the entire detector module 120 can be achieved, thereby improving the cooling effect.

[0042] Optionally, combined Figure 5, Figure 6 and Figure 7 As shown, the detector module 120 also includes a heat sink 125, which is disposed on the module bracket 121 and located on both sides of the flow channel 122.

[0043] In this embodiment, heat sinks 125 are provided on the side walls of opposite sides of the module bracket 121. Airflow passing through the flow channel 122 can carry away the heat emitted by the heat sink 125 area, thereby reducing the temperature of the module bracket 121 and improving the heat dissipation effect on the detector module 120.

[0044] Optionally, combined Figure 2 As shown, the housing 110 includes a base 111 and a cover 112. The detector module 120 is disposed on the base 111. The cover 112 is disposed on the base 111, and the cover 112 and the base 111 enclose a mounting cavity 1102 and define a heat dissipation duct 1104.

[0045] In this embodiment, the base 111 of the housing 110 is used to support the detector module 120. The cover 112 is connected to the base 111, enclosing a mounting cavity 1102 for mounting the detector module 120. A heat dissipation duct 1104 is provided in the cover 112 to increase the heat dissipation duct 1104 for the detector module 120, thereby improving the heat dissipation effect of the detector module 120 and reducing the temperature difference between the front and rear parts of the detector module 120.

[0046] Optionally, combined Figure 2 As shown, the cover 112 includes: a cover body 113, an outer cover 114, and an end plate 115. The cover body 113 and the base 111 enclose a mounting cavity 1102. The outer cover 114 is disposed on the cover body 113, located outside the mounting cavity 1102, and the outer cover 114 and the cover body 113 enclose a heat dissipation duct 1104. The end plate 115 is connected to the outer cover 114 or the base 111 and is adjacent to the first end of the mounting cavity 1102; an air inlet 1106 is disposed on the end plate 115.

[0047] In this embodiment, the cover body 113 is used to enclose the mounting cavity 1102 with the base 111. The outer cover 114 is disposed on the outer periphery of the cover body 113, so that the outer cover 114 and the cover body 113 enclose a heat dissipation air duct 1104. The end plate 115 is used to be disposed at the end of the cover body 113 and the outer cover 114, and is used to provide an air inlet 1106, so that external airflow enters the mounting cavity 1102 and the heat dissipation air duct 1104 through the air inlet 1106.

[0048] Optionally, combined Figure 2 and Figure 3 As shown, the cover body 113 has an overflow hole 116, and the air outlet of the heat dissipation duct 1104 is connected to the mounting cavity 1102 through the overflow hole 116.

[0049] In this embodiment, by creating flow holes 116 on the cover body 113, the heat dissipation duct 1104 and the mounting cavity 1102 are connected through the flow holes 116, allowing airflow in the heat dissipation duct 1104 to enter the mounting cavity 1102 through the flow holes 116. Multiple flow holes 116 are arranged side-by-side. By providing multiple flow holes 116, the airflow rate is increased, thereby improving the heat dissipation effect.

[0050] Optionally, the cover 112 further includes a guide plate 117, which is disposed between the cover body 113 and the outer cover 114 and is located at one end of the heat dissipation air duct 1104 near the end plate. The guide plate 117 has a plurality of guide holes 118, which are connected to the air inlet 1106 on the end plate.

[0051] In this embodiment, a guide plate 117 is provided at the air inlet end of the heat dissipation duct 1104. External airflow enters the heat dissipation duct 1104 through the air inlet 1106 and the guide hole 118. By providing the guide hole 118, the guiding effect on the airflow entering the heat dissipation duct 1104 is improved.

[0052] Optionally, the 111 base includes: a frame 1110, a detector module 120 disposed in the frame 1110; an extension 1111 disposed on the frame edge of the frame 1110 adjacent to the second end of the mounting cavity 1102; and an air outlet 1108 disposed in the extension 1111, wherein the frame 1110, the cover 112, and the extension 1111 enclose the mounting cavity 1102.

[0053] In this embodiment, the 111 base includes a frame 1110 and an extension 1111. The extension 1111 is disposed on the frame edge of the frame 1110 and extends towards the cover. Thus, the end plate 115 is adjacent to the first end of the mounting cavity 1102, and the extension 1111 is adjacent to the second end of the mounting cavity 1102. The frame 1110 is used to support the detector module 120. An air outlet 1108 is disposed on the extension and includes multiple air outlet holes. Thus, external airflow enters through the air inlet 1106, passes through the mounting cavity 1102 and the heat dissipation duct 1104, and is discharged through the air outlet 1108, achieving dual heat dissipation for the detector module and improving the heat dissipation effect.

[0054] In some examples, combined Figure 1 , Figure 2 and Figure 3As shown, the direction from the air inlet 1106 to the air outlet 1108 is defined as the Z-direction, the thickness direction of the housing 110 is defined as the Y-direction, and the length direction of the housing 110 is defined as the X-direction. The X, Y, and Z directions are perpendicular to each other. The air inlet 1106 is located on the end plate 115 and includes multiple air inlets spaced apart along the X-direction. The air outlet 1108 is located on the base 111 on the side away from the air inlet 1106 along the Z-direction. The air outlet 1108 includes multiple air outlets spaced apart along the X-direction. Multiple module supports 121 are arranged sequentially along the X-direction, such that adjacent module supports 121 form a flow channel 122 extending along the Z-direction. To improve airflow, the outlets of the flow channel 122 can be matched one-to-one with the air outlets to improve airflow efficiency.

[0055] In some examples, combined Figure 2 and Figure 3 As shown, multiple flow holes 116 are arranged sequentially along the X direction. To improve airflow efficiency, the flow holes 116 are aligned one-to-one with the inlets of the flow ducts 123 on the module bracket 121, allowing airflow entering the heat dissipation duct 1104 to directly enter the flow duct 123 through the flow holes 116, thereby improving airflow efficiency and heat dissipation. Thus, the air inlet 1106, heat dissipation duct 1104, flow holes 116, flow duct 123, and air outlet 1108 form heat dissipation airflow path B. The air inlet 1106, flow channel 122, and air outlet 1108 form heat dissipation airflow path A. In heat dissipation airflow path A, the airflow temperature gradually increases from contact with the module bracket 121 until it reaches the air outlet 1108. In the heat dissipation airflow path B, because it bypasses the front half of the module bracket 121 and directly contacts the middle and rear parts of the module bracket 121, the middle and rear parts of the bracket are exposed to more cool air, and the heat dissipation area is also increased. This structure provides greater heat dissipation to the middle area of ​​the module bracket 121, thereby reducing the temperature of the middle and rear parts of the bracket. This reduces the temperature of the rear half of the module area and minimizes temperature differences.

[0056] Optionally, the mounting cavity 1102 corresponding to the flow hole 116 is located in the middle of the module bracket 121 along the Z-direction, so that the airflow from the flow hole 116 can dissipate heat for the rear half of the module bracket 121. It should be noted that the opening position of the flow hole 116 corresponds to the inlet of the flow duct 123 on the module bracket 121. The position is not limited to the middle position. It can be slightly closer to the center of the air outlet 1108 or slightly closer to the side of the air inlet 1106. The specific position can be set according to the specific heat dissipation requirements.

[0057] Optionally, combined Figure 1As shown, the detector 100 also includes a fan 130, which is disposed on the end plate 115 and is used to drive external airflow into the mounting cavity 1102 and the heat dissipation duct 1104.

[0058] In this embodiment, by providing a fan 130 on the end plate 115 and opposite to the air inlet 1106, the fan 130 drives external airflow into the mounting cavity 1102 and the heat dissipation duct 1104, thereby increasing the airflow rate and thus improving the heat dissipation effect and efficiency.

[0059] In some examples, combined Figure 1 As shown, multiple air inlets are provided at the end of the cover 112, and each air inlet is equipped with a fan 130, thereby improving the airflow driving effect and driving efficiency, and thus improving the heat dissipation effect.

[0060] In some examples, a first air inlet and a second air inlet are provided on the cover 112. The first air inlet is connected to the heat dissipation duct 1104, and the second air inlet is connected to the mounting cavity 1102. A fan 130 is respectively installed in the first and second air inlets. This arrangement of corresponding air inlets and fans 130 for the heat dissipation duct 1104 and mounting cavity 1102 allows for flexible heat dissipation control; the fans 130 can be started separately or simultaneously, improving both operational flexibility and heat dissipation efficiency.

[0061] In some embodiments, a scanning device is provided, including: a device body; and a detector 100 as described in any of the above embodiments, disposed on the device body.

[0062] The scanning device provided in this embodiment includes a device body and a detector 100 as described in any of the above embodiments. The housing 110 of the detector 100 is provided with a mounting cavity 1102 and a heat dissipation duct 1104, both connected to an air inlet 1106 and an air outlet 1108. Furthermore, the air inlet end of the heat dissipation duct 1104 is connected to the air inlet 1106 of the housing 110, and the air outlet end of the heat dissipation duct 1104 is connected to the mounting cavity 1102. Thus, two heat dissipation air paths are formed within the housing 110. One path involves airflow entering the mounting cavity 1102 through the air inlet 1106, carrying away heat from the detector module 120 within the mounting cavity 1102, and dissipating it through the air outlet 1108. Another path involves airflow entering the heat dissipation duct 1104 through the air inlet 1106, and then entering the mounting cavity 1102 through the heat dissipation duct 1104. The heat from the detector module 120, located between the air outlet of the heat dissipation duct 1104 and the air outlet 1108 of the housing 110, is discharged through the air outlet 1108. By employing the detector 100 provided in this disclosure, the detector module 120 is cooled by two separate airflow paths formed by the heat dissipation duct 1104 and the mounting cavity 1102. This improves the heat dissipation efficiency and effect of the detector 100, reduces the temperature difference between the detector modules 120, and thus enhances the stability of data acquisition and conversion, reduces artifacts, and improves image quality.

[0063] Optionally, the scanning device can be either a CT scanning device or a PET scanning device. The PET scanning device is either a positron emission tomography (PET) or a PETCT, which integrates PET and CT.
