Description

Technical Field

[0001] The present application relates to the technical field of scientific instruments, and in particular to a micro CT device. Background Art

[0002] Micro-CT is a non-destructive 3D imaging technology that uses radioisotopes as a radiation source to provide direct X-ray vision of objects. It also employs a large number of discretely arranged detector elements, forming an array detector, replacing traditional position-sensitive sensors. This array detects radiation intensity at each location and generates a corresponding dynamic digital signal, ultimately an image, in real time. This allows for a clear understanding of the internal microstructure of scanned objects without damaging them. Micro-CT is commonly used in scientific research, encompassing fields such as medicine, pharmacy, biology, archaeology, materials science, electronics, and geology. For example, in medicine and pharmacy, it provides high-resolution 3D images for studying the internal structure of bones and teeth, which is crucial for research into diseases such as osteoporosis, fractures, and osteoarthritis. In biology, micro-CT is used to study the internal structure and mechanical properties of biomaterials and to evaluate the suitability of biomimetic scaffolds for implantation. In electronics, micro-CT is used for jewelry authentication, and in geology, it helps analyze the internal structure of rocks and minerals. However, most existing Micro-CT devices are equipped with a yellow exposure lamp, which is turned off when not scanning and displays yellow light during scanning. The yellow exposure lamp has a single function, and if a single exposure lamp malfunctions, it may affect usage and safety, causing inconvenience to researchers. Utility Model Content

[0039] This application provides a micro CT device, such as Figures 1 to 3 As shown, the micro CT device includes: a body 100, multiple sets of light environment components, and a controller. The body 100 has a scanning cavity 110; the multiple sets of light environment components are all arranged on the body 100, and at least one set of light environment components extends around the circumference of the scanning cavity 110; the power supply lines of the multiple sets of light environment components are connected in parallel; and the light environment components are used to display different colors of light according to different working states of the body 100.

[0040] The aforementioned micro-CT device has multiple sets of light environment components installed on the body 100. Furthermore, at least one set of these light environment components is located circumferentially around the scanning cavity 110. The power supply lines for these multiple light environment components are connected in parallel. If one of these light environment components fails and cannot emit light, the remaining light environment components can still emit light normally, thereby improving the convenience of using the micro-CT device. The presence of at least one set of light environment components circumferentially around the scanning cavity 110 facilitates observation of the state near the scanning cavity 110 by the operator, and also adapts to the shape of the scanning cavity, resulting in a more aesthetically pleasing design and easier processing and manufacturing. Furthermore, the multiple light environment components can display different colors of light depending on the operating state of the body 100, making it easier for the operator to determine the operating state of the body 100 based on the color of the light environment components.

[0041] Specifically, the micro-CT device also includes a controller, and multiple groups of light environment components are electrically connected to the controller. Because multiple groups of light environment components are arranged in parallel, when one group of light environment components is damaged or fails, it does not affect the use of the micro-CT device. At this time, the controller can control the alarm to reduce the pressure on maintenance personnel.

[0042] In some embodiments, as Figure 1 and Figure 2 As shown, the present application is provided with multiple groups of light environment components, which include a first light environment component 201 , a second light environment component 202 and a third light environment component 203 .

[0043] In some embodiments, as Figure 1 and Figure 2As shown, the housing 100 includes a first end surface 120, a second end surface 130, and an outer peripheral surface 140 connecting the first and second end surfaces 120, 130. The first end surface 120 is provided with an opening that communicates with the scanning cavity 110. The first end surface 120 is provided with a set of first light environment components 201 extending circumferentially around the opening. The second end surface 130 is provided with a second light environment component 202. The first light environment components 201 are provided on each of the first end surfaces 120, extending circumferentially around the opening, thereby extending the first light environment components 201 provided on the first end surface 120 around the circumference of the scanning cavity 110. The second light environment component 202 is provided on the second end surface 130 to facilitate observation of the operating status of the housing 100 when a worker is located on the side of the housing 100 facing away from the scanning cavity 110.

[0044] Specifically, if Figure 1 As shown, at least one set of light environment components 200 is provided on the top surface of the body 100. The light environment components 200 provided on the top surface of the body 100, in conjunction with the first light environment component 201 and the second light environment component 202, increase the number of light environment components 200 provided on the body 100, thereby allowing staff to see at least one light environment component 200 at any location near the micro CT device.

[0045] More specifically, if Figure 1 As shown, the first end surface 120 and the second end surface 130 are connected by a cylindrical outer peripheral surface 140 , and the third light environment component 203 is arranged on the cylindrical outer peripheral surface 140 .

[0046] It should be noted that the first light environment component 201 is a group of light environment components extending circumferentially around the opening and arranged on the first end surface 120 among the multiple groups of light environment components; the second light environment component 202 is a group of light environment components arranged on the second end surface 130 among the multiple groups of light environment components; and the third light environment component 203 is a group of light environment components arranged on the top surface of the body 100 among the multiple groups of light environment components.

[0047] Furthermore, if Figures 1 to 3 As shown, the light environment component is in an arc shape. The light environment component is arranged in an arc shape so as to be compatible with the outer wall of the body 100, thereby providing surrounding light.

[0048] Furthermore, if Figures 1 to 3 As shown, the light environment assembly includes a light strip 210 and a light ring 220 connected to each other, and the light ring 220 is mounted on the body 100. The light environment assembly can be mounted on the body 100 by mounting the light strip 210 on the light ring 220 and then mounting the light ring 220 on the body 100.

[0049] Specifically, in some embodiments, the light ring 220 is connected to the body 100 by gluing; in some embodiments, the light ring 220 is connected to the body 100 by a snap-fit ​​structure; and in some embodiments, the light ring 220 is connected to the body 100 by a locking member. It is understood that there are various ways to connect the light ring 220 to the body 100, and the specific connection method is selected based on installation requirements.

[0050] Specifically, the light ring 220 is made of acrylic material.

[0051] Specifically, if Figures 1 to 3 As shown, the light ring 220 is provided with a limiting groove 221, and the light strip 210 is installed in the limiting groove 221. The limiting groove 221 is provided on the light ring 220, and the light strip 210 is arranged in the limiting groove 221, thereby limiting the relative position of the light strip 210 and the light ring 220.

[0052] More specifically, the light strip 210 can be connected to the wall of the limiting groove 221 in a variety of ways, such as adhesive connection, snap connection, and locking with a locking member. It is understood that the light strip 210 can be connected to the wall of the limiting groove 221 in a variety of ways, and the specific connection method is selected according to installation requirements.

[0053] Specifically, if Figures 1 to 3 As shown, the light environment component also includes a light diffuser 230, which is connected to the light ring 220 to seal the limit groove 221. The light-emitting surface of the light strip 210 faces the light diffuser 230. By setting the light diffuser 230 and connecting it to the light ring 220, the limit groove 221 is sealed, reducing the influx of external dust or water droplets into the limit groove 221 and protecting the light strip 210. The light-emitting surface of the light strip 210 faces the light diffuser 230, that is, the light emitted by the light strip 210 is emitted to the outside world through the light diffuser 230. In addition, the light diffuser 230 has a light-distributing effect, which improves the uniformity and brightness of the light source.

[0054] Specifically, if Figures 1 to 3 As shown, the light environment assembly also includes a light shield. The outer wall of the light ring 220 includes a first area and a second area. The first area is connected to the light diffuser 230, and the second area is connected to the light shield. The light shield is used to block light leakage from the second area. By providing the light shield and connecting the second area to the light shield, the light shield blocks light leakage from the second area, thereby reducing light leakage.

[0055] In one embodiment, the light shielding member is a tape. The tape is applied to the second area of ​​the light ring 220 to enhance the light shielding of the second area, reduce light leakage, and allow more light to be emitted through the light diffuser 230, thereby increasing the brightness of the light strip 210.

[0056] In one embodiment, the light shielding member is a light shielding coating. The light shielding coating is provided on the second area of ​​the light ring 220, for example, by spraying paint on the second area, so as to achieve a light shielding effect.

[0057] It should be noted that the outer wall of the light ring 220 includes a first area and a second area. The first area is used to install the light diffuser 230, and the second area is used to install the light shield. In other words, except for the surface on the outer wall of the light ring 220 where the light diffuser 230 is installed, all other surfaces are the second area and require the installation of the light shield.

[0058] Furthermore, the multiple light environment components are all connected to the controller, which can not only provide power to the multiple light environment components, but also control the light environment components to change color and brightness.

[0059] Specifically, the light environment component is configured to display different colors of light depending on the operating state of the machine body 100. A controller controls the light environment component to display different colors depending on the operating state. The micro CT device has a power-on state and a scanning and payoff state. When in the power-on state, the light environment component illuminates a first color. When in the scanning and payoff state, the light environment component illuminates a second color, where the first and second colors are different.

[0060] For example, when the micro-CT device is powered on, the controller controls multiple light environment components to illuminate simultaneously, with white light (the first color) at its brightest, reminding staff that the micro-CT device is powered on. When the micro-CT device is in the scanning and payout state, the controller controls multiple light environment components to illuminate simultaneously, with red light (the second color) at its brightest, reminding staff that the micro-CT device is scanning and testing.

[0061] Specifically, the light environment components are used to increase the brightness of the light when the radiation intensity increases during the scanning of the body 100. When the micro-CT device begins scanning an animal, the multiple light environment components change color to red. The brightness of the red light changes accordingly to the radiation intensity corresponding to the scanning power, reaching its highest brightness when the radiation intensity is highest. This allows workers to quickly determine the device status from a distance based on the color of the light environment, preventing them from approaching the device during scanning and causing misoperation.

[0062] Specifically, the micro-CT device also has a sleep state. When in the sleep state, the controller controls the brightness of the light environment components to decrease. The sleep state has two situations: one is that the micro-CT device has not been operated after being powered on, or the operation has not been carried out for a long time after the operation is completed; the other is that the micro-CT device is in the scanning and release state for a long time. In the first situation, if the micro-CT device has not been operated for a period of time after being powered on, or the operation has not been carried out for a long time after the operation is completed, the controller controls the brightness of the white light of multiple groups of light environment components to decrease, thereby prompting the staff to enter the sleep state of the micro-CT device and save power. If there is a human operation, the light environment components immediately exit the sleep state. In the second situation, if the scanning time is too long, multiple light environment components can be set to enter the sleep state, reducing the brightness of the red light or flashing at a low brightness, thereby prompting the staff to enter the sleep state of the long-term scanning.

[0063] It should be noted that, in either of the above situations, the controller will control the brightness of multiple groups of light environment components to reduce energy consumption.

[0064] Specifically, the light environment component displays different brightness levels based on the subject's breathing or ECG rate. During experiments, this brightness level helps alert staff to the current breathing or ECG value, guiding them on proper placement of the breathing pad / electrodes and the dosage of anesthetics.

[0065] For example, during the preparation phase for a live respiratory or ECG-gated scan, the colors of the multi-group light environment component can be displayed at different brightness levels based on the respiratory / ECG frequency, guiding the experimenter in the placement of the respiratory pad / electrodes and the use of anesthetics. For example, during respiratory gating, the respiratory rate of the mouse (scanning subject) is divided into three levels. If the respiratory rate is ≤40bpm, it can be assumed that the respiratory pad is incorrectly positioned or the anesthetic dose is too high. In this case, the brightness of the multi-group light environment component is the lowest. If the respiratory rate is 40 ≤ ≤100bpm, it can be assumed that the respiratory pad is correctly positioned and the anesthetic dose is correct. At this time, the respiratory gating effect is the best, and the brightness of the multi-group light environment component is normal. If the respiratory rate is ≥100bpm, the mouse's respiratory rate has exceeded the device's respiratory gating range, and the experimenter needs to adjust the anesthetic dose to reduce the mouse's respiratory rate. The brightness of the multi-group light environment component is the highest.

[0066] The present application also provides a micro CT device, which includes: a body and at least one set of light environment components, the body having a scanning cavity; at least one set of light environment components is arranged on the body, and at least one set of light environment components is arranged around the scanning cavity; the light environment components are used to display different colors of light according to different working states of the body.

[0067] The aforementioned micro-CT device features at least one set of light ring mirrors surrounding the scanning chamber 110, facilitating observation of the surrounding area. The mirrors adapt to the shape of the scanning chamber, creating a more aesthetically pleasing aesthetic and making manufacturing easier. Furthermore, the light environment component displays different colors depending on the operating status of the device 100, allowing operators to easily determine the operating status of the device 100 based on the color of the light environment component.

[0068] In some implementations, the light environment component is also used to increase light brightness when the intensity of radiation increases during scanning of the body 100. When the micro-CT device begins scanning an animal, the brightness of the light environment component changes accordingly based on the radiation intensity corresponding to the scanning power. When the radiation intensity is at its highest, the light environment component is at its highest brightness. This allows personnel to quickly determine the device status from a distance based on the color of the light environment, preventing them from approaching the device during scanning and causing misoperation.

[0069] In some implementations, the light environment component is further configured to display different brightness levels based on the subject's respiration or ECG rate. During an experiment, this brightness level can be adjusted to remind personnel of the current respiration or ECG rate, guiding them in proper placement of the breathing pad / electrodes and the use of anesthetic dosage.

[0070] The present application also provides a control method of a micro CT device using any one of the above items, wherein the micro CT device has a power-on state and a scanning and release state;

[0071] When in a power-on state, controlling multiple light environment components to light up simultaneously, and multiple groups of light environment components are displayed in a first color;

[0072] When in the scanning and releasing state, the plurality of light environment components are controlled to display a second color, wherein the first color and the second color are different.

[0073] When the micro-CT device is powered on, i.e., in the powered-on state, multiple sets of light environment components are controlled to illuminate simultaneously, displaying a first color (e.g., white light) to alert personnel that the micro-CT device is powered on. When the micro-CT device is in the scanning and payout state, multiple sets of light environment components are controlled to illuminate simultaneously, displaying a second color (e.g., red light) to alert personnel that the micro-CT device is scanning and testing.

[0074] In some embodiments, when in the scanning and payoff mode, the brightness of the second color increases as the intensity of the radiation used to scan the body 100 increases. When the micro-CT device begins to payoff scan an animal, the color of the multiple light environment components changes to red. The brightness of the red light varies according to the radiation intensity corresponding to the scanning power, reaching its highest brightness when the radiation intensity is highest. This allows personnel to quickly determine the device status from a distance based on the color of the light environment, preventing them from approaching the device during scanning and potentially causing misoperation.

[0075] In some embodiments, the micro-CT device has a sleep state. When in the sleep state, the controller controls the brightness of the light environment component to be reduced. Specifically, the sleep state can occur in two situations: one is when the micro-CT device is powered on but no operation is performed, or when an operation is completed but no further operation is performed; the other is when the micro-CT device is in a scanning and payout state for an extended period of time.

[0076] In the first scenario, if no other operations are performed on the micro-CT device for a period of time after powering on, or if no further operations are performed after the operation is completed, the brightness of the white light of the multiple light environment components (including the first light environment component 201, the second light environment component 202, and the third light environment component 203) is controlled to decrease, thereby prompting the operator to enter a sleep state of the micro-CT device to save power. If a human operator operates the light environment component, the sleep state is immediately exited.

[0077] When in the second situation, multiple groups of light environment components (including the first light environment component 201, the second light environment component 202 and the third light environment component 203) are controlled to enter a sleep state, and the brightness of the red light is reduced or flashes at a low brightness, thereby prompting the staff to enter a sleep state for long-term scanning of the micro CT equipment, saving energy consumption.

[0078] In some embodiments, the light environment control component displays different brightness according to the respiration or ECG frequency of the scanned subject, thereby guiding the experimenter in the placement of the breathing pad / electrode and the use of anesthetic dosage.

[0079] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
