Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a detection device and a multimodal medical imaging system. Background Art

[0002] With the development of science and technology, people's demands for healthy living are getting higher and higher. Breast disease is a major factor affecting women's health. Therefore, how to accurately diagnose breast disease is a new challenge facing medical staff.

[0003] Currently, breast disease examinations and early screening for breast cancer are primarily performed through breast X-ray imaging or breast ultrasound imaging. The principle of breast X-ray imaging is similar to the exposure principle of other X-ray devices. It primarily utilizes the penetrating properties of X-rays and the differences in the response of different tissues to X-rays as they penetrate human tissue. Finally, through the accumulation of different energies, different breast images (including two-dimensional and three-dimensional tomographic imaging) are formed on the image with varying grayscales. Three-dimensional tomographic imaging involves rotating the X-ray tube to obtain projection data at different angles and reconstruct the final tomographic image. Breast ultrasound imaging, on the other hand, uses an ultrasonic beam to scan the human body and, by receiving and processing the reflected signals, obtain images of internal organs. Three-dimensional ultrasound imaging reconstructs the two-dimensional ultrasound image of the breast into a three-dimensional image, thereby obtaining images in the coronal, sagittal, and transverse planes.

[0004] The main advantage of X-ray imaging is its ability to identify details such as tiny calcifications, enabling early detection of potential breast lesions. However, its disadvantages are that it requires significant breast compression and makes it difficult to visualize the complete structure of lesions. Ultrasound imaging can clearly visualize the complete structure of lesions, but it struggles to detect details such as tiny calcifications. Therefore, combining the advantages of X-ray and ultrasound imaging is a pressing issue. Summary of the Invention

[0005] Based on this, it is necessary to provide a detection device and a multimodal medical imaging system to address the above problems.

[0006] A detection device includes a cover and an X-ray detector accommodated in the cover, wherein the detection surface of the X-ray detector is arranged opposite to the cover; the detection device also includes an ultrasonic detector accommodated in the cover; the ultrasonic detector and the X-ray detector are capable of relative movement; and the ultrasonic detector is capable of moving outside the detection surface of the X-ray detector.

[0007] In one embodiment, the detection surface of the X-ray detector is arranged opposite to the inner side surface of the cover; the ultrasound detector is movably arranged in the cover, and the ultrasound detector can also move and fit into the inner side surface of the cover.

[0008] In one embodiment, the ultrasonic detector is movably disposed in the interior of the housing along a horizontal direction; and the X-ray detector is movably disposed in the housing along a vertical direction.

[0010] In one embodiment, the ultrasonic couplant is a solid couplant.

[0011] In one embodiment, the detection device further includes a scraping device, which is slidably disposed on the inner side surface of the cover shell, and is used to scrape the ultrasonic coupling agent remaining on the inner side surface.

[0012] In one embodiment, the detection device further includes a storage device, which is disposed on one side of the cover shell and is used to store the ultrasonic coupling agent scraped by the scraping device.

[0013] In one embodiment, the detection device further includes a first slide rail arranged in a horizontal direction, the first slide rail is arranged on the cover, the first slide rail is arranged between the end of the cover and the X-ray detector, and the ultrasonic detector is slidably arranged on the first slide rail.

[0014] In one embodiment, the detection device further includes a second slide rail disposed on the cover along a vertical direction, and the X-ray detector is slidably disposed on the second slide rail.

[0015] In one embodiment, the detection device is used in a mammography machine.

[0016] A multimodal medical imaging system, comprising:

[0017] base; and

[0018] The detection device is arranged on the base.

[0019] In one embodiment, the multimodal medical imaging system is a mammography machine.

[0020] The detection device provided in an embodiment of the present application includes a housing and an X-ray detector housed within the housing. The detection surface of the X-ray detector is disposed opposite the housing. Therefore, the detection surface of the X-ray detector can receive X-rays incident from the housing. The detection device also includes an ultrasonic detector housed within the housing. The ultrasonic detector and the X-ray detector are capable of relative movement. The ultrasonic detector can be moved beyond the detection surface of the X-ray detector. When X-ray detection of the tissue to be detected is required, the ultrasonic detector can be moved beyond the detection surface of the X-ray detector, away from the tissue to be detected and the X-ray detector. In other words, the ultrasonic detector does not block the X-ray detector from receiving X-rays. In this case, the ultrasonic detector does not affect the operation of the X-ray detector. When ultrasonic detection of the tissue to be detected is required, the ultrasonic detector can be moved to a suitable position to detect the tissue to be detected. Since the X-ray detector is not required at this time, the ultrasonic detector can block the detection surface of the X-ray detector and emit ultrasonic waves to detect the tissue to be detected. Therefore, the detection device can select an X-ray detector or an ultrasonic detector to work according to needs, so as to give full play to the advantages of the X-ray detector and the ultrasonic detector, and has the advantage of being flexible and convenient to use.

[0033] See Figure 1 , Figure 1 An embodiment of the present application provides a detection device 10. The detection device 10 includes a housing 100 and an X-ray detector 210 housed within the housing 100. The detection surface of the X-ray detector 210 is disposed opposite the housing 100. The detection device 10 also includes an ultrasonic detector 300 housed within the housing 100. The ultrasonic detector 300 is capable of relative movement with the X-ray detector 210. The ultrasonic detector 300 is capable of moving beyond the detection surface of the X-ray detector 210.

[0034] The housing 100 encloses a storage space 110. The X-ray detector 210 and the ultrasonic detector 300 are both disposed in the storage space 110. The shape of the housing 100 is not limited, as long as it can form a space for accommodating the X-ray detector 210 and the ultrasonic detector 300. The shape of the housing 100 can be determined based on the positions of the X-ray detector 210 and the ultrasonic detector 300 within the housing 100. The housing 100 can be made of an alloy or a polyester material.

[0035] The X-ray detector 210 can be a device that converts X-ray energy into a recordable electrical signal. The X-ray detector 210 can receive radiation exposure and then generate an electrical signal proportional to the radiation intensity. The strength of the signal received by the X-ray detector 210 can depend on the density of the tissue within the cross-section of the tissue to be detected 540. For example, bone has a higher density and absorbs more X-rays, so the signal received by the X-ray detector 210 is weaker; lower-density tissue, such as fat, absorbs less X-rays, so the signal received by the X-ray detector 210 is stronger. Therefore, the strength of the signal received by the X-ray detector 210 can reflect the state of human tissue. The ultrasound detector 300 can scan the human body with an ultrasonic beam and obtain images of internal organs by receiving and processing the reflected signals.

[0036] The X-ray detector 210 may be a flat-panel detector. The detection surface of the X-ray detector 210 may be the area within the flat-panel detector that can perform detection functions. Structurally, the detection surface may be the area of ​​the flat-panel detector, excluding the frame, where the electronic components of the flat-panel detector with photoelectric conversion functions are located.

[0037] The detection surface of the X-ray detector 210 is disposed opposite to the housing 100, so that the detection surface of the X-ray detector 210 can receive X-rays through the housing 100. The detection surface of the X-ray detector 210 can be disposed opposite to the top surface of the housing 100. The tissue to be detected 540 can be placed on one side of the top surface of the housing 100.

[0038] The ultrasound detector 300 and the X-ray detector 210 are capable of relative movement. That is, one of the ultrasound detector 300 and the X-ray detector 210 can be fixed relative to the housing 100, while the other can be movably disposed relative to the housing 100. Alternatively, both the ultrasound detector 300 and the X-ray detector 210 can be movably disposed relative to the housing 100.

[0039] It is understood that the ultrasonic detector 300 and the X-ray detector 210 can both be connected to the inner wall of the housing 100, and their positions can be adjusted by adjusting their movements relative to the housing 100. The connection between the ultrasonic detector 300 and the X-ray detector 210 and the inner wall of the housing 100 is not limited to any form, as long as they can achieve relative fixation and movement.

[0040] An independent motion mechanism may also be provided in the housing 100. This motion mechanism is connected to both the ultrasound detector 300 and the X-ray detector 210 to control the independent or simultaneous movement of the ultrasound detector 300 and the X-ray detector 210. The motion mechanism may be a manipulator, a three-axis motion device, or other device to directly adjust the relative positions of the two.

[0041] It can be understood that the movement forms of the ultrasonic detector 300 and the X-ray detector 210 can adopt existing technologies. The present application does not limit the type of specific movement structure, as long as the two can achieve a specific range of movement.

[0042] The ultrasonic detector 300 can be moved outside the detection surface of the X-ray detector 210, that is, the projection of the ultrasonic detector 300 on the plane where the detection surface is located does not overlap with the detection surface. The ultrasonic detector 300 will not block the X-ray detector 210 from receiving X-rays.

[0043] The detection device 10 provided in an embodiment of the present application includes a housing 100 and an X-ray detector 210 housed within the housing 100. The detection surface of the X-ray detector 210 is disposed opposite the housing 100. Therefore, the detection surface of the X-ray detector 210 can receive X-rays incident from the housing 100. The detection device 10 also includes an ultrasonic detector 300 housed within the housing 100. The ultrasonic detector 300 is capable of relative movement with the X-ray detector 210. The ultrasonic detector 300 can move outside the detection surface of the X-ray detector 210.

[0044] When X-ray detection of the tissue 540 is required, the ultrasound probe 300 can be moved outside the detection surface of the X-ray detector 210, away from both the tissue 540 and the X-ray detector 210. This means that the ultrasound probe 300 will not block the X-ray detector 210 from receiving X-rays. In this case, the ultrasound probe 300 will not affect the operation of the X-ray detector 210. When ultrasound detection of the tissue 540 is required, the ultrasound probe 300 can be moved to a suitable position to detect the tissue 540. Since the X-ray detector 210 is not required at this time, the ultrasound probe 300 can block the detection surface of the X-ray detector 210 and transmit ultrasound waves to detect the tissue 540. The detection device 10 can select either the X-ray detector 210 or the ultrasound detector 300 for operation as needed, fully leveraging the advantages of both the X-ray detector 210 and the ultrasound detector 300, offering the advantages of flexibility and convenience.

[0045] In one embodiment, the detection surface of the X-ray detector 210 is disposed opposite the inner side surface 120 of the housing 100. The inner side surface 120 refers to the inner wall surface of the housing 100 opposite the detection surface. The ultrasonic detector 300 is movably disposed in the housing 100. The ultrasonic detector 300 is also movable and adheres to the inner side surface 120 of the housing 100. The inner side surface 120 of the housing 100 may be a panel at the top of the housing 100. That is, X-rays can pass through the inner side surface 120 of the housing 100 and enter the detection surface of the X-ray detector 210. The ultrasonic detector 300 can be moved within the housing 100 as needed. The ultrasonic detector 300 can adhere to the inner wall of the housing 100, i.e., the inner side surface 120. When the tissue to be detected 540 is placed on the outer wall of the housing 100 opposite to the inner side surface 120 , the ultrasound probe 300 can detect the tissue to be detected 540 through the inner side surface 120 of the housing 100 .

[0046] The upper portion of the outer wall opposite to the inner side surface 120 of the housing 100 can be used to support the tissue to be tested. The surface where the inner side surface 120 of the housing 100 is located can directly or indirectly place the tissue to be tested 540 .

[0047] In one embodiment, the tissue to be examined may be breast tissue. The inner side surface 120 of the housing 100 may be a surface of the housing 100 or a plate structure disposed on the housing 100. The X-ray detector 210 is spaced apart from the plate surface of the housing 100 where the inner side surface 120 is located. The X-ray detector 210 can be used to receive X-rays. X-rays can be emitted by an X-ray emission source 220. The X-ray emission source 220 can be disposed on a side of the inner side surface 120 of the housing 100 away from the X-ray detector 210. That is, X-rays emitted by the X-ray emission source 220 can be transmitted to the X-ray detector 210 via the inner side surface 120 of the housing 100. When the tissue to be examined 540 is placed on the plate surface where the inner side surface 120 of the housing 100 is located, the X-rays emitted by the X-ray emission source 220 can sequentially pass through the tissue to be examined 540, the inner side surface 120 of the housing 100, and then enter the X-ray detector 210.

[0048] In one embodiment, the ultrasonic detector 300 is movably disposed in the housing 100 along a horizontal direction. The X-ray detector 210 is movably disposed in the accommodation space 110 along a vertical direction.

[0049] It is understood that the inner side surface 120 of the housing 100 and the X-ray detector 210 can be spaced apart. That is, a space is left between the inner side surface 120 of the housing 100 and the X-ray detector 210. The inner side surface 120 of the housing 100 and the X-ray detector 210 can be fixed relative to each other. The vertical distance between the inner side surface 120 of the housing 100 and the X-ray detector 210 can also be adjusted as needed. The ultrasound probe 300 can move in the horizontal plane between the inner side surface 120 of the housing 100 and the X-ray detector 210. When X-ray detection of the tissue to be detected 540 is required, the ultrasound probe 300 can be moved in the horizontal plane between the inner side surface 120 of the housing 100 and the X-ray detector 210, so that the ultrasound probe 300 is away from the tissue to be detected 540 and the X-ray detector 210. In other words, the ultrasound probe 300 will not block the X-ray detector 210 from receiving X-rays. At this time, the ultrasonic detector 300 does not affect the operation of the X-ray detector 210. When ultrasonic testing of the tissue to be tested 540 is required, the ultrasonic detector 300 can be moved between the X-ray detector 210 and the inner side surface 120 of the housing 100. Since the X-ray detector 210 does not need to operate at this time, the ultrasonic detector 300 can be moved above the X-ray detector 210 and can emit ultrasonic waves to test the tissue to be tested 540.

[0050] In one embodiment, the detection surface of the ultrasonic detector 300 may be parallel to the inner surface 120 of the housing 100. The path of the ultrasonic detector 300's planar motion between the X-ray detector 210 and the inner surface 120 of the housing 100 is not limited, as long as the ultrasonic detector 300 and the X-ray detector 210 do not interfere with each other when operating separately. A slide 411 may be provided in the plane between the X-ray detector 210 and the inner surface 120 of the housing 100. The ultrasonic detector 300 can slide on the slide 411. The X-ray detector 210 is movably disposed in the accommodating space 110 along a vertical direction. That is, when the inner surface 120 of the housing 100 is disposed horizontally, the X-ray detector 210 can move vertically toward or away from the inner surface 120 of the housing 100.

[0051] When performing X-ray detection on the tissue to be inspected 540, the X-ray detector 210 can be moved vertically, bringing it close to the inner side surface 120 of the housing 100. The proximity of the X-ray detector 210 to the inner side surface 120 of the housing 100 improves the accuracy of X-ray reception. When the X-ray detector 210 is no longer needed, it can be moved away from the inner side surface 120 of the housing 100. This allows for a larger space between the inner side surface 120 of the housing 100 and the X-ray detector 210. In this case, the ultrasound detector 300 can be moved horizontally between the X-ray detector 210 and the inner side surface 120 of the housing 100. The ultrasound detector 300 can then detect the tissue to be inspected 540 placed on the inner side surface 120 of the housing 100. It is understood that a vertically arranged slide rail can be provided within the accommodation space 110. The X-ray detector 210 can be slidably mounted on the slide rail. A plurality of latching structures can be spaced apart on the slide rail. The latching structures can limit the position of the X-ray detector 210 on the slide rail, thereby limiting the distance between the X-ray detector 210 and the inner side surface 120 of the housing 100.

[0052] In one embodiment, the detection device 10 further includes a first slide rail 410 arranged in a horizontal direction. The first slide rail 410 is arranged in the accommodating space 110. The first slide rail 410 is arranged between the inner side surface 120 of the cover 100 and the X-ray detector 210. The ultrasound detector 300 is slidably arranged on the first slide rail 410. The first slide rail 410 may include two spaced-apart slideways 411. The two slideways 411 may be respectively arranged in planes parallel to the inner side surface 120 of the cover 100. The ultrasound detector 300 may span the surfaces of the two slideways 411 and may slide on the surfaces of the slideways 411. It is understood that the ultrasound detector 300 may be connected to a motor. The motor may drive the ultrasound detector 300 to move on the surfaces of the two slideways 411.

[0053] In one embodiment, the X-ray detector may be fixed relative to the accommodating space 110 , and the ultrasound detector 300 may slide horizontally on the first slide rail 410 .

[0054] In one embodiment, the detection device 10 further includes a second slide rail 412. The second slide rail 412 is vertically disposed in the accommodating space 110. The X-ray detector 210 is slidably disposed on the second slide rail 412. The second slide rail 412 can be a single slide rail or two parallel slide rails spaced apart. The X-ray detector 210 can slide up and down along the slide rail to adjust the vertical distance between the X-ray detector 210 and the inner side surface 120 of the housing 100.

[0055] In one embodiment, the ultrasound probe 300 is in contact with the inner side surface 120 of the housing 100 located on the side of the accommodating space 110. That is, the ultrasound probe 300 is in contact with the inner wall of the inner side surface 120 of the housing 100. This means that the probe of the ultrasound probe 300 can be in contact with the surface of the inner side surface 120 of the housing 100 located in the accommodating space 110. The ultrasound probe 300 can slide along the surface of the inner side surface 120 of the housing 100 located in the accommodating space 110. Therefore, the ultrasound probe 300 is closer to the tissue 540 to be tested, resulting in better detection results. The ultrasound probe 300 is in contact with the inner side surface 120 of the housing 100 located on the side of the accommodating space 110. The inner side surface 120 of the housing 100 relatively defines the horizontal plane of movement of the ultrasound probe 300, thereby facilitating control of the movement of the ultrasound probe 300. At the same time, the ultrasonic detector 300 fits in contact with the inner side surface 120 of the housing 100 on one side of the accommodating space 110 , which can further improve the compactness of the detection device 10 and reduce the space occupied by the detection device 10 .

[0056] In one embodiment, the ultrasound probe 300 is provided with a groove 310 near the inner side 120 of the housing 100. The groove 310 is used to accommodate an ultrasonic coupling agent. The shape of the groove 310 is not limited, as long as it can be filled with the ultrasonic coupling agent. The cross-section of the groove 310 can be rectangular, circular, elliptical, or polygonal, among others. The groove 310 can be sealed. For example, a sealing ring can be provided at the opening of the groove 310, and then the opening of the groove 310 can be attached to the inner side 120 of the housing 100 to achieve a sealed effect. In one embodiment, the groove 310 can also be airtight by evacuating the air inside. It is understood that during an ultrasonic examination, air between the probe of the ultrasound probe 300 and the patient's skin can hinder the transmission of ultrasonic waves into the body. To obtain high-quality, clear images, the coupling agent is required to connect the probe to the patient's body surface. Sealing the groove 310 prevents air from obstructing the transmission of ultrasonic waves into the body, thereby improving the detection effect.

[0057] In one embodiment, the ultrasonic coupling agent is a solid coupling agent. The shape of the solid coupling agent can be the same as that of the groove 310, thereby facilitating the removal and placement of the solid coupling agent from the groove 310. The solid coupling agent is less likely to dissolve in air, thereby improving detection effectiveness. The solid coupling agent is also easier to transport. In one embodiment, the ultrasonic coupling agent can be made primarily from konjac flour.

[0058] In one embodiment, the ultrasonic coupling agent may also be a liquid coupling agent. When a liquid coupling agent is used, a liquid sealing structure may be provided in the groove. The liquid coupling agent may be injected into the groove via a hydraulic system.

[0059] In one embodiment, the detection device 10 further includes a scraping device 320. The scraping device 320 is slidably disposed on the inner side surface 120 of the housing 100. The scraping device 320 is used to scrape away ultrasonic coupling agent remaining on the inner side surface of the housing 100. When the tissue to be detected 540 is detected using the ultrasonic probe 300, ultrasonic coupling agent is typically required. After the tissue to be detected 540 leaves the inner side surface 120 of the housing 100, the scraping device 320 can scrape away the ultrasonic coupling agent remaining on the inner side surface 120.

[0060] In one embodiment, the scraping device 320 may be disposed along the width direction of the inner side surface 120 of the housing 100 , and the surface of the scraping device 320 in contact with the inner side surface 120 of the housing 100 may be made of silicone material.

[0061] In one embodiment, the detection device 10 further includes a storage device 330. The storage device 330 is disposed on one side of the cover 100. The storage device 330 is used to store the ultrasonic coupling agent scraped by the scraping device 320. The storage device 330 is disposed at the edge of the cover 100. The storage device 330 may be a cubic structure with an opening, or a bag-like structure with an opening fixed to the edge of the cover 100. When the ultrasonic coupling agent remaining on the surface of the inner side surface 120 of the cover 100 is scraped to the edge of the inner side surface 120 of the cover 100 by the scraping device 320, the ultrasonic coupling agent may fall into the storage device 330. The ultrasonic coupling agent may be recovered through the storage device 330 to avoid waste.

[0062] In one embodiment, the detection device is used in a mammography machine.
