[0002] When facing some seriously injured patients, such as multiple fractures, the patient can only lie on the bed, but at present, many medical devices cannot be shot at the best angle due to their own size or shape. At this time, the patient can only be moved to meet the shooting conditions, which brings great pain to the patient and is very inconvenient. Moreover, the shooting angle of the medical device is limited, there is a shooting dead angle, which affects the accuracy of the imaging result. SUMMARY
[0003] Therefore, it is necessary to provide an X-ray imaging device which can realize arbitrary angle shooting in view of the problem of shooting dead angle of the existing medical device.
[0004] The above-mentioned purpose is realized by the following technical scheme:
[0005] An X-ray imaging device, comprising:
[0006] a track defining at least a part of a sphere;
[0007] a radiation source slidably disposed on the track, the radiation source configured to emit X-rays; and a detector slidably disposed on the track opposite the radiation source, the detector configured to receive X-rays that have passed through an object.
[0008] In one embodiment, the track is a spherical track.
[0009] In one embodiment, the track comprises a first track and a second track, wherein each of the first track and the second track is partially spherical, wherein the radiation source is disposed on the first track and the detector is disposed on the second track.
[0010] In one embodiment, the detector comprises a flat panel detector.
[0011] In one embodiment, the X-ray imaging device is a digital radiography system, a cone beam CT system, a mammography system, or a digital breast tomosynthesis system.
[0012] In one embodiment, the X-ray imaging device further comprises a spherical housing assembly having a receiving cavity configured to receive the object.
[0013] The radiation source and the detector are disposed on the inner wall of the housing assembly, and the radiation source and the detector are movable along the inner wall of the housing assembly.
[0014] In one embodiment, the housing assembly includes:
[0015] The outer casing; and
[0016] An openable door is provided on the housing.
[0017] In one embodiment, the housing assembly is at least partially made of a magnetic material and is capable of attracting the radiation source and the detector, allowing the radiation source and the detector to move along the inner wall of the housing assembly.
[0018] In one embodiment, the X-ray imaging device further includes a first adsorption element and a second adsorption element;
[0019] The radiation source is adsorbed onto the inner wall of the housing assembly by the first adsorption element, and the first adsorption element moves synchronously with the radiation source;
[0020] The detector is adsorbed onto the inner wall of the housing assembly by the second adsorption element, and the second adsorption element moves synchronously with the detector.
[0021] In one embodiment, both the first adsorption element and the second adsorption element are disposed on the inner wall of the housing assembly, or both the first adsorption element and the second adsorption element are disposed on the outer wall of the housing assembly.
[0022] In one embodiment, the surface of the radiation source is in contact with the inner wall of the housing assembly; or, the radiation source has a first guide that abuts against the housing via the first guide.

[0026] By adopting the above technical solution, the present invention has at least the following technical effects:
[0027] The X-ray imaging device of the present invention allows the X-ray source to image the target at any angle along at least a partially spherical trajectory, while the detector receives the X-rays passing through the target at a corresponding angle along the same trajectory. This effectively solves the problem of blind spots in current medical equipment. In this way, the detector can be set at any imaging angle without moving the target, reducing the pain experienced by the target during imaging. Simultaneously, it ensures that the target is imaged at the optimal angle, avoiding blind spots and guaranteeing the accuracy of the imaging results. Attached Figure Description

Therefore, they should not be construed as limitations on the invention.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0045] See Figure 1 This invention provides an X-ray imaging device 100. This X-ray imaging device 100 can scan the location of lesions in a patient to generate an image of the lesion location, facilitating diagnosis by medical personnel based on the image. Furthermore, the X-ray imaging device 100 of this invention allows for arbitrary setting of the imaging angle without moving the patient, reducing patient discomfort during imaging. Simultaneously, it ensures optimal imaging angles, avoiding blind spots and guaranteeing accurate imaging results.
[0046] In one embodiment, the X-ray imaging apparatus 100 includes a track, a radiation source 110, and a detector 120. The track defines at least a portion of a sphere. The radiation source 110 is slidably disposed on the track and is used to emit X-rays. The detector 120 is slidably disposed on the track relative to the radiation source 110 and is used to receive X-rays passing through a target.
[0047] Since the orbit is at least a portion of a sphere, the radiation source 110 and detector 120 have at least a partially spherical trajectory. The radiation source 110 is used to emit X-rays toward a target. Understandably, the target here refers to a patient. The detector 120 can move synchronously with the radiation source 110, and the detector 120 is located within the projection area of the radiation source 110 to receive X-rays passing through the target. In this embodiment, the detector radiation source 110 includes an X-ray tube. Exemplarily, the detector 120 is a flat panel detector.
[0048] The X-ray source 110 can move freely along at least a portion of a spherical track, avoiding limitations on its imaging angle and enabling imaging from any angle. This allows medical personnel to adjust the imaging angle according to the location of the patient's lesion, ensuring accurate imaging of the lesion. Simultaneously, the detector 120 can move synchronously with the X-ray source 110 along at least a portion of a spherical track, receiving X-rays emitted from the source 110 at any angle. The detector 120 receives the X-rays passing through the target, processes the X-ray information, and creates an image, facilitating diagnosis by doctors.
[0049] When the radiation source 110 moves, the detector 120 can adjust its position according to the focal position of the radiation source 110 and the intensity of the radiation emitted by the radiation source 110, so that the detector 120 is in the optimal position within the projection area of the radiation source 110, so as to ensure that the detector 120 can accurately receive the radiation passing through the patient's lesion, thereby improving the image quality and facilitating the doctor's diagnosis.
[0050] Furthermore, the X-ray source 110 and detector 120 can slide in any or multiple directions along the track. In this way, the X-ray source 110 and detector 120 can slide along multiple circular tracks with the same center, or they can move along irregular spherical tracks, which increases the elasticity of the motion and makes imaging more flexible.
[0051] The X-ray imaging device 100 of the present invention includes an X-ray source 110 that can image a target at any angle along a trajectory that is at least partially spherical, and a detector 120 that can receive X-rays passing through the target at a corresponding angle along the same trajectory. This effectively solves the problem of blind spots in current medical equipment. In this way, the detector 120 can be set at any imaging angle without moving the target, reducing the pain experienced by the target during imaging. Simultaneously, it ensures that the target is imaged at the optimal imaging angle, avoiding blind spots and guaranteeing the accuracy of the imaging results.
[0052] In one embodiment, the track is a spherical track. This allows both the X-ray source 110 and the detector 120 to move along the spherical track. This enables the X-ray source 110 to image the target from any angle, avoiding blind spots, and allows the detector 120 to receive X-rays passing through the target at a corresponding angle, ensuring image quality.
[0053] Of course, in other embodiments of the present invention, the tracks may also be arranged in a split configuration. For example, the tracks include a first track and a second track, both of which are partially spherical. The radiation source 110 is disposed on the first track, and the detector 120 is disposed on the second track. Optionally, the radiation source 110 may also move to the second track, and correspondingly, the detector 120 may move to the first track.
[0054] Understandably, the first and second orbitals can have the same shape. Of course, the first and second orbitals can also have different shapes, as long as the X-ray source 110 and detector 120 are aligned when rotating. This ensures that detector 120 can accurately receive X-rays passing through the target. Furthermore, the first and second orbitals can form part of a sphere or a complete sphere.
[0055] In one embodiment, the X-ray imaging device includes, but is not limited to, a digital X-ray imaging system, a cone-beam CT system, a mammography system, or a digital breast tomography system, and may also be other types of imaging devices.
[0056] See Figure 1 and Figure 2 In one embodiment, the X-ray imaging device 100 further includes a spherical housing assembly 130 with a receiving cavity for accommodating a target. Both the radiation source 110 and the detector 120 are disposed on the inner wall of the housing assembly 130, and both are movable along the inner wall of the housing assembly 130. The housing assembly 130 provides protection, preventing radiation leakage from the detector 120 and ensuring operational safety. The housing assembly 130 also provides protection, preventing contact with internal components during use and improving reliability. Understandably, the target can be placed in the receiving cavity of the housing assembly 130 via a bed, or can directly enter the receiving cavity. In this embodiment, the target, i.e., the patient, can be placed in the receiving cavity via a bed or can stand in the receiving cavity.
[0057] Furthermore, the housing assembly 130 is spherical, and both the radiation source 110 and the detector 120 are mounted on the inner wall of the housing assembly 130. When the radiation source 110 moves along the inner wall of the housing assembly 130, the detector 120 moves along the inner wall of the housing assembly 130 along with the radiation source 110. The spherical housing assembly 130 ensures the accuracy of the movement trajectories of the radiation source 110 and the detector 120.
[0058] Understandably, the X-ray source 110 and the detector 120 can slide freely on the inner wall of the housing assembly 130, as long as the X-ray source 110 and the detector 120 are relative to each other, in order to ensure the image imaging quality.
[0059] Furthermore, the radiation source 110 can rotate relative to the inner wall of the housing assembly 130, and the detector 120 moves with the rotation of the radiation source 110. That is, when the position of the radiation source 110 remains unchanged, the angle of the radiation source 110 relative to the inner wall of the housing assembly 130 can be adjusted accordingly. In this way, the range of radiation emitted by the radiation source 110 will also change accordingly, and the position of the detector 120 can be adjusted accordingly based on the range of radiation emitted by the radiation source 110 to ensure that the detector 120 can accurately receive the radiation passing through the patient and ensure image quality.
[0060] In one embodiment, the radiation source 110 and the detector 120 are linked. That is, the radiation source 110 and the detector 120 move synchronously. This ensures that the radiation emitted by the radiation source 110 is always received by the detector 120. Optionally, the radiation source 110 and the detector 120 can be controlled by the same control program or the same drive unit.
[0061] Understandably, during the alignment of an X-ray imaging device, the X-ray source 110 projects X-rays onto the detector 120. For example, the center of the X-ray beam can be aligned with the center of the detector 120 by aligning the center of the crosshairs of the visible light field with the center of the detector 120, thus ensuring the stability of the imaging and the accuracy of the image data. Selectively, by observing the grayscale image obtained by the detector 120, it can be determined whether the X-ray source 110 and the detector 120 are aligned.
[0062] In one embodiment, the housing assembly 130 includes a housing 131 and an openable door 132. The openable door 132 is sleekly disposed on the housing 131 for allowing the target to enter or exit. The housing 131 is a spherical hollow shell to accommodate a bed containing the target, a radiation source 110, and a detector 120, etc. When the openable door 132 is closed, it ensures the sealing performance of the housing 131, preventing radiation leakage during imaging. Furthermore, the housing 131 may also be part of a sphere.
[0063] When imaging the patient's lesion location, the bed carrying the target is pushed into the outer casing 131 through a door. After the medical staff exits the outer casing 131, the openable door 132 closes to seal the outer casing 131. Then, the radiation source 110 images the target lesion location. The radiation source 110 emits X-rays that pass through the target imaging location and are received by the detector 120. After imaging is completed, the openable door 132 is opened, and the bed carrying the target is pushed out of the outer casing 131, completing the imaging operation.
[0064] Understandably, before taking the picture, the position of the radiation source 110 on the inner wall of the outer casing 131 can be adjusted arbitrarily so that the radiation source 110 can take the picture of the target lesion at the optimal angle. For different lesion locations, the shooting angle of the radiation source 110 is different. By moving the radiation source 110 along the inner wall of the outer casing 131, it is possible to take the picture at any angle to adapt to different conditions.
[0065] Optionally, since the outer casing 131 is spherical, it can have a platform at its bottom near the ground during installation. This allows the outer casing 131 to be placed on the ground without rotating, ensuring the stability of the casing assembly 130 and consequently, the stability during shooting. Of course, in other embodiments of the invention, the outer casing 131 can also be mounted on the ground using a bracket. The bracket can act as a limiter, preventing the outer casing 131 from rotating relative to the opposite side, thus ensuring the stability of the casing assembly 130 and consequently, the stability during shooting.
[0066] Optionally, the interior of the outer casing 131 can also be configured as a sterile environment. This allows medical personnel to perform surgery directly inside the casing 131. In other words, the location of the patient's lesion is imaged in real time through the cooperation of the radiation source 110 and the detector 120, and medical personnel perform surgery based on the imaged lesion location, ensuring the safety of the procedure.
[0067] See Figure 3 In one embodiment of the present invention, the housing assembly 130 is at least partially made of a magnetic material and can adsorb the radiation source 110 and the detector 120, allowing the radiation source 110 and the detector 120 to move along the inner wall of the housing assembly 130. That is, because the housing assembly 130 has an adsorption function, the radiation source 110 and the detector 120 can be directly adsorbed onto the inner wall of the housing assembly 130 without the need for other auxiliary adsorption components. In other words, the outer shell 131 itself is magnetic or made of an adsorption-capable material, and the radiation source 110 and the detector 120 can be adsorbed onto the inner wall of the outer shell 131.
[0068] Optionally, the surface of the X-ray source 110 is in contact with the inner wall of the housing assembly 130. That is, the surface of the X-ray source 110 in contact with the inner wall of the housing assembly 130 is arc-shaped. This ensures a tight fit between the X-ray source 110 and the housing assembly 130, facilitating movement of the X-ray source 110 along the inner wall of the housing assembly 130, thus enabling imaging from any angle. Of course, in other embodiments of the invention, the X-ray source 110 has a first guide member 150, through which the X-ray source 110 abuts against the housing 131. The first guide member 150 serves a guiding function, facilitating movement of the X-ray source 110 along the housing assembly 130. Exemplarily, the first guide member 150 includes a caster wheel, etc.
[0069] See Figure 4 In another embodiment of the present invention, the X-ray imaging device 100 further includes a first adsorption member 140 and a second adsorption member. The X-ray source 110 is adsorbed onto the inner wall of the housing assembly 130 via the first adsorption member 140, and the first adsorption member 140 moves synchronously with the X-ray source 110. The detector 120 is adsorbed onto the inner wall of the housing assembly 130 via the second adsorption member, and the second adsorption member moves synchronously with the detector 120. That is, the X-ray source 110 is fixed by the first adsorption member 140, and the detector 120 is fixed by the second adsorption member.
[0070] Understandably, the X-ray source 110 can drive the first adsorption element 140 to move synchronously, and the detector 120 can drive the second adsorption element to move synchronously. For example, when the X-ray source 110 moves along the inner wall of the housing assembly 130, it can drive the first adsorption element 140 to move synchronously. When the detector 120 moves along the inner wall of the housing assembly 130, it can drive the second adsorption element to move synchronously. Of course, the first adsorption element 140 can also drive the X-ray source 110 to move synchronously, and the second adsorption element can drive the detector 120 to move synchronously. For example, the first adsorption element 140 can move along the housing assembly 130, thereby driving the first adsorption element to move along the inner wall of the housing assembly 130. Correspondingly, the second adsorption element is similarly configured to move along the inner wall of the housing assembly 130.
[0071] In one embodiment, both the first adsorption member 140 and the second adsorption member are disposed on the outer wall of the housing assembly 130. That is, the first adsorption member 140 is located on the outer wall of the housing assembly 130, and can adsorb the radiation source 110 onto the inner wall of the housing assembly 130. In this case, the radiation source 110 and the first adsorption member 140 are respectively located on opposite sides of the housing assembly 130. Correspondingly, the second adsorption member and the detector 120 are disposed in the same manner. Of course, in other embodiments of the present invention, both the first adsorption member 140 and the second adsorption member are disposed on the inner wall of the housing assembly 130. That is, the radiation source 110 is mounted on the inner wall of the housing assembly 130 via the first adsorption member 140. Correspondingly, the second adsorption member and the detector 120 are disposed in the same manner.
[0072] In one embodiment, the first adsorption member 140 and the second adsorption member abut against the housing assembly 130 via a universal joint 141. This facilitates the movement of the first adsorption member 140 and the second adsorption member relative to the housing assembly 130, allowing the radiation source 110 and the detector 120 to move at any angle along the inner wall of the housing assembly 130. Of course, in other embodiments of the invention, the first adsorption member 140 and the second adsorption member may also directly abut against the housing assembly 130, and the surfaces of the first adsorption member 140 and the second adsorption member in contact with the housing assembly 130 may be arc-shaped to facilitate movement of the first adsorption member 140 and the second adsorption member relative to the housing assembly 130. Exemplarily, the universal joint 141 may be a caster wheel or the like.
[0073] In one embodiment, one side surface of the detector 120 is in contact with the inner wall of the housing 131. That is, the surface of the detector 120 that contacts the inner wall of the housing assembly 130 is arc-shaped. This ensures a tight fit between the detector 120 and the housing assembly 130, facilitating movement of the detector 120 along the inner wall of the housing assembly 130 to receive rays at any angle. Of course, in other embodiments of the invention, the detector 120 has a second guide member, through which it abuts against the housing 131. The second guide member serves a guiding function, facilitating movement of the detector 120 along the housing assembly 130. Exemplarily, the second guide member includes a caster wheel, etc.
[0074] In one embodiment, the X-ray imaging device 100 further includes a control component connected to the radiation source 110 for adjusting the position of the radiation source 110. Specifically, the control component can adjust the position of the radiation source 110 on the track or the inner wall of the housing assembly 130. The control component is also connected to the detector 120 for adjusting the position of the detector 120. Specifically, the control component can adjust the position of the detector 120 on the track or the inner wall of the housing assembly 130. The control component can remotely control the positions of the radiation source 110 and the detector 120. Exemplarily, the control component is a remote controller. Of course, the control component can also control the radiation source 110 to emit radiation and control the detector 120 to transmit the received radiation to the image processor.
[0075] Optionally, the control unit can be connected to the radiation source 110 and the detector 120 via a wired or wireless connection.
[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.
[0077] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
