Description

Technical Field

[0001] This invention relates to ultrasound imaging devices, and more particularly to a head-mounted ultrasound image display device and its ultrasound imaging system. Background Technology

[0002] Augmented Reality (AR) technology has become a widely discussed technological hotspot in recent years. Its near-eye display system (AR glasses) can use a series of optical imaging elements to form a distant virtual image of pixels on the display and project it into the viewer's eyes. Through AR glasses, one can see both the real external world and virtual information. It usually integrates virtual information and real scenes, complementing and "enhancing" each other.

[0003] AR technology has been applied to various scenarios. However, AR technology overlays virtual information onto real-world scenes. Real-world scenes are often complex and disorganized. In the field of ultrasound imaging, ultrasound images need to be clearly displayed so that doctors can comprehensively and clearly view various features and details, thereby making accurate diagnoses. In this case, complex and disorganized real-world scenes can severely interfere with ultrasound images, seriously affecting doctors' ability to interpret them. Summary of the Invention

[0125] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0126] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0127] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0128] like Figure 1 As shown, in one embodiment of the present invention, a head-mounted ultrasound image display device 100 is provided. The head-mounted ultrasound image display device 100 may include a support frame 1, a first lens 2, and a second lens 3. The support frame 1 can be the main support frame of the head-mounted ultrasound image display device 100, which can be worn on the user's head. For example, as... Figure 1 As shown, the support frame can be a frame similar in shape to eyeglasses, which can be worn on the user's head via two clamping parts 10. In other embodiments, the support frame can also be of other shapes, or worn on the user's head in a manner different from the clamping parts 10, such as via elastic bands, cords, etc.

[0129] The first lens 2 and the second lens 3 can be directly or indirectly mounted on the support frame 1 via other intermediate components. When the ultrasound image display device 100 is worn on the user's head, the first lens 2 can be located in front of the user's first eye, and the second lens 3 can be located in front of the user's second eye. Light from the external scene can pass through the first lens 2 and enter the user's first eye, and pass through the second lens 3 and enter the user's second eye, allowing the user to see the external scene through the first lens 2 and the second lens 3. The first lens 2 and the second lens 3 can be any suitable type of lens, such as a concave lens, a convex lens, a plano lens, or other suitable type of lens.

[0130] like Figure 2 As shown, the head-mounted ultrasound image display device 100 also includes a first display screen 4 and a first optical component 5. The first lens 2 may include a transparent area 21 and a first opaque area 20 formed on the first lens 2.

[0131] In this document, the areas referred to as "opaque" regions (such as the first opaque region 20 and the second opaque region 30 described below) do not necessarily mean that they are completely or absolutely opaque. These regions can be completely opaque or partially opaque, as long as they can block light from the external environment to a certain extent, thus preventing external light from severely affecting the user's viewing of ultrasound images (detailed below), and meet the user's requirements for viewing ultrasound images, they are uniformly referred to as opaque regions in this document. Similarly, the areas referred to as "transparent" regions (such as the transparent region 21 in the first lens 2 and the transparent region 31 in the second lens 3 described below) do not necessarily mean that they are completely or absolutely transparent. These regions can be completely transparent or partially transparent, as long as they meet the user's requirements for viewing the external environment, they are uniformly referred to as transparent regions in this document.

[0132] The first display screen 4 can be mounted directly or indirectly on the support frame 1 via other intermediate components. The first display screen 4 can be connected to an external device (not shown) via wired or wireless means. This external device can be a device that stores or is capable of acquiring ultrasound images, such as an ultrasound imaging device, an ultrasound workstation, various mobile terminals (phones, tablets, etc.), or other electronic devices. The external device can be located locally or remotely and connected to the local device via various wired or wireless networks. The first display screen 4 can acquire ultrasound images from the external device and display them on the first display screen 4; alternatively, the external device can send ultrasound images to the first display screen 4 and display them. Here, the ultrasound image displayed on the first display screen 4 can be a static ultrasound image or an ultrasound video image.

[0133] The first display screen 4 can be any suitable display screen. For example, it can be a self-emissive active device, such as a light-emitting diode panel (e.g., micro-OLED or micro-LED, etc.), or a liquid crystal display screen that requires external light source illumination (including transmissive LCD and reflective LCOS), or a digital micromirror array (DMD, the core of DLP) and laser beam scanner (LBS) based on microelectromechanical systems (MEMS) technology, etc.

[0134] The first optical component 5 can be mounted directly or indirectly on the support frame 1 via other intermediate components. The first optical component 5 can guide the light 7 from the first display screen 4 into the user's first eye 6, thus, see... Figure 3 The ultrasound image displayed on the first display screen can form a virtual image (hereinafter referred to as the first ultrasound image virtual image) 23 relative to the first eye 6 via the first optical component 5. The intersection region 22 of the viewing angle region 25 of the first ultrasound image virtual image 23 relative to the first eye 6 and the first lens 2 is located within the first opaque region 20 of the first lens 2. Here, the viewing angle region 25 of the first ultrasound image virtual image 23 relative to the first eye 6 refers to the viewing angle boundary of the first ultrasound image virtual image 23 relative to the first eye 6 (i.e.,...). Figure 3 The area shown is between the line connecting the first eye 6 to the edge of the first ultrasound image virtual image 23. Since the intersection area 22 of the first ultrasound image virtual image 23 with the first lens 2, which is located in the first opaque area 20 of the first lens 2, will fall within the first opaque area 20 when the user observes it. Thus, the first ultrasound image virtual image seen by the user will be in a background with no or at least no external ambient light, so it will not or will not seriously affect the user's observation of the first ultrasound image.

[0135] Simultaneously, light from the external environment can pass through the transparent area 21 of the first lens 2 and (or bypass) the first optical component 5 to enter the first eye 6, thus providing a reference. Figure 3 and Figure 5 This allows the user to see both the first ultrasound image virtual image 23 in a background with no or at least no external ambient light, and the external environment, such as the target 50 (e.g., a human or animal) and the probe 60. Figure 5This is a schematic diagram of the scene seen by the user through the first lens 2. The left side shows the first ultrasound image virtual image 23 falling into the first opaque area 20. It can be seen that the background of the first ultrasound image virtual image 23 in this example is pure black, without the interference of the external real environment. On the right side, the real environment can be seen, such as the position and orientation of the examination target 50 and the probe 60 on the examination target 50. This makes it easier for the user to view the ultrasound image and the condition of the examination target and probe at the same time, making it easier for the user to make a more accurate diagnosis.

[0136] Although Figure 5 The first opaque region 20 of the first lens 2 is shown to be rectangular in shape, but the invention is not limited thereto. The shape of the first opaque region 20 (and the second opaque region of the second lens described below) can be any shape depending on the actual situation.

[0137] Although Figure 5 In the present invention, the transparent region 21 and the first opaque region 20 of the first lens 2 are arranged side by side. However, in embodiments of the present invention, the transparent region 21 and its first opaque region 20 of the first lens 2 (and the transparent region 31 and its second opaque region 30 of the second lens 3 described below) can be in any suitable positional relationship, and their relative sizes can also be any suitable relative sizes. For example, they can be arranged side by side, top by bottom, one surrounding the other, one partially surrounding the other, etc.; they can be equal in size or unequal in size. No limitation is made herein.

[0138] The optical component 5 can be any suitable optical element or any suitable optical structure, as long as it can achieve the optical function described herein. For example, it can be a prism, a freeform mirror, an arrayed waveguide element, a diffractive waveguide element, or other suitable optical element, or a combination of these optical elements.

[0139] refer to Figure 4 In one embodiment, the first opaque region 20 of the first lens 2 can be formed by a first light-shielding device 26 disposed on the outer or inner side of the first lens 2. This first light-shielding device 26 can block light from the external environment from entering a portion of the first lens 2 (if the first light-shielding device 26 is disposed on the outer side of the first lens 2, such as...). Figure 4(As shown) or blocking light from the external real environment that has passed through a portion of the first lens 2 from continuing to enter the first eye (when the first light-shielding device 26 is disposed inside the first lens 2, not shown), thereby causing this "partial area" to form the first opaque area 20 as described herein, while the remaining portion forms the aforementioned transparent area 21. The first light-shielding device 26 can be any suitable type of light-shielding element, such as a light-shielding plate, light-shielding film, polarizing film, or other suitable element.

[0140] In one embodiment, the first light-shielding device 26 can be detachably mounted on the first lens 2 or the support frame 1. In this way, when needed, different first light-shielding devices (e.g., different shapes, different sizes, different light-shielding performance, different opacities, etc.) can be replaced according to actual needs to obtain a first opaque area 20 that meets different needs.

[0141] In one embodiment, the first light-shielding device 26 can be rotatably connected to the support frame 1 or the first lens 2 via a first rotating joint (not shown), and can rotate between a shielded state that shields at least a portion of the first lens 2 to form the first opaque region 20 and an unshielded state that does not shield at least a portion of the first lens 2. Thus, when the user needs to view an ultrasound image, the first light-shielding device 26 can be rotated to the shielded state, thereby forming the first opaque region 20 on the first lens 2, allowing for a better view of the first ultrasound image virtual image 23 falling on the first opaque region 20. When the user needs to view the external real environment without viewing the ultrasound image, the first light-shielding device 26 can be rotated to the unshielded state, giving the user a wider field of view to view the real environment.

[0142] Here, the first rotating joint can be any suitable rotating joint, such as a rotating joint formed by a shaft and a bearing, a rotating joint formed by a shaft and a shaft hole, etc. The rotation of the first light-shielding device 26 via the first rotating joint can be manually driven by the user or driven by a drive device (e.g., a motor, etc.) provided in the head-mounted ultrasound image display device 100.

[0143] In one embodiment, the first light-shielding device 26 can be movably connected to the support frame 1 or the first lens 2 via a first movable joint (not shown), and can move between a shielded state that shields at least a portion of the first lens 2 to form the first opaque region 20 and an unshielded state that does not shield at least a portion of the first lens 2. Thus, when the user needs to view an ultrasound image, the first light-shielding device 26 can be moved to the shielded state, thereby forming the first opaque region 20 on the first lens 2, allowing for a better view of the first ultrasound image virtual image 23 falling on the first opaque region 20. When the user needs to view the external real environment without viewing the ultrasound image, the first light-shielding device 26 can be moved to the unshielded state, giving the user a wider field of view to view the real environment.

[0144] In one embodiment, the first light-shielding device 26 can be movably connected to the support frame 1 or the first lens 2 via a first sliding joint (not shown), and can move relative to the first lens 2. This allows for flexible adjustment of the position and / or size of the first light-shielding device 26 relative to the first lens 2 as needed, thereby adjusting the position and / or size of the first opaque area 20 on the first lens 2.

[0145] For example, in one embodiment, the first light-shielding device 26 can be moved as a whole relative to the first lens 2, so that the position of the first opaque area 20 on the first lens 2 can be easily adjusted.

[0146] Alternatively, in one embodiment, the first light-blocking device 26 can move relative to the first lens 2 between a retracted state (e.g., a fully retracted or partially retracted state) and an extended state (e.g., a fully extended or partially extended state) (like a curtain or a camera shutter). In the fully retracted state, the first light-blocking device 26 blocks a smaller area than in the fully extended state. The first light-blocking device 26 can be adjusted to any state between the fully retracted and fully extended states. This allows for convenient adjustment of the size of the first opaque area 20 on the first lens 2.

[0147] Here, the first moving pair in the aforementioned embodiments can be any suitable moving pair, such as a moving pair formed by a slide rail and a slider, a moving pair formed by a slide rod and a slider, a moving pair formed by a slider and a lead screw, a moving pair formed by a guide rail and a guide groove, a moving pair similar to a camera shutter structure, and so on. The movement of the first light-shielding device 26 via the first moving pair can be manually driven by the user or driven by a driving device (e.g., a motor, etc.) provided in the head-mounted ultrasound image display device 100.

[0148] In one embodiment, the first light-shielding device 26 may include a plurality of sub-light-shielding units (not shown) and a rotating or moving device (not shown). The rotating or moving device can drive the plurality of sub-light-shielding units to rotate or move between a first state and a second state. In the first state, the plurality of sub-light-shielding units are in close contact with each other, blocking light from passing through. In the second state, the plurality of sub-light-shielding units are spaced apart by a certain distance, allowing at least a portion of light to pass through (similar to a rotatable venetian blind structure or a camera shutter structure). This allows for convenient adjustment of the amount of light allowed to pass through the first light-shielding device 26 or the size of the area allowed to pass through, thereby adjusting the opacity of the first light-shielding device 26 or the size of the first opaque area 20. The rotating or moving device can be any suitable rotating or moving device, such as those found in venetian blind or camera shutter structures, and will not be described in detail here. The rotating or moving device can be manually driven by the user or driven by a drive device (e.g., a motor, etc.) provided in the head-mounted ultrasonic image display device 100.

[0149] In one embodiment, the first light-blocking device 26 may include a rotating device (not shown). This rotating device can drive the first light-blocking device to rotate between a first state and a second state, wherein in the first state, the first light-blocking device blocks more light than in the second state. For example, the first state and the second state may correspond to a first angle and a second angle, respectively. At the first angle, compared to the second angle, the first light-blocking device can allow less light to pass through, such as by reflecting, absorbing, or scattering more incident light, etc. For example, in the first state, it can completely block or block a predetermined ratio of light from passing through, while in the second state, it can completely allow or allow a predetermined ratio of light to pass through, etc. This allows for convenient adjustment of the opacity of the first and second opaque regions. The rotating device can be any suitable rotating device, which will not be detailed here. The rotating device can be manually driven by the user or driven by a drive device (e.g., a motor, etc.) provided in the head-mounted ultrasound image display device 100.

[0150] In one embodiment, the first light-shielding device 26 may be a light-shielding film or a polarizing film, which may be fixedly bonded to the first lens 2, for example, bonded to a specific position on the inner or outer side of the first lens 2. Alternatively, the light-shielding film or polarizing film may be detachably bonded to the first lens 2. In this way, when needed, other light-shielding films or polarizing films can be replaced as required, thereby conveniently adjusting the position, size, and / or shape of the formed first opaque region 20.

[0151] In one embodiment, the first opaque region 26 may be formed by an opaque layer (not shown) disposed inside the first lens 2. Alternatively, in one embodiment, the first opaque region 26 may be made of an opaque material.

[0152] The second lens 3 and its related structures will now be described. In embodiments of the present invention, the second lens 3 and its related structures are similar to the first lens 2 and its related structures described above.

[0153] like Figure 3 As shown, the head-mounted ultrasound image display device 100 also includes a second display screen (not shown) and a second optical component (not shown). The second lens 3 may include a transparent region 31 and a second opaque region 30 formed on the second lens 3.

[0154] The second display screen can be mounted directly or indirectly on the support frame 1 via other intermediate components. The second display screen can be connected to the aforementioned external device via wired or wireless means. The second display screen can acquire ultrasound images from the external device and display them on its own screen; alternatively, the external device can send ultrasound images to the second display screen for display. Here, the ultrasound image displayed on the second display screen 4 can be a static ultrasound image or an ultrasound video image. The ultrasound image displayed on the second display screen can be the same as the ultrasound image displayed on the first display screen 4 described above.

[0155] The second display screen can be any suitable display screen. For example, it can be a self-emissive active device, such as a light-emitting diode panel (e.g., micro-OLED or micro-LED, etc.), or a liquid crystal display screen that requires external light source illumination (including transmissive LCD and reflective LCOS), or a digital micromirror array (DMD, the core of DLP) and laser beam scanner (LBS) based on microelectromechanical systems (MEMS) technology, etc.

[0156] The second optical component can be mounted directly or indirectly on the support frame 1 via other intermediate elements. The second optical component guides light from the second display screen into the user's second eye 9, thus, see [reference needed]. Figure 3 The ultrasound image displayed on the second display screen can form a virtual image (hereinafter referred to as the second ultrasound image virtual image) 33 relative to the second eye 9 via the second optical component. The intersection region 32 of the viewing angle region 35 of the second ultrasound image virtual image 33 relative to the second eye 9 and the second lens 3 is located within the second opaque region 30 of the second lens 3. Here, the viewing angle region 35 of the second ultrasound image virtual image 33 relative to the second eye 9 refers to the viewing angle boundary of the second ultrasound image virtual image 33 relative to the second eye 9 (i.e.,...). Figure 3The area shown is between the line connecting the second eye 9 to the edge of the second ultrasound image virtual image 33. Since the intersection area 32 where the second ultrasound image virtual image 33 intersects with the second lens 3 at the viewing angle area 35 of the second eye 9 is located in the second opaque area 30 of the second lens 3, when the user observes, the second ultrasound image virtual image 33 seen by the second eye will fall in the second opaque area 30. In this way, the second ultrasound image virtual image seen by the user will be in a background with no or at least no external ambient light, so it will not or will not seriously affect the user's observation of the second ultrasound image.

[0157] Simultaneously, light from the external environment can pass through the transparent area 31 of the second lens 3 and (or bypass) the second optical component to enter the second eye 9. This allows the user to see both the second ultrasound image virtual image 33 against a background completely devoid of or at least partially devoid of external ambient light, and the external environment itself, such as the examination target 50 (e.g., a human or animal) and the probe 60 (and...). Figure 5 (Similarly), for example, it can see the position and orientation of the examination target 50 and the probe 60 on the examination target 50, which makes it easier for users to view the ultrasound image and the condition of the examination target and probe at the same time, making it easier for users to make a more accurate diagnosis.

[0158] In one embodiment, the first ultrasound image virtual image 23 and the second ultrasound image virtual image 33 can be overlapped. This way, for the user, the left second eye simultaneously views the virtual images located in the same position. Such virtual images are more similar to how a person views a real object with glasses, better conforming to human visual habits and avoiding any sense of incongruity. Of course, if necessary, the first ultrasound image virtual image 23 and the second ultrasound image virtual image 33 can also be non-overlapping.

[0159] The second optical component can be any suitable optical element or any suitable optical structure, as long as it can achieve the optical function described herein. For example, it can be a prism, a freeform mirror, an arrayed waveguide element, a diffractive waveguide element, or other suitable optical element, or a combination of these optical elements.

[0160] In one embodiment, the second opaque region 30 of the second lens 3 can be formed by a second light-shielding device (not shown) disposed on the outer or inner side of the second lens 3. This second light-shielding device can block light from the external environment from entering a portion of the second lens 3 (when the second light-shielding device is disposed on the outer side of the second lens 3) or block light from the external environment passing through a portion of the second lens 3 from continuing to enter the second eye (when the second light-shielding device is disposed on the inner side of the second lens 3), thereby forming the second opaque region 30 as described herein, while the remaining portion forms the aforementioned transparent region 31. The second light-shielding device can be any suitable type of light-shielding element, such as a light-shielding plate, a light-shielding film, a polarizing film, or other suitable elements.

[0161] In one embodiment, the second light-shielding device can be detachably mounted on the second lens 3 or the support frame 1. Thus, when needed, different second light-shielding devices (e.g., different shapes, sizes, light-shielding performance, opacity, etc.) can be replaced according to actual requirements to obtain a second opaque region 30 that meets different needs.

[0162] In one embodiment, the second light-shielding device can be rotatably connected to the support frame 1 or the second lens 3 via a second rotating joint (not shown), and can rotate between a shielded state that shields at least a portion of the second lens 3 to form the second opaque region 30, and an unshielded state that does not shield at least a portion of the second lens 3. Thus, when the user needs to view an ultrasound image, the second light-shielding device 26 can be rotated to the shielded state, thereby forming the second opaque region 30 on the second lens 3, allowing for a better view of the second ultrasound image virtual image 33 falling on the second opaque region 30. When the user needs to view the external real environment without viewing the ultrasound image, the second light-shielding device can be rotated to the unshielded state, giving the user a wider field of view to view the real environment.

[0163] Here, the second rotating joint can be any suitable rotating joint, such as a rotating joint formed by a shaft and a bearing, a rotating joint formed by a shaft and a shaft hole, etc. The rotation of the second light-shielding device via this second rotating joint can be manually driven by the user or driven by a drive device (e.g., a motor, etc.) provided in the head-mounted ultrasound image display device 100.

[0164] In one embodiment, the second light-shielding device can be movably connected to the support frame 1 or the second lens 3 via a second movable joint (not shown), and can move between a shielded state that shields at least a portion of the second lens 3 to form the second opaque region 30, and an unshielded state that does not shield at least a portion of the second lens 3. Thus, when the user needs to view an ultrasound image, the second light-shielding device can be moved to the shielded state, thereby forming the second opaque region 30 on the second lens 3, allowing for a better view of the second ultrasound image virtual image 33 falling on the second opaque region 30. When the user needs to view the external real environment without viewing the ultrasound image, the second light-shielding device can be moved to the unshielded state, giving the user a wider field of view to view the real environment.

[0165] In one embodiment, the second light-shielding device can be movably connected to the support frame 1 or the second lens 3 via a second sliding joint (not shown), and can move relative to the second lens 3. This allows for flexible adjustment of the position and / or size of the second light-shielding device relative to the second lens 3 as needed, thereby adjusting the position and / or size of the second opaque area 30 on the second lens 3.

[0166] For example, in one embodiment, the second light-shielding device can be moved as a whole relative to the second lens 3, so that the position of the second opaque area 30 on the second lens 3 can be easily adjusted.

[0167] Alternatively, in one embodiment, the second light-blocking device can move relative to the second lens 3 between a retracted state (e.g., a fully retracted or partially retracted state) and an extended state (e.g., a fully extended or partially extended state) (like a curtain or a camera shutter). In the fully retracted state, the second light-blocking device blocks a smaller area than in the fully extended state. The second light-blocking device can be adjusted to any state between the fully retracted and fully extended states. This allows for convenient adjustment of the size of the second opaque area 30 on the second lens 3.

[0168] Here, the second sliding pair in the aforementioned embodiments can be any suitable sliding pair, such as a sliding pair formed by a slide rail and a slider, a sliding pair formed by a slide rod and a slider, a sliding pair formed by a slider and a lead screw, a sliding pair formed by a guide rail and a guide groove, a sliding pair similar to a camera shutter structure, and so on. The movement of the second light-shielding device via this second sliding pair can be manually driven by the user or driven by a drive device (e.g., a motor, etc.) provided in the head-mounted ultrasonic image display device 100.

[0169] In one embodiment, the second light-shielding device may include a plurality of sub-light-shielding units (not shown) and a rotating or moving device (not shown). The rotating or moving device can drive the plurality of sub-light-shielding units to rotate or move between a first state and a second state. In the first state, the plurality of sub-light-shielding units are in close contact with each other, blocking light from passing through. In the second state, the plurality of sub-light-shielding units are spaced apart by a certain distance, allowing at least a portion of light to pass through (similar to a rotatable venetian blind structure or a camera shutter structure). This allows for convenient adjustment of the amount of light allowed to pass through the second light-shielding device or the size of the area allowed to pass through, thereby adjusting the opacity of the second light-shielding device or the size of the second opaque area 30. The rotating or moving device can be any suitable rotating or moving device, such as those found in venetian blind or camera shutter structures, and will not be described in detail here. The rotating or moving device can be manually driven by the user or driven by a driving device (e.g., a motor, etc.) provided in the head-mounted ultrasonic image display device 100.

[0170] In one embodiment, the second light-shielding device may include a rotating device (not shown). This rotating device can drive the second light-shielding device to rotate between a first state and a second state, wherein in the first state, the second light-shielding device blocks more light from passing through than in the second state. For example, the first state and the second state may correspond to a first angle and a second angle, respectively. At the first angle, compared to the second angle, the second light-shielding device may allow less light to pass through, such as by reflecting, absorbing, or scattering more incident light, etc. For example, in the first state, it may completely block or block a predetermined ratio of light from passing through, while in the second state, it may completely allow or allow a predetermined ratio of light to pass through, etc. This allows for convenient adjustment of the opacity of the first and second opaque regions. The rotating device here can be any suitable rotating device, which will not be detailed here. The rotating device can be manually driven by the user or driven by a driving device (e.g., a motor, etc.) provided in the head-mounted ultrasound image display device 100.

[0171] In one embodiment, the second light-shielding device can be a light-shielding film or a polarizing film, which can be fixedly bonded to the second lens 3, for example, bonded to a specific position on the inner or outer side of the second lens 3. Alternatively, the light-shielding film or polarizing film can be detachably bonded to the second lens 3. In this way, when needed, other light-shielding films or polarizing films can be replaced as required, thereby conveniently adjusting the position, size, and / or shape of the formed second opaque region 30.

[0172] In one embodiment, the second opaque region may be formed by an opaque layer (not shown) disposed inside the second lens 3. Alternatively, in one embodiment, the second opaque region may be made of an opaque material.

[0173] In the aforementioned embodiments, the first lens 2 and the second lens 3 are each equipped with their own display screens. However, in one embodiment, the first lens 2 and the second lens 3 may share a single display screen. In this embodiment, the head-mounted ultrasound image display device may include a support frame, a display screen, a first lens, a first optical component, a second lens, and a second optical component.

[0174] The support frame, similar to the embodiments described above, can be worn on the user's head. The display screen can be mounted directly on the support frame or indirectly via an intermediate element, and connect to an external device to display ultrasound images from that device.

[0175] The first lens and the second lens can be mounted directly or indirectly on the support frame through an intermediate element, and the first lens has a first opaque area and the second lens has a second opaque area.

[0176] The first optical component can be directly or indirectly mounted on the support frame through an intermediate element, and guides the light from the display screen into the user's first eye, so that the ultrasound image displayed on the display screen forms a first ultrasound image virtual image relative to the first eye through the first optical component, wherein the intersection area of ​​the first ultrasound image virtual image with the viewing angle area of ​​the first eye and the first lens is located in the first opaque area of ​​the first lens.

[0177] The second optical component can also be mounted directly or indirectly on the support frame through an intermediate element, and guide the light from the display screen into the user's second eye, so that the ultrasound image displayed on the display screen forms a second ultrasound image virtual image relative to the second eye through the second optical component, wherein the intersection area of ​​the second ultrasound image virtual image with the viewing angle area of ​​the second eye and the second lens is located in the second opaque area of ​​the second lens.

[0178] The first and second virtual ultrasound images may overlap. In other embodiments, the first and second virtual ultrasound images may not overlap.

[0179] In the foregoing embodiments, a first lens and a second lens are all included. However, in another embodiment, based on the foregoing embodiments, the first lens and the second lens can also be integrated, that is, a single lens, which is located in front of the first and second eyes when the user wears the head-mounted ultrasound image display device. A first opaque region and a second opaque region are formed on the lens. The formation of the first opaque region and the second opaque region can be the same as or similar to those in the foregoing embodiments, and will not be described in detail here. Apart from this integrated lens, other structures in this embodiment can be the same as or similar to the structures in the embodiments described above, and will not be described in detail here.

[0180] In a lens embodiment where the first and second lenses are integrated, the first and second opaque regions on the lens can also be integrated. In this embodiment, the lens may include a transparent region and an opaque region formed on the lens. An optical component (a first optical component or an optical component shared by the first and second eyes) can guide light from a display screen (a first display screen or a display screen shared by the first and second eyes) into the user's first eye, so that the ultrasound image displayed on the display screen (a first display screen or a display screen shared by the first and second eyes) forms a first ultrasound image virtual image relative to the first eye through the optical component (a first optical component or an optical component shared by the first and second eyes), wherein the intersection region of the first ultrasound image virtual image with the lens at the viewing angle region of the first eye is located in the opaque region of the lens. An optical component (a second optical component or an optical component shared by the first and second eyes) can guide light from a display screen (a second display screen or a display screen shared by the first and second eyes) into the user's second eye, so that the ultrasound image displayed on the display screen (a second display screen or a display screen shared by the first and second eyes) forms a second ultrasound image virtual image relative to the second eye through the optical component (a second optical component or an optical component shared by the first and second eyes), wherein the intersection area of ​​the second ultrasound image virtual image with the viewing angle area of ​​the second eye and the lens is located in the opaque area of ​​the lens.

[0181] All the foregoing embodiments include structures for both the first and second eyes. However, in one embodiment, the head-mounted ultrasound image display device can also be monocular, suitable for use with only one eye (either the first or second eye). In this embodiment, the head-mounted ultrasound image display device may include a support frame, a display screen, a lens, and optical components. The support frame can be worn on the user's head. The display screen can be mounted directly or indirectly on the support frame via an intermediate element, and connects to an external device to display ultrasound images from that external device. The lens can be mounted directly or indirectly on the support frame via an intermediate element, and an opaque area is formed on the lens.

[0182] The optical component can be mounted directly or indirectly on the support frame through an intermediate element, and guides the light from the display screen into the user's eyes, so that the ultrasound image displayed on the display screen forms an ultrasound image virtual image relative to the eyes through the optical component, wherein the intersection area of ​​the ultrasound image virtual image with the viewing angle area of ​​the eyes and the lens is located in the opaque area of ​​the lens.

[0183] In the aforementioned embodiments, the light from the display screen enters the human eye after passing through optical components. However, in other embodiments, the light from the display screen can also be projected onto an opaque area (e.g., a first opaque area and / or a second opaque area) on a lens (e.g., a first opaque area and / or a second opaque area) after passing through optical components, thereby projecting the ultrasound image displayed on the display screen onto the opaque area, allowing the human eye to directly observe the ultrasound image projected onto the opaque area of ​​the lens.

[0184] In this embodiment, the first optical component guides light from the first display screen (or a display screen shared by the first and second optical components) onto a first opaque area of ​​the first lens, thereby projecting the ultrasound image displayed on the first display screen (or the display screen shared by the first and second optical components) onto the first opaque area. The second optical component guides light from the second display screen (or the display screen shared by the first and second optical components) onto a second opaque area of ​​the second lens, thereby projecting the ultrasound image displayed on the second display screen (or the display screen shared by the first and second optical components) onto the second opaque area.

[0185] In this embodiment, the position and / or size of the first opaque region in the first lens may be the same as or correspond to the position and / or size of the second opaque region in the second lens, so that the ultrasound image projected onto the first opaque region observed by the first eye and the ultrasound image projected onto the second opaque region observed by the second eye visually overlap each other.

[0186] Similarly, in this embodiment, the first lens and the second lens can also be an integral lens, on which a first opaque region and a second opaque region are formed.

[0187] Other structures in this embodiment may be the same as or similar to those in the embodiments described above, and will not be repeated here.

[0188] In the foregoing embodiments, the optics from the display screen enter the user's eye through the first optical component and the second optical component, respectively. However, in one embodiment, a single optical component may be used. In this embodiment, the head-mounted ultrasound image display device may include a support frame, a first display screen, a first lens, a second display screen, a second lens, and an optical component. The optical component can guide light from the first display screen into the user's first eye, so that the ultrasound image displayed on the first display screen forms a first ultrasound image virtual image relative to the first eye through the optical component, wherein the intersection area of ​​the first ultrasound image virtual image relative to the viewing angle region of the first eye and the first lens is located in the first opaque region of the first lens; and guide light from the second display screen into the user's second eye, so that the ultrasound image displayed on the second display screen forms a second ultrasound image virtual image relative to the second eye through the optical component, wherein the intersection area of ​​the second ultrasound image virtual image relative to the viewing angle region of the second eye and the second lens is located in the second opaque region of the second lens.

[0189] In this embodiment, the first and second ultrasound virtual images may overlap (e.g., completely overlap). Alternatively, the first and second ultrasound virtual images may not overlap.

[0190] Other elements and structures in this embodiment may be the same as or similar to the corresponding elements and structures in the embodiments described above, and will not be repeated here.

[0191] Based on the embodiments using shared optical components described above, in one embodiment, a display screen can also be shared. The optical component guides light from the display screen into the user's first and second eyes. In this embodiment, the head-mounted ultrasound image display device may include a support frame, a display screen, a first lens, a second lens, and the optical component. The display screen is mounted directly or indirectly on the support frame via an intermediate element and is connected to an external device to display ultrasound images from that external device.
