Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a heterogeneous probe for multimodal high-resolution imaging and its usage method. Background Technology

[0002] Existing clinical imaging technologies are mainly divided into photoacoustic imaging and ultrasound imaging.

[0003] Photoacoustic imaging uses pulsed light to excite chromophores (such as hemoglobin and melanin) in tissues, causing them to absorb photons of specific wavelengths, triggering transient expansion and generating broadband ultrasound. The ultrasound signal is captured by an ultrasound transducer in the imaging probe, and the signal is reconstructed to generate a medical image. This process of imaging ultrasound signals generated by light excitation is called photoacoustic imaging. Photoacoustic imaging enables functional examination of the examined area, achieving high-resolution optical contrast imaging at depths exceeding 10 mm, and is particularly suitable for imaging deep tissues such as tumors and vascular structures.

[0004] Ultrasound imaging, such as B-mode ultrasound, can perform structural examinations of the area to be examined. This involves scanning the human body with an ultrasound beam and receiving and processing the ultrasound signals reflected from the area to be examined through an ultrasound transducer in the imaging probe to obtain images of the internal organs.

[0005] If both photoacoustic imaging and ultrasound imaging are used to examine the same area, the accuracy of the examination results can be improved. However, because the ultrasound transducers used in photoacoustic imaging and ultrasound imaging are not interchangeable, current examinations of structural and functional aspects must be performed separately. This requires doctors to operate both machines sequentially, which not only increases the space required for installation of photoacoustic imaging and ultrasound imaging, but also makes the two examinations time-consuming and labor-intensive, increasing the complexity of the examination.

[0006] Therefore, there is an urgent need for an imaging probe that can be adapted to photoacoustic imaging and ultrasound imaging, so that photoacoustic imaging and ultrasound imaging can be integrated into one unit, so that structural and functional examinations of the examination site can be performed simultaneously in a single examination. Summary of the Invention

[0007] In view of this, the present invention provides a heterogeneous probe and method of use for multimodal high-resolution imaging, which can improve the accuracy of examination results when both photoacoustic imaging and ultrasound imaging are used to examine the site. However, because the ultrasound transducers for photoacoustic imaging and ultrasound imaging are not interchangeable, existing examinations of structural and functional aspects must be performed separately, i.e., photoacoustic imaging and ultrasound imaging must be performed separately. In this process, doctors need to operate two machines sequentially, which not only increases the installation space required for photoacoustic imaging and ultrasound imaging, but also makes the two examinations time-consuming and labor-intensive, increasing the complexity of the examination.

[0008] In a first aspect, the present invention provides a heterogeneous probe for multimodal high-resolution imaging, comprising: The first transducer array includes multiple first transducer elements arranged linearly. The first transducer array is located on one side of the part to be inspected and is used to emit at least two angle plane waves to the part to be inspected and then receive the ultrasonic signal reflected by the part to be inspected. A second transducer array is disposed on one side of the first transducer array and connected to the first transducer array. The second transducer array includes a plurality of second transducer array elements, which are arranged in a first arc-shaped array. The surface formed by the first arc-shaped array is designated as a first arc-shaped surface. The plurality of second transducer array elements are used to cooperate with a conduction unit. When the conduction unit emits light to the part to be inspected, the part to be inspected emits an ultrasonic signal. The ultrasonic signal is received by at least the second transducer array and the first transducer array. The second transducer array is also used to receive the ultrasonic signal reflected by the part to be inspected after the first transducer array emits at least two angle plane waves to the part to be inspected. A third transducer array is disposed on the other side of the first transducer array and connected to the first transducer array. The third transducer array includes multiple third transducer elements, which are arranged in a second arc-shaped array. The surface formed by the second arc-shaped array is a second arc-shaped surface. The multiple third transducer elements are used to cooperate with the conduction unit. After the conduction unit emits light to the part to be inspected, the third transducer array can collect and process the ultrasonic signal emitted by the part to be inspected. The third transducer array is also used to receive the ultrasonic signal reflected by the part to be inspected after the first transducer array emits at least two angle plane waves to the part to be inspected. The first transducer array, the second transducer array, and the third transducer array are arranged to form a placement area, which is used to accommodate the part to be inspected.

[0009] Beneficial effects: By setting up a first transducer array, a second transducer array, and a third transducer array, and limiting the first transducer array to be a linear arrangement of multiple first transducer array elements, the second transducer array to be a first arc-shaped array formed by arranging multiple second transducer array elements, and the third transducer array to be a second arc-shaped array formed by arranging multiple third transducer array elements.

[0010] Based on this, when the part to be inspected is placed within the area enclosed by the first transducer array, the second transducer array, and the third transducer array, a plane wave can be emitted to the part to be inspected through the linear first transducer array. Then, the part to be inspected reflects the plane wave as an ultrasonic signal back to the first transducer array, the second transducer array, and the third transducer array, so that the heterogeneous probe used for multimodal high-resolution imaging can perform ultrasonic imaging on the part to be inspected. When the peripheral device's transmission unit emits light towards the area to be examined, the area generates an ultrasound signal, which is then transmitted to the first, second, and third transducer arrays for processing. By integrating these arrays, the field of view of photoacoustic imaging can be improved. This allows the heterogeneous probe used for multimodal high-resolution imaging to simultaneously perform photoacoustic and ultrasound imaging on the area to be examined, eliminating the need for doctors to operate two separate machines sequentially. This improves imaging efficiency and simplifies the operation of the heterogeneous probe used for multimodal high-resolution imaging.

[0011] In one alternative embodiment, the second transducer array and the third transducer array are arranged symmetrically with respect to the central axis of the first transducer array. And / or, the second transducer array element and / or the third transducer array element are 32; And / or, the first transducer array has 64 elements; And / or, the center of the first arcuate surface coincides with the center of the second arcuate surface; And / or, the radius of the first arcuate surface and / or the second arcuate surface is 40 mm.

[0012] Beneficial effects: By symmetrically arranging the second and third transducer arrays relative to the central axis of the first transducer array, with the radii of the first and second arc-shaped surfaces both being 40 mm, and the centers of the first and second arc-shaped surfaces coinciding, the field of view and lateral resolution of photoacoustic imaging can be improved. This results in a wider imaging area for the heterogeneous probe used for multimodal high-resolution imaging, thereby enhancing the imaging accuracy of the heterogeneous probe.

[0013] In one optional embodiment, the line connecting the end of the second transducer array away from the first transducer array to the center of the first arc-shaped surface is the first line, and the line connecting the end of the third transducer array away from the first transducer array to the center of the first arc-shaped surface is the second line, and the angle between the first line and the second line is 145°.

[0014] Beneficial effects: By defining the first connecting line as the line between the end of the second transducer array furthest from the first transducer array and the center of the first arc-shaped surface, and the second connecting line as the line between the end of the third transducer array furthest from the first transducer array and the center of the first arc-shaped surface, the angle between the first and second connecting lines is 145°. Based on this, the imaging field of view of the heterogeneous probe used for multimodal high-resolution imaging can be improved, thereby achieving the technical effect of improving the imaging accuracy of the heterogeneous probe used for multimodal high-resolution imaging.

[0015] In one alternative implementation, the second transducer array, the first transducer array, and the third transducer array are connected in sequence to form an inverted "U" shape, and the top of the inverted "U" shape is a plane.

[0016] In one alternative implementation, the heterogeneous probe for multimodal high-resolution imaging includes: A light-emitting unit, used to emit light, wherein the light is laser light; The conductive unit includes multiple conductive structures, one end of each conductive structure is connected to the light-emitting unit, and the light-emitting surface of each conductive structure is arranged facing the placement area to conduct the light emitted by the light-emitting unit to the part to be inspected.

[0017] In one optional implementation, at least two conductive units are provided; And / or, the conducting unit is connected to the first transducer array.

[0018] Beneficial effects: By limiting the number of transmission units to at least two, uniform illumination can be provided to the area to be examined, avoiding uneven brightness that could affect image quality. This achieves the technical effect of improving the imaging accuracy of heterogeneous probes used for multimodal high-resolution imaging.

[0019] In one optional implementation, the heterogeneous probe for multimodal high-resolution imaging includes: A connection structure is disposed between the conductive unit and the first transducer array, with one end of the connection structure connected to the first transducer array and the other end connected to the conductive unit; And / or, there are two conductive units, which are symmetrically arranged with respect to the central axis of the first transducer array.

[0020] Beneficial effects: By setting up a connection structure, the number of connection points between the first transducer array and the conduction unit can be increased, thereby achieving the technical effect of improving the connection reliability between the conduction unit and the first transducer array.

[0021] By defining two transmission units, uniform illumination can be provided to the area to be inspected, avoiding uneven lighting that could affect image quality. This achieves the technical effect of improving the imaging accuracy of heterogeneous probes used for multimodal high-resolution imaging.

[0022] In one optional embodiment, the connection structure is a connecting frame, the connecting edge of the connecting frame and the conducting unit are arranged parallel to the conducting unit, and are arranged at an angle relative to the central axis of the first transducer array; And / or, the connection structure is detachably connected to the conductive unit, and / or the connection structure is detachably connected to the first transducer array.

[0023] Beneficial effects: By defining the connection structure as a connecting frame, with the connecting edge of the connecting frame and the transmission unit being parallel to the transmission unit and at an angle relative to the central axis of the first transducer array, i.e., the connection structure is an inclined "L" shape, with the right end of the "L" shape connected to the first transducer array and the left side of the "L" shape being fully fitted to the transmission unit, the number of connection points between the first transducer array and the transmission unit can be increased, thereby achieving the technical effect of improving the connection reliability between the transmission unit and the first transducer array; By defining a detachable connection between the connecting structure and the conductive unit, and between the connecting structure and the first transducer array, the technical effect of improving the ease of maintenance and replacement between the connecting structure and the conductive unit, and between the connecting structure and the first transducer array, can be achieved.

[0024] In one optional implementation, the heterogeneous probe for multimodal high-resolution imaging includes: An image processing device is communicatively connected to the first transducer array, the second transducer array, and the third transducer array. The image processing device is used to process the ultrasonic signals transmitted by the first transducer array, the second transducer array, and the third transducer array, and generate images. And / or, a control device, communicatively connected to the first transducer array, the second transducer array, the third transducer array, the conductive unit, and the light-emitting unit, is used to control the on / off switching of light emitted by the light-emitting unit and the conductive unit, the on / off switching of plane wave emitted by the first transducer array, and the on / off switching of ultrasonic signal received by the first transducer array, the second transducer array, and the third transducer array.

[0025] Beneficial effects: When the heterogeneous probe used for multimodal high-resolution imaging is only in photoacoustic mode, the control device controls the emitting unit and the conducting unit to emit light, and enables the first transducer array, the second transducer array, and the third transducer array to receive ultrasonic signals. The first transducer array is only used to receive ultrasonic signals and does not emit plane waves. The emitting unit and the conducting unit work together to emit light towards the area to be examined. Because the area to be examined has materials with strong optical absorption properties, it absorbs light energy and causes thermal expansion, thereby generating ultrasonic signals that propagate outward. The first transducer array, the second transducer array, and the third transducer array receive the ultrasonic signals and transmit them to the image processing device. After analog-to-digital conversion by the image processing device, beamforming and image processing are performed to finally generate a photoacoustic image. The generated multispectral photoacoustic image can be used to calculate vascular distribution, hemoglobin concentration distribution, and blood oxygenation protection level.

[0026] When the imaging system is in ultrasound mode only, the control device enables the first, second, and third transducer arrays to receive ultrasound signals and controls the first transducer array to emit plane waves at three angles toward the area to be examined, namely the first ultrasound beam, the second ultrasound beam, and the third ultrasound beam. The ultrasound signals reflected back from the area to be examined can be received by the first, second, and third transducer arrays and transmitted to the image processing device. After analog-to-digital conversion by the image processing device, beamforming and image processing are performed to finally generate an ultrasound image, i.e., an anatomical structure image.

[0027] When the imaging device is in photoacoustic and ultrasonic dual-modal imaging mode, the control device controls the light-emitting unit and the conduction unit to emit light, and enables the first transducer array, the second transducer array and the third transducer array to receive ultrasonic signals. At the same time, the control device controls the first transducer array to emit plane waves at three angles toward the part to be inspected. Due to the natural spatial registration, the generated photoacoustic image and ultrasonic image can be seamlessly fused to generate a structural and functional image.

[0028] Secondly, the present invention also provides a method for using a heterogeneous probe for multimodal high-resolution imaging, which is the above-mentioned method for using a heterogeneous probe for multimodal high-resolution imaging, the method comprising: Place the area to be inspected within the designated area; Obtain the mode of the heterogeneous probe used for multimodal high-resolution imaging; If the heterogeneous probe used for multimodal high-resolution imaging is in ultrasonic mode, the first transducer array emits plane waves at at least two angles toward the part to be inspected. The first transducer array, the second transducer array, and the third transducer array receive the ultrasonic signals reflected from the part to be inspected; After generating an image based on the ultrasound signal, the ultrasound mode ends. If the heterogeneous probe used for multimodal resolution imaging is in photoacoustic mode, the transmission unit emits light towards the area to be inspected; The first transducer array, the second transducer array, and the third transducer array receive the ultrasonic signals emitted by the part to be inspected; After generating an image based on the ultrasound signal, the photoacoustic mode ends. If the heterogeneous probe used for multimodal resolution imaging is in photoacoustic-ultrasound dual-modal imaging mode, the ultrasonic mode and the photoacoustic mode work alternately. The photoacoustic-ultrasound dual-modal imaging mode ends after at least one image is generated based on the ultrasound signal. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0034] According to an embodiment of the present invention, in one aspect, a heterogeneous probe for multimodal high-resolution imaging is provided, comprising: The first transducer array 101 includes a plurality of first transducer elements arranged linearly. The first transducer array 101 is located on one side of the part to be inspected 10 and is used to transmit at least two angle plane waves to the part to be inspected 10 and receive the ultrasonic signal reflected by the part to be inspected 10. The second transducer array 102 is disposed on one side of the first transducer array 101 and connected to the first transducer array 101. The second transducer array 102 includes a plurality of second transducer elements, which are arranged in a first arc array. The surface formed by the first arc array is designated as the first arc surface 2. The plurality of second transducer elements are used to cooperate with the conduction unit 7. When the conduction unit 7 emits light 11 to the part to be inspected 10, the part to be inspected 10 emits an ultrasonic signal. The ultrasonic signal is received by at least the second transducer array 102 and / or the first transducer array 101. The second transducer array 102 is also used to receive the ultrasonic signal reflected by the part to be inspected 10 after the first transducer array 101 emits at least two angle plane waves to the part to be inspected 10. The third transducer array 103 is located on the other side of the first transducer array 101 and connected to the first transducer array 101. The third transducer array 103 includes a plurality of third transducer elements, which are arranged in a second arc array. The surface formed by the second arc array is designated as the second arc surface 3. The plurality of third transducer elements are used to cooperate with the conduction unit 7. After the conduction unit 7 emits light 11 to the part to be inspected 10, the third transducer array 103 can collect and process the ultrasonic signal emitted by the part to be inspected 10. The third transducer array 103 is also used to receive the ultrasonic signal reflected by the part to be inspected 10 after the first transducer array 101 emits at least two angle plane waves to the part to be inspected 10. A placement area is formed between the first transducer array 101, the second transducer array 102, and the third transducer array 103, and the placement area is used to accommodate the part 10 to be inspected.

[0035] In the heterogeneous probe for multimodal high-resolution imaging in this embodiment, a first transducer array 101, a second transducer array 102, and a third transducer array 103 are connected. The first transducer array 101 is defined as a linear arrangement of multiple first transducer elements, the second transducer array 102 is a first arc-shaped array formed by arranging multiple second transducer elements, and the third transducer array 103 is a second arc-shaped array formed by arranging multiple third transducer elements.

[0036] Based on this, when the part to be inspected 10 is placed within the placement area enclosed between the first transducer array 101, the second transducer array 102, and the third transducer array 103, a plane wave can be emitted to the part to be inspected 10 through the linear first transducer array 101. Then, the part to be inspected 10 reflects the plane wave in the form of an ultrasonic signal to the first transducer array 101, the second transducer array 102, and the third transducer array 103, so that the heterogeneous probe 1 for multimodal high-resolution imaging can perform ultrasonic imaging on the part to be inspected 10. When the peripheral transmission unit 7 emits light 11 towards the area to be examined 10, the area to be examined 10 generates an ultrasound signal and transmits the ultrasound signal to the first transducer array 101, the second transducer array 102, and the third transducer array 103, so that the first transducer array 101, the second transducer array 102, and the third transducer array 103 can process the ultrasound signal. By integrating the first transducer array 101, the second transducer array 102, and the third transducer array 103 into one unit, the field of view of photoacoustic imaging can be improved. This enables the heterogeneous probe 1 for multimodal high-resolution imaging to simultaneously perform photoacoustic imaging and ultrasound imaging on the area to be examined 10, eliminating the need for doctors to operate two machines sequentially in related technologies. This achieves the technical effect of improving imaging efficiency and simplifying the operation of the heterogeneous probe 1 for multimodal high-resolution imaging.

[0037] In this embodiment, the ultrasonic signal reflected by the part to be inspected 10 is sent to the first transducer array 101, the second transducer array 102, and the third transducer array 103. That is, the first transducer array 101, the second transducer array 102, and the third transducer array 103 simultaneously receive the ultrasonic signal reflected by the part to be inspected 10, so as to collect the ultrasonic signal reflected by the part to be inspected 10 simultaneously through the first transducer array 101, the second transducer array 102, and the third transducer array 103.

[0038] Of course, in other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, it is also possible that only the first transducer array 101 collects the ultrasonic signals reflected from the area to be examined 10, or only the second transducer array 102 collects the ultrasonic signals reflected from the area to be examined 10, or only the third transducer array 103 collects the ultrasonic signals reflected from the area to be examined 10, or any two of the first transducer array 101, the second transducer array 102, and the third transducer array 103 collect the ultrasonic signals reflected from the area to be examined 10. Compared with other embodiments, in this embodiment, either only the second transducer array 102 collects the ultrasonic signals reflected from the area to be examined 10 simultaneously, which can avoid omissions in the collection of ultrasonic signals reflected from the area to be examined 10, thereby improving the comprehensiveness of the heterogeneous probe 1 used for multimodal high-resolution imaging in collecting reflected ultrasonic signals, and thus achieving the technical effect of improving the imaging accuracy of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0039] In addition, when the transmission unit 7 emits light 11 to the part to be inspected 10, the part to be inspected 10 emits an ultrasonic signal. This process is based on the principle of photoacoustic imaging, which is a mature technology and will not be elaborated further.

[0040] In addition, plane waves are a type of ultrasonic wave. A plane wave has parallel plane wavefronts, and ultrasonic waves with parallel planar wavefronts are plane waves. A plane wave can be viewed as an infinitely large planar sound source propagating in a simple harmonic oscillation within an isotropic elastic medium. The wavefront of a plane wave is parallel to the sound source plane and has good directionality when propagating in a straight line. Without absorption, the sound pressure does not change with distance. Ideal plane waves do not exist, but if the cross-sectional size of the sound source is much larger than the wavelength it produces, the sound wave emitted by the source can be approximated as a plane wave pointing in one direction. If attenuation by the medium is neglected, the sound pressure of a plane wave does not change with the distance from the sound source.

[0041] Furthermore, in this embodiment, the site 10 to be examined is biological tissue. Of course, in other embodiments, the type of site 10 to be examined may be adjusted depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0042] In addition, combined Figure 1 As shown, in this embodiment, the second transducer array 102, the first transducer array 101, and the third transducer array 103 are connected sequentially to form an inverted "U" shape, with the top of the inverted "U" shape being a plane. That is, one end of the first transducer array 101 along its length is connected to one end of the first arc-shaped surface 2, and the other end of the first transducer array 101 along its length is connected to one end of the second arc-shaped surface 3.

[0043] Of course, in other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, the positions of the first transducer array 101, the second transducer array 102, and the third transducer array 103 are adjusted. Simultaneously, the shape of the combination of the first transducer array 101, the second transducer array 102, and the third transducer array 103 is adjusted; for example, the first transducer array 101, the second transducer array 102, and the third transducer array 103 form an "O" shape with a flat top. Compared to other embodiments, the heterogeneous probe 1 used for multimodal high-resolution imaging in this embodiment has the advantages of a simple structure and small footprint, thereby improving the structural simplicity of the heterogeneous probe 1 used for multimodal high-resolution imaging and reducing space limitations, thus achieving the technical effect of improving the ease of use of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0044] In addition, combined Figure 1 As shown, the second transducer array 102 and the third transducer array 103 are symmetrically arranged with respect to the central axis 9 of the first transducer array 101, wherein the central axis 9 is parallel to... Figure 1 The vertical direction shown, and passing through Figure 1 The line segment at the midpoint of the horizontal dimension of the first transducer array 101 is shown. Simultaneously, the radius R of the first arc surface 2 and the second arc surface 3 is 40mm, and the center of the first arc surface 2 coincides with the center of the second arc surface 3, with the coinciding center being O. Based on this, the field of view of photoacoustic imaging can be improved, and the lateral resolution of photoacoustic imaging can be enhanced, so that the imaging area of ​​the heterogeneous probe 1 used for multimodal high-resolution imaging is wider, thereby achieving the technical effect of expanding the imaging accuracy of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0045] Of course, in other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, the second transducer array 102 and the third transducer array 103 may not be symmetrically arranged relative to the central axis 9 of the first transducer array 101. Alternatively, the radii of the first arcuate surface 2 and the second arcuate surface 3 may be adjusted. Furthermore, the center of the first arcuate surface 2 may not coincide with the center of the second arcuate surface 3; all of these are within the scope of protection of this invention.

[0046] In addition, in this embodiment, there are 32 second and third transducer array elements and 64 first transducer array elements.

[0047] Of course, in other embodiments, the number of the first transducer array 101, the second transducer array 102, and the third transducer array 103 may be adjusted depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0048] In other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, the following are all within the protection scope of this invention: the second transducer array 102 and the third transducer array 103 are symmetrically arranged with respect to the central axis 9 of the first transducer array 101; the second transducer array 102 and / or the third transducer array 103 consists of 32 units; the first transducer array 101 consists of 64 units; the center of the first arc surface 2 coincides with the center of the second arc surface 3; and the radius of the first arc surface 2 and / or the second arc surface 3 is 40 mm.

[0049] In addition, combined Figure 1 As shown, in this embodiment, the line connecting the end of the second transducer array 102 furthest from the first transducer array 101 to the center of the first arc-shaped surface 2 is the first connecting line; the line connecting the end of the third transducer array 103 furthest from the first transducer array 101 to the center of the first arc-shaped surface 2 is the second connecting line; the angle between the first and second connecting lines is 145°. Based on this, the imaging field of view of the heterogeneous probe 1 used for multimodal high-resolution imaging can be improved, thereby achieving the technical effect of improving the imaging accuracy of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0050] Of course, in other embodiments, the angle between the first and second connecting lines is adjusted depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0051] In addition, combined Figure 4 As shown, the ultrasonic beam emitted by the first transducer array 101 includes: The first ultrasonic beam 4 has an angle of 4° with the central axis 9; The second ultrasonic beam 5 has an angle of 4° with the central axis 9. The point where the extension of the second ultrasonic beam 5 intersects with the extension of the first ultrasonic beam 4 is set as the intersection point. A line parallel to the central axis 9 is drawn through the intersection point. The first ultrasonic beam 4 and the second ultrasonic beam 5 are symmetrically arranged with respect to the line parallel to the central axis 9.

[0052] The third ultrasonic beam 6 is set parallel to the central axis 9.

[0053] Based on this, the angle value of the plane wave emitted by the first transducer array 101 can be increased, and the imaging angle of the part to be inspected 10 can be increased, thereby achieving the technical effect of improving the imaging accuracy of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0054] Of course, in other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, it may be limited to the ultrasonic beam emitted by the first transducer array 101 including the first ultrasonic beam 4 and the second ultrasonic beam 5, or it may be limited to the ultrasonic beam emitted by the first transducer including the third ultrasonic beam 6, both of which are within the scope of protection of this invention. Alternatively, the number of ultrasonic beams may be adjusted.

[0055] In other embodiments, the angles of the first ultrasonic beam 4 and the second ultrasonic beam 5 are adjusted according to the different designs of the heterogeneous probe 1 used for multimodal high-resolution imaging. Compared with other embodiments, this embodiment, by limiting the angles of the first ultrasonic beam 4 and the second ultrasonic beam 5, avoids the angles of the first ultrasonic beam 4 and the second ultrasonic beam 5 being too small, which would affect the detection range of imaging, and at the same time avoids the angles of the first ultrasonic beam 4 and the second ultrasonic beam 5 being too large, which would affect the reception quality of ultrasonic signals, thereby achieving the technical effect of improving the imaging quality of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0056] In other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, only the line connecting the center of the first arc surface 2 and the side of the second transducer array 102 away from the first transducer array 101 is limited to having an angle of 145 degrees with the line connecting the center of the first arc surface 2 and the side of the third transducer array 103 away from the first transducer array 101, or only the ultrasonic beam emitted by the first transducer array 101 is limited to include the first ultrasonic beam 4 and the second ultrasonic beam 5.

[0057] Furthermore, in this embodiment, the heterogeneous probe 1 for multimodal high-resolution imaging includes: The light-emitting unit is used to emit light 11, which is a laser light. The conduction unit 7 includes multiple conduction structures. Each conduction structure has one end connected to the light-emitting unit and the light-emitting surface of each conduction structure is arranged facing the placement area to conduct the light 11 emitted by the light-emitting unit to the part 10 to be inspected.

[0058] By setting up the transmission unit 7, the transmission unit 7 emits light to the area to be inspected 10, enabling the heterogeneous probe 1 for multimodal high-resolution imaging to perform photoacoustic imaging on the area to be inspected 10. Simultaneously, by limiting the orientation of the light-emitting surface of the transmission unit 7 towards the placement area, i.e., by setting the transmission unit 7 at an angle to the first transducer array 101, the light rays 11 emitted by the transmission unit 7 can be uniformly distributed on the area to be inspected 10, increasing the illumination brightness of the area to be inspected 10, thereby achieving the technical effect of improving the imaging accuracy of the heterogeneous probe 1 for multimodal high-resolution imaging.

[0059] The specific location of the light-emitting unit is not limited; it can be connected to the first transducer array 101, the second transducer array 102, or the third transducer array 103, or it can be placed at a desired location. The light-emitting unit is a laser, and the transmission structure is an optical fiber. The transmission unit 7 is an optical fiber bundle formed by multiple transmission structures. This embodiment does not limit the wavelength of the light emitted by the light-emitting unit 11. As long as the wavelength can achieve an imaging field of view of not less than 20mm × 10mm, a spatial resolution of not less than 500um, and an imaging depth of not less than 30mm, it is within the protection scope of this invention.

[0060] Of course, in other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, the type of light emitted by the light-emitting unit 11 is adjusted, that is, the type of light-emitting unit is adjusted, and the values ​​of imaging field of view, spatial resolution and imaging depth are adjusted.

[0061] In addition, combined Figure 1 As shown, in this embodiment, two transmission units 7 are provided. Based on this, uniform illumination can be provided to the area 10 to be inspected, avoiding uneven brightness that would affect the imaging quality, thereby achieving the technical effect of improving the imaging accuracy of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0062] One of the conducting units 7 is located in Figure 2 On one side of the first transducer array 101 along the Y-axis, another conducting unit 7 is located... Figure 2 The other side of the first transducer array 101 along the Y-axis.

[0063] Of course, in other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, the number of conduction units 7 may be adjusted to one or three, all of which are within the protection scope of this invention.

[0064] In other embodiments, the position of the conduction unit 7 may be adjusted according to the different designs of the heterogeneous probe 1 used for multimodal high-resolution imaging. As long as the conduction unit 7 is oriented toward the placement area, it is within the protection scope of the present invention.

[0065] Furthermore, in this embodiment, the conduction unit 7 is connected to the first transducer array 101. Based on this, the integrity of the heterogeneous probe 1 used for multimodal high-resolution imaging can be increased, thereby achieving the technical effect of improving the ease of use of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0066] Among them, combined Figure 2 As shown, the heterogeneous probe 1 for multimodal high-resolution imaging includes: The connection structure 8 is located between the conduction unit 7 and the first transducer array 101. One end of the connection structure 8 is connected to the first transducer array 101, and the other end is connected to the conduction unit 7.

[0067] By setting the connection structure 8, the number of connection points between the first transducer array 101 and the conduction unit 7 can be increased, thereby achieving the technical effect of improving the connection reliability between the conduction unit 7 and the first transducer array 101.

[0068] Preferably, the connecting structure 8 is a connecting frame, and the connecting edge of the connecting frame and the conducting unit 7 is arranged parallel to the conducting unit 7. That is, the connecting surface of the connecting frame to the conducting unit 7 is parallel to the connecting surface of the conducting unit 7 to the connecting frame, and is set at an angle relative to the central axis 9 of the first transducer array 101. That is, the connecting structure 8 is an inclined "L" shape, the right end of the "L" shape is connected to the first transducer array 101, and the left side of the "L" shape is completely fitted to the conducting unit 7. This can increase the number of connection points between the first transducer array 101 and the conducting unit 7, thereby achieving the technical effect of improving the connection reliability between the conducting unit 7 and the first transducer array 101.

[0069] Furthermore, the connection structure 8 is detachably connected to the conduction unit 7, and also to the first transducer array 101. Based on this, the ease of maintenance and replacement between the connection structure 8 and the conduction unit 7, and between the connection structure 8 and the first transducer array 101, can be improved.

[0070] The connecting structure 8 and the conducting unit 7, as well as the connecting structure 8 and the first transducer array 101, are connected by threads. For example, both the connecting structure 8 and the conducting unit 7 have communicating first threaded holes, and a first bolt is threadedly connected to both the connecting structure 8 and the conducting unit 7. Both the connecting structure 8 and the first transducer array 101 have communicating second threaded holes, and a second bolt is threadedly connected to both the second threaded holes of the connecting structure 8 and the first transducer array 101, thus achieving a detachable connection between the connecting structure 8 and the conducting unit 7, and between the connecting structure 8 and the first transducer array 101.

[0071] Of course, in other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, the connection methods between the connecting structure 8 and the conduction unit 7, and between the connecting structure 8 and the first transducer array 101, can be adjusted. For example, a detachable connection can be achieved through snap-fit, or the connecting structure 8 and the conduction unit 7, and the connecting structure 8 and the first transducer array 101, can be fixedly connected. Both snap-fit ​​and fixed connections are mature technologies and will not be further limited here.

[0072] As an alternative implementation, the connection structure 8 may be defined as one or a combination of multiple structures, such as a connection frame, a detachable connection between the connection structure 8 and the conduction unit 7, and a detachable connection between the connection structure 8 and the first transducer array 101. All of these are within the scope of protection of this invention.

[0073] In other embodiments, the structure of the connecting structure 8 may be adjusted according to the different designs of the heterogeneous probe 1 used for multimodal high-resolution imaging. For example, the connecting structure 8 may be a plate-like structure, all of which are within the protection scope of this invention.

[0074] As an alternative implementation, the heterogeneous probe 1 for multimodal high-resolution imaging may not include the connection structure 8, and the conduction unit 7 may be directly connected to the first transducer array 101.

[0075] In other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, it is only limited to having at least two transmission units 7, or only limited to the transmission unit 7 being connected to the first transducer array 101, all of which are within the protection scope of the present invention.

[0076] Furthermore, in this embodiment, the connecting structure 8 is made of a high-strength and lightweight material, such as PLA (Polylacticacid fiber). Based on this, the structural stability and durability of the heterogeneous probe 1 used for multimodal high-resolution imaging can be improved. While ensuring the structural stability of the heterogeneous probe 1 used for multimodal high-resolution imaging, the overall weight of the heterogeneous probe 1 used for multimodal high-resolution imaging can be reduced, thereby achieving the technical effect of improving the portability of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0077] Among them, the connecting structure 8 can be printed using 3D (Three Dimensional) printing technology.

[0078] Of course, in other embodiments, the material and manufacturing method of the connection structure 8 may be adjusted depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0079] In addition, combined Figure 2 As shown, in this embodiment, two transmission units 7 are symmetrically arranged with respect to the central axis 9 of the first transducer array 101. A straight line is drawn on the transmission unit 7, passing through the center of the transmission unit 7 along the X-axis and the center of its length along the Y-axis, and parallel to the transmission unit 7. This straight line can pass through the central axis 9 of the first transducer array 101 and form an intersection point. A perpendicular line is drawn from this intersection point to the surface of the first transducer, with a length of 31 mm. Based on this, the uniformity of light 11 at both ends of the first transducer can be improved, that is, the first transducer at... Figure 1 The left end shown is in relation to the first transducer. Figure 1 The right end shown has equal brightness, thus achieving the technical effect of improving the imaging quality of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0080] Of course, in other embodiments, depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging, the two transmission units 7 can be asymmetrically arranged relative to the central axis 9 of the first transducer array 101. Alternatively, a straight line can be drawn on the transmission unit 7, passing through the center of the transmission unit 7 along the X-axis and the center of its length along the Y-axis, and parallel to the transmission unit 7, without crossing the central axis 9 of the first transducer array 101. Alternatively, the length of the vertical line can be adjusted.

[0081] In other embodiments, depending on the design of the heterogeneous probe 1 for multimodal high-resolution imaging, the heterogeneous probe 1 for multimodal high-resolution imaging is limited to include a connecting structure 8 and two conducting units 7. One of the two conducting units 7 is symmetrically arranged with respect to the central axis 9 of the first transducer array 101, or any combination of two structures, is within the protection scope of this invention.

[0082] In addition, in this embodiment, the heterogeneous probe 1 for multimodal high-resolution imaging includes: The image processing device is communicatively connected to the first transducer array 101, the second transducer array 102, and the third transducer array 103. The image processing device processes the ultrasonic signals transmitted from the first transducer array 101, the second transducer array 102, and the third transducer array 103 and generates images. The communication connection is a mature technology and will not be elaborated upon here. Both wired and wireless communication are within the scope of this invention.

[0083] In this embodiment, the image processing device is an application-specific integrated circuit (ASIC). Of course, in other embodiments, the type of image processing device may be adjusted depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0084] As an alternative implementation, the heterogeneous probe 1 for multimodal high-resolution imaging may not include an image processing device, and the first transducer array 101, the second transducer array 102, and the third transducer array 103 may all be directly connected to a host computer. The host computer is a computer. Of course, in other embodiments, the type of host computer may be adjusted depending on the design of the heterogeneous probe 1 for multimodal high-resolution imaging.

[0085] Furthermore, in this embodiment, the heterogeneous probe 1 for multimodal high-resolution imaging includes: The control device is communicatively connected to the first transducer array 101, the second transducer array 102, the third transducer array 103, the conduction unit 7, and the light-emitting unit. It is used to control the on / off state of the light-emitting unit and the conduction unit 7 emitting light beams 11, the on / off state of the first transducer array 101 emitting plane waves, and the on / off state of the first transducer array 101, the second transducer array 102, and the third transducer array 103 receiving ultrasonic signals. This allows the heterogeneous probe 1 used for multimodal high-resolution imaging to have three operating modes: when only the conduction unit 7 emits light beams 11 to the part to be inspected 10, the imaging device is in photoacoustic mode; when only the first transducer array 101 emits plane waves to the part to be inspected 10, the imaging device is in ultrasonic mode; and when the conduction unit 7 emits light beams 11 to the part to be inspected 10 while the first transducer array 101 emits plane waves, photoacoustic imaging and ultrasonic imaging alternate, which is a photoacoustic-ultrasonic dual-modal imaging mode.

[0086] In this embodiment, the control device is a programmable logic controller.

[0087] Specifically, when the heterogeneous probe 1 used for multimodal high-resolution imaging is only in photoacoustic mode, the control device controls the light-emitting unit and the conduction unit 7 to emit light rays 11, and enables the first transducer array 101, the second transducer array 102, and the third transducer array 103 to receive ultrasonic signals. The first transducer array 101 is only used to receive ultrasonic signals and does not emit plane waves. The light-emitting unit and the conduction unit 7 cooperate to emit light rays 11 towards the area to be examined 10. Since the area to be examined 10 has a material with strong optical absorption characteristics, it absorbs light energy and causes thermal expansion to generate ultrasonic signals and propagate them outward. The first transducer array 101, the second transducer array 102, and the third transducer array 103 receive the ultrasonic signals and transmit them to the image processing device. After analog-to-digital conversion by the image processing device, beamforming and image processing are performed to finally generate a photoacoustic image. The generated multispectral photoacoustic image can be used to calculate vascular distribution, hemoglobin concentration distribution, and blood oxygenation protection level.

[0088] When the imaging system is in ultrasound mode only, the control device enables the first transducer array 101, the second transducer array 102, and the third transducer array 103 to receive ultrasound signals, and controls the first transducer array 101 to emit plane waves at three angles toward the part to be examined 10, namely the first ultrasound beam 4, the second ultrasound beam 5, and the third ultrasound beam 6. The ultrasound signals reflected back from the part to be examined 10 can be received by the first transducer array 101, the second transducer array 102, and the third transducer array 103 and transmitted to the image processing device. After analog-to-digital conversion by the image processing device, beamforming and image processing are performed to finally generate an ultrasound image, i.e., an anatomical structure image.

[0089] When the imaging device is in photoacoustic and ultrasonic dual-modal imaging mode, the control device controls the light-emitting unit and the conduction unit 7 to emit light rays 11, and enables the first transducer array 101, the second transducer array 102 and the third transducer array 103 to receive ultrasonic signals. At the same time, the control device controls the first transducer array 101 to emit plane waves at three angles toward the part to be inspected 10. Due to the natural spatial registration, the generated photoacoustic image and ultrasonic image can be seamlessly fused to generate a structural and functional fused image.

[0090] Of course, in other embodiments, when the imaging device is a combination of photoacoustic mode and ultrasonic mode, the control device generates two images, namely an image in photoacoustic mode and an image in ultrasonic mode, both of which are within the protection scope of this invention.

[0091] In other embodiments, the type of control device may be adjusted depending on the design of the heterogeneous probe 1 used for multimodal high-resolution imaging.

[0092] As an alternative implementation, the heterogeneous probe 1 for multimodal high-resolution imaging may not include a control device. In this case, the first transducer array 101, the second transducer array 102, the third transducer array 103 and the conduction unit 7 can be directly connected to the host computer to control the working mode of the heterogeneous probe 1 for multimodal high-resolution imaging.

[0093] According to an embodiment of the present invention, in another aspect, a method of using a heterogeneous probe 1 for multimodal high-resolution imaging is also provided, comprising: Place the part to be inspected 10 within the placement area; Acquire the mode of heterogeneous probe 1 for multimodal high-resolution imaging; If the heterogeneous probe 1 used for multimodal high-resolution imaging is in ultrasonic mode, the first transducer array 101 emits plane waves at at least two angles toward the part to be inspected 10. The first transducer array 101, the second transducer array 102, and the third transducer array 103 receive the ultrasonic signals reflected from the part to be inspected 10. After generating an image based on the ultrasound signal, the ultrasound mode ends. If the heterogeneous probe used for multimodal resolution imaging is in photoacoustic mode, the transmission unit 7 emits light 11 towards the part to be inspected 10; The first transducer array 101, the second transducer array 102, and the third transducer array 103 receive ultrasonic signals emitted by the part to be inspected 10. After generating an image based on the ultrasound signal, the photoacoustic mode ends. If the heterogeneous probe used for multimodal resolution imaging is in photoacoustic-ultrasound dual-modal imaging mode, the ultrasonic mode and photoacoustic mode work alternately. The photoacoustic-ultrasound dual-modal imaging mode ends after at least one image is generated based on the ultrasound signal.

[0094] In this embodiment, the image is a fusion of structural and functional aspects.

[0095] Of course, in other embodiments, there may also be two images, namely an image in photoacoustic mode and an image in ultrasonic mode, both of which are within the protection scope of this invention.

[0096] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
