Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of image processing, and in particular to an ultrasound image rendering method, an ultrasound image rendering device and a storage medium. BACKGROUND

[0002] Ultrasound instruments are generally used for doctors to observe internal tissue structures of a human body. A doctor can obtain an ultrasound image, such as a three-dimensional image, of a part of the human body by operating a probe on a skin surface corresponding to the part. The three-dimensional image is obtained by arranging three-dimensional (3D) data in a certain order after a series of computer processing of continuously collected dynamic two-dimensional (2D) section data, and then rendering the 3D data on a 2D image by using volume rendering technology.

[0003] At present, many different three-dimensional rendering algorithms have been derived based on volume rendering technology. The core idea of the algorithms is as follows: a plurality of light rays are emitted, 3D data sets on a path of each light ray are sampled, and color and transparency are calculated, then the color and transparency are accumulated, and finally the accumulated values are mapped to each pixel of a 2D image, so that a volume rendering image is obtained.

[0004] In order to obtain a more realistic three-dimensional light and shadow effect, volume rendering often needs to combine light and shadow structure information of volume data (such as calculated based on light source type, direction, position and angle). Therefore, for a three-dimensional rendering system with a light and shadow effect, a user is allowed to adjust light source related parameters to obtain more object feature information. Taking the light source direction as an example, considering that the light source direction can actually be rotated at any angle in a three-dimensional space, and the user adjusts the light source direction in a two-dimensional space in actual use, it is difficult for the user to quickly understand the direction indicated by the current light source and how to adjust the light source direction.

[0005] Therefore, how to facilitate the user to understand and use the three-dimensional rendering system so as to obtain a volume rendering image with a realistic three-dimensional light and shadow effect becomes a problem to be solved. SUMMARY

[0047] Embodiments of the present application provide an ultrasound image rendering method, an ultrasound image rendering device and a storage medium. The ultrasound image rendering method can be applied to the ultrasound image rendering device, and is used for image rendering of a target object. The target object can be, for example, biological tissue, such as a part of a human body; and the image rendering can be, for example, volume rendering or surface rendering.

[0048] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0049] Please refer to Figure 1 , Figure 1 A structural schematic block diagram of an ultrasound image rendering device provided by an embodiment of the present application is shown. The ultrasound image rendering device 10 is used to execute the ultrasound image rendering method provided by the embodiments of the present application to render an image.

[0050] As Figure 1 shown, the ultrasound image rendering device 10 can include a processor 11, a memory 12, a probe 13 and a display device 14. The ultrasound image rendering device 10 can be, for example, an ultrasound instrument, or can also be an ultrasound workstation, etc., and is not specifically limited.

[0051] For ease of understanding, the ultrasound image rendering device 10 will be introduced as an ultrasound instrument below, which is used to transmit an ultrasound wave and receive a return wave of the ultrasound wave, and then obtain three-dimensional ultrasound volume data.

[0052] The processor 11 can be a central processing unit (CPU), and can also be other general-purpose processors, digital signal processors (DSP), application specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or the processor can also be any conventional processor.

[0053] The memory 12 can be a volatile memory such as a random access memory (RAM), or a non-volatile memory such as a read only memory (ROM), a flash memory, a hard disk (HDD) or a solid-state disk (SSD), or a combination of the above kinds of memories. The memory 12 is configured to provide the processor 11 with instructions and data.

[0054] The processor 11 is configured to execute the computer programs stored in the memory 12 and, when the computer programs are executed, implement the steps of any of the ultrasound image rendering methods provided in the embodiments.

[0055] The probe 13 emits ultrasound waves to a target object and receives echoes of the ultrasound waves returned from the target object, so as to obtain three-dimensional ultrasound volume data containing features of the target object, which is used for imaging. The processor 11 can store the obtained image in the memory 12, and display the image on the display device 14, so as to facilitate a user (such as a medical staff) to observe.

[0056] In the embodiments of the present application, the display device 14 is mainly used to display the light source control sphere model and the rendered image, such as a volume rendering image or a surface rendering image.

[0057] In some embodiments, the display device 14 can be a touch display screen, a liquid crystal display screen, an LED display screen or an OLED display screen, etc., and can also be a liquid crystal display, a television or a separate display device independent of the ultrasound image rendering device 10, and can also be a display screen on an electronic device such as a mobile phone or a tablet computer, etc.

[0058] It should be noted that the probe 13 can emit ultrasonic waves with different parameters, such as different frequencies and intensities, under the control of the processor 11.

[0059] The probe 13 can be of various types, such as an ultrasonic volume probe or a surface array probe, and is used to emit ultrasonic waves to the target object and receive echoes of the ultrasonic waves to obtain three-dimensional ultrasonic volume data of the target object.

[0060] The ultrasonic image rendering method provided by the embodiments of the present application will be described in detail below in combination with the working principle of the ultrasonic image rendering device 10.

[0061] Please refer to Figure 2 , Figure 2 is a schematic flowchart of an ultrasonic image rendering method provided by the embodiments of the present application. The method can be applied to the ultrasonic image rendering device described above and is used to render images, specifically volume rendering images.

[0062] As shown in Figure 2 , the ultrasonic image rendering method specifically includes steps S101 to S104.

[0063] S101, obtaining three-dimensional ultrasonic volume data.

[0064] The target object is scanned and collected by using an ultrasonic volume probe or a surface array probe to obtain three-dimensional ultrasonic volume data. The three-dimensional ultrasonic volume data is used for volume rendering to obtain a volume rendering image, so that a user can observe the internal tissue structure of the target object through the volume rendering image.

[0065] S102, displaying a light source control sphere model.

[0066] The light source control sphere model is displayed by the display device, so that the user can adjust corresponding light source parameters according to the light source control sphere model. The light source parameters are parameters for volume rendering by the ultrasonic image rendering device according to the three-dimensional ultrasonic volume data. The user can adjust different light source parameters according to the light source control sphere model, and then can render different volume rendering images according to different light source parameters to obtain more object feature information.

[0067] The light source parameters include a light source type, a light source direction, a light source distance, and / or a light source angle.

[0068] The light source control sphere model includes a plurality of control elements, so that the user can adjust the light source type, the light source direction, the light source distance, and / or the light source angle, and other light source parameters according to the plurality of control elements.

[0069] As shown in Figure 3As shown, the control elements of the light source control sphere model 20 include a grid body 21, a light source control 22, a light beam 23, and a coordinate system 24.

[0070] The grid body 21 is a hollow model formed by a plurality of lines, which can be in the shape of a sphere or an ellipsoid, and remains stationary for the operation and contrast reference of other control elements (the light source control 22, the light beam 23, and the coordinate system 24).

[0071] The plurality of lines can be solid or dashed lines, straight or curved lines, etc., which are not limited in particular, and are used to combine into a hollow model as a reference object to improve the reference effect, thereby facilitating user understanding and use and improving user experience.

[0072] In some embodiments, the brightness of the lines in the grid body 21 near the light source control 22 is greater than that of the lines far from the light source control 22, that is, the lines near the light source control 22 are highlighted, and the lines far from the light source control 22 are displayed in low brightness, wherein the change between high brightness display and low brightness display is gradual. Thus, the lines in the grid body 21 change with the light source control 22 to better indicate the light source direction, and facilitate the user to more realistically understand and feel the effect of the change of the light source direction on the drawing image.

[0073] The lines of the grid body 21 are semi-transparent processed, so as to better show the changes of the light beam 23 and the coordinate system 24.

[0074] The light source control 22 can rotate around the grid body 21 to indicate the light source direction, or move along the light source direction relative to the grid body 21 to indicate the light source distance. This facilitates the user to observe the changes of the light source direction and the light source distance through the light source control.

[0075] For example, the light source control 22 moves away from the grid body 21 along the light source direction, indicating that the light source distance relatively increases; the light source control 22 moves closer to the grid body 21 along the light source direction, indicating that the light source distance relatively decreases.

[0076] The shape of the light source control 22 includes a plurality of shapes, and different shapes of the light source control 22 represent different light source types, wherein the light source types include a point light source, a parallel light source, and a spotlight. Thus, it is convenient for the user to understand the change of the light source type, while improving the user experience.

[0077] For example, the shape of the light source control 22 includes a flashlight, a sphere, or a bulb, as shown in Figure 4a , Figure 4b and Figure 4c . Among them, the flashlight represents a parallel light source, the sphere represents a point light source, and the bulb represents a spotlight.

[0078] For example, the shape of the light source control 22 can also include a cylinder, a sphere or a cone, which respectively represent a parallel light source, a point light source and a spotlight.

[0079] It can be understood that the shape of the light source control 22 includes other similar shapes to represent different light source types.

[0080] When the shape of the light source control 22 changes, the light source type also changes, and the light source direction can also change, thereby helping the user to understand the change of the related light source parameters.

[0081] In some embodiments, the area of the light source control 22 facing the user's viewing side is highlighted, that is, the area of the light source control 22 close to the front of the screen of the display device is highlighted, to enhance the stereoscopic effect of the light source control 22.

[0082] In some embodiments, the highlighting or low-lighting of the lines in the grid body 21 can also be different according to different light source types, thereby facilitating the user's understanding.

[0083] When the light source type changes, the corresponding light beam also changes, and the display brightness of the lines irradiated by the light source is also different.

[0084] For example, the brightness of the lines in the grid body 21 located in the irradiated part is greater than the brightness of the part not irradiated, and the brightness of the part close to the light source control 22 is greater than the brightness of the part away from the light source control 22.

[0085] It can be understood that the higher the brightness, the higher the highlighting, and the lower the brightness, the lower the low-lighting, and the highlighting and the low-lighting gradually change.

[0086] It should be noted that the light source control ball model 20 can have multiple light source controls 22 at the same time, depending on the actual number of light sources.

[0087] The light beam 23 is emitted by the light source control 22 and is linked with the light source control 22 to indicate the light source direction and the light source angle.

[0088] The linkage with the light source control 22 means that the light beam 23 moves with the movement of the light source control 22, or drives the movement of the light source control 22, and the movement of the light source control 22 and the light beam 23 is relative to the grid body 21. Thus, it can assist the user to understand and use the light source parameters such as the light source direction and the light source angle.

[0089] For example, the light beam 23 is linked with the light source control 22, and the movement of the light beam 23 is relative to the grid body 21, which includes rotating relative to the grid body 21, or moving in the light source direction, such as extending or shortening.

[0090] When the light source type is switched according to the shape of the light source control 22, the shape of the light beam 23 changes accordingly.

[0091] For example, the parallel light source corresponds to a cylinder, the point light source corresponds to a polygon, and the spotlight corresponds to a circular cone. When the user switches the shape of the light source control 22 from a flashlight to a light bulb, the shape of the light beam 23 changes from a cylinder to a cone. By changing the shape setting and changing with the light source control, the user can further understand the light source parameters such as the light source direction and the light source angle.

[0092] It can be understood that the shape of the light beam 23 can be a shape similar to the light source type in addition to the cylinder, polygon, cone, etc., which is not limited here.

[0093] When the light source is a spotlight, the light source angle changes, and the shape of the light beam also changes, such as the size of the vertex angle of the cone also changes. Further, the size of the light source angle is reflected by the size of the light beam, so that the user can observe the change of the light source angle.

[0094] In some embodiments, the light beam 23 can be translucent. The light beam 23 extends from the light source control 22 to the center of the grid body 21, and the brightness of the light beam 23 gradually darkens from the light source control 22 to the center of the grid body 21, thereby increasing the display effect of the light beam 23 and effectively assisting in understanding the light source parameters such as the light source direction and the light source angle.

[0095] The coordinate system 24 is located in the hollow model and is linked with the light source control 22 to assist in indicating the light source direction, so that the user can understand the light source parameters such as the light source direction.

[0096] Specifically, the coordinate system 24 can be a Cartesian coordinate system, and the origin of the Cartesian coordinate system is located at the center of the grid body 21. The three axes of the Cartesian coordinate system are displayed in different colors for differentiation, so that the user can observe.

[0097] For example, the colors of the three axes can be red, green, and yellow, and of course can also be other combinations of colors, which are not limited here.

[0098] It can be understood that other different ways of display can also be used for differentiation.

[0099] For example, the three axes of the Cartesian coordinate system are displayed in different gray values; or displayed in lines with different thicknesses; or displayed in lines with different specific shapes, such as solid lines or dashed lines. Or a combination of multiple ways, which is not limited in the embodiments of the present application.

[0100] The one of the axes of the Cartesian coordinate system points to the light source control 22 and is linked with the light source control 22, and the length of the axis pointing to the light source control 22 is greater than the lengths of the other two axes. The axis being linked with the light source control 22 means that the axis always points to the light source control 22 no matter how the light source control 22 rotates.

[0101] In an embodiment, in order to increase the stereoscopic effect, the area of the Cartesian coordinate system 24 facing the side of the user's view is highlighted. That is, the area of the Cartesian coordinate system 24 close to the front of the screen of the display device is highlighted to enhance the stereoscopic effect of the Cartesian coordinate system 24.

[0102] In one embodiment, the control elements of the light source control sphere model 20 can also only include the grid body 21 and the light source control 22, and do not include the light beam 23 and the Cartesian coordinate system 24. Alternatively, in one embodiment, the control elements of the light source control sphere model 20 can also only include the grid body 21, the light source control 22 and the light beam 23, or only include the grid body 21, the light source control 22 and the Cartesian coordinate system 24.

[0103] S103, obtaining the light source parameters adjusted by the user based on the light source control sphere model, and drawing and displaying the light source control sphere model according to the adjusted light source parameters.

[0104] After displaying the light source control sphere model 20, the light source control sphere model 20 displayed therein includes a plurality of control elements, such as the grid body 21, the light source control 22, the light beam 23 and / or the Cartesian coordinate system 24. Thus, the user can adjust the corresponding light source parameters based on each control element of the light source control sphere model, and obtain the light source parameters adjusted by the user.

[0105] The light source control sphere model is redrawn in real time according to the adjusted light source parameters, and the redrawn light source control sphere model is displayed, thereby helping the user to understand the changes of the related light source parameters through the redrawn light source control sphere model.

[0106] In some embodiments, the light source parameters adjusted by the user based on the light source control sphere model can be specifically determined according to the operation of the user on the light source control sphere model. Thus, it is convenient for the user to understand the adjusted light source parameters, and the user experience is improved, and the influence of the light source parameters on image rendering is deepened.

[0107] For example, the user performs a first preset operation on the light source control sphere model, and the first preset operation of the user based on the light source control sphere model is obtained, and the light source type is determined according to the first preset operation.

[0108] The first preset operation includes one of rotating a mouse scroll wheel, clicking a left or right mouse button, operating a touch screen and operating a physical control, and can also be other operation modes, which are not limited herein.

[0109] For example, the user rotates the mouse wheel to select the light source type. When the user switches the shape of the light source control from a flashlight to a sphere by rotating the mouse wheel, it is determined that the user selects a point light source.

[0110] For example, the user switches the light source type by clicking the left and right keys of the mouse.

[0111] For example, the user switches the light source type by operating the physical control (such as a button, a knob, a sliding bar, etc.).

[0112] For example, the user performs a second preset operation on the light source control sphere model. The second preset operation of the user based on the light source control sphere model is obtained, and the light source direction is determined according to the second preset operation.

[0113] The second preset operation includes one of moving a mouse, rotating a mouse wheel, clicking left and right keys of a mouse, operating a touch screen, moving a trackball, and operating a physical control. Of course, other operation modes can also be used, which are not limited herein.

[0114] For example, the user clicks the light source control by the mouse and moves it. The light source direction is changed according to the moving track of the mouse. It is determined that the user selects a point light source. Alternatively, the user moves the mouse, and the light source direction is mapped by calculating the direction of the last two mouse movements.

[0115] For example, the user rotates the mouse wheel. Each rotation moves the current light source direction by a certain angle in a certain direction until the light source direction is moved to the user's needs. Alternatively, the user clicks the left and right keys of the mouse. Each click moves the current light source direction by a certain angle in a certain direction until the light source direction is moved to the user's needs.

[0116] For example, the user moves the light source control (also called a trackball) around the grid. The direction of the last two trackball movements is calculated to map the light source direction.

[0117] For example, the user operates the physical control (such as a button, a knob, a sliding bar, etc.). Each operation moves the current light source direction by a certain angle in a certain direction until the light source direction is moved to the user's needs.

[0118] For example, the user performs a third preset operation on the light source control sphere model. The third preset operation of the user based on the light source control sphere model is obtained, and the light source distance is determined according to the third preset operation.

[0119] The third preset operation includes one of moving a mouse, rotating a mouse wheel, clicking left and right keys of the mouse, operating a touch screen, moving a trackball, and operating a physical control. Of course, other operation modes can also be used, which are not limited herein.

[0120] For example, the user moves the mouse, and the distance of the last two mouse movements is calculated to map to the light source distance. For example, the light source distance is changed according to the distance of the mouse movement. Alternatively, the user rotates the mouse wheel, and the current light source distance is increased or decreased by a specific distance each time the rotation occurs. Alternatively, the left and right keys of the mouse are clicked, and the current light source distance is increased or decreased by a specific distance each time the click occurs.

[0121] For example, the user moves the trackball, and the distance of the last two trackball movements is calculated to map to the light source distance. Alternatively, the user drags the trackball, and the drag distance of the dragged trackball is calculated to map to the light source distance.

[0122] For example, the user operates the physical control (for example, a key, a knob, a sliding bar, and the like), and the current light source distance is increased or decreased by a specific distance each time the operation occurs, until the light source distance is moved to the user's requirement.

[0123] For example, the user performs a fourth preset operation on the light source control ball model, the fourth preset operation of the user based on the light source control ball model is obtained, and the light source angle is determined according to the fourth preset operation.

[0124] The fourth preset operation includes one of moving a mouse, rotating a mouse wheel, clicking left and right keys of the mouse, operating a touch screen, moving a trackball, and operating a physical control. Of course, other operation modes can also be used, which are not limited herein.

[0125] For example, the user moves the mouse, and the distance of the last two mouse movements is calculated to map to the light source angle. Alternatively, the user rotates the mouse wheel, and the current light source angle is increased or decreased by a specific angle each time the rotation occurs. Alternatively, the user clicks the left and right keys of the mouse, and the current light source angle is increased or decreased by a specific angle each time the click occurs.

[0126] For example, the user moves the trackball, and the angle of the last two trackball movements is calculated to map to the light source angle.

[0127] For example, the user operates the physical control (for example, a key, a knob, a sliding bar, and the like), and the current light source angle is increased or decreased by a specific angle each time the operation occurs.

[0128] The physical control includes a key, a knob, or a sliding bar. Of course, other forms of physical keys can also be used, which are not limited herein.

[0129] It should be noted that in some embodiments, the first preset operation, the second preset operation, the third preset operation and the fourth preset operation are different from each other, thereby avoiding the same operation.

[0130] In some embodiments, the light source control sphere model is redrawn according to the adjusted light source parameters, specifically, the grid body 21, the light source control 22, the light beam 23 and the coordinate system 24 of the light source control sphere model are redrawn according to the adjusted light source type, light source direction, light source distance and / or light source angle. So that the user can intuitively observe the changes of the adjusted light source parameters.

[0131] For example, the shape of the light source control can be changed according to the adjusted light source type, wherein different light source types correspond to light source controls with different shapes, and the light source types include point light source, parallel light source and spotlight. The shapes of the corresponding light source controls are respectively sphere, flashlight or bulb, etc. So that the user can understand and use the light source type when drawing the image.

[0132] For example, the shape of the light source control is switched from sphere to flashlight if the user adjusts the light source type to parallel light source.

[0133] For example, the light source control can be controlled to rotate around the grid body according to the adjusted light source direction. Alternatively, the light source control can also be controlled to move along the light source direction according to the adjusted light source distance. So that the user can understand and use the light source direction and light source distance when drawing the image.

[0134] For example, the shape of the light beam can be changed according to the adjusted light source type, wherein different light source types correspond to light beams with different shapes. To assist the user in understanding and using the light source type when drawing the image.

[0135] For example, the shape of the light beam is switched from cone to cylinder if the user adjusts the light source type to parallel light source.

[0136] For example, the light beam can also be controlled to rotate around the grid body according to the adjusted light source direction, wherein the rotation of the light beam is linked with the light source control, and the linkage is that the light source control rotates around the grid body and drives the light beam to rotate synchronously. To assist the user in understanding the change of the light source direction.

[0137] For example, the light beam can be controlled to move along the light source direction according to the adjusted light source distance. Alternatively, if the light beam is in the form of a cone, the size of the vertex angle of the cone can be changed according to the adjusted light source angle. This helps the user to understand the changes in the light source distance and the light source angle.

[0138] For example, the coordinate system can be controlled to rotate around the grid body according to the adjusted light source direction, wherein the rotation of the coordinate system is linked to the light source control, and the linkage is that the light source control rotates around the grid body and simultaneously drives the coordinate system to rotate. This helps the user to understand the change in the light source direction through the coordinate system.

[0139] For example, the coordinate system can be a Cartesian coordinate system, the origin of the Cartesian coordinate system is located at the center of the grid body, and the three axes of the Cartesian coordinate system are displayed in different colors; one of the axes of the Cartesian coordinate system points to the light source control, and the axis is linked to the light source control, and the length of the axis pointing to the light source control is greater than the lengths of the other two axes. This is for the user to observe.

[0140] It can be understood that in the embodiments of the present application, the coordinate system can of course be other types of coordinate systems.

[0141] S104, volume rendering is performed according to the adjusted light source parameters and the three-dimensional ultrasound volume data to obtain a volume rendering image.

[0143] Specifically, the volume rendering can be performed according to a plurality of different three-dimensional rendering algorithms, such as using a ray casting technique to render a volume rendering image from the three-dimensional ultrasound volume data, and the obtained volume rendering image is an ultrasound image.

[0144] In some embodiments, as Figure 5 As shown, after obtaining the volume rendering image, the volume rendering image 30 can also be displayed on the interface displaying the rendered light source control sphere model 20, so that the user can observe the changes in the adjusted light source parameters and the effects on the volume rendering image, and make corresponding adjustments to obtain more internal tissue information.

[0145] For example, the interface displaying the rendered light source control sphere model can be divided into a first display area and a second display area, wherein the first display area is used to display the rendered light source control sphere model, and the second display area is used to display the volume rendering image.

[0146] For example, in order to facilitate the user to understand the light source parameters, the first display area can be set as a main display area, and the second display area can be set as an auxiliary display area. For example, the display area of the first display area is set to be larger than the display area of the second display area. Of course, the display mode of the main display area and the auxiliary display area can also be realized by other modes.

[0147] It should be noted that the steps S101 and S102 have no sequence, and the three-dimensional ultrasound volume data can be acquired first, and then the light source control sphere model is displayed; or the light source control sphere model can be displayed first, and then the three-dimensional ultrasound volume data is acquired; or the three-dimensional ultrasound volume data is acquired while the light source control sphere model is displayed.
