Description

Technical Field

[0001] The present invention relates to the field of image processing technology, and in particular to a medical image processing method and device, and more particularly to an MRI image processing method and device. Background Art

[0002] With the development of computer technology, current users generally watch images on computer screens and make work decisions. Taking hospitals as an example, doctors currently generally watch MRI images on computer screens to judge the condition. However, many hospitals currently use old computers that are equipped with MRI equipment manufacturers (for example, the computers equipped with MRI equipment manufacturers in some hospitals are old computers around 2000). Due to the old hardware and long use time, the speed of reading MRI images is slow, which seriously affects the diagnosis and treatment efficiency of doctors. One solution is to replace newer computers, but because the computers equipped with MRI equipment manufacturers are loaded with MRI equipment operating software protected by intellectual property rights (this type of software has the function of operating MRI equipment and receiving signals from MRI equipment to generate MRI images), replacing computers requires paying expensive software fees to MRI equipment providers, which makes it impossible for some hospitals to improve the display speed of MRI images by replacing computers. Similarly, similar problems exist in other fields. For example, in the field of professional sports training, some sports analysis software providers often do not provide sports analysis software separately, but force users to purchase computers with software installed, which also makes it difficult to upgrade computers. There is also a need to improve the image reading speed in such fields. In addition, the problem of slow image reading speed also exists in the field of security monitoring. Due to the need to control the cost of security monitoring equipment, security monitoring equipment (such as computers in the monitoring room) may be computers with poor performance. There is also a need to improve the image reading speed in this field. Summary of the invention

[0023] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0024] As described in the background technology, hospitals currently often encounter the problem of slow MRI image reading speed (obviously, the technology and concept of the present invention can also be applied to other fields, such as sports training monitoring or security monitoring, but for the convenience of discussion, the present invention is introduced by taking MRI images as an example), and there is a technical solution to solve this technical problem in the prior art. Prior art CN102915521A discloses a mobile terminal image processing method and device. The core of this prior art is that the region of interest detection part fully considers the prior information of the user's target of interest known in advance, thereby improving the accuracy of the region of interest detection, and the region of interest resolution improvement part only improves the resolution of the detected region of interest to improve the processing speed. However, for the field of MRI image processing or the field of security monitoring images, this method of determining the region of interest based on prior information and only improving the resolution of the region of interest is not suitable. Taking MRI images as an example, the patient's lesions appear in different positions in the MRI image, and the doctor cannot provide the computer with prior information of the user's target of interest. Prior art CN109194923A also relates to a technology for improving the resolution of a certain part of an image. The prior art allows one or more regions of interest to be set based on a user's manual input, but the prior art does not disclose how the user interacts with the computer to set the one or more regions of interest. In the prior art, the way the user interacts with the computer may be very inflexible, which increases the difficulty of use for the user. The method of the present invention is intended to solve the problems of the prior art. Example 1

[0025] Figure 1 1 is a method flow chart of an embodiment of the present invention. As shown in the figure, the method of the present invention includes the following steps: Step 1: The display terminal provides a first low-resolution image to the user, wherein the first low-resolution image is divided into a first block set by the display terminal in a first division manner, wherein each block in the first block set has a boundary line, and each block in the first block set has the same first size; for the convenience of the following discussion, the following uses an MRI image as an example of an image, and of course, those skilled in the art can understand that the image in the present invention can be an image of an athlete in motion, or a security monitoring image; the display terminal provides the first low-resolution image to the user, which can be the display terminal showing the first low-resolution image to the user on a display, as an example, the low-resolution image can be an image of 400 (horizontal pixel number) × 300 (vertical pixel number) (and the clarity of each block in the low-resolution image is equivalent to that of a 400×300 image), and the high-resolution image can be an image of 800×600 (and the clarity of each block in the high-resolution image or the high-resolution block is equivalent to that of an 800×600 image), and those skilled in the art can understand that the aforementioned resolutions are only exemplary and provided only for the convenience of discussing the problem, and other resolutions can be applicable to the present invention; Figure 2 It is a schematic diagram of a display interface according to an embodiment of the present invention. Figure 2 The computer screen of the display terminal is schematically shown in the figure, wherein the computer screen is divided into two parts, the left part is the image display area, and a low-resolution image or a high-resolution image or an image mixed with a low-resolution block and a high-resolution block is displayed in the image display area. It should be understood that no matter which image is displayed, the image needs to cover the entire image display area, that is, the low-resolution image, the high-resolution image, and the image mixed with a low-resolution block and a high-resolution block have the same size. The right side of the computer screen is the function button area. As shown in the figure, the function button area includes multiple buttons for increasing the block size, reducing the block size, hiding the block boundary line, determining the adjustment of the block boundary line, and determining the selected block. The user can click the corresponding button with the mouse to trigger the corresponding function (the specific function is described in detail below). In addition, the function button area may also have other function buttons; in the present invention, each block in the first block set has a boundary line, and in the display, the boundary line of the block needs to be displayed to the user; Step 2: The user determines whether the first size of the block of the first low-resolution image divided in the first division manner meets the requirement; Figure 3 1 is a schematic diagram of a first low-resolution image divided by a first division method according to an embodiment of the present invention. As shown in the figure, the first division method is to divide a frame of 400×300 image into 12 blocks, each block has 100×100 pixels, and the size of the block may refer to the area occupied by the block. It can be understood by those skilled in the art that the larger the block, the larger the pixels of each block; Figure 3 Each block in the image is a square, and the four sides of the square are the boundary lines of the block. It can be seen that the boundary lines are actually displayed on the display and are visible to the user; Step 3: If the user determines that the first size of the block of the first low-resolution image divided in the first division manner does not meet the requirement, the user sends a first instruction to the display terminal, wherein the first instruction instructs the display terminal to increase the size of the block of the first low-resolution image; in an example, the user may send the first instruction to the display terminal by clicking a button for increasing the block size with a mouse; the reason why the first size of the block of the first low-resolution image does not meet the requirement may be that the lesion spans across multiple blocks, which may cause the user to click multiple blocks, and in this case it can be determined that the first size of the block of the first low-resolution image does not meet the requirement; Step 4: After the display terminal receives the first instruction, the display terminal provides a second low-resolution image to the user, wherein the second low-resolution image is divided into a second block set by the display terminal in a second division manner, wherein each block in the second block set has a boundary line, and each block in the second block set has the same second size, wherein the second size is larger than the first size. Figure 4 : is a schematic diagram of a first low-resolution image divided by a second division method according to an embodiment of the present invention. As shown in the figure, the first division method is to divide a frame of 400×300 image into 6 blocks, each block has 200×100 pixels, and the size of the block can refer to the area occupied by the block. It can be understood by those skilled in the art that the larger the block, the larger the pixels each block has. The block size can be several fixed values ​​pre-configured by the display terminal. If the user wants the block size to be larger, the display terminal can select a larger size from several pre-configured fixed values ​​to divide the block. Of course, there is also a situation where the user thinks that the block is too large. At this time, the user can click the reduce block size button, and then the display terminal can select a smaller size from several pre-configured fixed values ​​to divide the block. Example 2

[0026] In embodiment 2, the method further comprises: If the user determines that the first size of the block of the first low-resolution image divided in the first division manner meets the requirement, the user determines the region of interest in the first low-resolution image; The user determines whether the region of interest is located in a block of the first low-resolution image; If the user determines that the region of interest is located in a block of the first low-resolution image, the user clicks the first block, wherein the first block is a block of the first low-resolution image where the region of interest is located; Figure 5This is a schematic diagram of an embodiment of the present invention in which a region of interest is located in a block of a first low-resolution image. As shown in the figure, the region of interest is located in the block of the second row and the second column. For an MRI image, the region of interest is generally a lesion area. However, since the resolution of the block (and the entire first low-resolution image) is low, the edge of the lesion area may not be clearly distinguished, and the contrast of the lesion area may not be clear enough. Therefore, doctors generally need at least a higher-resolution image of the block to further determine the condition. The user can use the mouse to click on the block of the second row and the second column, and then the computer screen can highlight the edge of the block to prompt the user that the block has been selected, and then the user can click Figure 2 A button for confirming the selected block shown in , to indicate to the display terminal that the user has confirmed the selected block; After the display terminal determines that the user clicks on the first block, the display terminal replaces the first block of the first low-resolution image with the first block of high resolution. After the user selects a block, the display terminal can determine which block the user has selected based on the pixel coordinates of the four corner points of the block in the second row and second column, and retrieve the data of the high-resolution image corresponding to the block from the memory. The graphics card of the display terminal then uses the data of the high-resolution image corresponding to the block to perform known graphics card pipeline processing (such as rendering, etc.), and then uses the generated high-resolution block image to replace the Figure 5 The low-resolution block in the second row and second column. Example 3

[0027] In embodiment 3, the method further comprises: If the user determines that the region of interest is located in multiple blocks of the first low-resolution image, the user continues to determine whether the region of interest can be located in one block of the first low-resolution image by adjusting the block boundary line; If the user determines that the region of interest can be located in a block of the first low-resolution image by adjusting the block boundary line, the user adjusts the boundary line of the second block so that the region of interest is located only in the second block; Figure 6 is a schematic diagram of an embodiment of the present invention in which the region of interest is located in multiple blocks of a first low-resolution image, such as Figure 6As shown, the region of interest (such as the lesion in the MRI image) spans two adjacent blocks, but the lesion is basically located in the block of the second row and second column, and only a small part is located in the block of the second row and third column. At this time, if the display terminal only provides the user with the function of selecting the block of the second row and second column and the block of the second row and third column, most of the information in the high-resolution image of the block of the second row and third column provided by the display terminal is useless information, which is not conducive to improving the image reading speed; therefore, embodiment 3 provides the function of adjusting the block boundary. Specifically, the user can use the mouse to drag the right boundary of the block of the second row and second column to expand the area of ​​the block of the second row and second column, so that the block of the second row and second column can accommodate the entire lesion area after adjustment. Of course, those skilled in the art should understand that if the user adjusts the block size by adjusting the block boundary line, it is no longer required that each block has the same size; see the schematic diagram of the user adjusting the block boundary line. Figure 7 After adjusting the block boundary line with the mouse, the user can click Figure 2 The OK button for adjusting block boundary line is pressed to indicate to the display terminal that the user has completed the adjustment of the block boundary line.

[0028] After the display terminal determines that the user has adjusted the boundary line of the second block, the display terminal determines the second block after the adjusted boundary line; after the user adjusts the block boundary line, the display terminal can determine the block in the second row and second column after the adjusted boundary line based on the pixel coordinates of the four corner points of the block in the second row and second column after the adjusted boundary line (the block has become a rectangle at this time), and retrieve the data of the high-resolution image corresponding to the block in the second row and second column after the adjusted boundary line from the memory.

[0029] After the display terminal determines the second block after the adjustment boundary line, the display terminal replaces the second block after the adjustment boundary line of the first low-resolution image with the second block after the adjustment boundary line of the high-resolution image. Example 4

[0030] In embodiment 4, the method further comprises: If the user determines that the region of interest cannot be located in a block of the first low-resolution image by adjusting the block boundary line, the user clicks the third block, the fourth block and the fifth block, wherein the third block, the fourth block and the fifth block are multiple blocks of the first low-resolution image where the region of interest is located; for example, if lesions appear in multiple mutually discontinuous blocks, at this time, it is difficult to accommodate multiple lesions in one block by adjusting the block boundary line. If it is difficult to accommodate multiple lesions in one block by forcibly adjusting the block boundary line, it will cause difficulty in user operation and cause a large amount of useless information to appear in the high-resolution block; After the display terminal determines that the user clicks the third block, the fourth block and the fifth block, the display terminal determines whether the third block, the fourth block and the fifth block are continuous blocks; the operation method of the user clicking the block has been described in detail in the previous embodiment, and the operation here is similar and will not be repeated.

[0031] If the display terminal determines that the third block, the fourth block and the fifth block are discontinuous blocks, the display terminal replaces the third block, the fourth block and the fifth block of the first low-resolution image with the third block, the fourth block and the fifth block of the high-resolution image. The schematic diagram of the discontinuity of the third block, the fourth block and the fifth block can be seen in Figure 8 , the third block, the fourth block and the fifth block are not continuous with each other means that there is no common boundary line between the third block, the fourth block and the fifth block. Example 5

[0032] In embodiment 5, the method further comprises: If the display terminal determines that the third block, the fourth block and the fifth block are continuous blocks, the display terminal determines the center positions of the third block, the fourth block and the fifth block; Fig. 9 An example is shown in which the third block, the fourth block and the fifth block are continuous with each other; the center positions of the third block, the fourth block and the fifth block can be determined by a known geometric method, or the user can inform the display terminal by clicking the mouse in which block the main body of the lesion is located. For example, the user can inform the display terminal by clicking the mouse that the main body of the lesion is located in the third block, and the display terminal can set the center position in the third block, which is substantially located at the center of the third block (that is, the center of the square), but slightly offset toward the fourth block and the fifth block; The display terminal re-divides the blocks based on the center positions of the third block, the fourth block and the fifth block to obtain a sixth block, wherein the size of the sixth block is smaller than the sum of the sizes of the third block, the fourth block and the fifth block; an example of the sixth block obtained by re-dividing the blocks can be seen in Fig. 9 , and then Fig. 9 As shown, the re-divided sixth block may still not be able to accommodate the lesion. At this time, the user can use the method of adjusting the block boundary line mentioned in the previous embodiment to adjust the boundary line of the sixth block again, so that the sixth block can accommodate the lesion. Re-dividing the blocks based on the center positions of the third block, the fourth block and the fifth block to obtain the sixth block can be based on the pixel coordinates of the center positions of the third block, the fourth block and the fifth block of the display terminal, and then forming a square with the pixel coordinates of the center position as the center. The size of the square can be determined by a simulation test method. The display terminal replaces the designated area of ​​the first low-resolution image with the sixth block of high resolution, wherein the designated area of ​​the first low-resolution image is the area of ​​the first resolution image corresponding to the sixth block of high resolution.
