Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problem that the color phase value of a focus image cannot be effectively reduced by the existing color reduction method, the invention provides a mononuclear focus color phase reduction method which can effectively reduce the color phase of a mononuclear focus area according to a focus diffusion rule so as to obtain a focus restoration image meeting the focus diagnosis requirement. Referring to fig. 1, fig. 1 is a flowchart of a mononuclear focus hue restoration method according to an embodiment of the present invention, where the method may include:
s101, acquiring a near-infrared image of the binuclear focus.
The binuclear focus near-infrared image is a color image obtained by performing near-infrared shooting on a focus region containing two focus nuclei (diffusion centers of focuses), and different Hue values (Hue) can be used for expressing the concentration of the focuses, so that medical personnel can analyze the diffusion conditions of the focuses according to the Hue value distribution in the image. It should be noted that, the embodiment of the present invention does not limit the specific acquisition parameters of the near-infrared image of the binuclear lesion, and can be set according to the actual application requirements. It should be noted that, although the embodiment of the present invention is described by using a dual-core lesion near-infrared image, this is only because the description of the present method based on a multi-core lesion near-infrared image including two or more lesion cores will make the text redundant, and in practical applications, the present method may also be used in a near-infrared image including two or more multi-core lesions.
S102, determining a mononuclear lesion area containing a lesion core area and a hue restoration area in the binuclear lesion near-infrared image, and generating a first ray and a second ray which take the core center of the lesion core area as a starting point and are tangent to the hue restoration area.
It should be noted that the mononuclear lesion region is a lesion region containing only a single lesion nucleus, wherein the lesion nucleus is a diffusion center of the lesion, i.e., a position with the highest concentration in the mononuclear lesion region. In the medical field, these mononuclear lesion areas often overlap with each other, which may cause a color overlap or discoloration, and may easily interfere with the analysis of the diffusion of a single lesion by medical personnel. Therefore, how to restore the hue value of the overlapped part of the mononuclear lesion area and other lesions has an important role in improving the analysis effect of medical personnel on the diffusion condition of the mononuclear lesion area.
In order to solve the above problems, in an embodiment of the present invention, a primary extraction is performed on a binuclear lesion near-infrared image to obtain a mononuclear lesion region including a lesion core region and a hue restoration region, where the hue restoration region is an overlapping portion of the mononuclear lesion region and other mononuclear lesion regions. Specifically, in a binuclear near-infrared image of a lesion, the hue value of a lesion region is usually larger than that of a normal region, so that the lesion region can be extracted by using a preset hue value range; in addition, since the hue value of the lesion increases as its concentration increases and the concentration of the nucleus region of the lesion is generally higher than other portions in the lesion region, the hue value of the nucleus region of the lesion is greater than other portions in the lesion region, and the nucleus region of the lesion may be extracted in the lesion region using another preset hue value range. It should be noted that, the embodiment of the present invention does not limit the preset hue value range used for extracting the lesion area and the lesion core area, and can be set according to the actual application requirements.
Further, because the diffusion of the focus basically conforms to a diffusion equation, namely, the diffusion speed from the focus nucleus to the periphery is basically uniform, after the focus nucleus region is obtained, the nucleus center of the focus nucleus region can be set as the circle center and a corresponding circular region can be drawn, so that the position of the mononuclear focus region and the overlapping region between the adjacent mononuclear focus regions can be preliminarily determined. For example, for a mononuclear lesion region, the center of gravity of the lesion core region may be taken as the core center, the closest distance between the core center and the edge of the lesion region may be determined, a circular region may be generated for the mononuclear lesion region with the core center as the center and the closest distance as the radius, and the approximate position of the mononuclear lesion region may be determined based on the circular region. Of course, in practical situations, there may be a difference in the diffusion speed of the lesion nuclei around the breast, for example, when the lesion is located in the breast area, the diffusion may be affected by the breast density, so that when the position of the mononuclear lesion area is determined, the correction may be performed according to the practical situation, please refer to the description in the following embodiments. It should be noted that the embodiment of the present invention does not limit how to determine the center of gravity of the lesion core area, for example, the coordinate values of each pixel point in the lesion core area may be averaged, and a point corresponding to the average value may be set as the core center of the lesion core area.
Further, please refer to the description in the following embodiments for specific applications and drawing manners of the first ray and the second ray drawn in the embodiments of the present invention.
S103, determining a first radian of the polar angle corresponding to the first ray and a second radian of the polar angle corresponding to the second ray in a preset polar coordinate system with the nuclear center as an origin.
In embodiments of the present invention, it is contemplated that the diffusion of a lesion generally follows the law of diffusion, and thus, the lesion may be hue restored according to the law. Specifically, the diffusion law refers to the mass and concentration of a diffusing substance flowing through a curved surface per unit area in the normal direction n within a unit time
Directional derivative along normal direction n
Proportional ratio, where x, y, z represent three directions in a three-dimensional coordinate system, and t represents time. The diffusion equation can be expressed as:
Wherein
Indicating the diffusion coefficient, the negative sign appears because the substance always permeates from the side with a high concentration to the side with a low concentration. By transforming equation 1, we can get:
Wherein the left half of equation 2 is the rate of diffusion of the substance across the cross-section
. Assuming a uniform cross-section, the linear velocity of the mass flow is:
Wherein A is a constant. Since the binuclear near-infrared image of the lesion is two-dimensional, the component on the z-axis is 0, and therefore the above equation can be transformed into:
Wherein
Can express diffusion speed in x and y directions and has the unit of
. From the conservation of mass equation, a variant of the diffusion equation can be obtained:
D here can be regarded as a constant coefficient. Similarly, the diffusion equation in one dimension can be derived:
In the case of the breast, the diffusion rate in the same direction in the breast of the tumor cells is also substantially uniform due to the substantially same density. Let a, B be two rays with focus diffusion center (nuclear center) as starting point, A, B are respectively positioned on ray a and ray B, the diffusion time and diffusion concentration corresponding to these two points are identical, in which the distance between A point and diffusion center is
The distance from point B to the diffusion center is
Then based on equation 6 one can get:
The two formulas are divided to obtain:
If the straight line a is known, i.e. C and
given this, then:
On the basis, if the focus nuclear region is determined, the ratio of Db to Da can be solved by using the distance from the intersection point of the ray and the focus nuclear region edge to the diffusion center. Specifically, the distance from the intersection point of the ray a and the edge of the focal nucleus region to the diffusion center is set as
The distance from the intersection point of the ray b and the edge of the focal nucleus region to the diffusion center is
Then, one obtains:
Substituting equation 11 into equation 10 can result in:
Then the concentration at Δ xb is the concentration at Δ xa (the density of the lesion), i.e. the color degrees of the two are the same.
Further, since the density of the breast actually changes in the actual situation, that is, the density gradually increases from the root to the head, the diffusion coefficient D in the same direction does not change, and it is necessary to neutralize and reduce the diffusion coefficient change caused by density conversion. Specifically, referring to fig. 2, fig. 2 is a schematic view of a lesion according to an embodiment of the present invention, in which a point O is a core center, an upward arrow with the point O as an origin represents a polar axis in a preset polar coordinate system, c and d are two rays with the point O as an origin and tangent to a color restoration region, and radians corresponding to polar angles between the two rays and the polar axis are respectively shown as
And
the point C and the point D are respectively located on the ray C and the ray D and have the same concentration (that is, the hue value is the same), the point E is a point having the same concentration as the point C and the point D in the color restoration region, and the radian corresponding to the polar angle between the ray (hereinafter, simply referred to as the ray E) passing through the point E with the core center as the starting point and the polar axis is
. Because the change of the normal breast density is generally linear, the change can imitate an arc line which is sent from the point C, passes through the point E and reaches the point D, the concentration of each point on the arc line is the same, the diffusion coefficients at the two ends of the arc line are the diffusion coefficient Dc corresponding to the point C and the diffusion coefficient Dd corresponding to the point D, and the diffusion coefficient on the arc lineIs linearly transformed with the change of radian. For example, for point E, the corresponding diffusion coefficient De is:
By transforming equation 11, we can obtain:
Substituting equation 14 into equation 13 yields:
According to
When De is represented by Dd, we can obtain:
Can be calculated according to the formula 16
So that the position of the color origin of replication is known. In other words, the method is adopted to carry out hue restoration on the focus, and can also carry out compensation and correction on the diffusion coefficient change problem caused by density transformation of the focus area, thereby further improving the accuracy of focus restoration.
Of course, in practical application, for convenience, the pushing-back mode can be adopted, namely, the mode of pushing backwards is used
Computing
Then the distance on the ray d from the center of the nucleus is
The hue value of the target point of (2) is assigned to the hue origin. When all the points to be restored are color restored, the restoration of the focal zone is completed. Specifically, the following formula can be derived using the same method:
Wherein
The distance from the intersection point of the ray e and the focal nucleus region to the nucleus center.
After the above derivation process is described in detail, specific steps involved in the embodiments of the present invention will be described below. Specifically, in steps S102 to S103, first, a first ray and a second ray that start from the core center and are tangent to the hue restoration region should be generated, and radians corresponding to polar angles of the two rays in a preset polar coordinate system with the core center as the origin, that is, a first radian corresponding to the first ray and a second radian corresponding to the second ray, should be determined. It should be noted that, the embodiment of the present invention is not limited to a specific polar coordinate system, and for example, the orientation of the polar axis and the positive direction of rotation can be set according to practical application requirements.
S104, determining a first intersection point between the edge of the focal nucleus region and the first ray, and determining a first distance between the nucleus center and the first intersection point.
Subsequently, in step S104, a first distance from a first intersection point of the first ray with an edge of the lesion core region to the core center needs to be determined. Of course, this step may also be performed using the second ray.
S105, searching a corresponding target point on a second ray by using the first distance, the first radian and the second radian as each hue restoration point in the hue restoration area, and replacing the hue value of the hue restoration point with the hue value of the target point to complete the hue restoration of the hue restoration area.
It can be understood that the hue restoration point is each pixel point in the color restoration region. In one possible case, finding a corresponding target point for each color restoration point in the color restoration area on the second ray by using the first distance, the first radian and the second radian may include:
step 11: generating a third ray which takes the core center as a starting point and passes through the hue complex origin, and determining a third radian of a polar angle corresponding to the third ray in a preset polar coordinate system which takes the core center as the origin;
step 12: determining a sixth intersection point between the edge of the focal nucleus region and the third ray, and determining a fourth distance between the nucleus center and the sixth intersection point;
step 13: determining a fifth distance between the hue restoration point and the kernel center, and determining a target point by using the first distance, the fourth distance, the fifth distance, the first radian, the second radian and the third radian according to the following modes:
wherein the content of the first and second substances,
representing the distance between the target point on the second ray and the center of the nucleus,
the first distance is represented as a function of,
it is indicated that the fourth distance is,
a fifth distance is indicated which is the distance,
represents the firstThe arc degree of the arc is that,
which represents the second arc of the circle,
representing a third radian.
Of course, if the step S104 is performed by using the second ray, the step of searching the target point, i.e., the steps 11 to 13, can also be performed on the first ray, and can be adjusted according to the actual requirement.
Further, in order to facilitate the observation of the color phase restoration process by the relevant personnel, the color phase restoration origin may also be selected according to a predetermined sequence, for example, according to the sequence from the inside to the outside of the lesion and from the first ray to the second ray, which may be set according to the actual application requirements.
In one possible case, finding a corresponding target point for each color restoration point in the color restoration area on the second ray by using the first distance, the first radian and the second radian may include:
step 21: and extracting a hue restoration origin in the hue restoration area according to a preset sequence, and searching a corresponding target point for the extracted hue restoration origin on a second ray by using the first distance, the first radian and the second radian.
Referring to fig. 3, fig. 3 is a schematic view of a hue restoration effect of a mononuclear lesion according to an embodiment of the present invention, wherein after the left half is restored, and before the right half is restored, it can be seen that the restored color can better represent the real color of the lesion, and the true color conforms to the diffusion rule of the lesion.
Based on the embodiment, when a binuclear focus near-infrared image is acquired, a mononuclear focus region including a focus core region and a color restoration region is extracted, and a first ray and a second ray which take the core center of the focus core region as a starting point and are tangent to the color restoration region are generated; then, the invention determines parameter information related to the first ray and the second ray, namely a first distance from the intersection point of the first ray and the edge of the lesion nuclear region to the nuclear center, and a first radian and a second radian of corresponding polar angles of the two rays in a preset polar coordinate system with the nuclear center as an origin; further, the invention searches a corresponding target point on the first ray or the second ray by using the first distance, the first radian and the second radian as each hue origin point in the hue restoration region, and replaces the hue value of the hue origin point by using the hue value of the target point, because the diffusion of the focus basically accords with the diffusion equation, and further can deduce based on the diffusion equation, for the hue origin point and the target point which theoretically have the same hue value, the distance between the hue origin point and the core center of the focus and the first distance, the first radian and the second radian form an incidence relation, so the hue restoration region in the mononuclear focus region is subjected to hue restoration by using the parameter information, accords with the basic rule of focus diffusion, and can effectively restore the mononuclear focus region.
Based on the above embodiment, the following describes the extraction process of the mononuclear lesion region and the generation process of the first ray and the second ray in detail. In one possible case, determining a mononuclear lesion region including a lesion core region and a hue restoration region in a binuclear lesion near-infrared image, and generating a first ray and a second ray starting from a core center of the lesion core region and tangent to the hue restoration region may include:
