Description

Technical Field

[0001] The present invention relates to data processing technologies, and in particular, to a radiotherapy data processing method, device, and medium. Background Art

[0002] In radiotherapy, radiation equipment is an indispensable tool in modern medical diagnosis and treatment. They use ionizing radiation such as X-rays and γ-rays to image the internal structure of the human body, helping doctors accurately judge the disease situation and formulate treatment plans. These devices are widely used in multiple medical fields such as radiology departments and interventional operating rooms, and are of great significance for the diagnosis and treatment of various diseases such as tumors, fractures, and cardiovascular diseases. Radiation equipment emits high-energy rays to penetrate human tissues and forms images based on the different absorption degrees of rays by different tissues, providing valuable visual information for doctors.

[0003] During the irradiation process of radiation equipment, in order to protect patients from unnecessary radiation damage, radiation shielding materials such as lead aprons are usually used for protection. However, in the prior art, the design of lead aprons often tends to be generalized, ignoring the impact of different body size differences on the protection effect. Since everyone's body shape, height, weight, and the dimensions of each body part are different, a general lead apron is often difficult to perfectly fit the body contour of each person, resulting in the situation that the lead apron may be too small or too large during actual use. When the lead apron is too small, some body areas may not be effectively shielded, increasing the risk of radiation exposure; while when the lead apron is too large, it not only affects the comfort and convenience of wearing, but also may reduce the protection effect due to imperfect shielding.

[0004] Therefore, how to customize and place corresponding shielding materials for the ray-exposed areas to improve the protection effect has become an urgent problem to be solved. Summary of the Invention

[0053] The beneficial effects of the present invention are as follows:

[0054] 1. By accurately excluding the worn protection area and the lesion irradiation area in the ray detection area, the present invention obtains the accurate range of the trunk exposure area. Further, by obtaining the intersection curve of the trunk exposure area and the lesion irradiation area and performing regularization processing or regular segmentation processing based on this, accurate protection areas are obtained. This meticulous processing method enables the placement of ray shielding objects to closely fit the areas that need to be protected, thereby avoiding excessive exposure of non-lesion parts to radiation, and significantly improving the accuracy and safety of ray protection. For medical staff and patients, this means less radiation risk and higher safety guarantee.

For the body type characteristics of different individuals, the present invention can dynamically generate a protection area that matches it and accurately select appropriate radiation shielding materials for placement. This innovation not only solves the problem of poor protection effect caused by the inappropriate size of general lead aprons, but also reduces the complexity and error of manual operation through an intelligent processing flow, improving the deployment efficiency of protection measures. For medical institutions, this means more efficient and accurate radiation protection services, which can better meet the personalized needs of patients.

[0056] 3. The present invention effectively integrates and optimizes the complex radiation data processing flow. Different area lead sheet placements are customized according to 2 different types of customization bases, so that a larger area can be covered without affecting the radiation detection of the lesion.

[0062] The technical solutions of the present invention will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0063] The present invention provides a radiotherapy data processing method, as Figure 1 shown, including steps S1 - S4:

[0064] S1. Exclude the worn protection area and the lesion irradiation area in the radiation detection area corresponding to the radiation device to obtain the trunk exposure area, and obtain the intersection of the trunk exposure area and the lesion irradiation area to obtain an intersection curve.

[0065] It should be noted that since the body types of different individuals are different, but the lead aprons are all prepared in advance, there will be some areas exposed to radiation. Therefore, our solution will determine the exposed areas of the torso to facilitate the subsequent placement and treatment of lead sheets.

[0066] Among them, the radiation device can be an X-ray device or a CT device. The radiation detection area is the irradiation area corresponding to the radiation device, the wearing protection area is the protection area corresponding to the lead apron, and the lesion irradiation area is the irradiation area corresponding to the lesion area, that is, the area where the radiation actually irradiates. The torso exposure area is the area of the human torso outside the lesion area that is exposed to radiation.

[0067] In actual operation, the radiation detection area is generally a regular area. Here, a rectangular area is taken as an example for easy understanding. The device can detect the ranges of the torso radiation area, the wearing protection area, and the lesion irradiation area. Through mathematical set operations, first calculate the union of the wearing protection area and the lesion irradiation area to obtain the exclusion area. Then subtract the exclusion area from the torso radiation area to determine the range of the torso exposure area.

[0068] After that, by analyzing the overlapping part of the torso exposure area and the lesion irradiation area, the intersection curve is obtained.

[0069] In some embodiments, (excluding the wearing protection area and the lesion irradiation area in the radiation detection area corresponding to the radiation device to obtain the torso exposure area) in step S1 includes S11 - S13:

[0070] S11, obtain the torso radiation area, the wearing protection area, and the lesion irradiation area in the radiation detection area corresponding to the radiation device.

[0071] It can be understood that the present invention will obtain the torso radiation area (the entire radiation area of the human torso), the wearing protection area (the protection area of the lead clothing in the radiation detection area), and the lesion irradiation area (the lesion area that actually needs to be detected) in the radiation detection area corresponding to the radiation device.

[0072] S12, obtain the exclusion area according to the union of the wearing protection area and the lesion irradiation area.

[0073] It can be understood that the ranges of the wearing protection area and the lesion irradiation area are integrated to obtain the exclusion area.

[0074] S13, obtain the torso exposure area based on the difference set between the torso radiation area and the exclusion area.

[0075] It can be understood that the torso exposure area is obtained based on the difference set between the torso radiation area and the exclusion area.

[0076] Through the above-mentioned embodiments, the present invention only performs the removal process on the removal area of the human body part in the ray detection area, and directly does not consider the remaining blank parts that have nothing to do with the human body, reducing the amount of data processing in the area.

[0077] S2. When it is determined that the intersection curve is not a closed curve, regularize the trunk exposure area to obtain a protection area.

[0078] It is not difficult to understand that by obtaining the intersection of the trunk exposure area and the lesion irradiation area to obtain an intersection curve, that is, the common boundary line of the two areas. If it is not a closed curve, it means that the corresponding trunk exposure area is independently distributed around the lesion irradiation area. For example, it is the exposed area of the lead clothing cuff. Subsequently, only this area needs to be regularized and lead sheets can be directly placed.

[0079] It should be noted that the lead clothing is made by uniformly mixing a certain proportion of lead powder in rubber and processed through a special process. Similarly, the lead sheet of the present invention is also a sheet-shaped ray shielding material made by the same technical means.

[0080] In some embodiments, step S2 (when it is determined that the intersection curve is not a closed curve, regularize the trunk exposure area to obtain a protection area) includes S21 - S23:

[0081] S21. When it is determined that the intersection curve is not a closed curve, perform coordinate processing on the ray detection area.

[0082] It is not difficult to understand that when it is determined that the intersection curve is not a closed curve, perform coordinate processing on the ray detection area. The coordinate processing can be to obtain the center point of the ray detection area as the coordinate origin to construct a coordinate system for coordinate processing. Subsequent coordinate processing can all adopt this method. See Figure 2 As shown, at this time, the intersection curve of the trunk exposure area and the lesion irradiation area is not a closed curve. For the convenience of understanding, a standard rectangular area is shown here.

[0083] S22. Based on the maximum abscissa and minimum abscissa of the trunk exposure area, construct a vertical independent line, and based on the maximum ordinate and minimum ordinate, construct a horizontal independent line.

[0084] It can be understood that by constructing a vertical independent line based on the maximum abscissa and minimum abscissa of the trunk exposure area, and a horizontal independent line based on the maximum ordinate and minimum ordinate, a subsequent independent protection area that wraps the trunk exposure area can be constructed.

[0085] S23. Generate a protection area corresponding to the trunk exposure area according to the vertical independent line and the horizontal independent line.

[0086] It is not difficult to understand that, based on the vertical independent lines and the horizontal independent lines, a protection area corresponding to the trunk exposure area is generated.

[0087] S3. When it is determined that the intersection curve is a closed curve, the trunk exposure area is regularly segmented based on the lesion irradiation area to obtain multiple protection areas.

[0088] It can be understood that when it is determined that the intersection curve is a closed curve, it means that there is a lesion irradiation area inside the boundary line of the trunk exposure area. Therefore, at this time, the trunk exposure area cannot be directly regularized and lead sheets cannot be placed, which will result in complete occlusion of the lesion area. See Figure 3 As shown, at this time, the intersection curve between the trunk exposure area and the lesion irradiation area is a closed curve. For the convenience of understanding, a standard rectangular area is shown here.

[0089] In some embodiments, step S3 (when it is determined that the intersection curve is a closed curve, the trunk exposure area is regularly segmented based on the lesion irradiation area to obtain multiple protection areas) includes S31 - S35:

[0090] S31. When it is determined that the intersection curve is a closed curve, the ray detection area is coordinate-processed.

[0091] It can be understood that when it is determined that the intersection curve is a closed curve, the ray detection area can be coordinate-processed by obtaining the center point of the ray detection area as the coordinate origin for coordinate-processing.

[0092] S32. Based on the maximum abscissa and the minimum abscissa of the trunk exposure area, a vertical regular line is constructed, and based on the maximum ordinate and the minimum ordinate, a horizontal regular line is constructed. According to the vertical regular line and the horizontal regular line, a trunk regular area is generated.

[0093] Similarly, since the shapes of the lesion area and the trunk exposure area are irregular and random, but the lead sheets are pre-set, the present invention will subsequently regularize the trunk exposure area and the lesion irradiation area.

[0094] It can be understood that the server constructs a vertical regular line based on the maximum abscissa and the minimum abscissa of the trunk exposure area, and constructs a horizontal regular line based on the maximum ordinate and the minimum ordinate. According to the vertical regular line and the horizontal regular line, a trunk regular area is generated.

[0095] S33. Based on the maximum abscissa and the minimum abscissa of the lesion irradiation area, a vertical irradiation line is constructed, and based on the maximum ordinate and the minimum ordinate, a horizontal irradiation line is constructed. According to the vertical irradiation line and the horizontal irradiation line, a lesion regular area is generated.

[0096] Similarly, in accordance with the same principle as in step S32, vertical irradiation lines will be constructed based on the maximum and minimum abscissas of the lesion irradiation area, and horizontal irradiation lines will be constructed based on the maximum and minimum ordinates. According to the vertical and horizontal irradiation lines, a regular lesion area will be generated.

[0097] S34. Remove the regular lesion area from the regular trunk area to obtain a regular exposure area.

[0098] It can be understood that by removing the regular lesion area from the regular trunk area to obtain a regular exposure area, only the regular exposure area needs to be successively spliced and placed with lead sheets in the follow-up, thereby reducing the impact of rays on the human body.

[0099] S35. Extend the vertical irradiation line until it intersects with the regular trunk area to obtain a vertical division line. Based on the vertical division line, perform segmentation processing on the regular exposure area to obtain multiple protection areas.

[0100] It should be noted that, for example Figure 3 , because the lesion irradiation area is inside the trunk exposure area, it is impossible to directly perform regularization processing and place lead sheets. Therefore, the trunk exposure area will be regionally segmented. By extending the vertical irradiation lines on both sides of the regular lesion area, the area will be divided into multiple regions. Subsequently, appropriate lead sheets will be selected and placed according to each regular region.

[0101] It can be understood that the server will extend the vertical irradiation line until it intersects with the regular trunk area to obtain a vertical division line. Based on the vertical division line, perform segmentation processing on the regular exposure area to obtain multiple protection areas.

[0102] S4. Select the radiation shielding objects for each protection area, and select the alignment points of the protection area. Based on the alignment points, control the placement device to place the radiation shielding objects at the protection areas.

[0103] Among them, the radiation shielding object is an object for shielding rays, such as a lead sheet, and the alignment point is the placement point for subsequently aligning the radiation shielding object with the protection area.

[0104] It can be understood that the server will select the radiation shielding objects for each protection area, and select the alignment points of the protection area. Based on the alignment points, control the placement device to place the radiation shielding objects at the protection areas.

[0105] In some embodiments, step S4 (select the radiation shielding objects for each protection area, and select the alignment points of the protection area. Based on the alignment points, control the placement device to place the radiation shielding objects at the protection areas) includes S41 - S43:

[0106] S41. Retrieve the protection sizes of each protection area and the standard sizes of the standard shielding objects, and determine the standard shielding objects whose standard sizes are greater than or equal to the protection sizes as the radiation shielding objects.

[0107] It is understandable that the protection dimensions of each protection area and the standard dimensions of the standard shielding are retrieved. The dimensions can be the length and width dimensions of the area. Since the lead sheet is required to cover the protection area, it is necessary to select a standard shielding with a standard dimension greater than or equal to the protection dimension. Then, this standard shielding is used as the ray shielding.

[0108] It is not difficult to understand that there is always a situation where no matter how the corresponding dimensions are selected, it is always impossible to meet the requirements. Generally, the area is relatively large, that is, the length direction is too long to be covered by a single lead sheet. Therefore, the present invention will select multiple lead sheets for splicing.

[0109] Based on the above embodiments, it further includes:

[0110] If there is no standard dimension greater than or equal to the protection dimension, retrieve the protection width and protection length in the protection dimension, and the standard width and standard length corresponding to the standard dimension.

[0111] It is understandable that if there is no standard dimension greater than or equal to the protection dimension, retrieve the protection width and protection length in the protection dimension, and the standard width and standard length corresponding to the standard dimension. That is, no matter how it is selected, it is always impossible to select a single lead sheet to completely cover the protection area. Therefore, multiple lead sheets will be selected for splicing and covering later.

[0112] Select a standard shielding with a standard width greater than or equal to the protection width as the shielding to be selected, obtain the dimensions of each shielding to be selected as statistical dimensions, and count the shields to be selected with each of the statistical dimensions to obtain a splicing shielding set corresponding to each statistical dimension.

[0113] It is understandable that a standard shielding with a standard width greater than or equal to the protection width is selected as the shielding to be selected, and a lead sheet that can completely cover the width is selected as the shielding to be selected. Subsequently, the dimensions of each shielding to be selected are obtained as statistical dimensions, and the shields to be selected are classified according to the statistical dimensions to obtain a splicing shielding set corresponding to each statistical dimension.

[0114] Based on the number of shields to be selected in the splicing shielding set, perform a descending order sorting on the splicing shielding set to obtain a splicing set sequence.

[0115] It is not difficult to understand that the splicing shielding set will be sorted in descending order according to the number, and the set with the largest number of splices will be placed at the front, thereby obtaining a splicing set sequence.

[0116] Select the to-be-selected shields in each splicing shield set in the splicing set sequence in turn as the selected shields, and count the standard length of the selected shields to obtain the splicing length. When the splicing length is greater than or equal to the protection length, use the corresponding selected shields as the ray shields for the corresponding protection areas.

[0117] It can be understood that subsequently, the to-be-selected shields in each splicing shield set in the splicing set sequence will be selected in turn as the selected shields, that is, select 1 to-be-selected shield from the first splicing shield set, and then select 1 to-be-selected shield from the second splicing shield set, and count the standard length of the selected shields to obtain the splicing length. When the splicing length is greater than or equal to the protection length, use the corresponding selected shields as the ray shields for the corresponding protection areas.

[0118] Through the above implementation manner, the present invention can preferentially select those with a larger quantity for preferential splicing, which is convenient for other personnel to select appropriate-sized lead sheets for placement and processing later. By strictly selecting shields in sequence according to the splicing set sequence and determining the final shield combination with the splicing length reaching or exceeding the protection length as the standard, it is ensured that the protection area can be completely covered, and the risk of the non-lesion parts of the patient being exposed to radiation is minimized to provide accurate and reliable protection for the patient, strongly guaranteeing the safety during the medical process.

[0119] S42. When it is determined that the intersection curve is not a closed curve, use the corresponding protection area as the central protection area, select the central alignment point of the central protection area, and based on the central alignment point, control the placement device to place the ray shield at the central protection area.

[0120] It can be understood that when it is determined that the intersection curve is not a closed curve, it means that this is an independent protection area, generally distributed around the lead apron at positions such as the arms. At this time, directly cover this area with lead sheets.

[0121] It can be understood that when it is determined that the intersection curve is not a closed curve, use the corresponding protection area as the central protection area, select the central alignment point of the central protection area, and based on the central alignment point, control the placement device to place the ray shield at the central protection area.

[0122] In some embodiments, (when it is determined that the intersection curve is not a closed curve, use the corresponding protection area as the central protection area, select the central alignment point of the central protection area, and based on the central alignment point, control the placement device to place the ray shield at the central protection area) in step S42 includes S421 - S422:

[0123] S421. When it is determined that the intersection curve is not a closed curve, use the corresponding protection area as the central protection area, and obtain the regional center point of the central protection area as the central alignment point.

[0124] It can be understood that when it is determined that the intersection curve is not a closed curve, the corresponding protection area is used as the central protection area, and the area center point of the central protection area is obtained as the central alignment point.

[0125] S422, obtain the center point of the ray shield as the shielding center point, and control the placement device to align the shielding center point with the central alignment point.

[0126] It is not difficult to understand that at this time, the center point of the ray shield is directly obtained as the shielding center point, and then the placement device is controlled to align the shielding center point with the central alignment point, so as to align the center point of the lead sheet with the center point of the central protection area, so that the lead sheet can cover the central protection area. Among them, the placement device can be a robotic arm for placing the lead sheet.

[0127] It should be noted that since the shielding center point of the ray shield is aligned with the area center point of the central protection area to complete the placement and block the rays in the area, but since the previously selected standard size is greater than or equal to the protection size, there will be a situation where the ray shield will block the lesion irradiation area. Therefore, in this case, our solution will continue to divide the shielding area of the ray shield, and then place the lead sheet selected for the divided protection area.

[0128] Therefore, on the basis of the above embodiments, it further includes A1 - A3:

[0129] A1, obtain the shielding area of the ray shield, and obtain the intersection of the shielding area and the lesion irradiation area to obtain an interference area.

[0130] It is not difficult to understand that the server will obtain the shielding area of the ray shield. For example, the shielding area of the lead sheet, and then determine the intersection of the shielding area and the lesion irradiation area to obtain an interference area, that is, the area where the lesion irradiation area is blocked and interfered by the lead sheet.

[0131] A2, if there is an interference area, perform coordinate processing on the ray detection area, and obtain the maximum abscissa and minimum abscissa in the interference area to construct a vertical division line, and the maximum ordinate and minimum ordinate to construct a horizontal division line.

[0132] Therefore, if there is an interference area, for example, when the middle lesion irradiation area is circular, perform coordinate processing on the ray detection area, and obtain the maximum abscissa and minimum abscissa in the interference area to construct a vertical division line, and the maximum ordinate and minimum ordinate to construct a horizontal division line.

[0133] The shielding area is segmented by 4 dividing lines. Since the interference area itself is the intersection of the lead sheet and the lesion irradiation area, the dividing lines themselves coincide with the area lines of the shielding area, and the other dividing lines are used to segment the shielding area.

[0134] A3. The shielding area is segmented according to the vertical dividing line and the horizontal dividing line to obtain multiple segmented areas. The segmented area with the interference area is used as the non-protection area, and the remaining segmented areas are used as the segmented protection areas.

[0135] It can be understood that the shielding area is segmented according to the vertical dividing line and the horizontal dividing line to obtain multiple segmented areas. The segmented area with the interference area is used as the non-protection area, and the remaining segmented areas are used as the segmented protection areas.

[0136] Therefore, in the follow-up, only lead sheets with the same size or larger than the segmented protection areas need to be selected and placed, while the non-protection areas that are blocked are not selected for lead sheet shielding. Thus, while providing good protection for the areas of the human body exposed to the rays, it will not affect the lesion irradiation area.

[0137] S43. When it is determined that the intersection curve is a closed curve, the corresponding protection area is used as the vertex protection area, the vertex alignment points of the vertex protection area are selected, and based on the vertex alignment points, the ray shielding object is placed at the vertex protection area by controlling the placement device.

[0138] In some embodiments, (when it is determined that the intersection curve is a closed curve, the corresponding protection area is used as the vertex protection area, the vertex alignment points of the vertex protection area are selected, and based on the vertex alignment points, the ray shielding object is placed at the vertex protection area) in step S43 includes S431 - S434:

[0139] S431. When it is determined that the intersection curve is a closed curve, the corresponding protection area is used as the vertex protection area, the common side between the vertex protection area and the lesion regular area is obtained, and the area line where the common side is located in the vertex protection area is determined as the selection line.

[0140] It should be noted that when the intersection curve is a closed curve, it is impossible to place lead sheets on the entire exposed area because it will block the lesion irradiation area. Therefore, in our invention, the protection area after regular segmentation is used as the vertex protection area, the common side between the vertex protection area and the lesion regular area is obtained, and the area line where the common side is located in the vertex protection area is determined as the selection line.

[0141] In the above way, the selection line is determined, and subsequent alignment will be based on the vertices on the selection line, so as not to affect the lesion irradiation area.

[0142] S432. Take the two vertices on the selection line as the selection apex points, and obtain the coordinates of the center points corresponding to each trunk activity area as the activity coordinate points.

[0143] It should be noted that generally, the intersection curve is a closed curve, that is, the lesion regular area is located inside the boundary line of the trunk exposure area. At this time, it is generally located in body parts, such as the collar and other positions. At this time, since the lead sheet is generally greater than or equal to the protection area, it will have an impact on the head and limbs. For example, the excess part will affect the trunk activity areas such as the limbs and the head, affecting the activities. Among them, the trunk activity areas are the activity areas corresponding to the limbs and the head.

[0144] Therefore, the present invention takes the two vertices on the selection line as the selection apex points, and obtains the coordinates of the center points corresponding to each trunk activity area as the activity coordinate points.

[0145] S433. Obtain the coordinates of the selection apex points as the apex coordinate points, and calculate according to the activity coordinate points and the apex coordinate points to obtain multiple activity distances corresponding to each apex coordinate point.

[0146] It can be understood that obtaining the coordinates of the selection apex points as the apex coordinate points, calculating according to the activity coordinate points and the apex coordinate points, and obtaining multiple activity distances corresponding to each apex coordinate point, will select the vertex with the shortest activity distance among the two vertices as the alignment point, so that when the subsequent lead sheet is aligned and placed, it will not affect the activity area, such as restricting the head movement of the person.

[0147] S434. Select the apex coordinate point corresponding to the minimum activity distance as the apex alignment point, and control the placement device to align the corresponding vertex of the ray shielding object with the apex alignment point.

[0148] It can be understood that the server will select the apex coordinate point corresponding to the minimum activity distance as the apex alignment point, and control the placement device to align the corresponding vertex of the ray shielding object with the apex alignment point. That is, select the vertex that is most likely to affect the activity area as the apex alignment point, and then align and place the lead sheet vertices, so that the excess extension direction of the lead sheet is the body part and will not affect the normal activities of the trunk activity area.
