[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] According to an embodiment of this application, a method for generating an auxiliary abdominal and pelvic radiotherapy device is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown here.

[0030] Figure 1 This is a flowchart of a method for generating an auxiliary abdominal and pelvic radiotherapy device according to an embodiment of this application, such as... Figure 1 As shown, the method may include the following steps.

[0031] Step S101: With the radiotherapy subject on the initial foaming device, a suspended mold that matches the body shape of the radiotherapy subject is deployed in the deployment area of ​​the initial foaming device.

[0032] In the technical solution provided by step S101 of this application, the deployment area can be used to represent the area of ​​the abdominopelvic region of the radiotherapy subject mapped onto the initial foaming device. For example, the deployment area can be the area where the target center of the abdominopelvic region is located, mapped onto the position of the foaming adhesive.

[0033] In this embodiment, the term "radiotherapy subject" can refer to an individual requiring assisted abdominal and pelvic radiotherapy. For example, the radiotherapy subject can be a patient, which may include young patients, middle-aged patients, and elderly patients, etc. This is merely an example and not a specific limitation.

[0034] In this embodiment, the body type of the radiotherapy subject can be reflected by the subject's height and weight. For example, if a young patient is 180cm tall and weighs 130kg, then the young patient's body type can be described as large, which can be represented by L. Alternatively, if a middle-aged patient is 172cm tall and weighs 115kg, then the middle-aged patient's body type can be described as medium, which can be represented by M. This is merely an example and not a specific limitation.

[0035] In this embodiment, the initial foaming device can be an unmolded foam substrate. For example, the foam substrate can also be simply referred to as foam.

[0036] In this embodiment, the aforementioned suspended mold can be used to generate a suspended area from the deployed initial foaming device during the molding process, and the suspended mold is a detachable mold. For example, the aforementioned suspended mold can also be referred to as any of the following: a pelvic suspended area mold and a suspended area forming mold, etc.

[0037] In this embodiment, with the radiotherapy subject on the initial foaming device, a suspended mold conforming to the subject's body shape is deployed in the deployment area of ​​the initial foaming device. Optionally, in this embodiment, if the radiotherapy subject is on the initial foaming device, a suspended mold conforming to the subject's body shape is selected from a set of suspended molds. The selected suspended mold is then deployed in the deployment area of ​​the initial foaming device; for example, a suspended mold conforming to the patient's body shape for the abdominal and pelvic region is deployed in the deployment area of ​​the uncured foam.

[0038] Step S102: The deployed initial foaming device is subjected to molding treatment to obtain a molded foaming device.

[0039] In the technical solution provided by step S102 of this application, the molding process may include expansion and curing. The expansion can be accomplished by a foaming reaction of the foaming adhesive, and the curing can be accomplished by locking the shape of the foaming adhesive after the foaming reaction has ended.

[0040] In this embodiment, the molding foaming device described above can be used to generate an auxiliary abdominal and pelvic radiotherapy device. For example, the molding foaming device can be an expanded and cured foam.

[0041] In this embodiment, after the radiotherapy subject is placed on the initial foaming device, a suspended mold that meets the body shape of the radiotherapy subject is deployed in the deployment area of ​​the initial foaming device, and the deployed initial foaming device is subjected to molding processing to obtain a molded foaming device, thereby achieving the purpose of generating a molded foaming device through molding processing.

[0042] Optionally, the deployed initial foaming device can be expanded to obtain an expanded foaming device. For example, the deployed initial foaming device can be moved to a different position, and the moved initial foaming device can be expanded to obtain an expanded foaming device.

[0043] Optionally, after obtaining the expansion foaming device, a molding foaming device can be generated using the expansion foaming device. For example, the expansion foaming device can be adjusted, and the adjusted expansion foaming device can be cured to obtain the molding foaming device.

[0044] Step S103: Remove the suspended mold from the molding foaming device to obtain an auxiliary abdominal and pelvic radiotherapy device suitable for radiotherapy patients.

[0045] In the technical solution provided in step S103 of this application, the aforementioned auxiliary abdominal and pelvic radiotherapy device can be used to assist in radiotherapy for the radiotherapy subject. For example, the aforementioned auxiliary abdominal and pelvic radiotherapy device can be a fixation device for assisted abdominal and pelvic radiotherapy in a suspended position.

[0046] In this embodiment, after the initial foaming device is molded to obtain a molded foaming device, the suspended mold deployed in the deployment area is removed from the molded foaming device. The molded foaming device after removal is then designated as an auxiliary abdominal and pelvic radiotherapy device. Alternatively, the molded foaming device after removal is adjusted, and the adjusted molded foaming device is designated as an auxiliary abdominal and pelvic radiotherapy device, thereby achieving the goal of generating an auxiliary abdominal and pelvic radiotherapy device suitable for radiotherapy patients.

[0047] In steps S101 to S103 of this application, when the radiotherapy subject is on the initial foaming device, a suspended mold conforming to the body shape of the radiotherapy subject is deployed in the deployment area of ​​the initial foaming device; the deployed initial foaming device is then molded to obtain a molded foaming device; the suspended mold is removed from the molded foaming device to obtain an auxiliary abdominal and pelvic radiotherapy device suitable for the radiotherapy subject. Because in the process of generating the auxiliary abdominal and pelvic radiotherapy device in this embodiment, if the radiotherapy subject is on the initial foaming device, a suspended mold conforming to the body shape of the radiotherapy subject is deployed in the deployment area, the deployed initial foaming device is molded to obtain a molded foaming device, and then the suspended mold deployed in the deployment area is removed from the molded foaming device to obtain the auxiliary abdominal and pelvic radiotherapy device, the risk of mis-radiation of areas of the radiotherapy subject that do not require radiotherapy is reduced, thereby solving the technical problem of low safety during radiotherapy and achieving the technical effect of improving the safety of radiotherapy.

[0048] The method described in this embodiment will be further described below.

[0049] As an optional embodiment, step S102 involves molding the deployed initial foaming device to obtain a molded foaming device, including: expanding the deployed initial foaming device to obtain an expanded foaming device; and curing the expanded foaming device to obtain a cured foaming device.

[0050] In this embodiment, after the radiotherapy subject is placed on the initial foaming device, a suspended mold conforming to the body shape of the radiotherapy subject is deployed in the deployment area of ​​the initial foaming device, and then the deployed initial foaming device is expanded to obtain an expanded foaming device. Optionally, the deployed initial foaming device undergoes a foaming reaction, and is expanded to obtain an expanded foaming device.

[0051] For example, by allowing uncured expanding foam to undergo a foaming reaction, the foam begins to slowly expand and conform to the patient's contours, resulting in expanded expanding foam. During the foaming process, the patient's position is kept stable, avoiding body movement, rotation, or tilting, until the expanding foam completely covers the chest, back, lumbosacral region, both hips, and upper thighs, forming upward-protruding edge restraints on both sides.

[0052] In this embodiment, after expanding the deployed initial foaming device to obtain an expanded foaming device, the expanded foaming device is then cured to obtain a cured foaming device. Optionally, the expanded foaming device can be cut according to the contour of the radiotherapy subject, and the cut expanded foaming device can be cured to obtain a shaped foaming device. This achieves the goal of generating a shaped foaming device through a molding process, thereby realizing the technical effect of improving the applicability of the shaped foaming device to the radiotherapy subject.

[0053] For example, the expanded foam can be cut according to the patient's contours, and the cut foam can be cured to obtain cured foam.

[0054] The following section further describes the steps of curing the expansion foaming device described above in this embodiment to obtain a cured foaming device.

[0055] As an optional embodiment, the expansion foaming device is cured to obtain a cured foaming device, including: determining the degree of expansion reached by the expansion foaming device after expansion; and curing the expansion foaming device in response to the degree of expansion being within the expansion range to obtain a cured foaming device.

[0056] In this embodiment, the degree of expansion can be represented by an expansion ratio, which is the volume expansion factor. For example, the volume expansion factor can be any multiple between 10 and 20 times. The value here is only for illustrative purposes and is not specifically limited.

[0057] In this embodiment, after expanding the deployed initial foaming device to obtain an expanded foaming device, the degree of expansion achieved by the expanded foaming device is determined. Optionally, the volume of the expanded foaming device can be obtained by performing volume detection. The degree of expansion is determined by the volume multiple of the expanded foaming device to the volume of the initial foaming device.

[0058] In this embodiment, after determining the degree of expansion achieved by the expanding foaming device, in response to the degree of expansion being within the expansion range, the expanding foaming device is cured to obtain a cured foaming device. Optionally, the degree of expansion is compared with the expansion range. If the degree of expansion is found to be within the expansion range, the expanding foaming device is directly cured to obtain a molded foaming device. This achieves the goal of generating a molded foaming device through molding processing, thereby realizing the technical effect of improving the applicability of the molded foaming device to radiotherapy subjects.

[0059] For example, compare the expansion ratio with the expansion ratio range. If the expansion ratio is within the expansion ratio range, then directly cure the expanded foam to obtain the cured foam.

[0060] Optionally, the degree of expansion and the expansion range can be compared. If the degree of expansion is found to be outside the expansion range, the expansion foam device is cut according to the contour of the radiotherapy object, and the cut expansion foam device is cured to obtain a molded foam device.

[0061] For example, the expansion ratio is compared with the expansion ratio range. If the expansion ratio is found to be outside the expansion ratio range, the expanded foam is cut according to the patient's contour, and the cut foam is cured to obtain the cured foam.

[0062] The following describes in further detail the steps of removing the suspended mold from the molding foaming device to obtain an auxiliary abdominal and pelvic radiotherapy device suitable for radiotherapy patients in this embodiment.

[0063] As an optional embodiment, step S103, removing the suspended mold from the molding foaming device to obtain an auxiliary abdominal and pelvic radiotherapy device suitable for the radiotherapy subject, includes: identifying the suspended area generated by the removed suspended mold during the molding process from the removed molding foaming device; and determining the auxiliary abdominal and pelvic radiotherapy device based on the suspended area and the removed molding foaming device.

[0064] In this embodiment, the range of the aforementioned suspended region may be smaller than the range of the deployment area. For example, the aforementioned suspended region may be a suspended cavity structure.

[0065] In this embodiment, after the initial foaming device is molded to obtain a molded foaming device, the suspended area generated by the removed suspended mold during the molding process is identified from the removed molded foaming device. Optionally, region identification can be performed on the cured foam after the mold of the pelvic suspended area is removed to obtain the suspended area generated by the mold of the removed pelvic suspended area during the molding process.

[0066] In this embodiment, after identifying the suspended area generated by the removed suspended mold during the molding process from the removed molding foaming device, an auxiliary abdominal and pelvic radiotherapy device is determined based on the suspended area and the removed molding foaming device. Optionally, if the suspended area matches the suspended area template, the removed molding foaming device is determined as an auxiliary abdominal and pelvic radiotherapy device. Alternatively, if the suspended area fails to match the suspended area template, the removed molding foaming device is adjusted, and the adjusted molding foaming device is determined as an auxiliary abdominal and pelvic radiotherapy device. This achieves the goal of generating an auxiliary abdominal and pelvic radiotherapy device suitable for radiotherapy patients, thereby improving the usability of the auxiliary abdominal and pelvic radiotherapy device.

[0067] The steps for determining the auxiliary abdominal and pelvic radiotherapy device based on the suspended region and the removed molded foam device in this embodiment will be further described below.

[0068] As an optional embodiment, determining an auxiliary abdominopelvic radiotherapy device based on the suspended region and the removed molded foam device includes: matching the suspended region with a suspended region template to obtain a matching result; and determining the auxiliary abdominopelvic radiotherapy device based on the matching result and the molded foam device.

[0069] In this embodiment, the above-mentioned suspended area template can be a template for generating a suspended area reference for a suspended mold.

[0070] In this embodiment, after identifying the suspended area generated by the removed suspended mold during the molding process from the removed molding foaming device, the suspended area is matched with the suspended area template to obtain a matching result. Optionally, the similarity between the suspended area and the suspended area template is determined. Based on the above similarity, the suspended area and the suspended area template are matched to obtain a matching result.

[0071] For example, if the similarity is greater than or equal to the similarity threshold, the suspended region is matched with the suspended region template, and the matching result is "suspended region to suspended region template match successfully". If the similarity is less than the similarity threshold, the suspended region is matched with the suspended region template, and the matching result is "suspended region to suspended region template match fails".

[0072] In this embodiment, after matching the suspended area with the suspended area template to obtain the matching result, an auxiliary abdominal and pelvic radiotherapy device is determined based on the matching result and the molding foam device. Optionally, according to the above matching result, the removed molding foam device is determined as the auxiliary abdominal and pelvic radiotherapy device. Alternatively, according to the above matching result, the removed molding foam device is adjusted, and the adjusted molding foam device is determined as the auxiliary abdominal and pelvic radiotherapy device. This achieves the goal of generating an auxiliary abdominal and pelvic radiotherapy device suitable for radiotherapy subjects, thereby realizing the technical effect of improving the usability of the auxiliary abdominal and pelvic radiotherapy device.

[0073] The steps for determining the auxiliary abdominal and pelvic radiotherapy device based on the matching results and the molding foaming device in this embodiment will be further described below.

[0074] As an optional embodiment, determining an auxiliary abdominopelvic radiotherapy device based on the matching result and the molded foam device includes: in response to the matching result indicating that the suspended region and the suspended region template are successfully matched, determining the removed molded foam device as an auxiliary abdominopelvic radiotherapy device; in response to the matching result indicating that the suspended region and the suspended region template are not matched, adjusting the removed molded foam device, and determining the adjusted molded foam device as an auxiliary abdominopelvic radiotherapy device.

[0075] In this embodiment, after matching the suspended area with the suspended area template and obtaining the matching result, if the matching result is that the suspended area and the suspended area template are successfully matched, the removed molding foaming device is identified as an auxiliary abdominal and pelvic radiotherapy device.

[0076] For example, if the above matching result is that the suspended area matches the suspended area template successfully, the cured foam after removing the mold of the suspended area of ​​the abdominal and pelvic region can be used as a fixation device for the suspended position of the abdominal and pelvic region during radiotherapy. This achieves the goal of generating a fixation device suitable for the patient's suspended position during radiotherapy of the abdominal and pelvic region, thereby achieving the technical effect of improving the usability of the above fixation device.

[0077] In other words, the foam mixing reaction is initiated, and the foam begins to slowly expand and conform to the contours of the human body. During the foaming process, the patient's position is kept stable, avoiding movement, rotation, or tilting, until the foam completely covers the chest, back, lumbosacral region, both hips, and upper thighs, forming upward-protruding edge restraints on both sides. After the foam substrate is completely cured and structurally stable, the mold for the suspended area is removed. If a continuous, smooth, and precisely sized downward-concave suspended cavity is formed in the cured and stabilized foam substrate, then the cured and stabilized foam substrate serves as a fixation device for the suspended position during abdominal and pelvic radiotherapy.

[0078] In this embodiment, after matching the suspended region with the suspended region template and obtaining the matching result, in response to the matching result being that the suspended region and the suspended region template failed to match, the removed molding foaming device is adjusted, and the adjusted molding foaming device is determined as an auxiliary abdominal and pelvic radiotherapy device.

[0079] For example, if the above matching result is that the suspended area fails to match the suspended area template, the solidified foam after removing the mold of the suspended area of ​​the abdominal and pelvic region is adjusted, and the adjusted and solidified foam is used as a fixation device for the suspended position of the abdominal and pelvic region during radiotherapy. This achieves the goal of generating a fixation device suitable for the patient's suspended position during radiotherapy of the abdominal and pelvic region, thereby achieving the technical effect of improving the usability of the above fixation device.

[0080] The method for generating the above-described auxiliary abdominal and pelvic radiotherapy device in this embodiment will be further described below.

[0081] As an optional embodiment, the method further includes: performing position verification on the auxiliary abdominal and pelvic radiotherapy device for the radiotherapy subject and obtaining verification results; in response to the verification results indicating that the positional error between the auxiliary abdominal and pelvic radiotherapy device and the radiotherapy subject is within the positional error range, performing auxiliary radiotherapy on the radiotherapy subject using the auxiliary abdominal and pelvic radiotherapy device.

[0082] In this embodiment, the verification results can be used to indicate whether the positional error between the auxiliary abdominal and pelvic radiotherapy device and the patient is within the positional error range. For example, the verification results can indicate that the positional error between the fixation device for the suspended position in auxiliary abdominal and pelvic radiotherapy and the patient is within the positional error range, or that the positional error between the fixation device for the suspended position in auxiliary abdominal and pelvic radiotherapy and the patient is outside the positional error range.

[0083] In this embodiment, the position of the auxiliary abdominal and pelvic radiotherapy device for the patient undergoing radiotherapy is verified, and the verification results are obtained. Optionally, the position of the patient and the fixation device in the suspended position of the auxiliary abdominal and pelvic radiotherapy is measured by laser positioning line and cone beam computed tomography (CBCT), which can obtain the positional error between the fixation device and the patient in the suspended position of the auxiliary abdominal and pelvic radiotherapy. The positional error and its range are verified to determine whether the positional error is within the range of positional error.

[0084] In this embodiment, after verifying the position of the auxiliary abdominal and pelvic radiotherapy device for the patient and obtaining the verification result, if the verification result indicates that the positional error between the auxiliary abdominal and pelvic radiotherapy device and the patient is within the positional error range, then the auxiliary abdominal and pelvic radiotherapy device is used to perform auxiliary radiotherapy on the patient. This achieves the goal of using a fixation device for the suspended position of the auxiliary abdominal and pelvic radiotherapy to perform auxiliary radiotherapy on the patient, thereby achieving the technical effect of improving the safety of radiotherapy for the patient.

[0085] Optionally, if the above-mentioned positional error is verified to be within the positional error range, after starting the radiotherapy equipment for radiotherapy to the patient, the patient is fixed using a fixation device for the suspended position of the abdominopelvic radiotherapy, and the radiotherapy equipment is used to perform radiotherapy on the fixed areas of the patient. In this case, the patient's lower abdomen is naturally suspended due to the suspended cavity structure and does not contact any supporting structure, and normal tissues such as the small intestine are passively moved out of the irradiation field under the action of gravity.

[0086] For example, before adjuvant radiotherapy, the foam suspension fixation device is placed in the same position on the radiotherapy bed. The patient lies accurately in the support area according to the marked lines and the outline of the foam, with the abdomen and pelvis naturally falling into the suspension area, keeping the abdomen free from contact and pressure. The position is verified using laser positioning lines and CBCT. If the positioning error is verified to be within the allowable range, radiotherapy is initiated. Each radiotherapy session maintains the same position, the same support, and the same suspension state to ensure treatment repeatability and dosage accuracy.

[0087] In this embodiment of the application, during the generation of the auxiliary abdominal and pelvic radiotherapy device, if the radiotherapy subject is on the initial foaming device, a suspended mold that meets the body shape of the radiotherapy subject is deployed in the deployment area. The deployed initial foaming device is then shaped to obtain a shaped foaming device. Then, the suspended mold deployed in the deployment area is removed from the shaped foaming device to obtain the auxiliary abdominal and pelvic radiotherapy device. This achieves the goal of reducing the risk of mis-radiotherapy to areas of the radiotherapy subject that do not require radiotherapy, thereby solving the technical problem of low safety in radiotherapy for radiotherapy subjects and achieving the technical effect of improving the safety of radiotherapy for radiotherapy subjects.

[0088] The technical solutions of the embodiments of this application will be illustrated below with reference to preferred embodiments.

[0089] Currently, in the radiotherapy of abdominal and pelvic tumors, abdominal suspension frames or simple foam adhesive are often used to fix the radiotherapy patient.

[0090] However, the aforementioned fixation devices have low applicability to different radiotherapy subjects, which may lead to erroneous radiotherapy to areas of the subject that do not require radiotherapy, resulting in low safety of radiotherapy.

[0091] To address the aforementioned technical problems, this application proposes a method for generating an auxiliary abdominal and pelvic radiotherapy device. During the generation of the auxiliary abdominal and pelvic radiotherapy device, if the radiotherapy subject is on an initial foaming device, a suspended mold conforming to the body shape of the radiotherapy subject is deployed in the deployment area. The deployed initial foaming device is then molded to obtain a molded foaming device. Next, the suspended mold deployed in the deployment area is removed from the molded foaming device to obtain the auxiliary abdominal and pelvic radiotherapy device. This reduces the risk of accidental radiotherapy to areas of the radiotherapy subject that do not require radiotherapy, thus solving the technical problem of low safety during radiotherapy and achieving the technical effect of improving the safety of radiotherapy for the radiotherapy subject.

[0092] In this embodiment, a fixation device for assisting in the suspended position during abdominoplasty can be generated by executing a method for generating such a device. For example, Figure 2This is a flowchart illustrating a method for generating a fixation device for assisting in a suspended position during abdominal and pelvic radiotherapy, according to an embodiment of this application. Figure 2 As shown, the method may include the following steps.

[0093] Step S201: Perform preparation operations on the fixation device for generating the auxiliary abdominal and pelvic radiotherapy suspended position.

[0094] In the technical solution provided by step S201 of this application, during the preparation stage, the radiotherapy positioning bed is adjusted to a horizontal position and debris on the bed surface is removed. Based on the patient's height and the location of the tumor in the abdominal and pelvic region, a medical two-component polyurethane foam substrate and a suspended area molding mold (e.g., a removable foam pad) are placed centrally on the positioning bed. For example, the suspended area molding mold is placed at the position of the foam substrate, mapped to the center of the target area in the abdominal and pelvic region.

[0095] In this embodiment, the dimensions of the aforementioned suspended area molding mold can be preset according to the patient's body shape. For example, the dimensions of the aforementioned suspended area molding mold can be set as follows: width 15-30cm, length 20-40cm, and depth 5-15cm, thereby ensuring that the center of the mold is aligned with the center of the target area in the patient's abdominal and pelvic region.

[0096] After preparing the fixation device for generating the assisted abdominal and pelvic radiotherapy suspended position, step S202 is performed to place the mold for the suspended area and pre-shape the foam substrate.

[0097] In the technical solution provided in step S202 of this application, the patient removes metal objects and lies slowly on the uncured foam substrate in a supine or prone position according to the treatment requirements. The technician assists in adjusting the body position so that the midline of the body coincides with the midline of the device. The bilateral iliac bones, shoulders, thorax, lumbosacral region and upper thighs naturally fall on the foam support area. The suspended area forming mold is placed on the foam substrate corresponding to the lower abdomen position. This avoids direct contact between the abdomen and the foam and allows the temporary shape to be supported only by the suspended area forming mold.

[0098] After placing the mold for the suspended area and pre-shaping the foam substrate, step S203 is performed to expand and cure the foam substrate.

[0099] In the technical solution provided in step S203 of this application, the foam mixing reaction is initiated, and the foam begins to slowly expand and conform to the contours of the human body for shaping. During the foaming process, the patient's position is kept stable, and body movement, rotation, or tilting is avoided until the foam completely covers the chest, back, lumbosacral region, both hips, and upper thighs, forming a convex edge restraint on both sides.

[0100] In this embodiment, after the foam substrate is fully cured and the structure is stable, the mold for the suspended area is removed. If a continuous, smooth and precisely sized downward-concave suspended cavity is formed in the cured and stabilized foam substrate, then the cured and stabilized foam substrate is a fixation device for the suspended position of the abdominal and pelvic radiotherapy.

[0101] After the expanded and cured foam substrate is expanded, step S204 is performed to perform a positioning scan on the patient who has waded into the cured and stabilized expanded foam substrate.

[0102] In the technical solution provided in step S204 of this application, the patient's position is kept unchanged, and the patient who has been placed into the cured and stabilized foam substrate is sent to a computed tomography (CT) scanner for simulated positioning scan.

[0103] In this embodiment, during the scanning process, the patient's lower abdomen is naturally suspended due to the suspended cavity structure, without contact with any supporting structure, and normal tissues such as the small intestine are passively moved out of the irradiation field under the influence of gravity. The resulting CT images are free of artifacts and radiation attenuation interference, clearly showing the positional relationship between the target area and normal tissues.

[0104] After performing a positioning scan on the patient who has been laid into the cured and stabilized foam substrate, step S205 is performed to mark the positioning of the foam device surface and the patient's body surface, and to perform image registration of the individualized contour of the foam device.

[0105] In the technical solution provided in step S205 of this application, after scanning, positioning crosshairs are marked on the surface of the foam device corresponding to the patient's body surface, and positioning parameters are recorded. The CT images are transmitted to the treatment planning system for target delineation, normal tissue delineation, and radiotherapy plan design. The aforementioned individualized foam contour can be used for subsequent CBCT, image registration, and positioning verification.

[0106] After positioning and marking the surface of the foam device and the patient's body surface, and performing image registration on the individualized contour of the foam device, step S206 is executed, and the patient is given assisted radiotherapy using a fixation device for the suspended position of the assisted abdominal and pelvic radiotherapy.

[0107] In the technical solution provided in step S206 of this application, before the auxiliary radiotherapy, the foam suspension fixation device is placed in the same position on the radiotherapy bed. The patient lies accurately in the support area according to the marked line and the outline of the foam, and the abdomen and pelvis naturally fall into the suspension area, keeping the abdomen in a state of no contact and no pressure.

[0108] In this embodiment, the patient's position is verified using a laser positioning line and CBCT. If the positioning error is found to be within the allowable range, radiotherapy is initiated. Each radiotherapy session maintains the same patient position, support, and suspension state to ensure treatment repeatability and dosage accuracy.

[0109] After administering auxiliary radiotherapy to the patient using the fixation device for the suspended position of the auxiliary abdominal and pelvic radiotherapy, step S207 is performed to save and reuse the fixation device for the suspended position of the auxiliary abdominal and pelvic radiotherapy.

[0110] In the technical solution provided in step S207 of this application, the foam suspension fixation device, which has been shaped in a single session, is numbered. The numbered fixation devices are then stored in a dry and ventilated environment, thereby preventing compression, deformation, and contamination. Throughout the patient's entire radiotherapy cycle (e.g., 20-30 sessions), the numbered fixation devices can be reused for positioning the same patient without reshaping, thus ensuring consistent positioning throughout the treatment.

[0111] In this embodiment, the aforementioned fixation device for assisting in the suspended position during abdominoplasty is a single-stage molded foam suspension fixation device. This device eliminates the need for a traditional abdominal suspension bracket, and the integrated, seamless structure formed from foam achieves the suspension function. Therefore, the structure of this device is simpler than that of a traditional abdominal suspension bracket, and its use is also more convenient.

[0112] For example, the aforementioned fixation device for assisted abdominal and pelvic radiotherapy suspension position can be used for radiotherapy of the following conditions: abdominal and pelvic tumors such as rectal cancer, cervical cancer, endometrial cancer, and prostate cancer.

[0113] In this embodiment, the aforementioned suspended mold can be used to generate a fixation device for assisting in the suspended position during abdominal and pelvic radiotherapy. For example, Figure 3 This is a schematic diagram of a suspended mold according to an embodiment of this application, as shown below. Figure 3 As shown, the suspended mold 300 is mapped to the center of the target area in the abdominal and pelvic region onto the position of the expanding foam 301, and the uncured expanding foam 301 is placed there. The uncured expanding foam 301 can be placed on the radiotherapy positioning bed 302.

[0114] In this embodiment, a fixation device for assisting in the suspended position during abdominal and pelvic radiotherapy can be generated by molding and removing the suspended mold. For example, Figure 4 This is a schematic diagram of a fixation device for assisting in the suspended position during abdominoplasty according to an embodiment of this application, as shown below. Figure 4As shown, a suspended mold (such as...) is formed on the cured foam 401 on the radiotherapy positioning bed 400. Figure 3 The suspended region (as shown) is generated.

[0115] Optionally, three-dimensional (3D) printing technology can be used to print a fixation device for assisting in the suspended position during abdominal and pelvic radiotherapy. For example, by acquiring the patient's CT data and performing 3D reconstruction and design on the CT data, a design drawing suitable for the patient can be obtained. This design drawing can be used to describe the shape and color of the fixation device for assisting in the suspended position during abdominal and pelvic radiotherapy. Based on the design drawing, the fixation device for assisting in the suspended position during abdominal and pelvic radiotherapy can be printed using 3D printing technology.

[0116] In this embodiment, during the generation of the auxiliary abdominal and pelvic radiotherapy device, if the radiotherapy subject is on the initial foaming device, a suspended mold that meets the body shape of the radiotherapy subject is deployed in the deployment area. The deployed initial foaming device is then shaped to obtain a shaped foaming device. Then, the suspended mold deployed in the deployment area is removed from the shaped foaming device to obtain the auxiliary abdominal and pelvic radiotherapy device. This achieves the goal of reducing the risk of mis-radiotherapy to areas of the radiotherapy subject that do not require radiotherapy, thereby solving the technical problem of low safety in radiotherapy for radiotherapy subjects and achieving the technical effect of improving the safety of radiotherapy for radiotherapy subjects.

[0117] According to an embodiment of this application, a device for generating an auxiliary abdominal and pelvic radiotherapy device is also provided.
