[0019] An application method of a dual-treatment-room boron neutron therapy center comprises the following steps:

[0020] A1. Single treatment room usage scenario:

[0021] a. Patient preparation and simulation positioning

[0022] The patient enters the first pre-preparation room / second pre-preparation room through the first pre-maze / second pre-maze. The first treatment couch moves along the first track to the first pre-preparation room / the second treatment couch moves along the second track to the second pre-preparation room. The patient lies on the first treatment couch / second treatment couch and is precisely positioned using the first simulation positioning laser light and the first simulation positioning DR / the second simulation positioning laser light and the second simulation positioning DR. At this time, the first outer protection door and the first inner protection door / the second outer protection door and the second inner protection door are all closed, and the radiation dose is reduced by the barriers of the doors. The medical staff completes the patient's simulation positioning in the low-dose area.

[0023] b. Transfer the patient to the treatment room

[0024] After the simulated positioning is completed, the first outer protective door / second outer protective door opens. After the medical staff evacuates, the first outer protective door / second outer protective door closes, and the first inner protective door / second inner protective door opens. The patient is automatically transported to Treatment Room 1 on the first treatment bed along the first running track, or the second treatment bed is automatically transported to Treatment Room 2 along the second running track.

[0025] c. Radiation protection start before treatment

[0026] The first blocker / second blocker automatically rises to block the gamma rays generated by activation from the first beam outlet / second beam outlet, ensuring the safety of Treatment Room 1 / Treatment Room 2 in the non-irradiation state; the first outer protection door and the first inner protection door / the second outer protection door and the second inner protection door close in conjunction to form a double protection barrier;

[0027] d. Neutron beam irradiation therapy

[0028] When the patient reaches the designated position, the first blocker / second blocker descends, and the first beam exits the beam port / second beam exits the beam port for irradiation treatment; when the treatment is completed, the first beam exits the beam port / second beam exit stops irradiation, and the first blocker / second blocker rises;

[0029] e. Evacuation after treatment and equipment reset

[0030] The first inner protective door / second inner protective door is opened, and the patient is automatically transported to the first pre-preparation room / the second treatment bed along the first running track to the second pre-preparation room. The first inner protective door / second inner protective door is closed. The first outer protective door / second outer protective door is opened, and medical staff enter the first pre-preparation room / second pre-preparation room. The first outer protective door / second outer protective door is closed. Medical staff assist the patient in untying and changing beds, checking the equipment status, and preparing for the next round of treatment. The first outer protective door / second outer protective door is opened, and medical staff assist the patient in leaving the first pre-preparation room / second pre-preparation room. The first outer protective door / second outer protective door is closed.

[0031] A2. Dual treatment room usage scenarios:

[0032] a. Time-sharing scheduling and resource allocation

[0033] Through the intelligent time-sharing control module, when neutron irradiation is being carried out in treatment room 1, patients in treatment room 2 are positioned in the second pre-preparation room; conversely, when neutron irradiation is being carried out in treatment room 2, patients in treatment room 1 are positioned in the first pre-preparation room, achieving alternating use and reducing waiting time. The BNCT accelerator switches the beam direction by time-sharing, supplying beams to only one treatment room at a time.

[0034] b. Radiation protection linkage

[0035] The accelerator circulating cooling water trench and the accelerator power and weak cable trench in the accelerator hall are laid out independently to reduce electromagnetic interference and ensure the stability of the simultaneous operation of the two treatment rooms;

[0036] A3. Emergency handling:

[0037] a. Emergency procedures for treatment interruption

[0038] If the patient needs to be evacuated urgently, the medical staff triggers the emergency stop button through the control system in the non-radiation supervision area with one click, immediately closes the first beam outlet / the second beam outlet, and at the same time raises the first blocker / the second blocker to block radiation. The first inner protective door / the second inner protective door opens, and the patient is automatically transported to the first pre-preparation room / the second treatment bed along the first running track to the second pre-preparation room. The first inner protective door / the second inner protective door closes; the first outer protective door / the second outer protective door opens, and the medical staff enters the first pre-preparation room / the second pre-preparation room. The first outer protective door / the second outer protective door closes, and the medical staff assists the patient in untying and changing beds. The first outer protective door / the second outer protective door opens, and the medical staff assists the patient in leaving the first pre-preparation room / the second pre-preparation room. The first outer protective door / the second outer protective door closes;

[0039] b. Countermeasures for equipment failure

[0040] The first outer protective door, the first inner protective door, the second outer protective door and the second inner protective door shall remain closed in the event of a power outage or failure to prevent radiation leakage;

[0041] The accelerator's circulating cooling water trench is monitored in real time through a pressure-sensing water leakage detection device. If a leak is found, the control system will automatically alarm.

[0042] Preferably, in step A1 a, the patient is pre-positioned: according to the treatment plan irradiation position combined with the image, the six-axis robotic arm is guided to perform patient pre-positioning in the first pre-preparation room / the second pre-preparation room; based on the first simulation positioning laser light and the first simulation positioning DR in the first pre-preparation room / the second simulation positioning laser light and the second simulation positioning DR in the second pre-preparation room, the first treatment bed / the second treatment bed is moved to assess the position of the patient closest to the beam outlet;

[0043] Boron concentration sampling: within 30 minutes to 2 hours before the patient receives treatment, some blood boron samples may be collected and sent for testing;

[0044] In step A1 (b), the RFID positioning chip and the LiDAR obstacle avoidance module are integrated into the first and second operating tracks to control the transport time to ≤ 90 seconds, ensuring a safe and efficient transport process.

[0045] In step A1 (d), during the radiation therapy process, treatment room 1 and the first pre-preparation room, or treatment room 2 and the second pre-preparation room are physically isolated and time-sharing controlled to ensure normal access to the low-dose area during non-treatment periods.

[0046] Auxiliary functions of the treatment process: 1) Vital sign monitoring during irradiation: The respiratory monitoring equipment and heart rate monitoring equipment are led out from the strong and weak cable trench of the equipment in Room 1 / the strong and weak cable trench of the equipment in Room 2 to the first pre-preparation room / the second pre-preparation room for placement to detect vital signs; 2) Placement of rescue equipment: During irradiation treatment, the rescue equipment is placed in the first pre-preparation room / the second pre-preparation room; 3) Placement of boron drug injection equipment: During irradiation treatment, the main boron drug equipment is placed in the first pre-preparation room / the second pre-preparation room, and the infusion tube is introduced into the patient treatment position through the strong and weak cable trench of the equipment in Room 1 / the strong and weak cable trench of the equipment in Room 2.

[0047] The application method of the dual-treatment room boron neutron therapy center also includes the daily maintenance and inspection of the dual-treatment room boron neutron therapy center:

[0048] a. Equipment inspection and maintenance

[0049] Lead the strong and weak cable trenches of equipment in room 1 and room 2 to a non-radiated area to facilitate rapid fault location and repair, reducing downtime;

[0050] Regularly check the response time of the first and second blockers, and whether the electromagnetic lock can perform locking and unlocking operations as expected under normal working conditions to ensure that the fail-safe mechanism is effective;

[0051] Regularly clean the power and weak cable trenches for equipment in Room 1, the power and weak cable trenches for equipment in Room 2, the accelerator power and weak cable trenches, and the accelerator circulating cooling water trenches, and check the function of the pressure-sensitive water leakage detection device;

[0052] b. Radiation protection system verification

[0053] Use a portable radiation dosimeter to regularly test the radiation dose in the first pre-maze, second pre-maze, accelerator pre-maze, treatment room 1 and treatment room 2. Use a portable radiation dosimeter to regularly test the radiation dose in the areas surrounding the first outer protection door, first inner protection door, second outer protection door, second inner protection door and accelerator protection door to ensure compliance with IAEA TRS398 safety standards.

[0054] Compared with the existing technology, the dual-treatment-room boron neutron therapy center and its application method have the following beneficial effects:

[0055] 1. Ultra-high space utilization efficiency and cost control:

[0056] Ultra-compact layout: Through the regularly arranged dual-treatment room dual-purpose radiation protection maze and intelligent time-sharing control system, the floor space of traditional treatment buildings is significantly reduced, significantly reducing construction costs and land resource consumption, and improving the building's economic efficiency.

[0057] Modular design: With regular structure and clear layout, it breaks the difficulty and confusion of traditional irregular layout, facilitates construction, personnel diversion and comprehensive hospital construction, and has good replicability and promotion value, supporting the subsequent expansion and functional upgrade of the hospital, and adapting to the needs of medical institutions of different sizes.

[0058] 2. All-round radiation protection:

[0059] Trinity active protection: "Maze, gating, and blocker" collaborative protection architecture, dual pre-preparation rooms effectively separate the areas, and simulated positioning is performed in the pre-preparation room. After entering the treatment area, medical staff do not need to reposition themselves, thereby reducing the risk of radiation exposure to medical staff, engineers, and non-patients during treatment. Composite maze structure: Reduce the risk of radiation leakage through multiple corners and shielding layer design. Dynamic gating technology: The front protection door is linked to the treatment room and the pre-treatment room, and automatically closes during treatment to minimize the risk of lateral exposure to medical staff; dose optimization strategy: Before treatment, simulated positioning DR and lidar scanning are used for rapid positioning, shortening the patient positioning time and indirectly reducing the cumulative radiation dose, which not only improves treatment efficiency but also reduces patient waiting time.

[0060] 3. Equipment compatibility and convenient operation and maintenance:

[0061] Equipment compatibility: The separate layout of the power and weak-voltage cable trenches and the cooling water circulation system reduces electromagnetic interference and improves equipment reliability. Maintenance convenience: A pressure-sensitive leak detection device is built into the trench to monitor pipeline safety in real time. All cable trays are centrally routed to a non-radiation area, streamlining daily maintenance. The rational layout and integration of the power and weak-voltage cable trenches and the cooling water piping system optimizes equipment wiring and cooling water system layout. This design is not only aesthetically pleasing and practical, but also complies with relevant safety standards, facilitating subsequent installation and maintenance, reducing downtime, and improving equipment operational and maintenance efficiency.

[0062] 4. Intelligent radiation monitoring and adaptive protection:

[0063] Multi-dimensional radiation reduction technology: The dual-door, dual-chamber protective structure is optimized through a gradient shielding design, specifically optimizing the door thickness, to ensure effective protection while reducing material costs. Time-based and zoned radiation management: Treatment rooms are physically separated from preparation rooms, allowing normal access to low-dose areas during non-treatment periods. Environmental friendliness: Through optimized radiation shielding, radiation levels in the surrounding area meet international safety standards (such as IAEA TRS398).

[0064] 5. Adaptability:

[0065] The standardized and modular design facilitates replication and promotion and is suitable for medical institutions of different sizes.

[0066] Overall, the present invention improves space utilization, reduces construction and operation costs, and enhances treatment safety, efficiency, and patient experience through optimized design and integrated planning, with significant economical, practical, and safe benefits.

[0073] The second treatment space is provided with a second pre-maze 6, a second pre-preparation room 7, and a second treatment room 8 in the order of entry. The second pre-preparation room 7 and the second treatment room 8 are connected by a second running track 17, and a second treatment bed 18 is movably arranged on the second running track 17.

[0074] An accelerator hall 1 is set between the treatment room 1 5 and the treatment room 2 8, and a BNCT accelerator 9 is placed in the accelerator hall 1. The first beam outflow port 15 of the BNCT accelerator 9 extends into the treatment room 1 5, and a first blocker 16 is provided at the first beam outflow port 15 in the treatment room 1 5. The second beam outflow port 21 of the BNCT accelerator 9 extends into the treatment room 2 8, and a second blocker 22 is provided at the second beam outflow port 21 in the treatment room 2 8.

[0075] The blocker lowers, and the beam exits the beam port for irradiation treatment. After treatment is complete, the blocker promptly raises to block the gamma rays generated by activation from the beam exit. The blocker is rapidly raised and lowered via a hydraulic / electric drive system, with an average response time of 4.2 seconds in laboratory testing. Dual redundant electromagnetic locks provide a fail-safe mechanism, effectively blocking the radiation dose at the beam exit port, creating a safe environment that meets requirements and provides effective protection.

[0076] Preferably, the accelerator hall 1 is a rectangular room, with one wall adjacent to treatment room 1 5 and the other wall adjacent to treatment room 2 8. Treatment room 1 5 and treatment room 2 8 are arranged perpendicular to each other, and the first running track 11 and the second running track 17 are arranged perpendicular to each other. Both the first running track 11 and the second running track 17 are integrated with RFID positioning chips and laser radar obstacle avoidance modules, which can shorten the transportation time to ≤ 90 seconds.

[0087] A trench 30 for strong and weak cables for the second-room equipment is dug along the bottom edge of the wall in the second pre-maze 6, the second pre-preparation room 7, and the second treatment room 8. The trench 30 for strong and weak cables for the second-room equipment is led out from the wall of the second pre-maze 6.

The patient lies on the first treatment couch 12 / second treatment couch 18 and is precisely positioned using the first simulation positioning laser light 13 and the first simulation positioning DR 14 / the second simulation positioning laser light 19 and the second simulation positioning DR 20. At this time, the first outer protection door 23 and the first inner protection door 24 / the second outer protection door 25 and the second inner protection door 26 are all closed. The radiation dose is reduced by the barriers of the doors, and the medical staff completes the patient's simulation positioning in the low-dose area.

[0093] Preferably, in step a of step A1, the patient is pre-positioned: according to the treatment plan irradiation position combined with the image, the six-axis robotic arm is guided to perform patient pre-positioning in the first pre-preparation room 4 / the second pre-preparation room 7; with the first simulation positioning laser light 13 and the first simulation positioning DR14 of the first pre-preparation room 4 / the second simulation positioning laser light 19 and the second simulation positioning DR20 of the second pre-preparation room 7 as a reference, the first treatment bed 12 / the second treatment bed 18 is moved to assess the position of the patient closest to the beam outlet;

After the medical staff evacuates, the first outer protective door 23 / second outer protective door 25 is closed, and the first inner protective door 24 / second inner protective door 26 is opened. The patient is automatically transported to treatment room 1 5 on the first treatment bed 12 along the first operating track 11, and the second treatment bed 18 is automatically transported to treatment room 2 8 along the second operating track 17.

[0097] Preferably, in step A1 b, the transportation time is controlled to be ≤90 seconds by integrating the RFID positioning chip and the laser radar obstacle avoidance module in the first running track 11 / the second running track 17, ensuring the safety and efficiency of the transportation process; the patient is transported from the track to the beam outlet and combined with programmed movement to restore the patient's position and transport him to the irradiation treatment position.

[0098] c. Radiation protection start before treatment

[0099] The first blocker 16 / the second blocker 22 automatically rises to block the gamma rays generated by activation and passing through the first beam outlet 15 / the second beam outlet 21, ensuring the safety of the treatment room 1 5 / the treatment room 2 8 in the non-irradiation state; the first outer protection door 23 and the first inner protection door 24 / the second outer protection door 25 and the second inner protection door 26 are closed in conjunction to form a double protection barrier; at this time, there is no need for medical staff to reposition themselves, and the medical staff are isolated outside the treatment area.

[0100] d. Neutron beam irradiation therapy

[0101] When the patient arrives at the designated location, the medical staff in the non-radiation monitoring area controls the first blocker 16 / the second blocker 22 to descend through the control system, and the first beam outlet 15 / the second beam outlet 21 is used for irradiation treatment. When the treatment is completed, the medical staff in the non-radiation monitoring area controls the first beam outlet 15 / the second beam outlet 21 to stop irradiation through the control system, and the first blocker 16 / the second blocker 22 is raised.

[0102] Preferably, in step A1 d, during the irradiation treatment process, the first treatment room 5 and the first pre-preparation room 4 / the second treatment room 8 and the second pre-preparation room 7 are physically isolated and time-sharing controlled to ensure that the low-dose area can be normally accessed during non-treatment periods;

[0103] Auxiliary functions of the treatment process: 1) Vital sign monitoring during irradiation: The respiratory monitoring equipment and heart rate monitoring equipment are led out from the strong and weak cable trench 29 of the equipment in room 1 / the strong and weak cable trench 30 of the equipment in room 2 to the first pre-preparation room 4 / the second pre-preparation room 7 for placement to detect vital signs; 2) Placement of rescue equipment: During irradiation treatment, the rescue equipment is placed in the first pre-preparation room 4 / the second pre-preparation room 7; 3) Placement of boron drug injection equipment: During irradiation treatment, the main boron drug equipment is placed in the first pre-preparation room 4 / the second pre-preparation room 7, and the infusion tube is introduced into the patient treatment position through the strong and weak cable trench 29 of the equipment in room 1 / the strong and weak cable trench 30 of the equipment in room 2.

[0104] e. Evacuation after treatment and equipment reset

[0105] The first inner protective door 24 / second inner protective door 26 is opened, and the patient is automatically transported along the first running track 11 to the first pre-preparation room 4 / the second treatment bed 18 is automatically transported along the second running track 17 to the second pre-preparation room 7. The first inner protective door 24 / second inner protective door 26 is closed; the first outer protective door 23 / second outer protective door 25 is opened, and medical staff enter the first pre-preparation room 4 / second pre-preparation room 7. The first outer protective door 23 / second outer protective door 25 is closed, and medical staff assists the patient in untying and changing beds, checks the equipment status, and prepares for the next round of treatment; the first outer protective door 23 / second outer protective door 25 is opened, and medical staff assists the patient in leaving the first pre-preparation room 4 / second pre-preparation room 7. The first outer protective door 23 / second outer protective door 25 is closed;

[0106] A2. Dual treatment room usage scenarios:

[0107] a. Time-sharing scheduling and resource allocation

[0108] Through the intelligent time-sharing control module, when neutron irradiation is being carried out in treatment room 1 5, patients in treatment room 2 8 are positioned in the second pre-preparation room 7; conversely, when neutron irradiation is being carried out in treatment room 2 8, patients in treatment room 1 5 are positioned in the first pre-preparation room 4. This allows for alternating use and reduces waiting time. The BNCT accelerator 9 switches the beam direction by time-sharing, supplying beams to only one treatment room at a time.

[0109] Coordinate the beam release time of treatment room 1 5 and treatment room 2 8 to avoid neutron source overload; the first pre-preparation room 4 and the second pre-preparation room 7 operate independently, and patients can alternately enter treatment room 1 5 and treatment room 2 8 to achieve seamless connection;

[0110] b. Radiation protection linkage

[0111] The accelerator circulating cooling water trench 28 and the accelerator power and weak cable trench 27 in the accelerator hall 1 are laid out independently to reduce electromagnetic interference and ensure the stability of the simultaneous operation of the two treatment rooms;

[0112] The synergistic effect of the front maze and protective door is set up to ensure that the radiation leakage risk of the double treatment rooms can be independently controlled.

[0113] A3. Emergency handling:

[0114] a. Emergency procedures for treatment interruption

[0115] If the patient needs to be evacuated urgently, the medical staff will trigger the emergency stop button in the non-radiation monitoring area through the control system, immediately close the first beam outlet 15 / the second beam outlet 21, and at the same time raise the first blocker 16 / the second blocker 22 to block the gamma rays. The first inner protection door 24 / the second inner protection door 26 will be opened, and the patient will be automatically transported to the first pre-preparation room 4 along the first running track 11 via the first treatment bed 12 / the second treatment bed 18 will be automatically transported to the second pre-preparation room along the second running track 17. Room 7, the first inner protection door 24 / the second inner protection door 26 are closed; the first outer protection door 23 / the second outer protection door 25 are opened, and the medical staff enters the first pre-preparation room 4 / the second pre-preparation room 7. The first outer protection door 23 / the second outer protection door 25 are closed, and the medical staff assists the patient in untying and changing beds. The first outer protection door 23 / the second outer protection door 25 are opened, and the medical staff assists the patient in leaving the first pre-preparation room 4 / the second pre-preparation room 7. The first outer protection door 23 / the second outer protection door 25 are closed;

[0116] After the emergency stop is triggered, the radiation dose in the treatment room is monitored in real time, and automatic transfer is initiated after the safety threshold is confirmed.

[0117] b. Countermeasures for equipment failure

[0118] The first outer protection door 23, the first inner protection door 24, the second outer protection door 25 and the second inner protection door 26 remain closed in the event of a power outage or failure to prevent radiation leakage;

[0119] The accelerator circulating cooling water trench 28 is monitored in real time by a pressure-sensitive water leakage detection device. If a leak is found, the control system automatically alarms.

[0120] A4. Special scenario applications:

[0121] a. Pediatric or mobility-impaired patients

[0122] The track system supports customized fixation devices to ensure smooth and safe patient transfer.

[0123] An emergency call button is added in the first pre-preparation room 4 / the second pre-preparation room 7. The emergency call button is connected to the alarm function of the control system through a circuit, so that medical staff can quickly respond to sudden needs.

[0124] b. High-dose treatment requirements

[0125] Through fractionated irradiation and dynamic gating technology, the beam release timing is optimized and the cumulative dose of single radiation is reduced.

[0126] The application method of the dual-treatment room boron neutron therapy center also includes the daily maintenance and inspection of the dual-treatment room boron neutron therapy center:

[0127] a. Equipment inspection and maintenance

[0128] Lead the strong and weak cable trench 29 for equipment in room 1 and the strong and weak cable trench 30 for equipment in room 2 to a non-radiated area to facilitate rapid fault location and maintenance, reducing downtime;

[0129] Regularly check the response time of the first blocker 16 and the second blocker 22, and whether the electromagnetic lock can perform the locking and unlocking operations as expected under normal working conditions to ensure that the fail-safe mechanism is effective;

[0130] Regularly clean the power and weak cable trench 29 for equipment in Room 1, the power and weak cable trench 30 for equipment in Room 2, the accelerator power and weak cable trench 27, and the accelerator circulating cooling water trench 28, and check the function of the pressure-sensitive water leakage detection device;

[0131] b. Radiation protection system verification

[0132] Use a portable radiation dosimeter to regularly detect the radiation dose in the first pre-maze 3, the second pre-maze 6, the accelerator pre-maze 2, the treatment room 1 5 and the treatment room 2 8. Use a portable radiation dosimeter to regularly detect the radiation dose in the areas surrounding the first outer protection door 23, the first inner protection door 24, the second outer protection door 25, the second inner protection door 26 and the accelerator protection door 10 to ensure compliance with the IAEA TRS398 safety standard.

[0133] Simulate extreme scenarios, such as the beam release state when the door is not closed, to verify the reliability of the intelligent protection system.

[0134] After practical application, the specific advantages of this treatment center are as follows:

[0135] 1. Save space and reduce costs: Through optimized design, the building area of the double-level treatment rooms and double pre-preparation rooms has been compressed to more than 400 square meters, saving more than 50% of the existing equipment floor space of 800 square meters, 900 square meters, or even thousands of square meters, thereby significantly reducing construction costs and land use requirements.

[0136] 2. Protecting personnel safety: The dual-preparation room design significantly reduces the radiation exposure risk for medical staff, engineers, and non-patient personnel during BNCT treatment, thereby maximizing the protection of medical staff's lives and health.

[0137] 3. Improved protection effectiveness and reduced construction costs: Each treatment room is equipped with a dedicated pre-preparation room, effectively separating high-dose and low-dose areas. This minimizes the risk of radiation leakage through time-sharing management, thereby reducing the construction costs of radiation protection equipment. The BNCT accelerator switches the beam direction by time, delivering the beam to only one treatment room at a time.

[0138] 4. Simplified layout and easy construction: Breaking the traditional irregular layout pattern, adopting a design scheme with regular structure and clear layout, avoiding the construction difficulty and spatial chaos caused by traditional design, while also facilitating the efficient diversion of personnel and the comprehensive construction of the hospital.

[0139] 5. Integrated planning for easy installation and maintenance: By utilizing the strong and weak current trenches and circulating cooling water trenches in the accelerator hall 1, the cable trays and circulating cooling water pipes used on the accelerator are integrated and arranged, and reasonably led out. This is not only beautiful and practical, but also meets relevant regulations, enables targeted maintenance, reduces downtime, and improves maintenance efficiency. In addition, the strong and weak current trenches in Treatment Room 1 5 and Treatment Room 2 8 are scientifically laid out, and the cable trays of all indoor electrical equipment are integrated and led out to the non-radiation supervision area, further optimizing the spatial layout, reducing equipment operation interference, and improving equipment utilization efficiency. This integrated design not only improves construction and utilization efficiency, but also facilitates the subsequent expansion and renovation of the hospital. It can be said that it is both practical and beautiful, setting an example for standardized construction.

[0140] The implementation of the present invention not only reflects the efficient use of medical space, but also pays attention to radiation protection and personnel safety, and provides a more economical, safe and efficient solution for boron neutron therapy.
