[0002] With the development of atomic science, radiation therapy using cobalt-60, linear accelerators, electron beams, etc. has become one of the main means of cancer treatment. During radiation therapy, the patient needs to be continuously irradiated with the beam within a certain period of time. During this process, the patient needs to be fixed to a support member and transported to a predetermined position by an adjustment assembly connected to the support member. In conventional treatment devices, the support member has a single shape and size, making it difficult to adapt to patients with different body types and tumor locations. Furthermore, if other equipment is present in the irradiation room and interferes with the movement of a support member of a certain shape and size, irradiation cannot be performed at the optimal irradiation point and angle, resulting in a reduced therapeutic effect.

[0012] Furthermore, a collimator is installed in the irradiation chamber to emit radiation, and the radiation is emitted from the exit of the collimator to define a single beam axis having an optimal treatment point. The laser positioning assembly includes at least two laser irradiation units installed in different orientations, and the lasers emitted from the at least two laser irradiation units have a laser intersection point, and during the treatment process, the optimal irradiation point of the irradiated body, the laser intersection point, and the optimal treatment point overlap.

[0019] Radiation therapy is a common means for treating cancer, and as shown in Figures 1 to 8, a radiation therapy system for performing radiation therapy includes a radiation generation device 1 that generates therapeutic radiation, an irradiation room 2 in which an object to be irradiated with radiation is placed, a control room 3 that controls irradiation, a loading device 4 for transferring and loading the patient, and a positioning device that controls the movement trajectory of the loading device 4.

[0020] As shown in FIG. 3, the support device 4 includes a support member 41 on which a patient is placed, an adjustment assembly 42 that adjusts the spatial position of the support member 41, and a clamp assembly 43 that removably and securely connects the support member 41 to the adjustment assembly 42.

[0021] The support member 41 has various model numbers according to different shapes and / or sizes, for example, a flat-shaped first support member 41' and a chair-shaped second support member 41'', and both the first support member 41' and the second support member 41'' can be set to various sizes and specifications to accommodate patients with different body types and tumor locations. For example, if a patient needs to be irradiated at a certain irradiation angle, but the shape and / or size of the current support member 41 interferes with other devices in the irradiation chamber 2 and prevents it from being adjusted to the specified position, the current support member 41 can be replaced with a support member 41 of a different shape and / or size to achieve the irradiation angle adjustment. Alternatively, if some areas, such as the back of the head, cannot be irradiated when the patient is lying on their back, a high therapeutic effect can be achieved by placing the patient on a support chair.

[0022] 4, the mounting member 41 includes a first surface 411 to which the clamping assembly 43 is attached and a second surface 412 that supports the patient. The adjustment assembly 42 can move the mounting member 41 to provide six degrees of freedom of movement.

[0023] The clamp assembly 43 includes a first positioning block 431 mounted on the first surface 411 of the mounting member 41, a second positioning block 432 mounted on the adjustment assembly 42, and a locking member 433 mounted on the second positioning block 432 and configured to lock or unlock the second positioning block 432 relative to the first positioning block 431. Specifically, the first positioning block 431 is provided with a stopper groove 4311 into which the second positioning block 432 is inserted along a first direction parallel to the first surface 411, a shunt groove 4312 communicating with the stopper groove 4311 in a second direction perpendicular to the first surface 411, and a locking hole 4313 communicating with the stopper groove 4311 and engaging with the locking member 433. The stopper groove 4311 penetrates one surface of the first positioning block 431 in the first direction to form an insertion opening 4314, and the second positioning block 432 is inserted into the stopper groove 4311 from the insertion opening 4314 along the first direction.

[0024] A first direction in which the second positioning block 432 is inserted into the stopper groove 4311 is defined as the front-rear direction, a second direction perpendicular to the first surface 411 as the up-down direction, and a direction perpendicular to both the front-rear direction (first direction) and the up-down direction (second direction) as the left-right direction. The stopper groove 4311 communicates with the shunt groove 4312 in the up-down direction and penetrates the first positioning block 431 in a direction away from the mounting member 41, and the adjustment assembly 42 is connected to the second positioning block 432 through the shunt groove 4312. Because the size of the shunt groove 4312 is smaller than the size of the stopper groove 4311 and the size of the second positioning block 432 in the left-right direction, the second positioning block 432 does not come off the stopper groove 4311 in the up-down direction.

[0025] As shown in Figure 5, the locking member 433 includes an attachment portion 4331 fixedly connected to the second positioning block 432, a locking pin 4332 that can be inserted into or removed from the locking hole 4313, and a first driving member 4333 that drives the locking pin 4332 to be inserted into or removed from the locking hole 4313. The lock hole 4313 penetrates the first positioning block 431 in the left-right direction and communicates with the stopper groove 4311, and the lock pin 4332 selectively prevents movement of the first positioning block 431 relative to the first positioning block 431 in the front-to-back direction by being inserted and removed from the lock hole 4313, and the stopper groove 4311 penetrates only one surface of the first positioning block 431 in the front-to-back and left-to-right directions parallel to the first surface 411, and when the lock pin 4332 is inserted into the lock hole 4313, movement of the second positioning block 432 relative to the first positioning block 431 in the front-to-back and left-to-right directions is prevented, so that the adjustment assembly 42 is removably fixedly connected to the mounting member 41.

[0026] To prevent the first positioning block 431 and the second positioning block 432 from being firmly connected because the lock pin 4332 does not move to a predetermined position, the mounting device 4 further includes a detection assembly (not shown) that determines whether the mounting member 41 is effectively connected to the adjustment assembly 42 by detecting whether the lock pin 4332 moves to a predetermined position.

[0027] As shown in Figures 2 and 7, the positioning device includes a laser positioning assembly 51, an alignment assembly 52, an optical verification assembly (not shown), a distance measurement assembly (not shown), a drive assembly (not shown) that moves the adjustment assembly 42 to move the mounting member 41, and a control assembly (not shown) that controls the movement trajectory of the adjustment assembly 42.

[0028] The adjustment assembly 42 is driven by the drive assembly to move the mounting member 41 and move in six degrees of freedom.

[0029] A collimator 21 is installed in the irradiation chamber 2, and the radiation generated by the radiation generation device 1 is emitted from the exit of the collimator 21, defining a single beam axis X that overlaps with the center line of the collimator 21. On the beam axis X, the optimal treatment point is located 15 to 20 cm away from the exit of the collimator 21, and during the treatment process, the optimal irradiation point on the patient must be aligned with this optimal treatment point.

[0030] 2, the laser positioning assembly 51 includes at least two laser irradiation units installed at different orientations, and the at least two laser irradiation units are installed on two different walls of the irradiation chamber 2, respectively, and typically one of them is installed on the top wall of the irradiation chamber 2. The lasers emitted from the at least two laser irradiation units have a unique laser intersection point that overlaps with the optimal treatment point.

[0031] 7 , the positioning assembly 52 includes a positioning frame 521 whose position relative to the support member 41 is adjustable, support rods 522 connected between the support member 41 and the positioning frame 521 to adjust the relative position of the positioning frame 521 and the support member 41, and a locking member (not shown) for locking the relative position of the positioning frame 521 and the support member 41, and the positioning frame 521 has positioning points. In the embodiment disclosed herein, the support rods 522 have three relatively rotatable rods, and the position of the positioning frame 521 with respect to the support member 41 is adjusted by adjusting the relative angles and positions of two of the three rods. When the patient lies or sits on the support member 41, a medical professional adjusts the support rods 522 to align the positioning points of the positioning frame 521 with the optimal irradiation point for the patient, and then locks the position of the positioning frame 521 with the locking member.

[0032] The optical verification assembly includes a CCD camera and an image processing and identification module.

[0033] The distance measuring assembly measures the distance between the positioning point and the laser intersection point in a direction perpendicular to the second surface 412 of the mounting member 41, and the distance measuring assembly may be a conventional distance meter such as a laser distance meter.

[0034] The CCD camera captures the relevant image, and the image processing and identification module analyzes the coordinates and relative angle of a point on the image captured by the CCD camera.

[0035] The operation process of the positioning device is as follows.

[0036] In S1, the laser positioning assembly 51 marks the optimal treatment point corresponding to the coordinates (X, Y, Z) and relative angle α by the laser intersection point; In step S2, the CCD camera takes a picture of the laser intersection, and the image processing and identification module analyzes the picture and marks the laser intersection in the picture. In step S3, the patient lies or sits on the support member 41, and the medical staff adjusts the support rod 522 to position the positioning point of the positioning frame 521 at the optimal irradiation point of the patient, and then locks the position of the positioning frame 521 with the locking member. In S4, the CCD camera takes a picture of the patient lying or sitting on the support member 41 and the alignment assembly 52 adjusted to a predetermined position, and then the image processing and identification module analyzes and records the coordinates (X1, Y1) and relative angle α1 of the alignment point of the alignment assembly 52 in the picture, and then calculates the coordinate difference values ​​between the alignment point and the laser intersection point as X0=X1-X, Y0=Y1-Y, α0=α1-α; In S5, the control assembly determines the movement trajectory of the adjustment assembly 42 by calculation based on the coordinate difference value acquired from the optical verification assembly, and then controls the drive assembly to move the adjustment assembly 42, thereby moving the optimal irradiation point of the patient on the support member 41 to a position corresponding to the coordinates (x, y) and the relative angle α; In S6, the distance between the positioning point and the laser intersection point in a direction perpendicular to the second surface 412 of the mounting member 41 is measured by the distance measurement assembly; In S7, the control assembly determines the movement trajectory of the adjustment assembly 42 by calculation based on the data obtained from the distance measurement assembly, and then controls the drive assembly to move the adjustment assembly 42, thereby moving the optimal irradiation point of the patient on the support member 41 to the optimal treatment point, i.e., the position corresponding to the coordinates (X, Y, Z) and the relative angle α, and performing treatment.

[0037] Before performing step S3, the placement member 41 may be visually moved to a position close to the laser intersection, and this position is determined by a medical professional based on their experience, taking into account the patient's body type, the optimum irradiation point, and the like.

[0038] Step S6 may be performed before step S5. In this case, steps S5 and S7 are integrated to directly adjust the mounting member 41 to a position corresponding to the coordinates (X, Y, Z) and the relative angle α.

[0039] In the above operation process, a certain point on the adjustment assembly 42 is set as the coordinate origin, and it goes without saying that the coordinate origin may also be set at any other point.

[0040] In the disclosed embodiment of the present invention, the positioning frame 521 is a cross positioning frame, and the positioning point is a cross intersection point; in other embodiments, the positioning frame 521 may be a V-shaped positioning frame, etc., and the positioning point may be any mark point of any positioning frame.

[0041] 8, due to the presence of various devices in the irradiation chamber 2, the adjustment assembly 42 may interfere with these devices at a certain position, resulting in certain limitations on the movement trajectory of the adjustment assembly 42, preventing the optimal irradiation point on the patient from moving to the optimal treatment point. In another embodiment of the present invention, a transmission device 6 is installed between the adjustment assembly 42 and the mounting member 41, thereby ensuring that the mounting member 41 can move relative to the adjustment assembly 42 to maximally move the optimal irradiation point on the patient to the optimal treatment point.

[0042] In the disclosed embodiment of the present invention, the transmission device 6 includes a base 61 installed between the second positioning block 432 and the adjustment assembly 42 and fixedly connected to the adjustment assembly 42, a guide member 62 installed on the base 61, a slider 63 that can slide relative to the guide member 62, a drive block 64 connected between the slider 63 and the second positioning block 432, and a second drive member 65 that moves the drive block 64.

[0043] The guide member 62 is made up of two spaced apart guide rails installed parallel to each other, the slider 63 straddling the guide rails, the drive block 64 fixedly connected to the second positioning block 432 and connected between the second drive member 65 and the slider 63, the second drive member 65 being preferably a motor or alternatively a cylinder, the second drive member 65 moving the drive block 64 to drive the slider 63 to move along the direction defined by the guide member 62, the drive block 64 simultaneously moving the second positioning block 432 to move the mounting member 41 along the predetermined locus of the guide member 62 relative to the adjustment assembly 42. The mounting member 41 and the adjustment assembly 42 are movable relative to each other, and the range of movement of the mounting member 41 can be increased by 30%, thereby increasing the treatable range.

[0044] In the disclosed embodiment of the invention, adjustment assembly 42 is a robotic arm, although in other embodiments adjustment assembly 42 may be mounted to a structure such as a bracket.

[0045] In other embodiments, the driving block 64 may not be installed, and a second positioning block 432 may be adopted instead of the driving block 64; in other examples, the transmission device 6 may be installed between the mounting member 41 and the first positioning block 431, and the transmission device 6 may be installed between the mounting member 41 and the first positioning block 431; in this case, the transmission device 6 and the first positioning block 431 may be installed integrally, and the transmission device 6 and the mounting member 41 may be connected integrally in a quickly detachable manner.

[0046] In the present invention, the clamp assembly 43 is used to quickly attach and detach the support member 41 and the adjustment assembly 42, so that the size and shape of the support member 41 can be freely changed according to actual usage needs, allowing the radiation therapy system to adapt to patients with different body types and tumor locations, increasing the treatment irradiation range, improving efficiency, and reducing the time the operator needs to enter the irradiation chamber 2.

[0047] The mounting member 41 is automatically and quickly moved to a predetermined position by the positioning device, improving treatment efficiency and reducing the time the operator needs to enter the irradiation room 2.

[0048] By installing a transmission device 6 between the mounting member 41 and the adjustment assembly 42, the mounting member 41 and the adjustment assembly 42 can move relative to each other, and the range of movement of the mounting member 41 can be increased by 30%, thereby increasing the range of treatment.

[0049] Neutron capture therapy has been increasingly applied in recent years as an effective means of cancer treatment, with boron neutron capture therapy being the most common, and the neutrons used in boron neutron capture therapy can be supplied from a nuclear reactor or an accelerator. Preferably, the radiation is a neutron beam, the radiation generating device 1 is a neutron beam generating device, and the radiation therapy system is a neutron capture therapy system, and more preferably, the neutron capture therapy system is an accelerator-based boron neutron capture therapy system.
