Definitions
- the invention relates to a radiation therapy system according to the preamble features of claim 1.
- Known radiation therapy systems consist at least of a base on which the patient can be supported, the so-called patient bed, and an irradiation device, in particular a so-called linear accelerator.
- the linear accelerator is usually attached to a framework, the so-called gantry.
- the gantry is usually designed to be movable, i.e. it can be rotated around the patient lying on the couch.
- the radiation field generated in the linear accelerator is bundled in a bundling instrument, the so-called collimator, and shaped if necessary, i.e. the shape of the radiation field is adapted to the contours of the tumor, so that targeted radiation can take place.
- a problem with radiation therapy is to position the tumor and thus the patient relative to the radiation source in such a way that the beam or the radiation field hits the tumor as precisely as possible and adjacent tissue is spared.
- the radiation source can remain stationary and the patient and thus the tumor can be moved relative to it.
- the patient can be fixed and the radiation source can be moved.
- Various systems are known for changing the position of the patient, all of which are based on the fact that the patient firmly fixed on the couch is moved by adjusting the position of the couch.
- DE 197 28 788 describes a method for patient positioning relative to the treatment device.
- the actual position of the patient is determined with the aid of CCD cameras and image processing and morphing and compared with a predetermined target position.
- servo motors of the bed are controlled, which bring the patient back into the desired position. This control is carried out every second or tenth of a second in order to be able to react to the patient's breathing movements.
- a method is also known from DE 198 05 917 with which the position of patients during radiation therapy can be recognized and the patient can be positioned accordingly.
- the surface structure of the patient's body is detected with at least two sensors and compared with a target image, whereby deviations of the current position of the patient from the target position can be recognized.
- a position deviation correction can then be carried out if necessary.
- US Pat. No. 6,052,436 shows a device for radiation therapy in which two guide rails are fixed above the patient, along which a linear accelerator with a collimator attached is moved. With the aid of slots in the guide rails, the plates of the collimator are moved in such a way that the radiation window changes when the linear accelerator moves, in such a way that the shape of the radiation window is adapted to the shape of the tumor.
- the problem remains that the positioning of the patient or, more precisely, the isocenter of the tumor relative to the radiation source is still relatively imprecise.
- the known radiation systems have the disadvantage that the radiation source can only be adjusted to a limited extent relative to the patient, which in particular makes irradiation from unusual angles more difficult or complicated devices are necessary.
- the object of the present invention is therefore to provide a radiation therapy system which avoids the disadvantages described above.
- a system is to be created with which the radiation source can be adjusted as quickly and precisely as possible relative to the patient in order to achieve optimal tumor treatment.
- the radiation therapy system consists at least of a base on which a patient is supported and an irradiation device, in particular a linear accelerator, which generates a treatment beam.
- treatment beam 11 denotes all types of radiation generated by the linear accelerator, that is to say both photons and electron beams.
- the term is intended not only to include punctiform bundles of rays but also so-called radiation fields at least one hexapod is adjustable.
- hexapod denotes a device which works according to the so-called Stewart principle (D. Stewart, "A Platform With Six Degrees of Freedom", UK Institution of Mechanical Engineers Proceedings, 1965- 66, Vol.
- a hexapod has six struts or stamps, particularly hydraulic cylinders or electrospindles, which can be adjusted along their longitudinal axis and each extend between an upper and a lower platform, one of the two platforms being fixed or stationary, while the other by changing the length of the struts, Stamp or spindles is moved.
- the hexapod allows a combined translational and rotational movement along or around the six coordinates (X, Y, Z; theta-X, theta-Y, theta-Z). This means that a hexapod has six degrees of freedom.
- the use of a hexapod to direct the treatment beam therefore enables it to be aligned quickly and precisely.
- Use means that, for example, the gantry is rotated roughly and the fine adjustment can then be carried out in particular by means of the hexapod by aligning the treatment beam with the hexapod.
- This enables particularly quick and precise adjustment.
- the use of the hexapod for aligning the treatment beam enables a relatively small installation space (r hexap ⁇ cn ⁇ ääe) compared to other adjustment options (such as so-called cross tables).
- the hexapod is attached between the linear accelerator and the collimator, in particular that it is attached with an annular disk.
- at least one sensor is provided on the hexapod and / or on the linear accelerator and / or on the collimator with which the position of the patient can be detected.
- two sensors are provided, but it can also be provided that only one sensor is provided on the hexapod or linear accelerator or collimator and the other at any other point in the treatment room. This enables an exact position determination of the patient, since at least two images are generated and can be compared with one another.
- a particularly preferred exemplary embodiment of the invention provides that the hexapod can be controlled in such a way that the treatment beam can track the tumor contour.
- a control can, for example, provide for the tumor contour and the position of the tumor in the patient to be detected by means of methods which generate a three-dimensional image, for example computer tomography (CT).
- CT computer tomography
- the treatment beam is then aligned and moved by means of the hexapod and the beam guiding element set by it so that the treatment beam follows the contours of the tumor.
- this ensures that the tumor is completely irradiated, and on the other hand it prevents that neighboring tissue is also affected by the radiation.
- tracking the treatment beam along the tumor contours enables the lowest possible dose to be used, since uncertainty factors regarding, for example, the tumor size are eliminated and its targeted irradiation is made possible.
- Fig. 1 shows an inventive radiation therapy system in a schematic representation.
- the radiation therapy system according to the invention has one
- the linear accelerator 1 can take any shape, for example it can be designed as a device standing on the floor, or it can be mounted on the ceiling. Furthermore, the linear accelerator 1 will generally be attached to a framework, the so-called gantry. The radiation required for treatment is generated in a known manner in the linear accelerator.
- a hexapod is provided between the head 2 of the linear accelerator 1 and a collimator 11.
- the hexapod has two platforms 3 and 10, the platform 3 being fastened to the linear accelerator 1, preferably to its head 2, and the movable platform 10 being fastened to the collimator 11 for adjusting it.
- any other desired bundling or beam guiding element can also be provided, depending on the desired application.
- the platforms 3 and 10 of the hexapod have an annular design and therefore have passage openings 16 and 17 through which the treatment jet 12 passes. It is preferably provided that the platform 3 is fixed to the linear accelerator 1 or its head 2 is connected, and thus forms the platform of the hexapod, which is fixed in its position.
- the platform 10, is adjustable by changing the length of the struts 4, 5, 6, 7, 8 and 9, the term “struts” also being intended to refer to stamps or spindles with the same effect or generally translational drives.
- the struts 4, 5, 6, 7, 8 and / or 9 are adjustable in length along their longitudinal axis, as indicated by the arrow 18.
- the adjustable platform 10 By changing the length of at least one strut 4, 5, 6, 7, 8, 9, the adjustable platform 10 is thus changed in its position and the collimator 11 is accordingly moved as a beam guiding element. This in turn changes the angle of incidence of the treatment beam 12. Thereby, the treatment beam 12 can be aligned so that it hits the isocenter 14 in the patient 13, which is fixed on a base 15, as precisely as possible.
- Such an isocenter 14 is understood to be, for example, a tumor that is to be treated by means of radiation therapy.
- a sensor system is preferably also provided, with which the position of the patient 13 on the support 15 can be determined.
- sensors 20 and 21 can be provided on the platform, for example.
- Scanning systems can be used as sensors 20 and 21, for example, which continuously scan the body and thus the position of the patient 13 or record the surface contour of the patient 13.
- the sensors 20 and 21 are aligned with the patient 13, as indicated by the dash-dot lines 22 and 23. With the help of the sensors 20 and 21, the position of the patient 13 on the support 15 is thus detected and continuously checked whether the isocenter 14 and the treatment beam 12 are optimally aligned with one another, ie whether the treatment beam 12 hits the isocenter 14 exactly.
- a controller 30 is shown schematically, which is connected via a signal output 31 to the hexapod.
- the controller 30 can also have various inputs, for example the inputs 32 and 33 from the sensors 20 and 21.
- the controller 30 can also have signal inputs from imaging devices, for example a CT. It is provided that the controller 30 permanently and separately controls each individual strut 4, 5, 6, 7, 8, 9 of the hexapod in order to achieve the most exact possible alignment of the treatment beam 12 in all six degrees of freedom.
- An alternative embodiment of the invention provides that the support 15 on which the patient 13 can be placed is designed to be adjustable. This adjustability is achieved in that a hexapod is provided with which the pad 15 can be adjusted.
- the provision of a hexapod for changing the position of the base 15 has the advantage that the hexapod ensures adjustability in six degrees of freedom.
- the pad 15 and with it the patient 13 can be brought into any position in a stepless manner and with only a small space requirement.
- a hexapod enables the base 15 to be adjusted extremely precisely and quickly.
