Abstract

Radiation therapy arrangement comprises a diagnosis device (4, 4~) which moves from a parking position in the region of the radiation outlet tube (12) in the longitudinal direction into a diagnosis position in front of the tube. Preferred Features: The diagnosis device is arranged around the radiation outlet tube in the parking position. The diagnosis device is a computer tomography device and moves on a base rail (30). The diagnosis device moves over the patient bed (24).

Description

  • The The invention relates to a radiotherapy device with a longitudinal extending jet outlet tube of a particle emitter, in particular for ions, Heavy ions or protons and with a diagnostic device, in particular X-ray diagnostic device.
  • at Radiotherapy with the help of ions, especially heavy ions and protons as particles are very powerful and therefore too high volume as well as heavy magnets required to make the particle beam in one desired Orient and focus beam direction. The particle beam is also run in a high vacuum, in order to prevent an interaction with air, causing a widening lead the particle beam would. Due to these significant design measures are in such Radiotherapy device fixed, invariable beam directions intended. The beam is in the end of the particle emitter guided in a jet outlet tube, which is also called "Nozzle" and a beam exit window through which the particle beam exits the high vacuum into the ambient air. Furthermore, the jet outlet pipe usually contains a beam detector and possibly passive beam guiding elements, such as Collimators. The beam detector and the collimators are common in a measuring chamber upstream of the exit window arranged.
  • For a successful one Radiotherapy must be the target volume of the patient to be treated be aligned exactly to the particle beam to damage from healthy tissue if possible to avoid. Before radiotherapy is usually a so-called Radiation plan created on the basis of a previous diagnosis, on the Basis the parameters of radiotherapy are adjusted. In particular, this is an X-ray performed with a computer tomograph. In 3-dimensional x-ray image the exact location of the pathological target volume is defined and understood by appropriate measures, for example Markings on the body of the patient, arrested. Since between the first planning picture creation and targeting and performing radiotherapy a considerable amount of time passes, becomes regular immediately before the implementation Radiotherapy another X-ray image for position verification of the target volume. This x-ray picture takes place directly at the irradiation site for the particle irradiation. For one preferably exact position verification is the use of a computer tomograph advantageous.
  • From the DE 38 28 639 A1 Such a radiation therapy system can be seen in which the particle beam is oriented in the vertical direction and a computer tomograph is provided, which is movable transversely to the particle beam in the horizontal direction.
  • Here However, there is the problem that the large-volume computed tomography takes up a lot of space in the treatment room and that the treatment room usually very expensive, since elaborate radiation protection measures required are.
  • Of the Invention is based on the object, a cost-effective radiotherapy device indicate at the same time a good position verification immediately in the treatment room is.
  • The The object is achieved by a radiotherapy device according to claim 1. Thereafter, it is provided that a diagnostic device, in particular X-ray diagnostic apparatus, from a withdrawn Parking position in the region of the jet outlet tube in the longitudinal direction, So along the Strahlaus outlet tube, forward in a diagnostic position is arranged movable in front of the jet outlet tube.
  • By This measure is therefore not additional Space required in the irradiation room because the diagnostic device in the longitudinal direction and thus can be moved in the beam direction and thus no additional Space needed. Also, no extra Space in transverse direction required, as the diagnostic device in the Parking position is arranged parallel to the jet outlet pipe.
  • According to one Expedient development here is the diagnostic device in the Parking position arranged around the jet outlet tube around. The diagnostic device is therefore at least partially annular. Conveniently, in this case, the diagnostic device is an X-ray computed tomography with a torus-shaped or ring-shaped Examination unit arranged around the jet outlet tube. The opening The examination unit forms the diagnostic space into which the patient is admitted or with which the CT device is moved over the patient becomes. With this diagnostic room is now in the park position of the Computer tomograph over the jet outlet tube drove, so that a very space-saving Arrangement results.
  • To a safe and mechanically sufficiently stable method of the diagnostic device to he possible, this is movable on at least one bottom rail. The mechanical forces are therefore taken from the bottom rail. In order not to mechanically load the jet outlet tube through the diagnostic device, the jet outlet tube is preferably mechanically decoupled from the diagnostic device, ie no mechanical forces are transmitted to the jet outlet tube by the diagnostic device.
  • According to one expedient development is the jet outlet pipe over a first, rear travel of Diagno segeräts cantilevered. The jet outlet tube thus protrudes in a horizontal direction cantilevered into the room without being supported on the floor or suspended from the ceiling. This is a method of the annular diagnostic device on the Beam outlet tube easily possible. The rear travel path here has a length at least approaching the length of the diagnostic device longitudinal corresponds to this as possible Completely to move into a parking position, so that it is no longer on the jet outlet pipe longitudinal protrudes. To here sufficient mechanical stability of the self-supporting Beam exit tube can obtain this suitable struts or reinforcements exhibit.
  • Preferably In front of the jet outlet tube is a patient positioning device with a longitudinal direction extending patient bed arranged. By aligning in longitudinal direction is the diagnostic device by a simple process in the longitudinal direction in the front Diagnosis position movable and the diagnosis can be performed.
  • Conveniently, Here is the diagnostic device on the Patient couch away movable, i. the patient bed is from recorded in the inner annulus of the computer tomograph. To this to enable is similar as the jet outlet tube and the patient bed on a second front travel of the diagnostic device cantilevered. For this purpose, the patient bed is suitably attached to the patient positioning device attached.
  • There the radiation during radiotherapy under a specified Orientation regarding the patient must, it is usually required that the patient on the patient bed from the diagnosis position into one Irradiation position is brought. To do this without a rearrangement to enable the patient is the patient bed in a preferred embodiment to a Rotatable axis rotatable and also translationally movable. The patient bed preferably has at least four axes of rotation (isocentric, eccentric, pitch and roll) and three degrees of freedom for linear movements (in the longitudinal direction (In / out); perpendicular to the longitudinal direction (right / left) as well as lifting movement (up / down)). Through these degrees of freedom of movement there is therefore the possibility the target volume to be irradiated exactly to the so-called isocenter to align the particle beam.
  • One embodiment The invention will be explained in more detail below with reference to FIGS. Show it each in schematic and highly simplified representations:
  • 1 a room with a radiation therapy device arranged therein in a side view,
  • 2 the radiotherapy device according to 1 in a supervision as well

Through a side wall 8th the therapy room 2 occurs in the longitudinal direction 10 along the horizontal extending beam outlet tube 12 in the therapy room 2 one. The jet outlet pipe 12 is connected to a particle emitter, not shown here, which is designed to generate ions, in particular heavy ions or protons. These are irradiated in a high vacuum through the jet outlet tube 12 guided and leave this frontally on an exit window. Longitudinal 10 Following the exit window is a measuring chamber 14 arranged, with the help of which the beam position and the dose of the particle beam is checked during the irradiation.
  • Due to the high-energy particle radiation, at least some walls of the therapy room have 2 special radiation protection measures 16 to prevent the interference of adjacent rooms with the particle radiation. The irradiation room is in particular due to these radiation protection measures 16 very expensive and expensive, the costs increase with increasing volume of space. Overall, the therapy room 2 therefore kept as compact as possible.
  • Next to the jet outlet pipe 12 and the computer tomograph 4 is in the therapy room 2 nor a patient positioning device 22 arranged. This includes a patient bed 24 , which are on a support column 26 is arranged.

  • In the same way is the computer tomograph 4 ' in his diagnostic position also on the patient bed 24 Therefore, this also surrounds for diagnostic purposes also ring-shaped, as is provided in a conventional computed tomography examination. In his diagnostic position is the computer tomograph 4 ' in this case arranged such that the target volume to be examined in the middle of the diagnostic space in the isocenter 34 located.
  • The travel path of the computer tomograph 4 . 4 ' includes a rear travel 36A and a front travel path 36B , The rear travel path 36A corresponds to the travel path in which the computer tomograph 4 still at least partially around the jet outlet tube 12 is oriented. At the end of the measuring chamber 14 having jet outlet tube 12 This is followed by a mean traversing path not shown here, the length of which is the distance between the measuring chamber and the patient bed 24 equivalent. The front travel path 36B is finally the travel path in which the computed tomograph 4 ' at least partially above the patient bed 24 is arranged.
  • To the procedure over the jet outlet pipe 12 on the one hand and on the patient bed 24 on the other hand, are the jet outlet tube 12 and the patient bed 24 over the two travel paths 36A . 36B cantilevered. A mechanical coupling with the computer tomograph 4 . 4 ' does not exist. Rather, this is about these two components in the longitudinal direction 10 freely movable.
  • In the embodiment is above the computer tomograph 4 . 4 ' in the area of the ceiling 20 a power supply device 38 for the computer tomograph 4 . 4 ' intended. This includes a power supply package 40 or cable, which is guided over the entire travel path away in the manner of a drag chain in ceiling-side guides and with the computer tomograph 4 . 4 ' connected is. Both the floor rails 30 as well as the ceiling-side guide for the power supply package 40 extend over the entire travel path 36 , which can be up to 4 m, for example, and the approximately from the rear side wall 8th up to the support column 26 extends.
