Abstract
Abstract The body support can be used as a part of the reclining surface in a patient's couch intended for use in radiation therapy. It consists of a H-shaped frame with two parallel lateral beams linked together by a central transverse beam. The supporting surfaces divided by the central transverse beam are provided with transparent string tensioning which is secured exclusively to the two lateral beams. The external edges of the body support parallel to the central beam are free of radiation-attenuating frame elements so that uninterrupted dynamic radiation treatment is possible when the direction of radiation is changed from one side of the supporting surface to the other one.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A radiation-permeable body support having a body support surface as a part of the reclining surface in a patient's couch used in radiation therapy in which a radiation emitting apparatus moves in a first plane, comprising: an H-shaped frame having two parallel lateral beams and a central beam interconnected between said two parallel lateral beams, said central beam extending transverse to the first plane and dividing the body support surface into two supporting surfaces lying in a second plane transverse to the first plane, said two parallel beams being in the same plane as said central beam and not connected by any frame parts other than said central beam; and a transparent stringing being anchored solely to said two parallel lateral beams connected to one another by said central beam and forming at least one of said two supporting surfaces.
Claim 2
Dependent Claim
140 words
A radiation-permeable body support having a body support surface as a part of the reclining surface in a patient's couch used in radiation therapy in which a radiation emitting apparatus moves in a first plane, comprising: an H-shaped frame having two parallel lateral beams and a central beam interconnected between said two parallel lateral beams, said central beam extending transverse to the first plane and dividing the body support surface into two supporting surfaces lying in a second plane transverse to the first plane, said two parallel beams being in the same plane as said central beam and not connected by any frame parts other than said central beam; and a transparent stringing being anchored solely to said two parallel lateral beams connected to one another by said central beam and forming at least one of said two supporting surfaces.
Claim 3
Dependent Claim
15 words
A body support according to claim 1, in which said lateral beams are outwardly biased.
Claim 4
Dependent Claim
40 words
A body support according to claim 1, in which at least one string is provided for the stringing forming said one supporting surface, said stringing being arranged in a meander-like disposition in parallel portions at uniform distances from one another.
Claim 5
Dependent Claim
20 words
A body support according to claim 3, in which said stringing is reinforced at the ends of said lateral beams.
Claim 6
Dependent Claim
31 words
A body support according to calim 3, in which said stringing is covered with a transparent covering foil which is likewise braced between said two parallel lateral beams of said frame.
Claim 7
Dependent Claim
31 words
A body support according to calim 3, in which said stringing is covered with a transparent covering foil which is likewise braced between said two parallel lateral beams of said frame.
