Patient support device with low attenuation properties
View Patent ↗A patient support device for a radiation therapy treatment system and a method of manufacturing the same. The device includes a support having an upper surface and a lower surface and a fixture hole configuration that receives a patient fixation device. The fixture hole configuration includes at least one recess and reinforcing material positioned inside at least a portion of the at least one recess. The device may also include a lower support having an upper surface that includes at least one channel. Flat flex cable used to operate the patient support device is positioned within the at least one channel.
1. A patient support device for a radiation therapy treatment system, the device comprising:
a support having an upper surface facing a patient when the patient is positioned on the patient support device, the upper surface including at least one channel for wiring used to operate the patient support device, the channel including two sidewalls and a bottom wall and wherein at least one of the two sidewalls intersects the bottom wall at an obtuse angle in order to reduce or eliminate attenuation of a radiation beam.
2. The patient support device of claim 1 , wherein the at least one channel has a depth approximately equal to a thickness of an electrical conductor positioned within the at least one channel.
3. The patient support device of claim 2 , wherein the electrical conductor includes a flat flex cable.
4. The patient support device of claim 1 , wherein the obtuse angle is from approximately 135 degrees to approximately 179 degrees.
5. The patient support device of claim 1 , wherein at least one of the sidewalls directs a radiation beam aimed along the sidewall outside a patient treatment area of the patent support device.
6. The patient support device of claim 1 , wherein the at least one channel extends down a length of the support.
7. The patient support device of claim 1 , further comprising an upper support movable with respect to the first support and controlled by the wiring.
8. The patient support device of claim 7 , further comprising a bearing layer between the upper surface of the first support and a lower surface of the upper support.
9. The patient support device of claim 1 , wherein the wiring is adhered to the bottom wall.
10. The patient support device of claim 1 , wherein the at least one channel includes a first channel and a second channel and wherein wiring included in the first channel includes wiring conveying power and wiring included in the second channel includes wiring conveying data.
11. A patient support device for a radiation therapy treatment system, the device comprising:
a support having an upper surface facing a patient when the patient is positioned on the patient support device, the upper surface including at least one channel and flat flex cable used to operate the patient support device positioned within the at least one channel, wherein the at least one channel includes two sidewalls and a bottom wall and wherein at least one of the two sidewalls intersects the bottom wall at an obtuse angle in order to reduce or eliminate attenuation of a radiation beam.
12. The patient support device of claim 11 , wherein the at least one channel has a depth approximately equal to a thickness of the flat flex cable.
13. The patient support device of claim 11 , wherein the obtuse angle is from approximately 135 degrees to approximately 179 degrees.
14. The patient support device of claim 11 , wherein at least one of the two sidewalls directs a radiation beam aimed along the sidewall outside a patient treatment area of the support.
15. The patient support device of claim 11 , wherein the at least one channel extends down a length of the support.
16. The patient support device of claim 11 , further comprising an upper support movable with respect to the first support and controlled by the flat flex cable.
17. The patient support device of claim 16 , further comprising a bearing layer between the upper surface of the first support and a lower surface of the upper support.
18. The patient support device of claim 11 , wherein the flat flex cable is adhered to the at least one channel.
19. The patient support device of claim 11 , wherein the at least one channel includes a first channel and a second channel and wherein wiring included in the first channel includes wiring conveying power and wiring included in the second channel includes wiring conveying data.
