At the same time, this sagging also makes it difficult to keep the bed board itself level
[0004] This kind of sagging will not only affect the scanning effect, but also cause discomfort to the patient in severe cases.

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] figure 2 is a schematic diagram of a scanning couch 1 according to a preferred embodiment of the present invention. Such as figure 2 As shown, a scanning couch 1 may include a couch 10 , a linear motion device 11 , a couch support 12 and wheels or bearings 14 , which together support a patient 13 . Wherein, the linear motion device 11 is used to guide the bed board 10 to move linearly, and the bed frame 12 is used to support the bed board 10 and the linear motion device 11 .

[0035] It should be noted that figure 2 For illustration only. According to different embodiments of the invention, the scanning couch 1 may have more or fewer components.

[0036] as previously referenced figure 1 As mentioned above, in the prior art, the sagging of the bed board makes it difficult to keep the bed board itself level. For example, in fig...

Abstract

The invention provides a scanning bed and a computed tomography (CT) system or a positron emission tomography (PET) system containing the scanning bed. The scanning bed comprises a bed plate, a linear motion device and a bed support, wherein the bed plate comprises a pre-deformation plate, the pre-deformation plate has pre-deformation, under the condition that actual load is exerted, and the direction of pre-deformation and the pre-deformation plate can produce opposite deformation directions. The linear motion device is used for guiding the bed plate to conduct linear motion, and the bed support is used for supporting the bed plate and the linear motion device. The bed plate can obviously reduce drooping and / or inclination of the bed plate of the scanning bed, shortens the range of deformation of the bed plate, and reduces vibration range of the bed plate, and the range of the deformation of the bed plate is caused by different weights of patients. In addition, the scanning bed has the advantage of being low in achieving cost.

Description

technical field [0001] The present invention relates generally to tomography, and more particularly to a scanning couch and a computed tomography (CT) system or positron emission tomography (PET) system including the same. Background technique [0002] figure 1 is a schematic diagram of a prior art scanning table 1'. The scanning bed 1' includes a bed board 10', a linear motion device 11' and a bed support 12', which jointly support a patient 13'. [0003] from figure 1 As can be seen in the currently developed hybrid scanning bed 1' (which can be used for CT or PET), during the scanning process (such as figure 1 As shown in the middle left, middle and right pictures, the left picture is the starting stroke position, the middle picture is the middle stroke position, and the right picture is the entire stroke position), affected by the weight of the patient 13', the bed board 10' will have a large sagging (in figure 1 expressed in dH). The overall sag of the deck comes ...
