Description

Medical film-shooting bed sickbed grid structure device

Technical Field

The utility model relates to an X-ray machine auxiliary assembly technical field especially relates to a medical film shooting bed sick bed grid constructional device.

Background

In medical diagnostic radiography, X-rays are directed from an X-ray source toward an object. When X-rays are used to create an image of an object, a portion of the direct radiation passes directly through the object, unaffected by the X-ray source, and into the X-ray detector to produce an image on X-ray film or other suitable detector. Some of the direct radiation is differentially absorbed by the object, creating a shadow of the object on the film or detector, and another portion of the radiation is scattered and reaches the X-ray detector at an angle that is significantly offset from its original path from the X-ray source. The scattered radiation causes "veil" superimposed on the absorption image, thereby reducing the contrast of the radiographic image. Radiation scatter can be reduced by using an X-ray grid. The anti-scatter grids in a grid are typically made of thin X-ray absorbing material arranged in a geometric pattern to absorb scattered radiation, and non-absorbing fibrous spacer material between the absorbing sheets allows direct radiation to pass through the radiation-shielding dispersion grid, the absorbing sheets are generally parallel to the direct X-ray beam emanating from the X-ray source, the focal length of the focus is typically fixed, and the relative positions of the X-ray source and the anti-scatter grid must be kept fixed to obtain acceptable radiographic results, thus inconveniencing manufacturing and use.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1, the medical radiography bed sickbed grid structure device of the present invention includes a grid structure body 1 having a longitudinal axis 2, the grid structure body includes a first cross member 3, a second cross member 4 and a plurality of absorption plates 5 substantially parallel to the longitudinal axis 2 and inclined to each other along the longitudinal direction to form a focus, the second cross member 4 is substantially parallel to the first cross member 3, the absorption plates 5 are connected at the corresponding top edge 6 and bottom edge 7 of each absorption plate 5 through the first cross member 3 and the second cross member 4, and a plurality of gaps 8 for receiving X-ray transmission are formed between the absorption plates 5. In this technical solution, the gap 8 is filled with air or fibrous spacer material. The first cross member 3 and the second cross member 4 are detachable. In one embodiment, the grid structure body is injection molded from an engineered thermoplastic material of high density particles for X-ray absorption, but with a sufficiently high yield strength suitable for X-ray applications and suitable for injection or compression molding using conventional equipment. Suitable high density particles for loading thermoplastic materials are known in the art and include, for example, lead, although non-toxic alternatives such as copper, tungsten, etc. may be suitably selected to avoid toxicity issues. Due to the increased yield strength provided by the engineering thermoplastic material, the grid structure is flexible and can be bent around an axis to adjust or change the focal length of the grid in one or more directions. For example, by bending the grid around an axis by substantially equal amounts, a substantially spherical focusing grid may be formed and used for some X-ray procedure. To accommodate different procedures, it may be bent in the opposite manner and returned to its previous form. It is envisaged that grids of different stiffness may be formed along predetermined axes to allow easier bending in one direction than in another, or to inhibit bending in a given direction but allow bending in other directions in order to achieve a desired focal length.

As can be seen from the above embodiments, the present invention has the advantages that:

the focusing focal length is variable, the relative positions of the X-ray source and the anti-scattering grid do not need to be kept fixed, and the manufacturing and the use are convenient.

The present invention has been described in detail with reference to the specific embodiments, but the present invention is not limited to the specific embodiments described above, and is only exemplary. Any equivalent modifications and substitutions are within the scope of the present invention for those skilled in the art. Accordingly, variations and modifications in equivalents may be made without departing from the spirit and scope of the invention, which is intended to be covered by the following claims.
