The utility model discloses a freely adjust of layer board angle, adjustment convenient and fast to can satisfy different inclination regulation requirements.
Description
Technical Field
The utility model relates to a medical treatment check out test set, concretely relates to a strutting arrangement that is used for CT image verification's phantom head, especially a strutting arrangement that is used for measuring CT phantom head of steerable support angle.
Background
The whole body phantom is a body model with the same height and weight as the real person, the size and the density of bones are similar to those of the real person, and the whole body phantom is provided with a radiating soft tissue substitute for verifying a CT image. Existing phantom head support devices, which typically have a fixed tilt angle, have difficulty interfering with their tilt angle through external controls.
For the whole body phantom, the gantry needs to be tilted when the head image is acquired. For example, when acquiring a head axial scan image, the frame is tilted because it is necessary to scan an image of a plane where the canthus lines (the line connecting the ear and the orbit) are located according to an application scene or a requirement of diagnosis by a doctor. The scanning is realized by adopting the existing phantom head supporting device, the frame needs to be inclined when scanning, so that the scanning time is prolonged, and the scanning personnel are not easy to find the canthus lines, thereby causing the need of rescanning.
Therefore, there is a need for a new phantom head supporting device, which solves the above problems by changing the angle of the phantom head.
Disclosure of Invention
The invention aims at providing a supporting device for a CT phantom head, which can adjust the inclination angle of the phantom head so as to avoid or reduce the inclination angle of a frame and shorten the scanning time.
In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows: the utility model provides a strutting arrangement for be used for CT phantom, includes support and layer board, rotate through the rotation axis of horizontal setting between layer board and the support and connect, fixedly connected with has 2 at least spinal branch posts on the layer board be equipped with between support and the layer board and be used for adjusting the layer board with the layer board angle adjustment mechanism of the relative angle of support.
In the technical scheme, the support is provided with a transverse plate and a vertical plate, the transverse plate and the vertical plate are fixedly connected or integrally formed to form an L-shaped structure, the top end of the transverse plate is an insertion end matched with a slot on a scanning bed, the rotating shaft is arranged at the upper end of the vertical plate, and the supporting plate angle adjusting mechanism is arranged on the vertical plate.
In the technical scheme, the support plate angle adjusting mechanism comprises a threaded rod and a knob fixed at one end of the threaded rod, a screw hole is formed in the vertical plate, the threaded rod is in threaded connection with the vertical plate through the screw hole, and the other end of the threaded rod abuts against the lower portion of the support plate.
In the above technical scheme, the pillar is 2, the pillar is connected with the layer board is perpendicular, and the position of pillar matches with the head jack of phantom.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
1. the utility model discloses be connected layer board and support through the rotation axis, realized the free regulation of layer board angle, simple structure easily realizes.
2. The utility model discloses in, stretch out the regulation of the length of support through the threaded rod, reach the purpose that the layer board gradient was adjusted, adjustment convenient and fast to can satisfy different inclination regulation requirements.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Wherein: 1. a rotating shaft; 2. a transverse plate; 3. a vertical plate; 4. a support plate; 5. a knob; 6. a threaded rod; 7. and a support pillar.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
the first embodiment is as follows: referring to fig. 1, the supporting device for the CT phantom with adjustable inclination angle comprises a transverse plate 2, a vertical plate 3 and a supporting plate 4, wherein the transverse plate 2 and the vertical plate 3 are fixedly connected or integrally formed to form an L-shaped structure. The top end of the transverse plate 2 is an insertion end matched with the slot on the scanning bed.
The upper end of the vertical plate 3 is provided with a rotating shaft 1, and the supporting plate 4 is rotatably connected with the vertical plate 3 through the rotating shaft 1. The supporting plate 4 is vertically connected with supporting columns 7, and the number, the position and the diameter of the supporting columns are matched with the jacks at the head of the phantom. Such as 2 struts in the figure.
The vertical plate 3 is provided with a screw hole, an angle adjusting piece is formed by a threaded rod 6 and a knob 5, the threaded rod 6 is in threaded connection with the vertical plate 3 through the screw hole, and the extending length can be adjusted by rotating the knob 5. The one end that threaded rod 6 stretches out riser 3 supports 4 below in the layer board, changes the angle of layer board through the extension length of adjusting the threaded rod.
As shown in the figure, the Z-axis direction is the horizontal movement direction of the scanning bed, the Y-axis direction is the direction vertical to the horizontal plane bed, and the X-axis direction is the direction horizontal to the scanning bed. The transverse plate 2 and the vertical plate 3 are vertically connected to serve as a supporting device, and the transverse plate 2 is inserted into a clamping groove of the scanning bed to play a role in fixing; the vertical plate 3 is connected with the supporting plate 4 through the rotating shaft 1 to play a role in rotation; the knob 5 and the threaded rod 6 form a knob device, and the length of the threaded rod 6 penetrating through the vertical plate 3 is changed by rotating the knob 5, so that the inclined angle of the supporting plate 4 is changed.
Therefore, the embodiment conveniently realizes the adjustment of the angle of the head of the phantom.
