Embodiment 1
Referring to FIG. 1 to FIG. 3, a kind of radiation therapy bed equipped with N cable architecture, it is characterised in that:
Including bed board 1, developing apparatus；The developing apparatus is fixed using N cable architecture 4 made of non-magnetic material
In the bottom surface of the bed board 1；
The N cable architecture 4 includes the oblique line 4-1, several of a reference line 5, the several segments known length being parallel to each other
Mark line 6；The ipsilateral starting point of several segments oblique line 4-1 is uniformly connected to formation M intersection point on the reference line 5 respectively, if described
The length of dry section oblique line 4-1 is successively successively decreased；The other end of several segments oblique line 4-1 connects one to one parallel with reference line 5 respectively
Several mark lines 6 one end formed P intersection point；Outermost mark line is arranged symmetrically with reference line 5, the other end of remaining mark line
It is flushed with the respective end of reference line 5；
There are density variations for the material of the material of the N cable architecture 4 and bed board 1.
Referring to fig. 4 and Fig. 5, in this case mark line 6 design, be to be considered based on following: if lesion falls in top first
When on section oblique line 4-1, then imaging point can be formed when profile scanning on mark line 6, it is assumed that the imaging point is recorded as O1；If fallen
On second segment oblique line, then O can be respectively formed on two mark lines 6 when profile scanning1、O2Two imaging points, and so on,
The imaging point that intersection point to be fallen on mark line 6 by profile scanning is formed judges which section oblique line is the lesion be to facilitate
On.
Further, the angle of oblique line 4-1 described in this example and reference line 5 is 45 °, and 45 ° of angles are used in this example, are to make
The P intersection point of this section of oblique line to reference line 5 vertical line length=this section of oblique line M intersection point to the vertical line vertical range,
To form isosceles triangle convenient for calculating.For example, allowing patient to lie low when operation and doing CT scan on radiation therapy bed, work as affected area
In in the region of N cable architecture 4, the CT of top carries out tomoscan, can be developed according to CT bidimensional image, also that is, obtaining
The X, Y coordinates of lesion.Shown in CT scan Fig. 4 when a point of expression lesion, the imaging of CT tomography surface sweeping shown in fig. 5 is obtained
Point, the O formed according to profile scanning mark line 61、O2Two imaging points, it is oblique to judge that a point is located at second segments several from top to bottom
On line, the distance of M intersection point to the bottom end of reference line 5 on second segment oblique line is fixed length L, the distance, delta of actual measurement reference line 5 to a point
T, due to for isosceles right triangle, so a point lesion is so the vertical range of M intersection point to the vertical line of oblique line is also Δ
T, therefore the longitudinal coordinate Z=L+ Δ t of a point, are achieved with the three-dimensional coordinate of lesion, Δ t can be with manual measurement descendant here in this way
Work calculates, can also be by intelligent measure equipment automatic measurement after, automatic calculate obtains.
Further, the M intersection point of previous oblique line 4-1 in two of the arbitrary neighborhood oblique line 4-1 and latter item are oblique
The line of the P intersection point of line is perpendicular to reference line 5, in this way in tomoscan, the interruption between adjacent oblique line would not occurs, sweep
What is be connected when retouching is relatively good.
Further, the bed board 1 uses nonmetallic materials.Carbon fiber and foam can be used in nonmetallic materials in this example
Composite material or POM material or the Lightweight nonmetals material such as PC material or ABS material.
Further, the N cable architecture is made of carbon fiber or rigid foams or non-magnetic aluminum strip.
Further, the N cable architecture 4 is embedded in the bottom surface of the bed board 1.
Further, the two sides of the bed board are also symmetrically arranged with side plate, and the side plate is equipped with hand hole, facilitates manpower
It holds and moves.
Further, the side plate is arc-shaped, the arc-shaped shape for more agreeing with human body in both sides.
Further, the vertical view of the bed board is in the shape for agreeing with human body outer profile.
The above-mentioned description to embodiment is for the ease of those skilled in the art it will be appreciated that and using this
Case technology, person skilled in the art obviously can make various modifications to these examples easily, and described herein one
As principle be applied in other embodiments without having to go through creative labor.Therefore, this case is not limited to above embodiments, ability
The technical staff in domain according to the disclosure of this case, the improvement made for this case and repair this all should be in the protection scope of this case.
