Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment：One kind for remote radiotherapy apparatus output measurement Water ball, its structure as Figure 1-5, including：Case
Body 1, the top of casing 1 has and has an ionisation chamber jack 6 in groove 2, casing 1, the case of the one side relative with ionisation chamber jack 6
The sidepiece of body 1 has water filling knob 3, and the bottom of casing 1 has the knob 5 that discharges water, wherein：
The bottom of the casing 1 also has the first degassing button 4-1 and the second degassing button 4-2.
The inside of casing 1 has dividing plate 11, and box house is divided into the first cavity volume 7-1 and the second cavity volume 7-2 by dividing plate 11, electricity
Outer wall from room jack 6 is located in the first cavity volume 7-1.
There is lug boss 8, lug boss 8 is located in the second cavity volume 7-2 on the bottom of the dividing plate 11, have on lug boss 8 and use
In the through hole 9 of connection the first cavity volume 7-1 and the second cavity volume 7-2；
There is the concave part 10 for accommodating lug boss 8 on the knob 5 that discharges water.From the point of view of control is facilitated,
Discharge water the outside of knob 5 and the bottom formation screw thread cooperation of casing 1, the inner side of knob 5 and the outside of the lug boss 8 formation screw thread of discharging water
Coordinate so that the knob 5 that discharges water can be used to control the break-make of the first cavity volume 7-1 and the second cavity volume 7-2.
Casing 1 is seen on the whole, is rectangular structure, and the top surface of casing 1 and bottom surface are square, and long and width is
200mm, 110mm high, surrounding wall thickness are 10mm, and casing 1 and dividing plate 11 are lucite material, the height of the second cavity volume 7-2
It is 15mm, the distance of bottom surface of the ionisation chamber jack 6 away from groove 2 is 5cm, and the depth of groove 2 is 2mm.
The ionisation chamber jack 6 is cylinder, and the wall thickness in the outside of ionisation chamber jack 6 is no more than 1.5mm, can be at utmost
The conversion for reducing water and lucite.The centre of ionisation chamber jack 6 is the less structure of internal diameter, it is possible to reduce probe and ray
Between unnecessary obstruct, make measurement more preferably close to actual conditions.
In the present invention, the design of groove 2 is able to use two kinds of reports.When increase is onesize on groove 2
Glass when, go for No. IAEA-277 report.IAEA-277 reporting requirements fill the die body of water from ionization locular wall to
The distance of upper surface is equal to 5.18cm under water.When being not added with glass, go for No. IAEA-398 report.No. IAEA-398 report
Accuse require to fill the die body ionisation chamber geometric center of water to the distance of upper surface be 5cm.
The use process and principle of the present apparatus be：
Using preceding, it is necessary to carry out water filling.With reference to shown in Fig. 1, by 90 ° of its rotate counterclockwise, make water filling knob 3 be in and most push up
Portion, then removes water filling knob 3.With reference to shown in Fig. 6, added water from water filling port, then water begins to irrigate the first cavity volume 7-
1.Then, loosen or remove the first degassing button 4-1 and the second degassing button 4-2, then the second cavity volume 7-2 tops just turn into it is outer
Connect the structure for communicating.The knob 5 that discharges water is rotated again, it is displaced outwardly, but does not depart from casing 1, then the two ends of through hole 9 are to be led
Logical, water just flow to the second cavity volume 7-2 from the first cavity volume 7-1 via through holes 9.Because the diameter of through hole 9 is smaller, the first cavity volume
The filling speed of 7-1 reclaimed waters, the rate of climb of the second cavity volume 7-2 reclaimed waters is slower.Then when water reaches the second cavity volume 7-2 entirety
When the half of height is to 3/4ths, the first degassing button 4-1 and the second degassing button 4-2 is screwed, then in the second cavity volume 7-2 just
Partial air is provided with, and the partial air cannot flow out from the second cavity volume 7-2.It is further continued for adding water, until the first cavity volume 7-1
Fill it up with, and water filling knob 3 of screwing on again.
Turn clockwise 90 °, then casing 1 shows the state shown in Fig. 1 again.Now, the water in the second cavity volume 7-2, just
Top in the second cavity volume 7-2, is adjacent to the lower surface of dividing plate 11, and the first cavity volume 7-1 and the second cavity volume 7-2 is in connected state
State.
In detection process, if the coolant-temperature gage inside casing 1 is significantly raised, the volume of water will expand, and then extrude
The volume of air, realizes relative equilibrium in second cavity volume 7-1.Coolant-temperature gage inside casing 1 declines to a great extent, then the volume of water is just
Can diminish, air will occupy the volume fractiion of water after reducing.Because the water in the first cavity volume 7-1 and the second cavity volume 7-2 is in
Connected state, can be considered as an entirety, so temperature conduction is visibly homogeneous, then the volume of the water of whole box house and air
Change is at relative balance state, and then prevents from damaging casing because water expands with heat and contract with cold.
Because different accelerator calibrating standards is different to the requirement for fathoming, the present invention is arrived to ionisation chamber
The distance on surface is optimized design, realizes adapt to the effective measurement point of ionisation chamber simultaneously centered on, 0.6r and 0.75r etc. three
Plant measuring method.
In the present invention, the design of groove 2 is able to be applicable different calibrating standards.Although PMMA and water very close to,
But the density of water is different.The accurate absorption coefficient difference for calculating PMMA and water during design so that ionisation chamber is arrived on surface
Distance is water equivalent distances.
The present invention is also claimed application of the above-mentioned anti-expansion Water ball in radiotherapy detection work.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or uses the present invention.
Various modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, the present invention
The embodiments shown herein is not intended to be limited to, and is to fit to consistent with principles disclosed herein and feature
Scope most wide.
