Example 1
An embodiment of the present invention provides a novel X-ray dual-energy detector, please refer to fig. 1 and fig. 2, including: the device comprises a detection bottom plate 1, a detection small plate 2, a crystal structure 3 and a second filter 5; the detection small plate 2 is arranged on the detection bottom plate 1; the second filter 5 is arranged above the detection bottom plate 1, and a channel region is arranged on the second filter 5; thirty-two through holes 51 penetrating through the second filter 5 are formed in the channel area; the crystal structure 3 and thirty-two through holes 51 are correspondingly arranged on the detection small plate 2; the detection bottom plate 1 is used for transmitting detection data; the detection platelet 2 is used for collecting detection data; the second filter segment 5 is used for filtering the signal in the X-rays.
The crystal structure 3 includes at least thirty-two first crystals 31 and at least thirty-two second crystals 32; the first crystals 31 and the second crystals 32 are alternately arranged; the first crystal 31 and the second crystal 32 are correspondingly arranged on the detection small plate 2 corresponding to the channel region, and the second crystal 32 is correspondingly arranged below the through hole 51; the thickness ratio of the first crystal 31 to the second crystal 32 is 2-4: 1.
If the thickness of the X-ray irradiated crystal structure 3 after being filtered by the second filter 5 is consistent with that of the X-ray irradiated crystal structure 3 after being not filtered by the second filter 5, the overflow of the low-energy sampling value is easy to occur, then the crystal structure 3 is changed into a structure formed by a first crystal 31 with high thickness and a second crystal 32 with low thickness, and the second crystal 32 with low thickness is arranged below the through hole 51, so that the overflow of the low-energy sampling value can be effectively reduced.
In order to prevent overflow of the sampled values impinging on the crystal structure 3, a first filter 4 is arranged below the second filter 5; first filter 4 and second filter 5 are the brass material.
A first filter 4 is arranged between the crystal structure 3 and the second filter 5; the thickness of the first filter 4 is lower than that of the second filter 5; the X-rays irradiate on the second filter 5, and since thirty-two through holes 51 are formed in the second filter 5, a part of the X-rays pass through the through holes 51 and irradiate on the first filter 4; the X-ray after filtering through first filter 4 and second filter 5 irradiates to crystal 3 on, can obtain X-ray's high energy and low energy sample data respectively, wherein the X-ray through-hole 51 and first filter 4 shines the low energy sample data that obtains on crystal 3, and the X-ray through first filter 4 and second filter 5 shines the high energy sample data that obtains on crystal 3.
The first filter 4 is arranged at the position of 0.5-2.5 mm on the first crystal 31; the first crystal 31 and the second crystal 32 comprise one of CsI, CWO, GOS, GAGG.
Four connecting columns 6 are arranged on the detection bottom plate 1; the detection small plate 2, the first filter 4 and the second filter 5 are connected through a connecting column 6; a pin flat cable is arranged between the detection bottom plate 1 and the detection small plate 2 and is used for transmitting detection data.
Because the number of the through holes formed in the second filter sheet is thirty two, the novel detector can only receive data of thirty-two channels, including a high-energy thirty-two channel and a low-energy thirty-two channel, and the lost data of the high-energy thirty-two channel and the low-energy thirty-two channel needs to be interpolated and compensated by the compensation formula with the help of the obtained data of the high-energy thirty-two channel and the low-energy thirty-two channel, that is, as shown in fig. 3, the data of the first channel and the third channel are both low-energy data, the data of the second channel is high-energy data, and the lost low-energy data of the second channel is interpolated and compensated by averaging the low-energy data of the first channel and the third channel, and similarly, the lost high-energy data can also be interpolated and compensated.
Example 2

s100, emitting X-rays:
send X ray to second filter 5 through the X ray transmitter, X ray shines on second filter 5, because 32 through-holes have been seted up on second filter 5, so X ray divide into two parts, and partly 32 through-holes 51 direct irradiation on first filter 4 on through second filter 5, and another part does not shine on first filter 4 through-hole 51 on second filter 5, and the X ray of last two parts all can shine on crystal structure 3.
S200, X-ray energy splitting:
the response value of the X-ray is divided according to the position of the X-ray irradiated on the crystal structure 3.
If the X-ray is transmitted to the first crystal 31 after being irradiated on the first filter 5, the response value of the part is high energy;
if the X-ray is transmitted to the second crystal 32 after being irradiated on the second filter 4 through the through hole 51 of the first filter 5, the response value of the portion is low.
The detecting small plate 2 obtains a plurality of low energy values and a plurality of high energy values and sends the low energy values and the high energy values to the detecting bottom plate 1 through pin flat cables.
S300, data processing:
s301, data acquisition:
several low energy values and several high energy values transmitted by the probe platelet 2 are obtained, several low energy values being combined into a first data set and several high energy values being combined into a second data set.
S302, data transmission:
the first data set and the second data set are sent to the background upper computer through the detection bottom plate 1, and the background upper computer processes and displays the first data set and the second data set.
S303, data compensation:
and according to the first data set and the second data set, low-energy data which correspond to the channel missing are obtained through a first formula, and high-energy data which correspond to the channel missing are obtained through a second formula.
The first formula:
the second formula:
where i is the number of the channel, it should be noted that the number starts from 0 according to the numbering rule in the computer.
For more clearly explaining the present invention, i =1 is set to represent the second channel, and in the actual detection process, the second channel can obtain a high energy value, and then a low energy value of the second channel needs to be obtained by a first formula, that is, after the low energy value of the first channel and the low energy value of the third channel are summed, an average value of the sums is obtained, which is a low energy value of the second channel; setting i =2 to represent the third channel, and in the actual detection process, if the third channel can obtain a low energy value, the high energy value of the third channel needs to be obtained by a second formula, that is, after the high energy value of the second channel and the high energy value of the fourth channel are summed, an average value of the sums is obtained, which is the high energy value of the third channel.
It should be noted that the above-mentioned setting is only for explaining the present invention, and the protection scope of the present invention is not limited thereby.
