Abstract

The utility model discloses a separable high-low energy X-ray detector, which comprises a low-energy detector and a high-energy detector, wherein the high-energy detector is arranged below the low-energy detector; a filter plate is arranged between the high-energy detector and the low-energy detector and is also arranged at the bottom of the low-energy detector. In the utility model, the high-energy detector and the low-energy detector are assembled into the high-low energy detector, so that the damaged detector can be directly replaced without scraping the other undamaged detector.

Description

A kind of separable high and low power X ray detector

Technical field

The utility model relates to a kind of X-ray detector, refers to a kind of high energy detector and the separable X-ray detector of low energy detector especially.

Background technology

At present, X-ray detector is generally all formed by high energy detector and the integrated making of low energy detector, because a filter need be set between high energy detector and low energy detector, in order to reduce the volume of high low energy detector, the effect of while in order to guarantee to filter, often use highdensity tungsten sheet etc. as filter, so increased cost; Two come in use, in case find a for example high energy detector or a damage of low energy detector in the high low energy detector, all must change whole high low energy detector, so just cause great waste, can continue to use less than damaging because also have a detector after all.

The utility model content

The purpose of this utility model provides a kind of separable high and low power X ray detector, high energy detector and low energy detector set are dressed up high low energy detector, as long as wherein there is a detector to damage, just can directly change like this, and not need to scrap the detector that another one does not have damage.

In order to achieve the above object, the utility model is achieved by the following technical solution:

A kind of separable high and low power X ray detector, comprise a low energy detector, a high energy detector, described high energy detector is arranged on described low energy detector below, be provided with a filter between described high energy detector and the described low energy detector, described filter is arranged on the bottom of described low energy detector or the top that described filter is arranged on described high energy detector.

Further, described low energy detector comprises a board layer, is arranged on the silicon wafer layer on the board layer, is arranged on the detecting layer on the silicon wafer layer, and described board layer is drawn two array of pins lead-in wire downwards; Described high energy detector comprises a board layer, be arranged on board layer below silicon wafer layer, be arranged on the detecting layer of silicon wafer layer below, described board layer is drawn two array of pins lead-in wire downwards.

Further, the filter of this patent is a copper sheet.

The utility model will be independently the low energy detector be assembled into high low energy detector with high energy detector, volume is not excessive owing to not needing to consider integrated design again, so just can use copper sheet as filter, thereby reduce cost.The purpose of this patent design just is that incorporate device is designed to two independent device to assemble, and so wherein any one device damages, if replace just passable, thereby saved cost greatly, avoided waste.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified

As shown in Figure 1, a kind of separable high and low power X ray detector, comprise a low energy detector 9, a high energy detector 10, high energy detector 10 is arranged on low energy detector 9 belows, be provided with one between high energy detector 10 and the low energy detector 9 and filter copper sheet 4, filter copper sheet 4 and be arranged on the bottom of low energy detector 9 or the top of high energy detector 10.

Low energy detector 9 comprises a board layer 3, is arranged on the silicon wafer layer 2 on the board layer 3, is arranged on the detecting layer 1 on the silicon wafer layer 2, and board layer 3 is drawn two array of pins lead-in wire 8 downwards; High energy detector 10 comprises a board layer 5 too, be arranged on board layer 5 belows silicon wafer layer 6, be arranged on the detecting layer 7 of silicon wafer layer 6 belows, board layer 5 is drawn two array of pins lead-in wire 8 downwards.

Those skilled in the art will recognize that; above-mentioned embodiment is exemplary; be in order to make those skilled in the art can better understand this patent content; should not be construed as is restriction to this patent protection domain; change or modify so long as disclose spiritual any being equal to of being done, all fall into this patent protection domain according to this patent.
