Method be matched using sodium iodide crystal (NaI) with photomultiplier tube (PMT), or directly using Geiger counter come to patient into
Row monitoring.But the PMT or Geiger counter that this method uses be required to it is hundreds of lie prostrate to obtain high pressure, and volume is larger (such as general
PMT, diameter 5cm, length is in 10~15cm, then matches the electronic circuit plate of corresponding processing signal, entirely pops one's head in
Generally in 20cm or so, this is allowed for when monitoring patient procedure length, in order to guarantee that measurement accuracy, equipment use machinery mount
It fixes, patient will keep posture not change；Except this, after the treatment, can generally go back home patient middle recuperation, at this time because in vivo still
There is a large amount of radiopharmaceutical, not can contact infants and children still, but because equipment is inconvenient to carry, and price is higher, is each
Patient wears a radiacmeter, also unrealistic.Therefore the currently, monitoring of the residual activity of the patient after radiation treatment
It is still one without preferably solving the problems, such as.

Pipe) instead of traditional PMT, so that its operating voltage, power, volume, many aspects such as weight all meet portable device
Demand.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: a kind of based on the portable of SiPM
The probe of thyroid function meter, including radiation probe, silicon photomultiplier, pre-amplification circuit plate and shell, radiation probe be
Hollow cylindrical body is sealed with LYSO crystal, the rear end of silicon photomultiplier and an end face phase of radiation probe in cylindrical body
Even, the pin of silicon photomultiplier is connected with the input terminal of pre-amplification circuit plate, is provided in the middle part of pre-amplification circuit plate
With the aperture of silicon photomultiplier similar shape, silicon photomultiplier is set in aperture, and shell includes fixing piece and cover board, fixing piece
Be provided with the cavity with radiation probe similar shape, radiation probe is arranged in cavity, fixing piece, pre-amplification circuit plate and cover board according to
It is secondary to be fixedly linked.
Further, the edge profile of the fixing piece, the end face of the pre-amplification circuit plate and the cover board end face
It is that round and size is identical.
Further, the end face diameter of the radiation probe be 15mm, the radiation probe with a thickness of 10mm.
Further, the optical window of the silicon photomultiplier is end-window, and the size of optical window is 3mm × 3mm.
Further, one layer of heat conductive silica gel is additionally provided between the pre-amplification circuit plate and the cover board.
Further, the rear end of the silicon photomultiplier and an end face of the radiation probe pass through photoconductive resin glue phase
Even.
Further, the edge of the fixing piece, the pre-amplification circuit plate and the cover board is uniformly surrounded with 6
Diameter is the through-hole of 2mm.
The utility model has the beneficial effect that the utility model is small in size compared with prior art, easy to carry, function
Consume it is low, can be used storage battery power supply be not required to fix to guarantee that patient in iodine -131 therapeutic process, can arbitrarily put posture
In the designated position of large scale equipment；The utility model can be adhered directly to patient skin surface, it ensure that the opposite patient that pops one's head in
Between position be it is indeclinable, measurement result is accurate；After patient's treatment, the utility model can be carried and go home to be monitored,
Make patient that can know in real time the radioactive activity of oneself, to avoid and pregnant woman or child getting in contact.
