Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, it is more particularly related to a kind of wireless communication formula CT scan
Instrument.
Background technology
Be applied to since the beginning of this century it is clinical since, Cone-Beam CT is quickly grown, in future high-tech war, and field operation swashs
Dynamic Medical Devices are the important medical institutions of the wartime rescue and treatment of the wounded, are also the important medical part of disaster rescue.So
And field environment is disliked and omited, traditional huge CT scanner not only takes up space greatly, and can not be provided for urgent patient in good time
The other scan service of bed.
There are some miniaturization CT products at present, but employed the technology approximate with traditional CT bar none, such as dodged
The working method of bright bulk detector array, slip ring data transfer and helical scanning, and cross sectional reconstruction can only be carried out, all it is by X
Radiographic source and detector are fixedly installed on rotating disk, during turntable rotation, and detector receives and is perforated through human organ or tissue
The data of collection are carried out 3-dimensional reconstruction by X-ray afterwards by computer software.And in order to further embody facility
Property, the diagnostic function for adapting to CT scanner by the demand of future market, bed preferably makees corresponding extension, such as DR film makings, x perspectives, doctor
Life can select rational test mode according to the requirement of patient's detection position, inspection fee and image resolution ratio.
Furthermore, motion scan instrument exist it is many can be with improved place.Exemplified by the patent No. 201510627371, it is mainly
By reducing the volume, weight, the vibration amplitude for rotating radian and whole machine for reducing rotatable parts of CT scanner, whole machine is carried out
Improve, the drag chain part design part in the patent is the pioneering of research group, but also brings dynamically balanced ask simultaneously
Topic subtracts, it is necessary to eliminate the measures such as transmission eccentric force by balance correction to mitigate and eliminate the shock momentum of CT scanner itself
Few requirement to the ground that works.
The other CT scanner of bed has the features such as light weight, small volume, flexible movement, the other CT scan but existing market is gone to bed
