Description
Technical field
The utility model relates to the field of medical instrument technology, in particular to a kind of CT scanner.
Background technique
Computed tomography (CT) imaging technique is born in nineteen seventies, is one of four big image technologies,
It since such technology has many advantages, such as that imaging time is short, high resolution, and contains much information, clinical application is very extensive.
However, environmental radiation dose is high since large-scale CT scanner is bulky, heavy, special shielding room is needed,
It is difficult to meet the needs of many special applications, for example, salvage grave patients need to be transported to CT Room from ward for salvage grave patients of being hospitalized
It is checked, in the process, the serious medicals risks such as bleeding, de- pipe, cardiopulmonary arrest is easy to happen, if can be by CT scan
Instrument, which moves on to ward and is scanned, will greatly avoid medical-risk；For another example, for the patient of field rescue, such as earthquake or traffic accident
In Patients With Brain Injury, golden hour only has half an hour, if CT scanner can be transported to accident or disaster field, and
The death rate will be effectively reduced in Shi Jinhang diagnosing and treating.
Therefore, clinical diagnosis and treatment need a kind of small-sized movable CT scanner small in size, light-weight, moveable, can
Emergency ward, ward use, can also be vehicle-mounted, carrier-borne and airborne, meet field treatment demand, by the method for service of CT scanner by
" centered on instrument " is changed into " human-centred ".
It please join shown in Fig. 1 and Fig. 2, a kind of prior art discloses a kind of mobile CT scanner, x-ray source 10 and detector
12 on the turntable 14, and slip ring 16 is by electric energy required for the x-ray source 10 and the equal components of detector 12 on turntable 14 from static
Rack be transferred on turntable 14 by brush and slideway.Detector 12 obtains data for projection, and by being mounted on slip ring 16
High speed data transfer module be transmitted to the industrial personal computer 13 of CT scanner bottom, image weight is carried out according to data for projection by industrial personal computer 13
It builds, then the faultage image after reconstruction is transmitted to mobile workstation (not shown), used for doctor.
It, need to be in industry control to improve image reconstruction speed, shortening period of reservation of number since the calculation amount of image reconstruction is very big
Video card and mainboard etc. are installed in machine 13, accelerated by parallel computation.Since industrial personal computer 13 is placed on mobile CT scanner
Bottom will increase the axial length of mobile CT scanner if industrial personal computer and electrical system are horizontal positioned, if industrial personal computer and electrical system
System is placed up and down, will increase the height of mobile CT scanner.These increased sizes will lead to mobile CT scanner some narrow
Small space is inconvenient to use, influences the application and popularization of mobile CT scanner.In addition, being mounted on the high-speed data on slip ring 16
Transmission module expense is very expensive, and relies primarily on import at present, so that entirely mobile CT scanner is expensive, is unfavorable for
The application of CT scanner.
Therefore, a kind of CT scanner need to be provided, to solve the above-mentioned technical problems in the prior art.
