Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, it is more particularly related to a kind of with DR film making function
CT scanner.
Background technique
In China, as national health demand constantly increases, central nervous system disease development is fast in addition, and the state of an illness is critical,
The patient for carrying out head CT scan is needed increasingly to increase because of brain diseases every year.Currently, needing to carry out brain scans every year
There are about 20,000,000.However, by some patients being in a bad way be sent to CT Room be scanned check it is abnormally dangerous in addition can not, because
For when transferring patient to CT Room, it is often necessary to be forced to temporarily cease making for various important physiology monitorings and some crash equipments
With this is possible to making patients' state of an illness or leads to the generation of complication, and is difficult to provide in due course monitoring in change of illness state
With treatment measure.Therefore, it is badly in need of a kind of small-sized movable CT scanner and scan service by due course bed is provided for urgent patient, keeps away
Exempt from the danger of delay diagnosis.
Mobile CT scanner is the big innovation in CT history in recent years.NeuroLogica company of the U.S. released in 2005
The first movable bed in the world by CT scanner-CereTom, providing in places such as ward, emergency ward, ICU severes is patient
The service for carrying out diagnosis and treatment, realizes method of service focusing on people, represents a developing direction in CT scanner future.Cause
Its novelty outstanding, CereTom obtain the Frost&Sullivan medical image product invention prize in 2006 years, and
The medicine design gold medal in 2006 years.
Had several Mobile CT instrument products at present, but bar none use with the approximate technology of traditional CT, such as
The working method of scintillator detector array, the transmission of slip ring data and helical scanning, and can only carry out cross sectional reconstruction, be all by
X-ray source and detector are fixedly installed on turntable, and in turntable rotary course, detector reception is perforated through human organ or tissue
X-ray afterwards carries out 3-dimensional reconstruction by data of the computer software to acquisition.And in order to further embody convenience
Property, the demand of future market is adapted to, the diagnostic function of CT scanner is preferably made to extend accordingly by bed, such as DR film making, x perspective, doctor
Life can select reasonable test mode according to the requirement of patient's detection position, inspection fee and image resolution ratio.
The other CT scanner of bed has the characteristics that light weight, small in size, flexible, the other CT scan but existing market is gone to bed of movement
Instrument medical diagnosis function is relatively simple, can only carry out CT scan detection to patient, not have DR film making function, so that patient needs
Toss about multiple sensing chamber to complete required detection information, inconvenience is brought to patient, especially to not easily shifted weight
Disease patient needs a kind of multi-functional CT scanner to facilitate and carry out multinomial detection.

Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art referring to specification text
Word can be implemented accordingly.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of a other elements or combinations thereof.
As shown in figs. 1-12, the present invention provides a kind of CT scanner with DR film making function, comprising:
Turntable 1 is connect with the rotary driving part being mounted on CT scanner；The turntable 1 is set in the present embodiment
It sets on the rack, and can be freely rotated on the rack, rack two sides are flat by the lifting that the CT scanner is arranged in bracket 4
On platform 5, while rack lower end being provided with synchronous pulley 6, synchronous pulley 6 is connect by synchronous belt with turntable 1, thus together
Step belt wheel 6 drives turntable 1 to realize forward and reverse on the rack, completes CT scan process, as depicted in figs. 11-12.
X-ray source component 2 is mounted on the lateral wall of the turntable 1 and can rotate on the turntable 1, the x
The outgoing beam of radiographic source group 2 towards the turntable axis center, specifically, 2 one end of x-ray source component pass through rotation axis rotate
It is connected on the lateral wall of turntable 1, pushes the other end of x-ray source component 2 to exist around the rotation axis of the other end by driving mechanism
It is rotated on the lateral wall of turntable 1, so as to adjust the shooting angle of x-ray, meanwhile, at the radiation exit of x-ray source component 2
It is provided with beam-defining clipper 7, as shown in Figure 4；And
Detector assembly 3 is mounted on on obverse 1 lateral wall of turntable of the x-ray source component 2, is used for
It receives and passes through patient body x-ray from what x-ray source component 2 was emitted, so that effective information is extracted, CT scan function of the invention
The half fan-delta sandbody mode that inclination x-ray source can be added using offset flat-panel detector, as shown in Figure 1, by adjusting x-ray source group
The angle of 2 emergent ray of part, while translating detector assembly 3 makes its holding that can receive the emergent ray of x-ray source component 2, is used for
CT scan imaging, in a first aspect, DR film making function irradiates projection pattern using x-ray source and the vertical face of flat panel detector, such as

Through the x-ray after human organ or tissue, 3-dimensional reconstruction is carried out by data of the computer software to acquisition.It is this
Detector and x-ray emission source limit the application range of CT scanner, are only used for CT scan, and in the present invention, it uses
Plate detector, along with more in the prior art smaller in the focal plane of x-ray source, pixel is higher, is imaged more clear
It is clear, so that DR film making and perspective function may be implemented when x-ray source and the vertical positive control of flat panel detector, meanwhile, using inclined
Horizontalization partitioned detector adds half fan-delta sandbody mode of inclination x-ray source that can complete CT scan process, is penetrated using the x of inclination installation
Line source increases detector to the distance of x-ray source rotation center, thus actually increase scanning internal diameter, scanner scanning one week
Entire three-dimensional reconstruction process can be completed, and scanning range is bigger, to reduce the radiation, x-ray amount to patient, further
Ground can increase the scanning holes internal diameter of scanner on the basis of keeping original scanner size, convenient to there is auxiliary monitoring to rescue
Protect the scanning of the patient of instrument.
