Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 is the flow chart for the CT data re-establishing method that the embodiment of the present invention one provides, and the present embodiment is applicable to utilize
The case where Pipeline technology rebuilds CT data, this method can be executed by CT data reconstruction device, the device
It can be realized by the way of software and/or hardware.As shown in Figure 1, this method specifically includes:
The initial data that S110, acquisition are obtained using CT scan, wherein initial data acquires data group by least one set
At, acquire data in be stored with acquisition parameter.
Wherein, initial data, which can be, scans the data directly obtained using CT equipment.According to CT equipment scanning mode
The acquisition modes of difference, initial data can be divided into two kinds, and one is axial scan acquisition modes, and one is helical scanning acquisitions
Mode.Wherein, axial scan acquisition modes specifically may is that whole process takes multiple scan, and during single pass, control
It is stationary to treat bed, the sonde rotary of CT equipment one week acquires corresponding data, i.e. single pass only acquires a detection
The data of device width.After the completion of present scan, Mobile treatment table, then scanned next time, entire initial data is by more
What secondary scanning was completed.And helical scanning acquisition modes specifically may is that whole process only carries out single pass, during scanning,
The detector of CT equipment does not stop to rotate, meanwhile, do not stop to rotate along with CT equipment, therapeutic bed is also constantly transported to specific direction
Dynamic, i.e., entire initial data is completed by single pass.
Wherein, acquisition parameter can be CT equipment when being scanned, the work of each related elements in set CT equipment
Make parameter, does not include corresponding checking list.For example, to can be bulb voltage, tube current, detector wide for acquisition parameter
Degree, detector swing circle, acquisition data number and scanned position.CT equipment is sweeping target patient using acquisition parameter
When retouching, the raw data of scanning corresponding with acquisition parameter can be accordingly obtained.In the present embodiment, it can preferably be stored with preset data
The raw data of every set acquisition parameter scanning corresponding thereto are saved as a complete data packet and collectively constitute one group by mode adopts
Collect data, is i.e. includes a set of acquisition parameter in every group of acquisition data.Wherein, default storage mode can be acquisition parameter and be stored in
Predeterminated position in corresponding acquisition data, the predeterminated position can be the head of acquisition data, be also possible to acquire the tail of data
Portion can also be the middle part of acquisition data, correspondingly, the raw data of scanning corresponding with acquisition parameter are then stored in acquisition data
In go out predeterminated position except other positions.Due to using acquisition parameter and scan raw data as a data packet not as
Different files are saved, so that acquisition can be called to join more conveniently during processing scans raw data
Number, while also saving the memory space of data.
During the entire process of being scanned using CT equipment to target patient, ray (such as can be X-ray, γ is penetrated
Line and ultrasound etc.) may coverage goal patient body different parts.Since the histoorgan of human body different parts is to ray
Susceptibility it is different, and in order to reduce the injury of ray dosage caused by human body as far as possible, it is therefore preferable that human body can be directed to
The difference of different parts histoorgan is adjusted correspondingly the dosage of ray in CT equipment.In the present embodiment, to CT equipment
The preferred embodiment that the dosage of middle ray is adjusted correspondingly can be, and use difference for the different parts of target patient body
Acquisition parameter be scanned, and due to the corresponding one group of acquisition data of a set of acquisition parameter, scan to obtain using CT equipment
Initial data in may include one group or multiple groups acquisition data.It should be noted that during actual scanning,
Acquisition parameter corresponding to human body different parts may be it is identical, still, since the human body of scanning is different, benefit
It is still different with the scan data that the identical acquisition parameter is got.The different parts of target patient body are directed to,
Identical acquisition parameter can correspond to multiple groups acquisition data.
S120, it is based on Pipeline technology, obtains checking list corresponding with acquisition parameter, and using checking list to original
Beginning data are corrected, the initial data after being corrected, wherein acquisition parameter is stored under the first store path, checking list
