Detailed description of the invention
In order to provide the implementation of the CT image obtaining high-quality enhanced ct scans, embodiments provide one
The method of adjustment of the delayed sweep time of enhanced ct scans and device, below in conjunction with Figure of description to the preferred embodiments of the present invention
Illustrate.
The method of adjustment flow chart of the delayed sweep time of the enhanced ct scans that Fig. 1 provides for the embodiment of the present invention, including:
101: the delay very first time carries out current CT scan, shows DICOM (the Digital Imaging of current CT scan
And Communications in Medicine, digital imaging and communications in medicine) image.
Enhanced ct scans generally includes repeatedly CT scan, after the current CT scan required very first time postponed determines, postpones the
One time carried out current CT scan.The current CT scan required very first time postponed, can be that operator are to current CT scan
The time delay of initial setting up, the time delay not the most being adjusted；Can also be that operator adjust according to actual needs
After time delay.I.e. the very first time be it has been determined that current CT scan needed for delay time.
If current CT scan is the first time CT scan of enhanced ct scans, then postpone the very first time refer to intravenous injection after prolong
The very first time late；If current CT scan is the second time CT scan of enhanced ct scans, then the delay very first time refers to CT for the first time
The very first time is postponed after scanning.Postpone CT scan before the very first time laggard trade, it is thus achieved that the DICOM image of current CT scan, will
The DICOM image of current CT scan is shown to operator.
The DICOM image of the current CT scan of display is analyzed by operator, it is judged that set CT next time sweeps
The second time retouching required delay is the most accurate.Generally, if the picture quality of the DICOM image of current CT scan meets
When observing focus demand, required the second time postponed of the CT scan next time set by sign is accurate, it is not necessary to adjust next time
CT scan required the second time postponed.If the picture quality of the DICOM image of current CT scan cannot meet medical diagnosis
Demand, it is impossible to when meeting the demand observing focus, required the second time postponed of the CT scan next time set by sign is inaccurate
Really, need to adjust required the second time postponed of CT scan next time.
102: if required the second set of time postponed of the DICOM characterization image CT scan next time of current CT scan is forbidden
Time really, receive the adjustment signal of operator's input, adjust described second the 3rd time of acquisition time according to described adjustment signal.
When required second set of time postponed of DICOM characterization image CT scan next time of current CT scan is inaccurate,
Operator input adjustment signal, are adjusted, according to this adjustment signal, the second time postponed needed for CT scan next time,
The 3rd time that obtained is as the time of actual delay needed for CT scan next time.If it is understood that current CT scan is to increase
The first time CT scan of strong scanning, then the 3rd time obtained after adjusting for the second time is that second time CT scan is actually required
Time delay；If current CT scan is the second time CT scan of enhanced ct scans, then after the second time being adjusted gained the 3rd time
Between be third time CT scan actually required time delay.
During current CT scan, it is possible to obtain several DICOM images according to the sequencing of time.Operator press
According to the CT value of several DICOM images of sequential observation that DICOM image obtains, according to the change of the CT value of several DICOM images
Change and determine whether that the second time to postponing needed for CT scan next time is adjusted.
If during whole current CT scan, the CT value of all DICOM images constantly increases, then it represents that to current CT scan
The very first time of the required delay pre-set is earlier, then give the second of the required delay that CT scan pre-sets next time
Time is inaccurate, then the adjustment signal of operator's input is used for extending this second time, the ratio of the 3rd time after i.e. adjusting the
Two times are big.If during whole current CT scan, the CT value first increases and then decreases of all DICOM images, then it represents that give and work as
The very first time of the required delay that front CT scan pre-sets is accurate, it is not necessary to adjust this second time.If whole current CT scan
During, the CT value of all DICOM images constantly reduces, then it represents that second eaten required for pre-setting to current CT scan
Time compares rearward, then give CT scan next time pre-set required for the second time of eating inaccurate, then operator are defeated
Adjustment signal for this second time selected, the 3rd time after i.e. adjusting is less than the second time.
Illustrate: if under original state, the time delay of the first time CT scan of the enhanced ct scans that operator are arranged
Being 10s, the time delay of CT scan is 20s for the second time, and the time delay of CT scan is 40s for the third time.If current CT scan is
CT scan for the first time, the picture quality of the DICOM image of current CT scan cannot meet the demand of medical diagnosis, several DICOM
When the CT value of image constantly increases, then arrange inaccurate the time delay of second time CT scan, need to extend second time CT scan
Time delay, such as: be 25s according to adjusting the 3rd time of gained after signal adjusts, i.e. for the first time after CT scan, postpone
Second time CT scan is carried out again after 25s.
Illustrate again: if under original state, during the delay of first time CT scan of the enhanced ct scans that operator are arranged
Between be 10s, the time delay of CT scan is 20s for the second time, and the time delay of CT scan is 40s for the third time.If current CT scan
For second time CT scan, the picture quality of the DICOM image of current CT scan cannot meet the demand of medical diagnosis, several
When the CT value of DICOM image constantly reduces, then arrange inaccurate the time delay of third time CT scan, need to shorten third time CT
The time delay of scanning, such as: after adjusting the 3rd time 35s of gained after signal adjusts, i.e. second time CT scan, postpone
Third time CT scan is carried out again after 35s.
When implementing, receive the adjustment signal of operator's input, when adjusting described second according to described adjustment signal
Between obtain the 3rd time, at least three kinds of possible implementations, are described in detail separately below.
The first possible implementation, the adjustment signal of described reception operator input, according to described adjustment signal
Adjust described second the time obtain the 3rd time include:
Receive operator's drag operation to identifying the slide block of CT scan next time on delay time axle；
Detect the scale value that described slide block is residing on described delay time axle；
Described 3rd time is determined according to described scale value.
Scale value on delay time axle can represent delay time, and delay time axle is provided with slide block, residing for slide block
The CT scan that identified by this slide block of scale value needed for time of time delay.As in figure 2 it is shown, this delay time axle can be identified for that increasing
Each CT scan required time postponed of strong scanning.Having three slide blocks on this coordinate axes, slide block A identifies CT scan for the first time,
Slide block B mark second time CT scan, and slide block C mark third time CT scan, each slide block quarter on this delay time axle
Angle value is the CT scan required time postponed that this slide block is identified.I.e., if desired adjust the required delay of CT scan next time
The second time time, operator can pull manipulation to the slide block identifying CT scan next time, until residing for this slide block
Till scale value is the time of required delay.
Illustrate: if current CT scan is first time CT scan, need the time postponed needed for second time CT scan
When being adjusted, receiving operator's drag operation to the slide block B of mark second time CT scan, if detecting, operator will
It is at 25s that slide block B is drawn to delay time axle high scale value, then after adjusting, the 3rd time of gained is 25s.
The implementation that the second is possible, the adjustment signal of described reception operator input, according to described adjustment signal
Adjust described second the time obtain the 3rd time include:
Receive operator's numeral of input in the input frame of once CT scan in mark；
Described numeral is utilized to replace described second time as the 3rd time.
Offer can adjust the inputting interface of the time delay of each CT scan of enhanced ct scans, on this inputting interface, often
Secondary CT scan corresponds to an input frame, and in this input frame, input numeral, can adjust the CT scan corresponding to this input frame
Required time delay.As it is shown on figure 3, CT scan corresponding input frame time delay, CT scan delay for the second time for the first time
A time corresponding input frame, for the third time CT scan corresponding input frame time delay.If desired second time CT scan is adjusted
Required time delay, then corresponding input frame inputs in this second time CT scan time delay the number of required time delay
Word.
Illustrate: if current CT scan is first time CT scan, need the time postponed needed for second time CT scan
When being adjusted, if initial time input frame corresponding to second time CT scan time delay in numeral be 20s, then the pre-set
The delay time of rescan is 20s.If receiving operator's number in input frame corresponding to second time delayed sweep time
Word is 25s, then the 3rd time after adjusting is 25s.
Need exist for explanation, operator's numeral of input in the input frame of once CT scan in mark is permissible
It is to input from numeric keypad, the drop-down menu of the input frame of click CT scan next time can be used to select input, also may be used
To use other input modes, repeat the most one by one.
The third possible implementation, the adjustment signal of described reception operator input, according to described adjustment signal
Adjust described second the time obtain the 3rd time include:
Receive operator's clicking operation to being immediately performed the button of CT scan next time；
Determine that described 3rd time is 0 according to described clicking operation.
On the inputting interface of the time delay of each CT scan adjusting enhanced ct scans, it is also possible to arrange one " immediately
Perform CT scan next time " button, as shown in Figure 4.Generally, after current CT scan terminates, postpone CT next time and sweep
Retouching the second required time, scanning device carries out CT scan next time automatically.If operator are obtained for current CT scan
DICOM image be analyzed, it is believed that without postponing for the second time, and should be immediately performed next time CT scan time, then operate
Personnel click on this button " being immediately performed CT scan next time ", and now, scanning device then will not postpone for the second time, but vertical
I.e. perform CT scan next time.It not the most the most only to need the second time of delay CT scan next time, but receive operator's point
Hit the operation of " being immediately performed CT scan next time " case, force to be immediately performed CT scan next time.
Illustrate: if current CT scan is first time CT scan, the then operator DICOM to current CT scan gained
After image is analyzed, it is believed that without postponing for the second time, it should carry out second time CT scan immediately, then operator can point
Hit the button of " being immediately performed CT scan next time ", now, be immediately performed second time CT scan.It is to say, in examples detailed above
In, be adjusted obtaining for the 3rd time to the second time, and the 3rd time obtained be 0, the i.e. the 3rd time be 0 sign immediately
Perform second time CT scan, it is not necessary to postpone.
Certainly, the present invention is realizing receiving the adjustment signal of operator's input, adjusts described according to described adjustment signal
Second time obtained for the 3rd time, it is also possible to uses additive method to realize, repeats no more here.
103: after current CT scan, the 3rd time described in time delay carries out CT scan next time.
According to the adjustment signal of operator's input, the second time was adjusted, it is thus achieved that after the 3rd time after adjustment,
After current CT scan, time delay the 3rd time carries out CT scan next time.
In one example, described method also includes:
If required the second set of time postponed of the DICOM characterization image CT scan next time of current CT scan is accurate,
Second time described in time delay carries out CT scan next time.
If required the second set of time postponed of the DICOM characterization image CT scan next time of current CT scan gained is accurate
True, then need not the second time was adjusted, second time that postponed after current CT scan carries out CT scan next time.
