Specific embodiment
In order to provide the implementation for the CT images for enhancing scanning for obtaining high quality, the embodiment of the invention provides one kind
The method of adjustment and device for enhancing the delayed sweep time of scanning, below in conjunction with Figure of description to the preferred embodiment of the present invention
It is illustrated.
Fig. 1 is the method for adjustment flow chart of the delayed sweep time of enhancing scanning provided in an embodiment of the present invention, comprising:
101: delay carries out current CT scan at the first time, shows DICOM (the Digital Imaging of current CT scan
And Communications in Medicine, digital imaging and communications in medicine) image.
Enhancing scanning generally includes multiple CT scan, after the first time postponed needed for current CT scan determines, delay the
One time carried out current CT scan.The first time postponed needed for current CT scan can be operator to current CT scan
The delay time of initial setting up, i.e., the delay time not being adjusted；It is also possible to operator to adjust according to actual needs
Delay time afterwards.It is delay time needed for the current CT scan having determined at the first time.
If current CT scan is the first time CT scan of enhancing scanning, postpone to prolong after referring to intravenous injection at the first time
Late at the first time；If current CT scan is second of CT scan of enhancing scanning, postpone to refer to first time CT at the first time
Postpone at the first time after scanning.CT scan before the delay first time laggard trade, obtains the DICOM image of current CT scan, will
The DICOM image of current CT scan is shown to operator.
Operator analyzes the DICOM image of the current CT scan of display, judges that set CT next time is swept
Whether the second time postponed needed for retouching is accurate.Under normal circumstances, if the picture quality of the DICOM image of current CT scan meets
When observing lesion demand, the second time for characterizing delay needed for set CT scan next time is accurate, next time without adjustment
The second time postponed needed for CT scan.If the picture quality of the DICOM image of current CT scan is unable to satisfy medical diagnosis
When being unable to satisfy the demand of observation lesion, it is inaccurate to characterize the second time postponed needed for set CT scan next time for demand
Really, the second time postponed needed for adjusting CT scan next time is needed.
102: if required the second time setting postponed of CT scan next time of the DICOM characterization image of current CT scan is inaccurate
When true, the adjustment signal of operator's input is received, the acquisition third time the second time is adjusted according to the adjustment signal.
When inaccuracy is arranged in second time of the DICOM characterization image of the current CT scan required delay of CT scan next time,
Operator inputs adjustment signal, is adjusted according to second time of the adjustment signal to delay needed for CT scan next time,
Obtain time of the third time as actual delay needed for CT scan next time.It is understood that if current CT scan is to increase
The first time CT scan scanned by force is then that second of CT scan is actually required to the third time obtained after the adjustment of the second time
Delay time；If current CT scan is second of CT scan of enhancing scanning, after adjusting to the second time when resulting third
Between be third time CT scan actually required delay time.
During current CT scan, several DICOM images can be obtained according to the sequencing of time.Operator presses
According to the CT value of several DICOM images of the sequential observation of DICOM image acquisition, according to the change of the CT value of several DICOM images
Change determines whether to be adjusted the second time of delay needed for CT scan next time.
If the CT value of all DICOM images constantly increases, then it represents that gives current CT scan during entire current CT scan
The first time postponed needed for pre-set is earlier, then second postponed needed for pre-set to CT scan next time
Time inaccuracy, then the adjustment signal of operator's input is for extending second time, i.e., the third time adjusted is than the
Two times are big.If during entire current CT scan, the CT value first increases and then decreases of all DICOM images, then it represents that working as
The first time postponed needed for preceding CT scan is pre-set is accurate, without adjusting second time.If entire current CT scan
In the process, the CT value of all DICOM images constantly reduces, then it represents that second eaten required for pre-set to current CT scan
Time compares rearward, then the second time inaccuracy eaten required for pre-set to CT scan next time, then operator is defeated
Adjustment signal be used for selected second time, i.e., the third time adjusted is smaller than the second time.
If for example: under original state, the delay time of the first time CT scan of the enhancing scanning of operator's setting
It is 10s, the delay time of second of CT scan is 20s, and the delay time of third time CT scan is 40s.If current CT scan is
The picture quality of first time CT scan, the DICOM image of current CT scan is unable to satisfy the demand of medical diagnosis, several DICOM
When the CT value of image constantly increases, then inaccuracy is arranged in the delay time of second of CT scan, needs to extend second of CT scan
Delay time, such as: the resulting third time is 25s after being adjusted according to adjustment signal, i.e., after first time CT scan, delay
Second of CT scan is carried out after 25s again.
Again for example: if under original state, operator setting enhancing scanning first time CT scan delay when
Between be 10s, the delay time of second of CT scan is 20s, and the delay time of third time CT scan is 40s.If current CT scan
Picture quality for second of CT scan, the DICOM image of current CT scan is unable to satisfy the demand of medical diagnosis, several
When the CT value of DICOM image constantly reduces, then inaccuracy is arranged in the delay time of third time CT scan, needs to shorten third time CT
The delay time of scanning, such as: resulting third time 35s after being adjusted according to adjustment signal, i.e. after second of CT scan, delay
Third time CT scan is carried out after 35s again.
When specific implementation, the adjustment signal of operator's input is received, when according to adjustment signal adjustment described second
Between obtain the third time, at least there are three types of possible implementation, be described in detail separately below.
The first possible implementation, the adjustment signal for receiving operator's input, according to the adjustment signal
Adjusting second time obtains the third time and includes:
Operator is received to the drag operation for identifying the sliding block of CT scan next time on delay time axis；
Detect sliding block scale value locating on the delay time axis；
The third time is determined according to the scale value.
Scale value on delay time axis can indicate delay time, be provided with sliding block on delay time axis, locating for sliding block
The CT scan that is identified for the sliding block of scale value needed for time for being delayed.As shown in Fig. 2, the delay time axis can be identified for that increasing
The time postponed needed for each CT scan scanned by force.There are three sliding block in the reference axis, sliding block A identifies first time CT scan,
Slide block B identifies second of CT scan and sliding block C identifies third time CT scan, quarter of each sliding block on the delay time axis
Angle value is the time postponed needed for the CT scan that the sliding block is identified.That is, if desired adjusting delay needed for CT scan next time
The second time when, operator can carry out dragging manipulation to the sliding block of mark CT scan next time, until locating for the sliding block
Until scale value is the time of required delay.
For example: if current CT scan is first time CT scan, needs the time to delay needed for second of CT scan
When being adjusted, operator is received to the drag operation of the slide block B of second of CT scan of mark, if detecting, operator will
It is at 25s that slide block B, which is drawn to delay time axis high scale value, then the resulting third time is 25s after adjusting.
Second of possible implementation, the adjustment signal for receiving operator's input, according to the adjustment signal
Adjusting second time obtains the third time and includes:
Receive the number that operator inputs in the mark next time input frame of CT scan；
Replace second time as the third time using the number.
The input interface that can adjust the delay time of each CT scan of enhancing scanning is provided, on the input interface, often
Secondary CT scan corresponds to an input frame, and number, CT scan corresponding to the adjustable input frame are inputted in the input frame
Required delay time.As shown in figure 3, CT scan delay time first time corresponds to an input frame, second of CT scan delay
Time corresponds to an input frame, a third time CT scan delay time corresponding input frame.If desired second of CT scan is adjusted
Required delay time then inputs the number of required delay time in second of CT scan delay time corresponding input frame
Word.
For example: if current CT scan is first time CT scan, needs the time to delay needed for second of CT scan
When being adjusted, if number is 20s in second of CT scan delay time corresponding input frame when initial, pre-set the
The delay time of rescan is 20s.If receiving operator's number in second of delayed sweep time corresponding input frame
Word is 25s, then the third time adjusted is 25s.
It, can be with what needs to be explained here is that the number that operator inputs in the input frame of CT scan in mark next time
It is to be inputted from numeric keypad, the drop-down menu that the input frame of CT scan next time can be clicked using mouse selects input, may be used also
To use other input modes, no longer repeat one by one here.
The third possible implementation, the adjustment signal for receiving operator's input, according to the adjustment signal
Adjusting second time obtains the third time and includes:
Operator is received to the clicking operation for being immediately performed the key of CT scan next time；
Determine that the third time is 0 according to the clicking operation.
On the input interface of the delay time of each CT scan of adjustment enhancing scanning, one can also be arranged " immediately
Execute CT scan next time " key, as shown in Figure 4.Under normal circumstances, after current CT scan, CT is swept next time for delay
The second required time is retouched, scanning device carries out CT scan next time automatically.If operator is obtained for current CT scan
DICOM image analyzed, it is believed that without postponing for the second time, and when should be immediately performed CT scan next time, then operate
Personnel click the key for being somebody's turn to do " being immediately performed CT scan next time ", at this point, scanning device will not then postpone for the second time, but it is vertical
Execute CT scan next time.I.e. instead of the second time of delay does not only need CT scan next time automatically, receives operator's point
The operation of " being immediately performed CT scan next time " case is hit, pressure is immediately performed CT scan next time.
For example: if current CT scan is first time CT scan, operator DICOM resulting to current CT scan
After image is analyzed, it is believed that without postponing for the second time, it should carry out second of CT scan immediately, then operator can point
The key of " being immediately performed CT scan next time " is hit, at this point, being immediately performed second of CT scan.That is, in examples detailed above
In, the second time was adjusted and obtains the third time, and the third time obtained is 0, i.e. the third time characterizes immediately for 0
Second of CT scan is executed, without delay.
Certainly, the present invention is realizing the adjustment signal for receiving operator's input, according to adjustment signal adjustment
Second time obtained the third time, can also realize which is not described herein again using other methods.
103: the third time that is delayed after current CT scan carries out CT scan next time.
According to the adjustment signal that operator inputs, the second time was adjusted, after obtaining the third time adjusted,
The delay third time carries out CT scan next time after current CT scan.
In one example, the method also includes:
If the second time setting of the DICOM characterization image of the current CT scan required delay of CT scan next time is accurate,
Be delayed the second time progress CT scan next time.
If required the second time setting postponed of CT scan next time of the resulting DICOM characterization image of current CT scan is quasi-
True, then it does not need to be adjusted for the second time, postpones the second time progress CT scan next time after current CT scan.
