The example of the consistent apparatus and method of some aspects being described in detail in claims, of the invention.
CT perfusion scannings are a kind of common enhancing scan modes, in general, CT perfusion scannings can be divided into dynamic perfusion scanning
With static perfusion scanning, wherein, dynamic perfusion scanning refers to during perfusion scanning, it is scanning bed can along scanning bed length direction
To move back and forth, similar infanette swings back and forth, and the detector being also secured on scanning support is with scanning support around sweeping
Position rotation is retouched, in this way, the coverage of CT scan system can be increased i.e. along the sweep length on scanning bed length direction；And
Static perfusion scanning refers to during perfusion scanning, scanning bed static, does not move, the spy being only integrally fixed on scanning support
Device is surveyed to rotate around scanned position with scanning support, therefore under static perfusion scanning, bed length is scanned on the edge that scanning system is supported
Sweep length on direction is less than under dynamic perfusion scanning, and what scanning system was supported grows along the scanning on scanning bed length direction
Degree.
When carrying out CT perfusion scannings, often according to the position and sweep length to be scanned, manually select perfusion and sweep
Mode and sweep spacing period are retouched, not only the degree of automation is low, reduces work efficiency, and the same position of continuously scanning selected
Time interval, that is, sweep spacing period it is inaccurate, inevitably it is bigger than normal or less than normal.If the sweep spacing period is bigger than normal, perfusion is caused to be swept
The picture quality retouched does not reach requirement, fogging image；If the sweep spacing period is less than normal, cause continuously to scan same position
Number is too many, and the comparison dosage that patient absorbs is more, and patient body is caused centainly to injure.It is to solve the above problems, of the invention
A kind of CT perfusion scannings method is provided.
Fig. 1 is a kind of CT perfusion scannings method flow diagram shown in an exemplary embodiment of the invention, as shown in Figure 1, should
CT perfusion scanning methods comprise the following steps：
In a step 101, the sweep length at position to be scanned is obtained.
In a step 102, perfusion scanning is determined according to the sweep length at the position to be scanned and default sweep length
Mode.
In the present embodiment, the perfusion scanning mode includes static perfusion scanning and dynamic perfusion scanning, it can be determined that
Whether the sweep length at the position to be scanned is less than or equal to default sweep length, if so, using static perfusion scanning side
Formula is irrigated scanning, if it is not, being then irrigated scanning using dynamic perfusion scanning mode.
In the present embodiment, the default sweep length can be less than or equal to detector width.
In step 103, under identified perfusion scanning mode, the scanning times at the position to be scanned is set and are swept
Retouch interval period.
In the present embodiment, under static perfusion scanning mode, can be set according to the sweep length at the position to be scanned
Put the sweep spacing period.
Under dynamic perfusion scanning mode, it can be determined that the scanning room set according to the sweep length at the position to be scanned
Every period and the size for the optimum scanning interval period for scanning the position to be scanned.If according to the scanning at the position to be scanned
The sweep spacing period that length is set is less than or equal to the optimum scanning interval period, then when setting the optimum scanning interval
Section is the sweep spacing period of scanning system.It is if big according to the sweep spacing period that the sweep length at the position to be scanned is set
In the optimum scanning interval period, then prompt the user to choose whether to continue to treat scanned position and be irrigated scanning.Work as reception
Continue to treat scanned position to user when being irrigated the instruction of scanning, then the sweep length according to the position to be scanned is set
The sweep spacing period of setting is the sweep spacing period of scanning system.
At step 104, according to identified scanning times and sweep spacing period, the position to be scanned is filled
Note scanning.
Sweep length and default scanning of the CT perfusion scannings method provided by the invention according to the position to be scanned got
Length automatically selects perfusion scanning mode, and under identified perfusion scanning mode, automatic set scans above-mentioned portion to be scanned
The scanning times of position and sweep spacing period, according to identified scanning times and sweep spacing period, treat scanned position into
Row perfusion scanning avoids the sweep spacing period that user manually selects bigger than normal or less than normal, makes the same position of continuously scanning of setting
Time interval, that is, sweep spacing period it is more accurate, ensure CT perfusion scannings image clearly on the premise of, can try one's best
Reduce the number for continuously scanning same position, reduce the amount that patient absorbs contrast medium, and then reduce the injury to patient.
Fig. 2 is another CT perfusion scannings method figure shown in an exemplary embodiment of the invention, is comprised the following steps：
In step 201, the sweep length at position to be scanned is obtained.
In the present embodiment, user can be selected to be scanned by the button being previously provided in scanning system or touch-screen etc.
Sweep length on position and the position to be scanned, the sweep length are position to be scanned along the length on scanning bed length direction
Degree.
In other implementations, scanning system can sweeping according to image acquiring device automatic identification position to be scanned
Retouch length, image acquiring device can be video camera etc., and the present invention to this and is not limited, it is any can identify it is to be scanned
The device of the sweep length at position is all within protection scope of the present invention.
In step 202, judge whether the sweep length at position to be scanned is less than default sweep length.
In the present embodiment, the default sweep length refers to that scanning system can when using static perfusion scanning mode
The maximum scan length of support, i.e. detector width.The default sweep length is a critical value, can be used for distinguishing using quiet
State perfusion scanning mode still uses dynamic perfusion scanning mode.During due to using static perfusion scanning, in perfusion scanning process
Middle patient lain it is scanning bed will not move, simply detector with scanning support around scanned position rotate, and use dynamic fill
Note scanning when, during perfusion scanning patient lain it is scanning bed can carry patient carry out periodic reverse motion, so
The maximum scan length that system is supported under static perfusion scanning mode is less than the system under dynamic perfusion scanning mode and supports most
Expose thoroughly length.Therefore before scanning is irrigated, it is necessary first to be swept according to the sweep length at above-mentioned position to be scanned with default
The size for retouching length relatively determines perfusion scanning mode, when the sweep length at above-mentioned position to be scanned is less than or equal to above-mentioned preset
During sweep length, using static perfusion scanning mode, into following step 203；Conversely, when the sweep length at position to be scanned
More than default sweep length, then using dynamic perfusion scanning mode, into following step 205.
In step 203, under static perfusion scanning mode, sweep spacing is set according to the sweep length at position to be scanned
Period.
In the present embodiment, the sweep length at position to be scanned is compared in above-mentioned steps 202 less than or equal to default
During sweep length, then perfusion scanning mode is switched to static perfusion scanning by scanning system automatically.
In the present embodiment, the sweep spacing period refers to the time interval for continuously scanning same position, if the sweep spacing
Choosing period of time is bigger than normal, then the poor image quality of perfusion scanning shooting, causes fogging image, can not find out from image scanned
Whether position occurs lesion；If the sweep spacing choosing period of time is less than normal, excessive to scanned position scanning times, correspondingly, suffer from
The contrast medium that person absorbs is more, and contrast medium can cause patient centainly to injure, so when being irrigated scanning, selection is suitably swept
It is very crucial to retouch interval period.The prior art is usually that user manually selects scan round duration certainly, does not pass through accurate calculating,
Inevitably be present with selection scan round duration it is bigger than normal or less than normal the phenomenon that, perfusion scanning method provided by the invention can basis
The sweep length at the position to be scanned selected in step 201 sets corresponding sweep spacing period and scanning times automatically.
In step 204, under dynamic perfusion scanning mode, judge to be swept according to what the sweep length at position to be scanned was set
Retouch the size of optimum scanning interval period of the interval period with scanning position to be scanned.
In the present embodiment, the sweep length that position to be scanned is compared in above-mentioned steps 202 is more than default scanning length
When spending, then perfusion scanning mode is switched to dynamic perfusion scanning by scanning system automatically.
In the present embodiment, in order to not only can guarantee the picture quality of perfusion scanning, but also it can guarantee that patient tries one's best few absorption
Contrast medium, it is necessary to calculate a suitable sweep spacing period, and define the sweep spacing period for optimum scanning interval when
Section.When using dynamic perfusion scanning, for different sweep lengths, what scanning system was supported retouches interval period difference；And root
Principle is perfused according to dynamic, the corresponding optimum scanning interval period of scanning different parts is also different, so being swept into Mobile state perfusion
, it is necessary to which whether that prejudges that scanning system supported under the sweep length at position to be scanned retouches interval period and be less than and treat before retouching
The corresponding optimum scanning interval period of scanned position.
For example, it is assumed that need to check that the liver of patient whether there is lesion, selected sweep length is 150mm, when
When patient lies in scanning bed upper with the posture of head towards scanning support, then selected sweep length 150mm is along scanning bed length
The length of liver on direction.According to dynamic perfusion scanning principle, the corresponding optimum scanning interval period of scanning liver is 3s, i.e., every
Carry out single pass to the area to be scanned of liver 150mm every 3s, and if scanning system in sweep length by being supported during 150mm
The sweep spacing period for 4s, wait to sweep at this point, the sweep spacing period that scanning system is supported is unable to reach scanning liver 150mm
The optimum scanning interval period at position is retouched, if continuing perfusion scanning, the fogging image that is likely to result in, Wu Fashi
Do not go out whether institute's scanned position occurs lesion.
In step 205, the sweep spacing period that optimum scanning interval period is scanning system is set.
In the present embodiment, swept when the sweep spacing period set according to the sweep length at position to be scanned is less than or equal to
The optimum scanning interval period at position to be scanned is retouched, when the sweep spacing that optimum scanning interval period is scanning system can be set
Section.For example, it is assumed that needing to detect kidneys of patients with the presence or absence of lesion, selected sweep length is 100mm, is swept according to dynamic perfusion
Retouch principle, the corresponding optimum scanning interval period of scanning kidney is 2s, i.e., every 2s need to the area to be scanned of kidney 100mm into
Row single pass, and if scanning system in sweep length is 1s by the sweep spacing period supported during 100mm, at this point,
Scanning system get position to be scanned for kidney when, can be automatically using the optimum scanning interval period 2s for scanning kidney as sweeping
Retouch the sweep spacing period of system.
In step 206, prompt the user to choose whether to continue to treat scanned position and be irrigated scanning.
In the present embodiment, it is optimal more than described when the sweep spacing period set according to the sweep length at position to be scanned
During the sweep spacing period, scanning system is unable to reach the corresponding optimum scanning interval period in position to be scanned at this time, identical
It is limited to the number of scanned position scanning in sweep time, the corresponding scanning times of optimum scanning interval period are unable to reach, it can
It can make the fogging image that perfusion scanning obtains, None- identified scanned position whether there is lesion, still, if scanning system
The sweep spacing period supported differs very little with optimum scanning interval period, and possible user also may proceed to be irrigated scanning,
Therefore, scanning system answers automatic spring dialog box to prompt the user to choose whether to continue to treat scanned position and be irrigated scanning.
In other implementations, scanning system can also be by sending the modes such as alarm, bright light or intelligent sound
It prompts the user to choose whether to continue to treat scanned position and is irrigated scanning, certainly, the present invention is to this and is not limited, any
It can play the role of the embodiment of prompting user all within protection scope of the present invention.
In step 207, it is scanning system to set the sweep spacing period set according to the sweep length at position to be scanned
The sweep spacing period.
When scanning system receive user continue to treat scanned position be irrigated the instruction of scanning when, then root can be set
The sweep spacing period set according to the sweep length at position to be scanned is the sweep spacing period of scanning system；When scanning system connects
Receive the instruction for not going on scanning or any instruction is not received by preset duration that user issues, scanning system
System can automatically exit from scanning imaging system.
In a step 208, according to identified scanning times and sweep spacing period, treat scanned position and be irrigated and sweep
It retouches.
In the present embodiment, be that description is easy, by static perfusion scanning and dynamic perfusion scanning it is general be known as filling
Note scanning can distinguish static perfusion scanning and dynamic perfusion scanning in practical operation by actual.
