The dose of radiation that subject is subject to.
Referring to FIG. 2, for a kind of flow chart of Scan orientation method shown in one exemplary embodiment of the application, this method
CT master stations shown in FIG. 1 are can be applied to, are included the following steps：
Step 201：Receive the first start bit for being performed the when of originating location action with scanning bed corresponding positioning key and sending
It sets, the origination action is adjusted the scanning bed position by user, so that initial position to be scanned reaches instruction
It is executed when position.
In the present embodiment, operator can first open the positioning lamp being arranged in CT racks or scanning room's wall, and lead to
It crosses for motion scan bed into bed key or moves back a key scanning bed position is adjusted, make the start bit that subject is to be scanned
The indicating positions for reaching the positioning lamp is set, wherein into bed key or moving back a key and can be arranged on scanning bed, can also be arranged remote
From scanning bed position, but with scanning bed connection.Certainly, indicating positions can also be by CT equipment or associated with CT equipment
Other positioning devices determine, subsequent step is described for determining indicating positions by positioning lamp in this application.
When the initial position to be scanned reaches the indicating positions of the positioning lamp, operator can pair with it is scanning bed corresponding

After body is performed the starting location action, scanning bed current location can be obtained, and is sent to CT master stations；Alternatively, this is fixed
Position key can send starting positioning instruction, by CT master after detecting and itself being performed the starting location action to CT master stations
Control platform obtains scanning bed current location.
For the ease of scanning the record of bed position, the concept of bed code can be introduced.Referring to FIG. 3, being a kind of scanning bed
Schematic diagram.As shown in figure 3, A points and B points are scanning bed can reach 2 extreme position, i.e. the distance between A points and B points are
The movable distance of the scanning bed head of a bed.Assuming that the movable distance is 2 meters, then the bed code of A points can be set to 0 meter, and by B
The bed code of point is set as 2 meters.It is further assumed that the distance between C points and A points are 0.52 meter, the distance between D points and A points are
1.00 meters, then the bed code of C points is 0.52 meter, and the bed code of D points is 1.00 meters；And so on.
Step 202：It receives the positioning key and is performed the first end position for terminating to be sent when location action, the end
Action is adjusted the scanning bed position by user, so that end position to be scanned executes when reaching indicating positions.
In the present embodiment, operator, can be again by upper after being positioned to above-mentioned initial position to be scanned
It states into bed key or moves back a key scanning bed position is adjusted, it is above-mentioned fixed that the end position for keeping above-mentioned subject to be scanned reaches
The indicating positions of position lamp.When the end position to be scanned reaches the indicating positions of the positioning lamp, operator can be to above-mentioned
Positioning key, which executes, terminates location action, such as：Press the positioning key again or double-click the positioning key etc..
The positioning key can send scanning bed current location after detecting that itself being performed this terminates location action

It should be noted that in practical applications, positioning key can be divided into starting positioning key and terminate positioning key.Operation
Person can execute starting positioning key starting location action, and originating positioning key can then detect that itself being performed starting determines
First start bit is sent when the action of position to CT master stations to set.On the other hand, operator can terminate to determine to terminating positioning key execution
Position action, and terminate positioning key then can detect itself be performed terminate location action when to CT master stations send the first knot
Beam position.
In an alternative embodiment, if operator when the first start bit of prelocalization to setting or the first end position
It is dissatisfied, or accidentally touching above-mentioned positioning key causes positioning to malfunction, and can be executed to the positioning key and cancel location action, such as：It is long
By the positioning key etc..The positioning key detect itself be performed cancel location action when, can to CT master stations send cancel
Positioning instruction.CT master stations can set the first start bit being currently received or when receiving the cancellation positioning instruction
One end position is deleted.
In another optional embodiment, if operator when the first start bit of prelocalization to setting or the first stop bits
Set it is dissatisfied, or accidentally touch the positioning key cause positioning malfunction, can also to above-mentioned positioning lamp execute closing motion.The positioning lamp
When detecting that itself is performed closing motion, it can also be sent to CT master stations and cancel positioning instruction.CT master stations are receiving
When to the cancellation positioning instruction, the first start bit being currently received can be set or the first end position is deleted.
Step 203：Based on the first start bit set with the first end position, determine scanning direction and first scanning length
Degree.
In the present embodiment, CT master stations get above-mentioned first start bit set with after the first end position, can be with base
In the first start bit set with the first end position, determine scanning direction and the first sweep length.Specifically, CT master stations can be with
It calculates the corresponding bed code of first end position and the first start bit sets the difference of corresponding bed code, and according to the positive and negative of the difference
Determine scanning direction.
Such as：Assuming that the scanning bed bed code in the closer position of distance CT racks is smaller, and farther out in distance CT racks
The bed code of position is larger, then when the difference is positive number, it may be determined that scanning direction is (i.e. scanning bed to CT racks into bed scanning
It is mobile), and when the difference is negative, it may be determined that scanning direction is to move back bed to scan (i.e. scanning bed separate CT machine frame movements).
Meanwhile the absolute value of the difference can be determined as the first sweep length by CT master stations.As an example it is assumed that the first start bit
It is 0.40 meter to set corresponding bed code, and the corresponding bed code of first end position is 0.95 meter, and the position that distance CT racks are closer
Bed code it is smaller, then can determine scanning direction be into bed scan, and the first sweep length be 0.55 meter.
In practical applications, if sweep length is not sweep length (being usually the width of the detector in CT racks)
Integral multiple can round up to sweep length then during control is scanned subject, to ensure to obtain
Subject CT images integrality.
In order to simplify scanning process, scan efficiency is improved, in an alternative embodiment, referring to FIG. 4, may be used
Following steps determine the first sweep length：
Step 2031：Whether judge that first end position and the first start bit the distance between are set is preset
The integral multiple of sweep length.
Step 2032：If the distance is not the integral multiple of the sweep length, the distance is taken upwards
It is whole.
Step 2033：Distance after rounding up is determined as the first sweep length, and is set based on the first start bit
First end position is adjusted with the first determining sweep length.
In the present embodiment, CT master stations can first judge between above-mentioned first end position and first start bit are set away from
From whether be preset sweep length integral multiple, wherein sweep length can pre-set by operator.If it is, CT master
Control platform, which can directly the distance between set first end position and first start bit, is determined as the first sweep length.If no
It is that then CT master stations, which the distance between can set first end position and first start bit, rounds up, and will be to
Distance after upper rounding is determined as the first sweep length.
As an example it is assumed that preset sweep length is 0.05 meter, it is 0.42 meter which, which sets corresponding bed code,
The corresponding bed code of first end position is 0.60 meter, since 0.60 meter -0.42 meter=0.18 meter be not 0.05 meter of integer
Times, therefore CT master stations can round up to 0.18 meter, i.e., be determined as the first sweep length by 0.20 meter.
Correspondingly, CT master stations are by the distance after rounding up after being determined as the first sweep length, can according to this
One sweep length and first start bit, which are set, is adjusted first end position.Continue with above-mentioned to be exemplified as example, by 0.20
After rice is determined as the first sweep length, it is 0.42 meter to set corresponding bed code due to the first start bit, and CT master stations can be with
The corresponding bed code of first end position is adjusted to 0.42 meter+0.20 meter=0.62 meter.
Step 204：It is set based on the scanning direction, first start bit, the first end position and the first sweep length, control
Subject is scanned.
In the present embodiment, after determining scanning direction and the first sweep length, CT master stations can control CT racks
It is set according to the scanning direction, first start bit, the first end position and the first sweep length these sweep parameters, is examined to above-mentioned
Body is scanned.
It should be noted that operator can select to carry out CT scan or plain film scanning to the subject.If operator
Selection carries out CT scan to the subject, then CT master stations can control CT racks according to these sweep parameters, to the subject
CT scan is carried out, to obtain the CT images of the subject.If operator's selection carries out plain film scanning, CT master to the subject
Control platform can control CT racks according to these sweep parameters, and plain film scanning is carried out to the subject, to obtain the flat of the subject
Picture.
As seen from the above-described embodiment, CT master stations can utilize the start bit of the scanning of positioning according to the operator received
Set and end position, it is automatic to calculate scanning direction and sweep length, with control CT racks according to initial position, end position, sweep
It retouches direction and sweep length these sweep parameters is scanned subject, without being estimated again by operator and by CT master controls
These sweep parameters of platform manual setting.In this manner, it is not necessarily to carry out plain film scanning to subject in advance, or to being examined
Body carries out multiple CT scan, and CT master stations can directly acquire accurate sweep parameter, so as to improve scan efficiency, simultaneously
The dose of radiation that subject is subject to can be reduced.
In an alternative embodiment, it is also based on the above method and multistage scanning is carried out to subject.Specifically,
Operator is executing end location action to above-mentioned positioning key, after so that the positioning key is sent the first end position to CT master stations,
Again by above-mentioned into bed key or a key can also be moved back scanning bed position is adjusted, make above-mentioned subject is next to wait sweeping
The initial position retouched reaches the indicating positions of above-mentioned positioning lamp.The finger of the positioning lamp is reached in next initial position to be scanned
When showing position, operator can execute starting location action to the positioning key again.
The positioning key can send scanning bed current location after detecting and itself being performed the starting location action
Give CT master stations.At this point, being set due to having preserved the first start bit received before in CT master stations, CT master stations can
The position to be preserved as the second initial position.
Similarly, operator is after positioning next initial position to be scanned, can be again by this into bed
Key moves back a key and is adjusted to scanning bed position, and the next end position to be scanned of the subject is made to reach above-mentioned positioning
The indicating positions of lamp.When next end position to be scanned reaches the indicating positions of the positioning lamp, operator can be again
The positioning key is executed and terminates location action.
The positioning key can send scanning bed current location after detecting that itself being performed this terminates location action
Give CT master stations.At this point, due to having preserved the first end position received before in CT master stations, CT master stations can
The position to be preserved as the second end position.
And so on, may be used such method make CT master stations determine multistage scan corresponding initial position and
End position is herein only described subsequent step by taking two sections of scanning as an example.
With reference to the description of above-mentioned steps 203 and 204, CT master stations are determining second initial position and the second end position
Afterwards, it can be based on second initial position and the second end position, determine the second sweep length.Subsequently, CT master stations can be controlled
CT racks processed set according to above-mentioned scanning direction, first start bit, the first end position and the first sweep length and this second
Beginning position, the second end position and the second sweep length these sweep parameters, which is scanned.
In practical applications, it since different Scanning Sections usually corresponds to the different zones on subject body, is applicable in
CT scan sequence also different from, therefore operator can be that different CT scan sequences is arranged in different Scanning Sections, i.e., on
It states first start bit and sets the first scanning sequence corresponding with the first end position, with above-mentioned second initial position and the second stop bits
It is different to set corresponding second scanning sequence.
On the other hand, for plain film scanning, the corresponding plain film of different Scanning Sections is also different, i.e., and above-mentioned first
Initial position and corresponding first plain film of the first end position, corresponding with above-mentioned second initial position and the second end position
Two plain films are different.
It can be seen that using such method, the multistage scanning to subject can be realized in single pass, is not only carried
High scan efficiency, can also reduce the dose of radiation that subject is subject to.For example, if necessary to utilize certain sufferer simultaneously
Chest CT image and abdominal CT images are diagnosed, then can be using the chest area of the sufferer as the first Scanning Section, abdomen part
Domain obtains the chest CT image and abdominal CT images of the sufferer simultaneously as the second Scanning Section, by single pass, without right
The sufferer carries out twice sweep, to respectively obtain the chest CT image and abdominal CT images of the sufferer.
