Heart (Fh) when setting region-of-interest (ROI), the scanning of three-dimensional ultrasonic wave is executed in the three-dimensional space comprising fetus.
Fig. 3 is the figure for illustrating the scanning of three-dimensional ultrasonic wave.As shown in figure 3, for example being formed using the direction r as wave beam
The ultrasonic beam (send wave beam and receive wave beam) in direction (depth direction),The direction electron scanning ultrasonic beam and formed
Scanning surface S.It is, the wave beam address (beam address) for receiving wave beam is made to existIn scanning surface while variation on direction
Multiple row data corresponding with multiple wave beam addresses are formed in S.It is made of and scanning surface S multiple row data in scanning surface S
Corresponding frame data.
In turn, make scanning surface S while being moved on the direction θ, that is, the position that makes scanning surface S and angle (
Can be position or angle) ultrasonic beam is scanned in scanning surface S while changing on the direction θ.As a result, in three-dimensional space
Ultrasonic beam is three-dimensionally scanned, for example, concrete example as shown in Figure 3 is such, is formed in the frame number of the multiple frames arranged on the direction θ
According to.
The diagnostic ultrasound equipment of Fig. 1 is three-dimensionally scanned in the three-dimensional space comprising diagnosing object, that is, fetus heart
The frame data of multiple frames obtained by ultrasonic beam carry out reconstruction processing, and the three of the solid shape for mirroring the heart of fetus are consequently formed
Tie up image.It is carried out in advance before reconstruction processing, that is, before the reconstruction scanning of the frame data needed for collecting reconstruction processing
Scanning.
<prescan>
Fig. 4 is the figure for illustrating prescan.Prescan is carried out before rebuilding scanning.(A) of Fig. 4 indicates prescan
Concrete example, (B) of Fig. 4 indicate to rebuild the concrete example of scanning.
For example, concrete example as shown in Figure 4 is such, it is respectively formed in prescan and reconstruction scanning using the direction r as wave beam
The ultrasonic beam in direction (depth direction), and electron scanning Ultrasound beamforming scanning surface S.In turn, make scanning surface S in the side θ
Ultrasonic beam is scanned in scanning surface S while electronically or mechanically property is mobile upwards.It is sequentially formed on the direction θ and arranges as a result,
Multiple frames frame data.But the scanning range and scanning density (scanning speed) of prescan and reconstruction scanning on the direction θ
It is different from each other.
Prescan purpose is to confirm position and the size of the heart (Fh) of the fetus in three-dimensional space, therefore, according to this
Purpose determines scanning range and scanning density (scanning speed).For example, in prescan, to be wider than weight on angle, θ direction
The range for building scanning is scanned scanning surface S and with the scanning density (faster scanning speed) lower than reconstruction scanning to scanning
Face S is scanned.Also, such as with the position (side θ of the representative scanning surface S (referring to Fig. 2) for the setting for carrying out region-of-interest
To angle) centered on to be scanned than wider range (angular range in the direction θ) to scanning surface S.In addition it is also possible to
Scanning surface S is scanned with the maximum scanning range that can pass through 10 scanning of probe on angle, θ direction.
On the other hand, in limited the sweeping according to the position of the heart (Fh) of the fetus confirmed in prescan and size setting
It retouches to execute in range and rebuilds scanning.For example, the concrete example as shown in (B) of Fig. 4, the heart comprising fetus as far as possible
Scanning surface S is scanned on angle, θ direction in small range.In addition, the concrete example for rebuilding scanning is described in further detail later.
It is obtained out of three-dimensional space based on the frame data of the multiple frames obtained by prescan, that is, based on prescan is passed through
The three-dimensional data obtained determines to rebuild the scanning range of scanning.
Fig. 5 is the figure for indicating the concrete example of the three-dimensional data obtained by prescan.For example, in the heart comprising fetus
(Fh) prescan (referring to Fig. 4) is carried out in three-dimensional space, is stood while changing wave beam address on the direction φ and the direction θ
(referring to Fig. 3) when scanning to body ultrasonic beam, multiple line numbers corresponding with multiple wave beam addresses are formed in transmitting-receiving process portion 12
According to.In turn, in frame forming portion 20, by multiple row data in the scanning surface that is formed by the direction r and the direction φ constitute with should
The corresponding frame data of scanning surface.
Each row data are made of the multiple data arranged on the direction r, by by each row data configuration with the row data
The corresponding position in wave beam address, that is, by the way that multiple row data configurations are shown in fig. 5 to obtain in r φ θ coordinate system
Three-dimensional data.In concrete example shown in Fig. 5, each wave beam address and the coordinate value in the two-dimensional coordinate system in the direction φ and the direction θ
It is corresponding.
For example, being stored in data store 22 for three-dimensional data shown in fig. 5 as the scanning result of prescan.For example,
The frame data of the multiple frames arranged on the direction θ are sequentially stored in data store 22 according to each frame.Also, based on by pre-
The position of the heart (Fh) for the three-dimensional data confirmation fetus that scanning obtains and size and the scanning range for determining to rebuild scanning.Also
It is that data for projection forming portion 34 forms projected image, scanning range configuration part 36 based on the three-dimensional data obtained by prescan
It determines to rebuild the scanning range scanned based on projected image.
Fig. 6 is the figure for indicating the concrete example of projected image and scanning range.Data for projection forming portion 34 is based on being used as and sweep in advance
The scanning result retouched and be stored in the three-dimensional data (Fig. 5) in data store 22 and form projected image.For example, as shown in fig. 6,
The projected image for having projected the heart (Fh) of fetus is formed on the face comprising the direction φ and the direction θ.
Data for projection forming portion 34 is according to multiple row data of the composition three-dimensional data obtained by prescan, for each row
Data obtain data for projection respectively, form projected image hereby based on multiple data for projection corresponding with multiple row data.Projection
Data forming portion 34 is for example added up (addition process) to the multiple data for constituting each row data, using its aggregate-value as the row
The data for projection of data.In addition, data for projection forming portion 34 can also for example be selected from the multiple data for constituting each row data
Minimum data corresponding with the smallest echo strength as the row data data for projection.
When the chambers of the heart in the heart (Fh) that three-dimensional data expert data pass through fetus, in the row data include and the chambers of the heart
Corresponding data.Due to being mainly blood flow, the reflection of the ultrasonic wave compared with the tissues such as cardiac muscle in the chambers of the heart in the chambers of the heart
It is weaker.It is, the echo strength compared with the other parts such as cardiac muscle in the chambers of the heart is smaller.
Therefore, when the chambers of the heart in the heart (Fh) that each row data pass through fetus, due to echo strength corresponding with the chambers of the heart
It is smaller, therefore data for projection obtained by the accumulative multiple data for constituting the row data is also smaller.In addition, from constituting each line number
According to multiple data in corresponding with the smallest echo strength minimum data of selection as data for projection in the case where, also at this
When row data pass through the chambers of the heart in heart of fetus Fh, the data for selecting echo strength corresponding with the chambers of the heart minimum, if the row data
Not by the chambers of the heart, then the data of stronger echo strength corresponding with tissues such as cardiac muscles are selected.
Therefore, the chambers of the heart part being made of in the heart (Fh) of fetus the lesser data group of echo strength (pixel group) is formed
And the projected image of the part other than the heart of fetus is made of the stronger data group of echo strength (pixel group).
Furthermore it is preferred that implementing in projected image by such as area in the lesser image section of echo strength (pixel group)
Image section less than a reference value such as is considered as the noise of non-fetal heart Fh and removes at the processing.It can be used when removing noise known
Various processing it is any.
Scanning range configuration part 36 is based on from the projected image decision reconstruction processing that data for projection forming portion 34 obtains
The scanning range of reconstruction scanning in reconstruction processing.The heart (Fh) of fetus is extracted in projected image in scanning range configuration part 36
Image-region, based on the image-region determine scanning range.For example, by using identification pixel corresponding with the chambers of the heart with remove
The binary conversion treatment of the threshold value of pixel other than this determines the image-region of the heart (Fh) of fetus in projected image.
When the image-region of heart (Fh) of fetus has been determined, scanning range configuration part 36 sets the heart by fetus
(Fh) the scounting line L at the center (for example, area focus point or near it) of image-region.For example, as shown in fig. 6, setting is flat
Row is in the scounting line L in the direction θ.
Then, the boundary of the heart (Fh) of fetus is searched in scanning range configuration part 36 on scounting line L.For example, from fetus
The center (for example, area focus point or near it) of image-region of heart (Fh) start to search for the direction θ on scounting line L
The respective boundary of side and the other side.For example, search from the corresponding pixel variation of heart (chambers of the heart) with fetus is and cardiac muscle
Etc. the location of pixels of corresponding pixel.The side boundary and another side of the heart (Fh) of fetus are determined on scounting line L as a result,
The two boundaries of boundary.In the concrete example of Fig. 6, the position of θ 1 and the position of θ 2 are two boundaries.
Scanning range configuration part 36 according to by scounting line determine two boundaries and determination fetus heart
(Fh) drop shadow spread come determine rebuild scanning scanning range.For example, in the concrete example of Fig. 6, according to from the position of θ 1 to θ
The drop shadow spread of the heart (Fh) of 2 position come determine rebuild scanning in the direction θ scanning range (Scan θ).
Since the heart (Fh) of fetus is repeated periodically expansion contractile motion, the drop shadow spread of heart (Fh) is added
Range obtained by blank region is as scanning range, so that more reliably by the heart in the reconstruction scanning in persistently multiple periods
Dirty (Fh) is included in scanning range.For example, concrete example as shown in FIG. 6 is such, by for from θ 1 to θ 2 drop shadow spread in θ
1 side and 2 side θ add the range obtained by the Δ as surplus from θ s to θ e as scanning range (Scan θ) respectively.In addition,
Can by it is shown in fig. 6 from θ 1 to θ 2 drop shadow spread directly as the direction θ scanning range.
In addition, in above-mentioned concrete example, although the heart (Fh) based on the fetus obtained according to the projected image of Fig. 6
The drop shadow spread in the direction θ determines the scanning range (Scan θ) in the direction θ, but can also determine fetus according to the projected image of Fig. 6
The drop shadow spread in the direction φ of heart (Fh) determine the scanning range in the direction φ.For example, it is also possible to determine by the direction φ
The two-dimensional scanning range that scanning range and the scanning range in the direction θ are constituted.In addition it is also possible to which region-of-interest configuration part 32 is set
The range (1~φ of φ 2) of the scanning direction φ of fixed region-of-interest (Fig. 2) is used as the scanning range in the direction φ.In addition, by Fig. 6
Projected image be shown in display unit 62, user can also specify the direction θ on one side confirming in the projected image that exists while the display
Scanning range and the scanning range in the direction φ.
Alternatively, it is also possible to the depth of the heart based on the row data decision fetus obtained by prescan.For example, it is also possible to
It is less than threshold value from shallower side (10 sides of probe) towards deeper side search echo data along the row data obtained by prescan
Partially (part corresponding with the chambers of the heart) and using the position searched for as the depth of heart.For example, it is also possible to passing through prescan
The depth of heart and multiple by obtaining according to multiple row data is determined respectively for each row data in the multiple row data obtained
Depth of the statistical value (for example, average value etc.) of depth as heart.
<rebuilding scanning>
Fig. 7 is the figure for indicating to rebuild the concrete example 1 of scanning.Reconstruction when probe 10 is 2D array probe is illustrated in Fig. 7
The concrete example of scanning.Transmitting-receiving process portion 12 executes weight in the three-dimensional space of the heart (Fh) comprising fetus by control probe 10
Scanning is built, reconstruction scanning repeats to make position on the direction θ (scanning direction) on one side in the multiple heartbeat of heart (Fh)
Variation forms the scanning of scanning surface on one side.
In rebuilding scanning, is formed using the direction r as the ultrasonic beam of beam direction (depth direction), pass through electron scanning
The Ultrasound beamforming scanning surface.In turn, in the case where 2D array probe, the periodically electronics motion scan on the direction θ
Ultrasonic beam is simultaneously scanned in scanning surface in face.
It is executed in the scanning range set by scanning range configuration part 36 and rebuilds scanning.For example, passing through scanning model
It encloses in the angular range in the direction φ of the setting of configuration part 36 and forms scanning surface.In addition, the angular range in the direction φ is also possible to close
Infuse the range (1~φ of φ 2) of the scanning direction φ for the region-of-interest (Fig. 2) that region setting part 32 is set.In turn, passing through scanning
In the scanning range (the Scan θ of Fig. 6) of slave θ s to the θ e in the direction θ that range configuration part 36 is set, make scanning surface in the direction θ on one side
On periodically mobile execute on one side rebuild scanning.
In reconstruction scanning in concrete example 1 shown in Fig. 7, that is, in the case where 2D array probe, by the direction θ
Scanning range is divided into multiple scanning areas (R1~R8).Also, it is more to pass through reception formation parallel respectively for each scanning area
A scanning surface.For example, on one side send from 1 while wave beam obtains multiple parallel receptions for receiving wave beam to the direction φ (ginseng
According to Fig. 2, Fig. 3) scanning ultrasonic beam (send wave beam and receive wave beam), it is intensively (arranged side by side respectively thus directed towards each scanning area
Ground) form multiple (for example, the 4) scanning surfaces for constituting the scanning area.
Also, according to the exchange-column shift of triggering represented by the trigger signal (being described in detail later) exported from trigger generator 70
Scanning area sequentially forms scanning surface in multiple scanning areas (R1~R8) and collects frame data.In turn, based on collected
Frame data execute reconstruction processing.
Fig. 8 is the figure of the collection and reconstruction processing for illustrating frame data (frame group).It is illustrated in (A) of Fig. 8 and passes through 2D
The concrete example for the frame data that the reconstruction scanning (Fig. 7) of array probe is collected.
In the concrete example shown in (A) of Fig. 8, connect parallel since passing through in scanning area R1 the timing of triggering (1)
Mesorelief is collected into such as 4 scanning surfaces, obtains the frame group that 4 frame data corresponding with 4 scanning surfaces are constituted.Also, it is sweeping
Frame group is collected until the timing of next triggering (2) in persistently multiple phases with retouching the position for not moving 4 scanning surfaces in the R1 of region.
As a result, for example, as shown in (A) of Fig. 8,4 frame data corresponding with phase 1 are successively obtained in scanning area R1
Frame group R1 (T2) that corresponding 4 frame data of the frame group R1 (T1) and phase 2 of composition are constituted, 4 frame numbers corresponding with phase 3

<setting of the condition of scanning>
The condition of scanning (Scan condition) in scanning (Fig. 7, Fig. 9) is rebuild in the setting of condition of scanning configuration part 40.Example
The setting of condition is scanned such as after prescan and before rebuilding scanning.
As the condition of scanning rebuild in scanning (Fig. 7, Fig. 9), the setting of condition of scanning configuration part 40 is on one side sweeping position
Retouch the repeat condition for changing the scanning for forming scanning surface on one side on direction (direction θ).In the case where 2D array probe, as sweeping
The number of repetition (scanning times) for the repeat condition setting scanning retouched, weight in the case where mechanical 3D probe, as scanning
The repetition time (sweep time) of multiple condition setting scanning.
Figure 10 is the figure of the repeat condition for illustrating to rebuild in scanning.Scanning direction (the side θ is illustrated in (A) of Figure 10
To) scanning range and depth is identical and scanning times or sweep time asynchronous comparative example.
In the comparative example of (A) of Figure 10, when scanning times are less or when sweep time is shorter, after constituting reconstruction processing
The frame sum obtained for rebuilding volume is less, and adjacent frame period is wider.In contrast, when scanning times are more or scanning
When time is longer, the frame sum obtained for rebuilding volume is more after constituting reconstruction processing, and adjacent frame period is relatively narrow.If constituting
The frame period for rebuilding multiple frames of volume is relatively narrow, then the resolution ratio of the scanning direction of the 3-D image obtained based on the reconstruction volume
It improves.
Illustrated in (B) of Figure 10 scanning direction (direction θ) scanning range and scanning times (sweep time) it is identical and
Diagnose the asynchronous comparative example of depth of object (heart of fetus).In the comparative example of (B) of Figure 10, when diagnosis object is shallower
When, constitute reconstruction processing after it is obtained rebuild volume multiple frames frame period it is narrow, but when diagnose object it is deeper when, should
Frame period is wider.Therefore, when diagnosis object is deeper, compared with shallower situation, based on the three-dimensional figure for rebuilding volume acquisition
The resolution ratio of the scanning direction of picture reduces.Therefore, condition of scanning configuration part 40 is according to the heart as the fetus for diagnosing object
The repeat condition in scanning is rebuild in depth setting.
Figure 11 is the figure of the setting of the corresponding repeat condition of depth for illustrating with diagnosing object.Condition of scanning configuration part
The interframe of 40 multiple frames to constitute reconstruction volume sets repetition in a manner of being divided into target frame period d corresponding with target resolution
Condition.It is, rebuilding volume when either still deeper when the heart of the fetus as diagnosis object is shallower to constitute
The interframe of multiple frames be divided into the mode of target frame interval d and set repeat condition.
In the setting of repeat condition, determines and constitute firstly, being for example based on target frame period d and depth D using formula 1
Rebuild treated rebuild volume the relevant frame period of multiple frames angle delta θ.
(formula 1) Δ θ=arcsin (d/D)
It is determined in the way of target resolution by the resolution ratio based on the scanning direction for rebuilding the 3-D image that volume obtains
Target frame period d.For example, using the resolution ratio of the faultage image (B-mode image) formed in faultage image forming portion 30 as mesh
Mark frame period d.For example, it is preferable to also correspondingly change the setting of target frame period d when switching the resolution ratio of B-mode image
Value.In addition, the user such as being also possible to doctor, laboratory technician can obtain the side of desired resolution ratio according to diagnosis content
Formula adjusts target frame period d.
Depth D is the depth of the heart of fetus, such as is determined based on the region-of-interest (Fig. 2) that the heart for fetus is set
Depth D.For example, the depth D by the depth (the depth D2 of Fig. 2) of the bottom of region-of-interest as the heart of fetus.In addition, for example
Region-of-interest can also be based on according to the depth (the depth D1 of Fig. 2) at the upper bottom of region-of-interest, center of region-of-interest etc.
Other positions determine the depth D of the heart of fetus.
Then, the scanning range (Scan θ) in scanning direction (direction θ) and the angle of frame period such as are based on using formula 2
Δ θ determines target frame number Fn needed for rebuilding volume.The scanning range of scanning direction is set by scanning range configuration part 36
(Scan θ) (referring to Fig. 6).
(formula 2) Fn=(Scan θ/Δ θ)+1
Also, condition of scanning configuration part 40 setting rebuild scanning in scanning times or sweep time as repeat condition with
Realize target frame number Fn needed for rebuilding volume.When probe 10 is 2D array probe, condition of scanning configuration part 40 utilizes formula 3
Determine scanning times, when probe 10 is that mechanical 3D pops one's head in, condition of scanning configuration part 40 determines sweep time using formula 4.
(formula 3) scanning times=(Fn/ receives number parallel)+1
(formula 4) sweep time=Fn × average period/receives number parallel
The parallel reception number of formula 3 and formula 4 is to rebuild in scanning by receiving the scanning surface intensively formed parallel
Quantity (for example, 4).In addition, the average period of formula 4 is average (common) cycle time relevant to the heartbeat of fetus,
Such as use scheduled preset value.It is of course also possible to suitably change the preset value.
Control unit 100 control transmitting-receiving process portion 12 with by scanning range configuration part 36 set scanning range according to
It is executed by the condition of scanning that condition of scanning configuration part 40 is set and rebuilds scanning (Fig. 7, Fig. 9).
For example, when probe 10 be 2D array probe when, by scanning range configuration part 36 set the direction θ slave θ s to
In the scanning range (referring to Fig. 7) of θ e, with touching corresponding with scanning times (formula 3) that is set by condition of scanning configuration part 40
It sends out number and executes reconstruction scanning.In addition, the concrete example of Fig. 7, Fig. 8 with from triggering (1) to trigger (9) triggering number (scanning times) 9
Reconstruction scan correspond to.In addition, the scanning range in the direction θ rebuild in scanning is divided into the case where 2D array probe
(triggering number -1) a scanning area.For example, it is preferable to which the scanning range in the direction θ is divided into (triggering number -1) a scanning area.And
And the scanning surface of number corresponding with number is received parallel is respectively formed for each scanning area.For example, in each scanning area with
(same scan interplanar distance) forms multiple scanning surfaces at equal intervals.In addition, the scanning face interval in each scanning area is (between scanning surface
Away from) not necessarily identical (at equal intervals), preferably determine scanning face interval (between scanning surface according to certain rule across multiple scanning areas
Away from).
Slave θ s to θ e when probe 10 is that mechanical 3D pops one's head in, in the direction θ set by scanning range configuration part 36
Scanning range (referring to Fig. 7) in executed with the sweep time (formula 4) set by condition of scanning configuration part 40 and rebuild scanning.
