In triggering circuit for generating, with the rated frequency fr Hz (cycle specified; 1/fr second) repeatedly occur for the formation of the hyperacoustic trigger impulse of transmission.In addition, in the delay circuit, for each passage, ultrasound wave is assembled fasciculation also to determine to be supplied to each trigger impulse the time delay sent needed for directivity.Pulse-generator circuit applies driving pulse with the timing based on this trigger impulse to probe 12.
In addition, the scanning sequence of ultrasound wave transmitting element 21 in order to put rules into practice according to the instruction of control processor 28, and have can instantaneous change transmission frequency, send the function such as driving voltage.Especially for the change sending driving voltage, by can the transtation mission circuit of linear amplification type of instantaneous its value of switching or the TURP mechanism that changes multiple power subsystem realize.
Ultrasonic wave receive unit 22 has not shown amplifying circuit, A/D converter, adder etc.In amplifying circuit, for each passage, the echo-signal be taken into via probe 12 is amplified.In A/D converter, the echo-signal be exaggerated is determined to receive directivity, and provide and carry out receiving time delay needed for dynamic focusing, in adder, carry out additions afterwards process.By this addition, emphasize the reflecting component from the corresponding direction of the reception directivity to echo-signal, and according to receiving directivity and sending the comprehensive wave beam that directivity forms ultrasound wave transmission and reception.
B-mode processing unit 23 receives echo-signal from receiving element 22, and implements logarithmic amplification, envelope detection process etc., and generates the data being showed signal intensity by the light and shade of brightness.
Doppler processing unit 24 detects blood flow signal according to the echo-signal received from receiving element 22, and generates blood flow data.The detection of blood flow signal is undertaken by CFM (Color Flow Mapping: color flow angiography) usually.Now, resolve blood flow signal, try to achieve the blood flow informations such as average speed, dispersion, energy as blood flow data with regard to multiple spot.
RAW data storage 25 uses the B-mode data received from B-mode processing unit 23, the blood flow data received from doppler processing unit 24, generates the B-mode RAW data of each frame, blood flow RAW data respectively.In addition, RAW data storage 25 is changed by execution RAW voxel as required, thus from RAW data genaration volume data.
Graphics processing unit 28, for the RAW data received from RAW data storage 25, performs scan conversion process etc.In addition, graphics processing unit 28, for the volume data received from RAW data storage 25, carries out the image procossing of the regulations such as volume drawing, many sections conversion display (MPR:Multi PlanarReconstruction: multiplanar reconstruction), maximum value projection display (MIP:Maximum IntensityProjection).In addition, in order to make the connection of noise reduction or image excellent, two dimensional filter can be inserted after graphics processing unit 28, carrying out spatial smoothing processing.
Display processing unit 28, for the various view data generated in graphics processing unit 28, process, performs various dynamic range, brightness, contrast, gamma curve correction, RGB conversion etc.
Control processor 29 has the function as information processor (computer), controls the action of this ultrasonic image diagnostic apparatus main body.
Memory element 31 store apparatus control program, diagnostic message (comment etc. of patient ID, doctor), diagnosing protocol, transmission and reception condition, for realizing the program of speckle removing function, body mark generator and other data sets.In addition, as required, also may be used for the image etc. in keeping RAW data storage.In addition, memory element 31 also stores finger print information, the case information of those who are investigated P, and the finger print information of operator.The finger print information of those who are investigated P is associated with its case information, and the case information of the detected person P that the finger print information of operator is then checked with this operator is associated.In addition, the data of memory element 31 can via interface unit 32 externally peripheral device transmission.
Interface unit 32 is and input equipment 13, network, interface that new external memory (not shown) is relevant.Data and the analysis results etc. such as the ultrasonography obtained by this device by interface unit 32, can send other devices to via network.
Fig. 2 is the schematic perspective view of the ultrasound probe of this utility model embodiment, and Fig. 3 is a cross sectional representation of Fig. 2 housing.
As shown in Figure 2,3, ultrasound probe 12 has housing 120, and in this utility model embodiment, the cross section listing housing 120 is rectangle, also can be square.Be disposed with piezoelectric vibrator 12d in housing 120, the arrangement of piezoelectric vibrator 12d forms scanning direction Y and the lens direction X of ultrasound probe 12.The arrangement architecture of Fig. 3 to be piezoelectric vibrator 12d be one-dimensional array.
Housing 120 comprises the first shell 12a and second housing 12b that can fasten and be installed together, and the face (i.e. die joint 12c) that the first shell 12a and second housing 12b docks is positioned on the X of lens direction.The die joint 12c of the first shell 12a is formed with tongue-and-groove, the die joint 12c of second housing 12b is formed with plug tenon, by plug tenon and tongue-and-groove, the first shell 12a and second housing 12b is fastened togather.
In such cases, by the wall thickness reduction of housing 120 in scanning direction, and original thickness can be kept at the wall thickness of lens direction X, under maintenance housing 120 size, increase space as far as possible, meet plug tenon and tongue-and-groove coordinate required for size and requirement of strength.
Like this, the wall thickness of housing 120 in scanning direction is just less than the wall thickness at lens direction X, and the space of housing 120 inside is just expanded in scanning direction, thus just can increase the quantity of piezoelectric vibrator 12d further at scanning direction Y.Such as, as shown in Figure 3, piezoelectric vibrator 12d, after wall is thinning, is 7 in the quantity of scanning direction Y, and do not have thinning before quantity be 6.Although carried out concrete numerical example to piezoelectric vibrator 12d here to illustrate, this has been only schematically showing, not for restriction of the present utility model of carrying out as an example.The quantity that piezoelectric vibrator 12d arranges is determined as the case may be.
Thus, because the space of housing 120 inside increases, just can arrange some piezoelectric vibrators 12d more, which adds number of channels, thus ultrasonic portrait quality can be improved.
In addition, owing to there is no section at scanning direction Y housing 120, therefore can try one's best more thinning, and the requirement of strength of housing 12 can be met.
Fig. 4 is the another kind of structural representation of piezoelectric vibrator arrangement in housing.
For piezoelectric vibrator 12d, can be the arrangement of one-dimentional structure as shown in Figure 3, also can be the arrangement of two-dimensional structure as shown in Figure 4, the die joint 12c of housing 120 and the wall of scanning direction Y thinning mode in the same manner as above.Namely die joint 12c is positioned on the wall of lens direction X of housing 120, and housing 120 is less than the thickness at lens direction X at the thickness of the wall of scanning direction Y.
Although be illustrated embodiment of the present utility model above, these embodiments are pointed out as an example, and do not attempt the scope limiting utility model.These new embodiments can be implemented in other various modes, in the scope of purport not departing from utility model, can carry out various omission, displacement and change.These embodiments or its be out of shape be contained in utility model scope and purport in, and be contained in Patent request the utility model described in scope and with in the scope of its equalization.
