In the present embodiment, from the outlet side branch of phase modulation add circuit 14 ultrasound wave received signal frame data selection portion 19 and displacement measurement portion 20 are set, and be set up in parallel pressure measxurement portion 21 with it, back segment in this pressure measxurement portion 21 and displacement measurement portion 20 is provided with distortion and elastic modelling quantity operational part 23, back segment at distortion and elastic modelling quantity operational part 23 is provided with elastic data handling part 24 and chromoscan transducer 25, is provided with at the outlet side of black and white scan converter 16 and chromoscan transducer 25 and switches adder 17.Operators etc. can carry out freely controlling to chromoscan transducer 25 via device control interface portion (not shown).
Ultrasound wave received signal frame data selection portion 19, to be kept at successively from the ultrasound wave received signal frame data that phase modulation add circuit 14 is exported by timeliness successively with the frame rate of ultrasonic imaging apparatus in the frame memory that ultrasound wave received signal frame data selection portion 19 possessed (the ultrasound wave received signal frame data that make current preservation are as ultrasound wave received signal frame data N), the ultrasound wave received signal frame data N-1 of control command according to ultrasonic imaging apparatus from passing by in time, N-2, N-3, select ultrasound wave received signal frame data (with it as ultrasound wave received signal frame data X) among the N-M, and to 20 a pair of ultrasound wave received signal frame data N of output and the ultrasound wave received signal frame data X of displacement measurement portion.Signal from phase modulation add circuit 14 output is not limited to ultrasound wave received signal frame data, can also be for example to become the signal of form that the ultrasound wave received signal is carried out I, the Q signal of combined demodulation.
Ultrasound wave received signal frame data selection portion 19 obtains the cycle information between selected a pair of ultrasound wave received signal frame data N, the X, oppresses the pressing action of structure 22 automatically according to this periodic Control.One example of this action below is described.
By the cycle between ultrasound wave received signal frame data selection portion 19 selected a pair of ultrasound wave received signal frame data N, the X, by from phase modulation add circuit 14 output and to cycle of the ultrasound wave received signal frame data of ultrasound wave received signal frame data selection portion 19 inputs, with the ultrasound wave received signal frame data X in the past that is constituting these a pair of ultrasound wave received signal frame data and current ultrasound wave received signal frame data N between the ultrasound wave received signal frame data number of interval rejecting determined.For example, at the ultrasound wave received signal frame data as the output of phase modulation add circuit 14 is the cycle of per second 40 frames, and when the rejecting frame number of the interval between a pair of ultrasound wave received signal frame data N, the X was 1 frame, the frame rate between a pair of ultrasound wave received signal frame data became per second 20 frames.Automatically compressing structure 22 obtains the cycle information between this a pair of ultrasound wave received signal frame data N, X, and controls the compressing speed of pressing action based on resulting cycle information.
For example, under these conditions, be per second 40 frames as frame rate from the ultrasound wave received signal frame data of the output of phase modulation add circuit 14, and when the frame rate between a pair of ultrasound wave received signal frame data N, the X is per second 20 frames, suppose the tissue of being concerned about oppressed continuously with compressing speed V0 that the distortion of this compressing speed V0 generation 0.7% is the amount distortion that is suitable for high image qualityization.In this case, image-forming condition by the change ultrasonic imaging apparatus, thereby in the time will changing to the frame rate of per second 20 frames as the frame rate from the ultrasound wave received signal frame data of the output of phase modulation add circuit 14, the frame rate between a pair of ultrasound wave received signal frame data N, the X reduces by half and is per second 10 frames.At this moment, still oppress with compressing speed V0, because be 2 double-length degree the blanking time between the ultrasound wave received signal frame data, the distortion of therefore giving the tissue of being concerned about becomes greatly to 1.4%, has broken away from the scope of the amount distortion that is suitable for high image qualityization.As a result, the successive elastic image data of being exported become disorderly image.
Therefore, in the automatic compressing structure 22 of present embodiment, obtain the cycle information of ultrasound wave received signal frame data, for example under above-mentioned condition, compressing speed is changed to the compressing speed that reduces by half to V0/2.Thus, by the image-forming condition of change ultrasonic imaging apparatus,,, can control pressing action automatically to become best compression speed in order to obtain the elastic image of high image quality even under the situation of ultrasonic transmission/reception cyclomorphosis.
In addition, oppress structure 22 automatically, can switch compressing speed arbitrarily or the decrement (amplitude) of integration or the setting of the isobaric work forced to move of pressure threshold that pressing action stops in successive pressure process/decompression process.
Displacement measurement portion 20, based on carrying out one dimension or two-dimensional correlation processing by ultrasound wave received signal frame data selection portion 19 selected a pair of ultrasound wave received signal frame data, and the displacement of each measurement point on the measurement faultage image or mobile vector (direction of displacement and size), and generate the displacement frame data.As the detection method of this mobile vector, module coupling (block matching) method and gradient method of record in the patent documentation 1 for example arranged.The module matching method is, image is divided into the module of for example being made up of N * N pixel, the module of from frame before, being paid close attention in search and the current frame recently like module, and carry out predictive coding with reference to this module.
Pressure measxurement portion 21 measures or infers to tested 1 the imaging object position applied pressure of having a medical check-up.Pressure measxurement portion 21, measurement has applied the pressure of what degree to the head and tested the having a medical check-up of the probe of ultrasound probe 10 between 1, for example its structure can be the side that the pressure transducer that will detect the pressure that bar-like member bore is installed in the head of probe, arbitrarily the time, measure the head and the tested pressure of having a medical check-up between 1 of probe mutually, and the force value of being measured is sent to distortion and elastic modelling quantity operational part 23.Kind to the compressing pick off is not particularly limited, and for example can use the pressure transducer of capacitance type or resistance line style.
Distortion and elastic modelling quantity operational part 23, according to the distortion and the elastic modelling quantity of each measurement point on displacement frame data of exporting respectively from displacement measurement portion 20 and pressure measxurement portion 21 (amount of movement) and the pressure computing faultage image and generate distortion or the numeric data of elastic modelling quantity (elasticity frame data), with it to 24 outputs of elastic data handling part.The computing of the distortion of carrying out about distortion and elastic modelling quantity operational part 23 for example, just can be calculated and obtains by its displacement being carried out space differentiation, and does not need the data of pressure.And,, can just can obtain by the stress (pressure) that removes each computing point with the amount distortion of each computing point according to following formula about the computing of a kind of for example Young's modulus Ym in the elastic modelling quantity.
Ymij=pressure (stress) ij/ (amount distortion ij)
(i，j＝1，2，3……)
At this, i, the coordinate of the index expression frame data of j.
