Description
Technical field
The present invention relates to ultrasonic imaging technique field, specifically a kind of vapour Novel ultrasonic imaging system.
Background technology
Conventional Ultrasound imaging system comprises for transmitting ultrasonic beam and receiving the ultrasound transducer element array from the reflected beam of the object of studying.By selecting the amplitude of time delay (or phase place) and applied voltage, can control each element of transducer to produce ultrasound wave, ultrasound wave combines to form the clean ultrasound wave that the preferred vector direction in edge is advanced and concentrated on Chosen Point along wave beam.Repeatedly excite (firing) to can be used for gathering the data that represent same anatomical information.Can change that the wave beam that at every turn excites forms parameter so that for example by transmit continuous wave beam (wherein the focus of each wave beam with respect to the focus of last wave beam by displacement) along same scan row, for excite the content that the variation of maximum focal length is provided or otherwise more relocates the receiving data at every turn.By amplitude and the phase rotating of change applied voltage, can be in plane steerable and focus thereof with scanning object.
In the time adopting transducer array to receive the acoustic energy of reflection, apply identical principle.Be added in mutually the voltage that receiving element produces, so that net signal indicate ultrasonic that single focus from object reflects.The same with transfer mode situation, by giving the signal from each receiving element by independent phase place and gain, realize this concentrated reception of ultrasonic energy.Many conventional Ultrasound imaging systems have comprised two-dimensional transducer array (hereinafter referred to as 2D transducer array).For this disclosed object, 2D transducer array is defined by comprising the wherein transducer array of the central point formation two-dimensional pattern of element of transducer.According to some embodiment, two-dimensional pattern can be followed curved surface.Generally, element of transducer is similar dimensionally in 2D transducer array in length and width.In addition, 2D transducer array can have complete electron focusing and turn to (steering).2D transducer array generally comprises multiple element of transducers of arranging in grid; That grid can have is square, rectangle, hexagon or other basis.By controlling amplitude and the sequential of element in 2D transducer array, may in azimuth direction and short transverse, make the ultrasonic beam transmitting turn to simultaneously.The use of 2D transducer array allows ultrasonic transducer or probe to have greater flexibility.
Conventionally, collect ultrasound data by sustained wave doppler imaging pattern so that for imaging is favourable moving liquids such as blood.In sustained wave doppler imaging pattern, the one group of element of transducer transmitting in aperture (aperture) is used for ultrasonic energy to be sent to the just anatomic region in imaging.Second group of element of transducer in receiving aperture is separately for detection of the reflected ultrasound energy from just the regional reflex in imaging is returned.Generally, for the probe with 1D transducer array, have and amplifier that in receiving aperture, each element of transducer is associated.But, due to space and power constraint, generally there is limited dynamic range with the amplifier in the probe of 2D transducer array, they are not suitable for processes such as sustained wave doppler imaging very much.In sustained wave doppler imaging, from recently several orders of magnitude a little less than the signal of self-retaining tissue of the signal of movement blood.For suitable signal analysis, must process weak blood echo (echo) and strong tissue echo.Due to blood echo signal than a little less than the signal received of tissue many, therefore, use such as those amplifiers of finding etc. being processed to the signal of receiving during sustained wave Doppler gathers with the amplifier of limited dynamic range in the conventional transducer with 2D transducer array and can become problem.Conventionally, for being used, sustained wave doppler imaging will cause the inferior good analysis of blood echo with the amplifier of limited dynamic range.In addition, 2D transducer array General Requirements closely forms to obtain optimum efficiency near the electronics wave beam of transducer array.But conventional 2D array can have several thousand elements, therefore, it is infeasible for the formation of electronics wave beam that the signal of telecommunication is taken back to ultrasonic control station from all these elements.
