Abstract
The invention relates to a B-type ultrasonic wave principle demonstration experiment instrument for teaching. A cylindrical organic glass water tank and a specially-made two-dimensional movable measuring frame are provided. An ultrasonic probe placed on a vertical moving ruler of the two-dimensional movable measuring frame and an object to be measured are together immersed below a water surface of the cylindrical organic glass water tank. When the ultrasonic probe sends ultrasonic waves to the object to be measured, a horizontal servo stepping motor and a vertical servo stepping motor can drive the ultrasonic probe to continually measure in a moving mode on a two-dimensional surface in order to obtain a two-dimensional tangent plane sonograms of the object to be measured.
Description
Technical field
The present invention relates to the teaching and experiment equipment of B ultrasound principle aspect in a kind of physics, especially a kind of teaching B ultrasound principle demonstration experiment instrument.
Background technology
With ultrasound wave the testee inner structure being carried out Non-Destructive Testing is a kind of novel technology, especially can scan and all a lot of with the equipment of the medical treatment such as briliancy modulation shows or color modulation shows common B ultrasound diagnostic equipment, color doppler flow imaging diagnostic equipment and various B ultrasound detectors and industrial detection two-dimentional tangent plane picture.All do not have but be specifically designed on the experimental apparatus market of B ultrasound class of element of instruction explanation, only have the instrument of complex structure, expensive real B ultrasound class on the market.In order to remedy the in this respect deficiency of teaching and experiment equipment, the present invention proposes a kind of B ultrasound principle demonstration experiment instrument of the usefulness of imparting knowledge to students, can make the student understand intuitively the principle of the B ultrasound imaging of more complicated by relative simple experiment device, thereby the development that promotes experimental teaching and scientific research is had positive meaning.
Summary of the invention
Right cylinder tank with an organic glass, soak object to be detected (this object can have profile and the inner structure of more complicated) below the water surface in tank, be installed in by computer control, under water to testee emission ultrasound wave by the ultrasonic probe of the special use on the two-dimensional movement measurement bay of driven by servomotor with one again, realize that by the continuous moving up and down of two-dimensional movement measurement bay ultrasonic probe is to the two-dimensional movement scanning survey of measured object.Pass through ultrasound wave in the analysis of interior of articles by the different formed various echoes of material of each several part density again, after machine transforms as calculated the range signal of various different echoes being become luminance signal shows at computer screen, just the complicated structure of testee inside is shown thus, reached the teaching purpose of B ultrasound image-forming principle.
Be described below respectively about measurement ultimate principle and the main design idea of this teaching with B ultrasound principle demonstration experiment instrument.
The measurement ultimate principle of B ultrasound imaging: the English of B ultrasound is called (brightness modulation mode ultrasonic), means: the ultrasound wave of brightness mode display mode.When ultrasound wave transmits in adjacent two media structure, can produce echo reflection because acoustic impedance is different at two medium interfaces, B ultrasound is exactly bright that changes being converted into the power of brightness with signal after the different echo-pulse electric signal amplifications, represents different dielectric structures with this.Simultaneously, the acoustic beam of Type B ultrasound emission adopts the form to the scanning of measured object continuous moving, and to consist of width of cloth two dimension tangent plane ultrasonogram, then the gauger just can judge according to the result of ultrasonogram gained the overall picture of the inner structure of measured object.
This teaching with the main design idea of B ultrasound principle demonstration experiment instrument is: B ultrasound Image-forming instrument common, relative complex is displayed with fairly simple device, and the form of displaying will be tried one's best intuitively, so that teaching.
Teaching of the present invention is characterized in that with B ultrasound principle demonstration experiment instrument: this experiment instrument includes a cylindrical organic glass tank and ultrasonic probe, special two-dimensional movement measurement bay, testee, these several parts of test desk of experiment usefulness.
Described teaching B ultrasound principle demonstration experiment instrument, it is characterized in that: the special two-dimensional movement measurement bay that comprises is by vertical attachable mechanical stage and move horizontally chi two parts and be combined into, these two attachable mechanical stage parts consist of two independently mobile control systems with servo step motor respectively again together, two servo step motors move with the slide block that the screw rod of two attachable mechanical stage inside is connected to drive on the attachable mechanical stage respectively by rotation, and these two servo step motors all are subjected to computer control.
Described teaching B ultrasound principle demonstration experiment instrument, it is characterized in that: vertical attachable mechanical stage is that vertical attachable mechanical stage is installed on the slide block that moves horizontally chi with moving horizontally the two-part array mode of chi on the two-dimensional movement measurement bay that comprises, and ultrasonic probe then is installed on the slide block of vertical attachable mechanical stage.
Described teaching B ultrasound principle demonstration experiment instrument, it is characterized in that: the chi that moves horizontally of the special two-dimensional movement measurement bay that comprises is that frame is on the slide block on edge on the cylindrical organic glass tank.
The present invention solves the main technical schemes that its technical matters adopts: design a cylindrical organic glass tank and a special two-dimensional movement measurement bay, the ultrasonic probe and the testee that are installed on the vertical attachable mechanical stage of two-dimensional movement measurement bay are immersed in below the water surface of cylindrical organic glass tank together, launching hyperacoustic while to testee by ultrasonic probe, horizontal servo stepper motor and vertical servo step motor can drive ultrasonic probe and do the two-dimentional tangent plane ultrasonogram that continuous moving measures to obtain testee at two dimensional surface.
The invention has the beneficial effects as follows, can make the student understand intuitively the principle of the B ultrasound imaging of more complicated by relatively simple experimental provision, thereby the development that promotes experimental teaching and scientific research is had positive meaning.
