By the transmission system channel of parallel join is set, because the output voltage transmitting by transmission line 252 is taken from the meansigma methods of 4 supply sources, can obtain higher current capacity and transmission wave more clearly, therefore there is lower noise level.Therefore,, when transmission system channel configuration becomes 4, noise decrease factor is 4=2.In this specific embodiment, for example, according to the relevant current capacity of the signal transmission to transmission channel and predeterminated voltage noise level (average voltage noise level), can use 4 transmission channels.
Receiving circuit 270 comprises the 49 system channel 272-the 64 system channels 274 of parallel join.Receive line 276 and from receiving unit 105, be transferred to 16 receiving system channel 272-274 arranged side by side by receiving signal.In addition,, in receiving the process of signal, all receiving system channels have identical time delay (just as continuous wave Beam-former 110).Receiving system channel 272-274 is connected in successively the probe arranging on probe connector interface 202 and receives coupling assembling 261,262,263 etc., and by probe, receive the interface that arranges on coupling assembling 261-263 and probe interface and receive coupling assembling 264-266 and interconnect, receive coupling assembling 264-266 and transfer in the receptor 108 with its interconnection receiving signal.
By the receiving system channel of parallel join is set, voltage noise level be take the square root of receiving system channel in parallel and is doubly that factor reduces, in this embodiment, for rely on receiving system channel in parallel, receiving system channel can form an input value that inputs to continuous wave Beam-former 110, than the ultrasonic device only with a receiving system channel, has larger dynamic range.At this, input to the dynamic range of the input signal of continuous wave Beam-former 110, can be regarded as by what process bandwidth is maximum input value and the ratio that receives the inherent voltage noise figure of signal.
In addition, also impedance matching circuit can be set, for example transducer 278, be arranged at receiving unit (with receiving line 276 interconnection), with generate to need or during predeterminated voltage noise figure, the resistance value of conversion receiving unit 105, makes receptor 108(for example connect load) dynamic range maximize.Other assemblies form impedance matching circuit.In as the embodiment of Fig. 2, conversion ratio can be selected, so that the heat noise of the electrical impedance that comes from receiving unit 105 of conversion is about 2 times of equivalent input quantity of receptor 108.
In addition, inductance 280 also can be used in receiving unit to eliminate the electric capacity of system channel 272-274 arranged side by side.
Optionally, can make electric capacity be connected in receiving system channel.As shown in Figure 2, electric capacity 282-284 can be connected to the 49 system channel 272-the 64 system channel 274.Electric capacity 282-284 is connected with receiving unit 105 by the reception line 276 connecting respectively separately.Electric capacity 282-284 can be used for intercepting when needed DC component according to the design of receptor 108.
