Detailed description of the invention

Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated.

As shown in Figure 1, in the method and device embodiment of the reduction power consumption for ultrasonic system of the present invention, the method comprises the steps:

Step S11 obtains Current Scan initiation parameter: in general, and typical ultrasound emission and receiving system comprise probe (transducer group), transmitting chip group (transmission channel), receiving chip group (receive path), beam synthesizer, image procossing and master controller.Its workflow is as follows: master controller issues in scanning mode and transmits and receives relevant parameter, and scanning starts, and beam synthesizer controls to launch, and beam synthesizer controls to receive, Beam synthesis, image procossing.And in the present embodiment, need the state distinguishing transmitting chip and the receiving chip worked in each time period in scanning process, low-power consumption process is carried out to certain some time periods idle chip, thus reaches reduction power consumption, reduce the object of temperature rise.In addition, also needing to judge or obtain to participate in present scan or the chip that do not participate in or passage, realizing the accurate control to passage when not affecting scanning.And the state of these passages in present scan will be judged, need to calculate it according to sweep parameter.So, in this step, obtain the scanning initiation parameter of present scan, for follow-up calculating is prepared.In the present embodiment, be first that master controller initializes relevant parameter in scanning process, be transferred to beam synthesizer; Beam synthesizer receives scanning initialization correlation coefficient and loads, and these parameters comprise scanning wire size, scanning transmitting aperture scope, scanning receiving aperture scope, scan depths etc.In this step, these parameters are obtained by above-mentioned beam synthesizer.

Step S12 is according to Current Scan initiation parameter, calculate the transmission channel participating in and have neither part nor lot in emission scan: in this step, owing to obtaining scanning initialized parameter, these parameters have in fact embodied the characteristic of emission scan, that is, by these parameters, the various parameters of emission scan are in fact defined.In this step, exactly by calculating these parameters, obtain scanning that carry in initiation parameter, to emission scan definition, thus this emission scan accomplished needs the transmission channel that relates to, thus obtain participating in the transmission channel of this emission scan and having neither part nor lot in the transmission channel of this emission scan.As for concrete computational process, describing in detail after a while.

The transmission channel having neither part nor lot in emission scan is placed in low-power consumption mode by step S13: in this step, the transmission channel having neither part nor lot in this emission scan through above-mentioned steps is placed in low-power consumption mode by system, the transmission channel participating in this emission scan is placed in mode of operation, and carries out this emission scan.In the present embodiment, above-mentioned mode of operation comprises for this passage provides normal voltage to supply; Low-power consumption mode then comprises the power supply that cuts off this passage or is only this by providing a lower supply voltage, makes its cisco unity malfunction, thus reduces power consumption.

As shown in Figure 2, in above-mentioned steps, the concrete steps being participated in and have neither part nor lot in the transmission channel of this emission scan comprise:

Step S21 is according to scanning wire size and emission scan aperture, obtain starting point and the end point of effective transmitting aperture: in this step, according to scanning wire size, scanning transmitting aperture scope, calculate effective transmitting aperture, namely obtain starting point and the end point of effective transmitting aperture.Refer to Fig. 3, Fig. 3 is the structural representation in emission scan aperture.In figure 3, scanning wire size is A0, and scanning transmitting aperture scope is n0, and the total transmitting aperture size of system is 0 ~ M0, and effective transmitting aperture starting point is P0, and effective transmitting aperture end point is Q0, between P0 ~ Q0, is effective aperture scope; 0 ~ P0 and Q0 ~ M0 is invalid transmitting aperture scope.Being calculated as follows of P0, Q0 point:

$P0=\left\{\begin{array}{c}0,(A0\&le;\left(\frac{n0}{2}\right))\\ A0-\left(\frac{n0}{2}\right),(A0>\frac{n0}{2})\end{array}\right.$

$Q0=\left\{\begin{array}{c}M0,(A0\&GreaterEqual;M0-\left(\frac{n0}{2}\right))\\ A0+\left(\frac{n0}{2}\right),(A0<M0-\left(\frac{n0}{2}\right))\end{array}\right.$

Like this, in this step, starting point and the end point of above-mentioned effective transmitting aperture can just be obtained.In the present embodiment, just instead can release invalid transmitting aperture by effective transmitting aperture P0 ~ Q0, also just can calculate the transmitting chip of low-power consumption process simultaneously.

Step S22 is according to the starting point obtained and end point, obtain the transmission channel participating in this emission scan, and then obtain the transmission channel that has neither part nor lot in: in this step, according to the effective transmitting aperture starting point obtained and end point, obtain the transmission channel participating in this emission scan; That is, effective aperture scope and invalid pore diameter range is obtained in this step in above-mentioned steps, itself and transmission channel are carried out changing (for a system, above-mentioned aperture and transmission channel are all changeless), thus obtain emission scan passage corresponding to these pore diameter ranges.

The relation of step S23 foundation transmission channel and transmitting chip, participated in and had neither part nor lot in the transmitting chip of this emission scan: in this step, by the corresponding relation of transmission channel and transmitting chip, determine participate in the transmitting chip of this emission scan and have neither part nor lot in the transmitting chip of this emission scan.Be 0 ~ P0 and Q0 ~ M0 owing to having obtained invalid transmitting aperture in above-mentioned steps, and the port number that each transmitting chip connects is x0, the numerical aperture that namely each transmitting chip is corresponding is also x0, and the transmitting chip number X0 of so low-power consumption process is

X0＝fix(P0/x0)+fix((M0-Q0)/x0)

The transmitting chip scope of low-power consumption process is equally also in the scope that invalid transmitting aperture 0 ~ P0 and Q0 ~ M0 is corresponding.Low-power consumption process (making it enter low-power consumption mode) is carried out for the transmitting chip be within the scope of the invalid transmitting aperture of 0 ~ P0 and Q0 ~ M0, for the transmitting chip be within the scope of the effective transmitting aperture of P0 ~ Q0, then enters scan control.In the present invention, regardless of for transmission channel or receive path, the numbering of the passage of each chip connection or correspondence is setting in advance, therefore, after knowing the number of channels (pore diameter range) that this is launched or reception uses, as long as know this launch or receive central passage (this passage is determined usually, constant), just can obtain the channel number needing in this transmitting or reception to open or close, also just can determine that this is launched or receives the chip that needs open or close (making it enter low-power consumption mode), and then it is operated accordingly.

In the present embodiment, although perform the power consumption that above-mentioned steps just can reduce system to a certain extent, the object reducing power consumption is realized to a certain extent.But, in order to reduce system power dissipation further, after or above-mentioned steps can also being performed while execution above-mentioned steps, similar above-mentioned step is also performed to reception scan channel.As shown in Figure 4, the process receiving scan channel is comprised the steps:

Step S41 is according to Current Scan initiation parameter, calculate the receive path participating in and have neither part nor lot in and receive scanning: in this step, exactly by calculating Current Scan initiation parameter, obtain scanning that carry in initiation parameter, to reception scanning definition, thus accomplished this receives the receive path scanning and need to relate to, thus obtain participating in receive path of this reception scanning and having neither part nor lot in the receive path of this reception scanning.As for concrete computational process, describing in detail after a while.

Step S42 is placed in low-power consumption mode by having neither part nor lot in the receive path receiving scanning: in this step, this receive path receiving scanning that has neither part nor lot in through above-mentioned steps is placed in low-power consumption mode by system, be placed in mode of operation by participating in this receive path receiving scanning, and carry out this reception scanning.In the present embodiment, above-mentioned mode of operation comprises for this passage provides normal voltage to supply; Low-power consumption mode then comprises the power supply that cuts off this passage or is only this by providing a lower supply voltage, makes its cisco unity malfunction, thus reduces power consumption.

Wherein, as shown in Figure 5, in the present embodiment, participated in and had neither part nor lot in these concrete steps receiving the reception scan channel of scanning to comprise:

Step S51 is according to scanning wire size and receive scan aperture, obtains starting point and the end point of effective receiving aperture: in this step, and according to scanning wire size, scanning receiving aperture scope, calculates effective receiving aperture.The position view of receiving aperture as shown in Figure 6, in figure 6, scanning wire size is A0, scanning receiving aperture scope is n1, the total receiving aperture size of system is 0 ~ M1, and effective receiving aperture starting point is P1, and effective receiving aperture end point is Q1, P1 ~ Q1 is effective aperture scope, and 0 ~ P1 and Q1 ~ M1 is invalid receiver pore diameter range.Being calculated as follows of P1, Q1 point:

$P1=\left\{\begin{array}{c}0,(A0\&le;\left(\frac{n1}{2}\right))\\ A0-\left(\frac{n1}{2}\right),(A0>\frac{n1}{2})\end{array}\right.$

$Q1=\left\{\begin{array}{c}M1,(A0\&GreaterEqual;M1-\left(\frac{n1}{2}\right))\\ A0+\left(\frac{n1}{2}\right),(A0<M1-\left(\frac{n1}{2}\right))\end{array}\right.$

By above-mentioned calculating, just can obtain this starting point receiving scanning and end point, thus obtain receiving the effective receiving aperture in scanning at this, i.e. effective receiving aperture P1 ~ Q1.According to starting point and the end point of above-mentioned receiving aperture, just instead can release invalid receiver aperture, also just can calculate the receiving chip of low-power consumption process simultaneously.

Step S52 is according to the starting point obtained and end point, obtain participating in the receive path that this receives scanning, and then obtain the receive path that has neither part nor lot in: similarly, in this step, just can obtain participating in this according to the effective receiving aperture obtained in above-mentioned steps to receive scanning and have neither part nor lot in the receive path that this receives scanning.

The relation of step S53 foundation receive path and receiving chip, participated in and had neither part nor lot in the transmitting chip that this receives scanning: the reason same with emission scan, what finally control is the receiving chip of system, so in this step, need the corresponding relation according to receiving chip and receive path, by participating in or have neither part nor lot in the receive path that this receives scanning, be converted to corresponding receiving chip.Be 0 ~ P1 and Q1 ~ M1 owing to having obtained invalid receiver aperture in above-mentioned steps, and the port number that each receiving chip connects is x1, the numerical aperture that namely each receiving chip is corresponding is also x1, so needs the transmitting chip number X1 of low-power consumption process to be

X1＝fix(P1/x1)+fix((M1-Q1)/x1)

The receiving chip scope of low-power consumption process is equally also in the scope that invalid receiver aperture 0 ~ P1 and Q1 ~ M1 is corresponding.Low-power consumption process is carried out for the receiving chip be in 0 ~ P0 and Q0 ~ M0 invalid receiver pore diameter range, for the receiving chip be within the scope of the effective receiving aperture of P0 ~ Q0, then enters scan control.

It is worth mentioning that, after executing above-mentioned steps, system enters scan control state, and the transmitting, the receive path that control above-mentioned participation scanning carry out ultrasonic scanning, obtain ultrasound data.After entering above-mentioned state, system can be divided into again in scanning process and not two kinds of situations in scanning process.If system is in scanning process, comprise again two kinds of situations, one carries out emission scan, and in this case, system makes all receive paths enter low-power consumption mode, and meanwhile, the transmission channel having neither part nor lot in emission scan is also in low-power consumption mode; Another kind carries out reception scanning, and in this case, system makes all transmission channels enter low-power consumption mode, meanwhile, has neither part nor lot in the receive path receiving scanning and be also in low-power consumption mode.If system is not in scanning process, then represents and stop scanning, now, the receive path that system closing is all and transmission channel.The power consumption of these ultrasonic systems be arranged so that in the present embodiment reduces further, and caloric value also reduces further simultaneously, makes when not affecting the signal to noise ratio of ultrasonic signal, the power consumption of further reduction system.
