Description
Technical field
The invention belongs to medical ultrasound technical field, the timing for relating generally to a kind of ultrasonic device scanning repetition layout line is matched
Set method and configuration system.
Background technique
Color ultrasonic devices become the indispensable auxiliary diagnosis of modern medicine with its exclusive real-time dynamic characteristic
One of means become the judgment criteria of certain illnesss in clinical diagnosis.
As shown in Figure 1, it is low expression that Freeze signal, which is that the stage is freezed in high expression, in the working timing figure of ultrasonic device
Ultrasonic device is in the scanning stage, and trig signal indicates the scanning of a line number evidence each time, and N root line signal combines to form one
Width ultrasound image；In general, each scanning line all has a corresponding configuration information, in the ultrasonic device course of work, trig
High period between send the corresponding configuration information of current scanning line in corresponding hardware, waveform is sent between low period
And receive echo data.Specifically, during Freeze signal is high, the corresponding configuration information of all scanning lines organizes one by PC
Secondary property is issued in slave computer DDR memory device (Double Data Rate Double Data Rate), when scanning, the next owner
Chip FPGA (Field-Programmable Gate Array, field programmable gate array) is controlled according to the line of current scanning line
Number and wire length parameter find and need to read scanning line position, and its corresponding configuration information is read out in trig high level
Period issues.
In the prior art, the DDR storage free time is swept plug wire configuration data and is divided into several memory blocks, each trig high level
The data of one memory block of capital parsing, i.e., the configuration information of one scanning line, and in the failing edge of trig, it reads next and sweeps
The corresponding configuration information of scanning line looked into is stored in fifo (First Input First Output, First Input First Output), with
It is parsed between trig high period next time.
As shown in connection with fig. 2, in t0 period, the corresponding configuration information of system analysis nth root scanning line, current DDR wire size
Count is incremented, at the t1 moment, the configuration information of N+1 root scanning line is read from DDR and is stored in fifo, at t3 moment, i.e. N+
The rising edge of 1 scanning line trig, count is incremented for current DDR wire size, the corresponding configuration information of parsing N+1 root scanning line, when t4
It carves, the configuration information of N+2 root scanning line is read from DDR and is stored in fifo.
However, being considered based on product cost, DDR is also used for caching while the memory as scanning configuration information
The caching of echo data, in this way, configuration information is run through with prestissimo, otherwise, if waited until back after the failing edge of trig
Wave number may will affect reading and writing data according to arriving；Correspondingly, the rising edge in trig needs that the wire size and length of scanning line will be read
Degree calculates, and reads at once in trig failing edge；So, it is had a problem that in timing, in the prior art only current
When trig high level, just know whether the line needs to repeat scanning, and current configuration information has been parsed and is given at this time
, it is desirable to it reads again once primary it is necessary to be read again from DDR；As shown in Fig. 2, some time point in t3 needs line_
Num is set as the reading position of N+1, the cumbersome and prone error in this way, timing Design is got up.
In prior art, maximum defect be when be resolved to when front configuration data need repeat read when, at this time
It has issued configuration information and has been ready to start to execute scanning next time, wire size information has jumped to next scanning line, no
The configuration information sent is repeated conducive to needs are looked for；In the prior art, general solution is if desired to a certain scanning
Line repeats scanning, then needs in advance that Coutinuous store is multiple in DDR by the configuration information of scanning line, in this way, largely waste DDR
Storage resource.

Transmission times, when scanning line wire size jump after, number counter automatic clear restarts the transmission for calculating new scanning line
Number.
The transmission times threshold value is the configuration information of scanning line, and before ultrasonic device work, i.e., configuration is in ultrasound
In equipment, and within the specific time, real-time calling can be carried out.
In the specific embodiment of the invention, if reading the transmission times of nth root scanning line and the default transmission of parsing acquisition
Frequency threshold value is identical, then judges to need to carry out the scanning of N+1 root scanning line after the completion of nth root scanning linear scan, at this point,
Due to the scanning stage in nth root scanning line, the corresponding configuration information of N+1 root scanning line is had been prepared for, i.e., has been cached RAM
The configuration information of the nth root scanning line stored in device is deleted, and matching for N+1 root scanning line is directly read from DDR memory device
Confidence, which is ceased and is sent in RAM buffer, to be cached, i.e., is i.e. by the N+1 of scanning by the configuration information update of nth root scanning line
The configuration information of root scanning line；And to i.e. by the corresponding configuration information pre-parsed of N+1 root scanning line of scanning, acquisition N+1
The configuration transmission times of root scanning line；Further, in the parameter configuration stage of N+1 root scanning line, the reading pair from caching
The configuration information of N+1 root scanning line is answered, and reads the corresponding transmission times of N+1 root scanning line, rejudges N+1 root
Whether the transmission times of scanning line is equal to its corresponding default transmission times threshold value.
If the transmission times of the current scanning line obtained is less than the transmission times threshold value that parsing obtains, then it represents that need to the
N root scanning line carries out repeating scanning, at this point, stopping processing N+1 root scanning line, repetition is read corresponding the N articles from caching and swept
The configuration information circular treatment nth root scanning line of the line inspection, until the transmission times of preceding nth root scanning line is equal to the hair that parsing obtains
Send frequency threshold value.
