Below be two embodiment that realize the concrete monitoring arrangement of said method.
Embodiment one.
Shown in Fig. 2,3,4.
The real time ultrasound monitoring device in gynae treatment of ultrasonic imaging method before a kind of the utilization, as shown in Figure 2, it mainly by two ultrasonic generation receiving systems 1,2 (as B ultrasonic), two with as described in the output of ultrasonic generation receiving system display device 3 and two ultrasonic probes 4,5 of linking to each other form, as shown in Figure 2; Described ultrasonic probe 4,5 is respectively trans-abdominal ultrasound probe and Transvaginal Ultrasound probe, the trans-abdominal ultrasound probe all links to each other with ultrasonic generating means 1,2 by time schedule controller 6 (as shown in Figure 2) with the Transvaginal Ultrasound probe, the ultrasonic reflection signal that is scanned object is obtained in their alternations under the control of this time schedule controller 6, this ultrasonic reflection signal is delivered to display device 3 real-time display images after ultrasonic generating means is listened central controller and DSC cell processing, display device 3 can be a display, also can be the display of two platform independent.The operation principle of time schedule controller 6 such as Fig. 3, it can adopt the sequence circuit on existing conventional textbook or the e-magazine to be realized, also can adopt single-chip microcomputer shown in Figure 4 to add the mode of controlling software is realized, be that described time schedule controller both can be tangible controller, also can be virtual controller, for the electrical technology personnel, contrast Fig. 3,4 can realize easily, U1, U2 are single-chip microcomputer commonly used in two B ultrasonic control circuits among Fig. 4.
When the quantity of described ultrasonic generation receiving system is two, they link to each other with trans-abdominal ultrasound probe, Transvaginal Ultrasound probe and display device by time schedule controller, and this time schedule controller is made up of main frame sign I/O control circuit, frame synchronization I/O control circuit, duty I/O control circuit.
The general employing of described trans-abdominal ultrasound probe frequency is the low-frequency probe of 3.5MHz, and the Transvaginal Ultrasound probe is the high frequency probe of 6.5MHz.
Described display device can be made up of a display, at two width of cloth images of ultrasonic signal after ultrasonic generating means conversion that show simultaneously on the same screen on this display that corresponding ultrasonic probe obtains, display device also can be made up of two display, and two display show the image of ultrasonic signal after ultrasonic generating means conversion that corresponding ultrasonic probe obtains respectively.
Monitoring arrangement of the present invention is by 2 ordinary ultrasonography bs, through transforming, forms (certainly, this just for convenience fully can be around this principle, and design realizes this systemic-function in a B ultrasonic, sees embodiment two for details) after installing Synchronization Control additional.Install the purpose of Synchronization Control additional, be in order to prevent that the probe ultrasonic waves transmitted from fully not decayed by human body and received imaging by another probe, this is for another probe, and this ultrasound wave is exactly an interfering signal, and this interference meeting is very strong, hinders normal pictorial display.
Core of the present invention is two identical or different probes two different tomographies of scanning and demonstration in real time simultaneously simultaneously.Its core technology, just this synchronous control technique, by this technology, reached two B ultrasonic collaborative work, do not disturb mutually, observe simultaneously the ultrasound tomographic image of two different tangent planes in real time, can strengthen accuracy, the reliability of clinical diagnosis greatly.
The purpose of Synchronization Control, briefly, in the time of will allowing the low-frequency probe emission receive a two field picture exactly (this is for convenience, also can not be a frame, and specific design is corresponding to be changed to some extent, but principle is identical), high frequency probe stops emission and receives; And high frequency probe is launched when receiving a two field picture, and low-frequency probe stops emission and receives.Image is separately gathered in " table tennis " formula ground alternation like this, two probes separately, does not disturb mutually.Just owing to, half the time is arranged in wait for every B ultrasonic, can not images acquired, so the frame per second of ultrasonoscopy can drop by half.But because the frame per second of modern B ultrasonic can be at 15-30 frame/between second, add the internal organs that the majority of being detected is a microinching, so still there is very high clinical value in this system.
The operation principle of Synchronization Control can utilize three pairs of control signals wherein to realize as shown in Figure 3, and the interface by special use links to each other two B ultrasonic with cable.Wherein, two relations through the B ultrasonic transformed are reciprocity, can be main frame or slave, but during scanning simultaneously, can only have one to be main frame, and this is determined by arbitrated logic.
Certainly, this implementation is not unique, for convenience, only is introduced with regard to this mode below.
Introduce this 3 pairs of control signals below respectively:
1, main frame sign input/output signal
This to signal deciding during scanning simultaneously, which platform machine is a main frame, which platform machine is a slave.
The duty of main frame decision slave, and slave can only be accepted the duty that main frame is arranged passively; But this relation is not fixed, when main frame stops scanning, will relinquish host status, and slave becomes main frame, till it stops scanning.
Suppose two machines from the off-mode to the start, and will begin scanning that the machine that then begins scanning earlier just is main frame; The situation that two machines are competed main frame simultaneously is easy to eliminating in operation, also can further improve in software and hardware and be got rid of.
When main frame stopped scanning, slave became main frame, till it stops scanning.
When certain machine was main frame, its main frame sign output signal was effectively, otherwise is invalid; The main frame sign output signal of slave is invalid always
2, frame synchronization input/output signal
The beat that ultrasound frames scanned when this was used for the scanning simultaneously of synchronous two machines to signal, slave always according to the beat work of main frame output, be synchronized with main frame, but slave is scanning or stops at current beat,, be exactly the duty output signal of main frame then by next signal controlling.
3, duty input/output signal
This is during to the scanning simultaneously of two machines of signal deciding, any platform scanning present frame, and which platform stops scanning, and this is determined by main frame.We can define the duty output signal of main frame when invalid, main frame scanning present frame, and slave stops scanning; And the duty output signal of main frame is when effective, slave scanning present frame, and main frame stops scanning.Like this, just accomplished without any confusion collaborative work.
Above-mentioned realization principle is basic, can also can design many different embodiments as the case may be during concrete enforcement, but change ten thousand times without leaving the original aim or stand, be exactly the cycle alternation of principal and subordinate's machine, thereby obtain the ultrasonic cross section picture of two two different aspects, identical or different probe scannings.
Can will be used for fixing in patients abdomen during use, by abdominal part a ultrasonic tangent plane (as the cross section) be carried out at the patient position and monitor through the abdominal part probe.The Transvaginal Ultrasound probe is inserted patient's intravaginal by vagina, especially can place uterus neck or posterior fornix position (it is relative with the shape of posterior fornix identical to pop one's head in), provide another tangent plane (as longitudinal section) inspection at patient position to monitor.
Through abdominal part probe and transvaginal probe emission/received ultrasonic signal is that timesharing is carried out.A probe is in work, and the another probe can not cause interference, just as not existing.It is to utilize electrical switch to carry out high speed to switch that probe switches.
Main frame shows the ultrasonoscopy of two probes simultaneously in real time.
This is the shortcoming that has overcome existing apparatus, makes the position of Type B ultrasonic monitoring instrument probe enter comparatively ideal position and is convenient to operation.Can be used for the real-time ultrasound guiding of intrauterine, cervix uteri and fallopian tube surgical operation and non-surgery operation operation (comprising uses such as physical examination) and the device that monitors.
Below be a concrete use:
The patient gets calculi position, and this device main frame places the patient left side, and a 3.5MHzR60 probe crosswise fixed is in patient's abdominal part, and a 6.5MHzR10 probe places the arched roof position of patient's vagina, and display is fixed on patient's abdominal part top by the linking arm of main frame.
Show the scanning image of two probes on the display, one of them has shown the cross section in uterus, and another has shown the longitudinal section in uterus.
The timesharing emission control process of main frame is: for the 3.5MHz probe, detection range is about 200mm, and an acoustic beam line needs about 270 μ s, and a frame scanning needs 35ms with 128 line computations; For the 6.5MHz probe, detection range is about 70mm, and an acoustic beam line needs about 90 μ s, and a frame scanning needs 12ms with 128 line computations; Like this, two probes are respectively finished the frame scan 47ms that takes time altogether, the refresh cycle of the scanning image of two probes on the display was about for 20 frame/seconds, have so just realized simultaneously the realtime imaging to two probes.
Embodiment two.
As shown in Figure 5.
The difference of present embodiment and embodiment one is that described ultrasonic generation receiving system adopts the pattern of two probes of a B ultrasonic band, and its time schedule controller will be more simple, can adopt a single-chip microcomputer to add software and be realized.All the other do not relate to the part all with have technology identical.
Part that the present invention does not relate to all can adopt prior art to be realized.
