Abstract

Disclosed are novel triggering technology for imaging and quantitatively analyzing tissues for sound palpation and a device. Electric physiological signals of cardiac cycles are obtained via a lead of a cardiogram or an echocardiogram, phonocardiogram and pulse cardiogram receptor, a trigger signal is selected when a cardiac cycle is in the same time phase according to the acquired physiological signals of cardiac cycles, sound pulse radiation is started and triggered by a sound palpation tissue imaging and quantitative analysis starting circuit which is connected with a color ultrasonic instrument, and analysis of hardness and fibrosis degree of the lever of a human body is realized by the aid of acoustic images. Accordingly, existing operation of manually starting a sound pulse radiation transmission button which is irrelevant to heart beat cycles is replaced, interference of heart beats to lever detection results is reduced, and high repeatability of examination results is achieved.

Description

The new triggering technique and the device of sound palpation imaging of tissue and quantitative analysis

Affiliated technical field

The present invention relates to a kind of medical ultrasonic image and organize the strain analysis technology, especially the improvement technology and the device of human liver's acoustic picture hardness and fibrosis analytical method.

Background technology

Organizing strain and elastogram and quantitative analysis is one of up-to-date iconography method of ultrasonic examination.Especially degree of hepatic fibrosis more there is its feature of organizing the increase of hardness numerical value, for clinical diagnosis hepatic fibrosis, liver cirrhosis and fatty liver provide important quantitative basis.All have similar hardness and the strain analysis function organized as Hitachi, Siemens, hundred victorys and latest model color ultrasound system of Toshiba.Especially Siemens ACUSONS2000 type color ultrasound has novel sound palpation imaging and tissue quantification (Vitual Touch Tissue Imaging and Quantification) measuring ability.In order to obtain testing result, advise patient to hold one's breath during detection and avoided the influence of respiratory movement, but testing result still obviously is subjected to the influence of heart contraction diastole campaign liver than high duplication.Because have when the Siemens ACUSON S2000 type color ultrasound of this function detects is to trigger the radiation of emission ping by manual buttons, the emission conduction of each ping radiation signal and heart collecting moving drive that liver moves the time mutually, the direction displacement is unfixing, to cause detecting area-of-interest hepatic tissue change in displacement inequality at every turn, each time and heart collecting moving cycle be uncorrelated manually triggers the radiation of emission ping testing result repeatability is reduced, just since cardiac cycle cardiac pollex not simultaneously the moving hepatic tissue of facies tract to different directions, the uncorrelated manual ping radiation that triggers emission of the motion of speed and cardiac cycle is met and testing result repeatability is reduced.It is dark more to be detected the position in addition, centrifugally dirtyly closely more is subjected to heart movement to influence die more can not to detect hepatic tissue character than the deep.

Summary of the invention

Make testing result repeatability reduce this problem in order to overcome the radiation of manual triggering ping, it is the benchmark reference of cardiac cycle with electrocardiogram or ultrasoundcardiogram, phonocardiogram, pulse pollex figure that this invention provides a kind of, and can set the radiating detection of the each ping of control all in cardiac cycle certain with new technique and device of triggering for the moment ping radiation emission mutually.

The new triggering technique and the device solves scheme of sound of the present invention palpation imaging of tissue and quantitative analysis are finished by following process: 1, obtain the electro-physiological signals of cardiac cycle and handle by the Electrocardiographic company of leading or ultrasoundcardiogram, phonocardiogram, the pulse figure sensor of beating.2, the cardiac cycle physiological signal with collection serves as to trigger with the triggering signal of telecommunication and the startup of phase for the moment with the cycle aroused in interest according to setting.3, sound palpation imaging of tissue and the quantitative analysis start-up circuit that the triggering signal of telecommunication of phase is connected in present color ultrasound instrument fixedly the time with the cycle aroused in interest starts to substitute existing manual buttons.4, start each ping radiation that this function just can make each triggering all same a period of time of cardiac cycle relative liver carry out palpation imaging of tissue and quantitative analysis detects.5, the new flip flop equipment of this palpation imaging of tissue and quantitative analysis can be built in the color ultrasound instrument circuit module, also can be by external connection.

The invention has the beneficial effects as follows, can reduce and the uncorrelated manual interference that triggers emission ping radiation factor to testing result of cardiac cycle, and the testing result of acquisition high duplication makes hepatic fibrosis and hardness obtain reliable quantitative Diagnosis easily.

Description of drawings

Below in conjunction with the description of drawings embodiments of the present invention.

Fig. 1 is a kind of flow chart of the present invention:

Labelling is represented among Fig. 1: 1. Electrocardiographic electrode and lead beat figure sensor and lead line of line or ultrasoundcardiogram, phonocardiogram, pulse, 2. electrocardiogram or ultrasoundcardiogram, phonocardiogram, pulse pollex figure signal of telecommunication process amplifier, 3. selected device is set when the triggering signal of cardiac cycle electro-physiological signals is launched mutually, 4. trigger ping radiation signal transmitter trigger device, 5. color ultrasound instrument sound palpation is organized the switch activated circuit of quantized triggering ping radiating electron.

The specific embodiment

Embodiment is referring to Fig. 1, the new triggering technique of sound palpation imaging of tissue and quantitative analysis and device adopt Electrocardiographic electrode and lead line or ultrasoundcardiogram, phonocardiogram, beat figure sensor and lead line 1 and obtain the electro-physiological signals of cardiac cycle and be connected electrocardiogram or ultrasoundcardiogram of pulse, phonocardiogram, on the pulse pollex figure signal of telecommunication process amplifier 2 signal is carried out processing and amplifying, selected device 3 phase trigger point when selected is set during again by the emission of the triggering signal of cardiac cycle electro-physiological signals mutually, this the time phase trigger point can be as required, certain that chooses at random cardiac cycle is the moment of phase for the moment, especially in diastole static relatively moment in late period.The triggering signal emission time is provided with the triggering signal (so that obtaining meansigma methods) of phase moment in same a period of time of selected device 3 optional orders or several cardiac cycles mutually, starts color ultrasound instrument sound palpation and organizes the switch activated circuit 5 emission ping radiation of quantized triggering ping radiating electron that liver is detected by triggering ping radiation signal transmitter trigger device 4.When liver being carried out palpation imaging of tissue and quantitative analysis detection with ultrasonic probe, phase trigger point when the selected cardiac cycle of selected device 3 is set when using the triggering signal emission of cardiac cycle electro-physiological signals mutually, start triggering signal transmitter trigger device 4 by the operator, launch the ping radiation with this with alternative existing triggering of the related startup triggering of cardiac cycle with the uncorrelated manual mode operation startup of cardiac cycle, guaranteed that each detects the same a period of time phase moment emission of triggering ping radiation at each cardiac cycle, has reached the high duplication of check result.Owing to reduced the interference of heart collecting moving, detected zone also can be further near heart in order to detect liver deep pathological changes.
