The utility model provides a DICOM based omni-directional M-mode echocardiography detection device in echocardiography comprising a DICOM standard image file analysis module, a DICOM synchronous time generator, a DICOM sequence image electrocardiograph extraction module, a conversion module utilized to convert DICOM sequence image data into original omni-directional M-mode sequence image data and an omni-directional M-mode echocardiography system, wherein the DICOM standard image file analysis module is connected to the following two modules: one module is sequentially connected to the DICOM synchronous time generator and the omni-directional M-mode echocardiography system; after the other module is connected to the conversion module utilized to convert the DICOM sequence image data into the original omni-directional M-mode sequence image data, one circuit is sequentially connected to the DICOM sequence image electrocardiograph extraction module and the omni-directional M-mode echocardiography system; the other circuit is connected to the omni-directional M-mode echocardiography system; the device allows more precise analysis of all structural movement of a heart and details of deformation.

Description

In the ultrasoundcardiogram based on the all-direction M type electro cardiogram checkout gear of DICOM

Technical field:

This utility model relates to a kind of Medical Instruments, particularly relates in the ultrasoundcardiogram all-direction M type electro cardiogram checkout gear based on DICOM.

Background technology:

Applicant's patent of invention " all-direction M type electro cardiogram method and system thereof the " (patent No.: 98125713.5; Publication number CN1225256A) is authorized at 2001.8.15, this system goes for all import color ultrasound equipment, in collecting the use of external color ultrasound data and equipment, we find the output of the relatively large DICOM of being furnished with of import color ultrasound (Digital Imaging andCommunications in Medicine) standard picture, its view data is exactly digitized, and more approach the initial data of equipment, so truer.Normal video output is based on by former all-direction M type electro cardiogram system, and though also promptly the original series view data how all to be transformed into PAL (25 frame/second) or certain stationary state of standard NTSC (30 frame/second) of standard.But practical situation when the phased angle of ultrasoundcardiogram sequence image be 90 °, the degree of depth can reach to 70-100 frame/about second the double reception system when the 15cm left and right sides.So view data is doubly lost by 3-4.Can retrieve the image information that 3-4 is doubly lost if can directly extract image in the color ultrasound equipment by the DICOM technology, the gray scale alignment of all-direction M type electro cardiogram be every frame sampling once; So the time shaft resolution of such all-direction M type electro cardiogram also doubly improved 3-4 from original 25/ second, the target that this is the analysis of M type kinetocardiogram, the research worker looked forward to, it makes the detail analysis of each structure motion of heart and distortion get more accurate.

View data owing to output here has been a digitized in addition, just needn't be to the collecting work of this image by image acquisition board.

Summary of the invention:

All-direction M type electro cardiogram checkout gear based on DICOM is provided to provide in a kind of ultrasoundcardiogram the purpose of this utility model, it can get the detail analysis of each structure motion of the heart in the view data that collects and distortion more accurate, and helps improving the speed of collection.

In this utility model ultrasoundcardiogram based on the all-direction M type electro cardiogram checkout gear of DICOM, it is characterized in that: it comprises that dicom standard image file analysis module, DICOM generator lock in time, DICOM sequence image electrocardio extraction module, DICOM sequential image data transfer the modular converter and the all-direction M type electro cardiogram system of sequential image data in the former Omnirange M type (MOV form) to, annexation between them is as follows, and dicom standard image file analysis module is connected to following two modules:

One, be connected to DICOM generator lock in time after, be connected to the all-direction M type electro cardiogram system;

Its two, be connected to the modular converter that the DICOM sequential image data transfers sequential image data in the former Omnirange M type (MOV form) to after, the one road is connected to DICOM sequence image electrocardio extraction module is connected to the all-direction M type electro cardiogram system; Another road is connected to the all-direction M type electro cardiogram system.

This utility model and former all-direction M type electro cardiogram relatively owing to the image that can directly extract by the DICOM technology in the color ultrasound equipment, can be retrieved the image information that 3-4 is doubly lost; The gray scale alignment of all-direction M type electro cardiogram be every frame sampling once, doubly improve so the time shaft resolution of such all-direction M type electro cardiogram will be able to 3-4 from original 25/ second, it makes the detail analysis of each structure motion of heart and distortion get more accurate; In addition, because the view data of output has been a digitized,, the speed and the degree of accuracy of gathering have further been improved here so needn't gather this image by image pick-up card.

Description of drawings:

The theory diagram that Fig. 1 this utility model is connected with peripheral data (wherein frame of broken lines is a theory diagram of the present utility model).

The specific embodiment:

This utility model comprises that dicom standard image file analysis module, DICOM generator lock in time, DICOM sequence image electrocardio extraction module, DICOM sequential image data transfer the modular converter and the all-direction M type electro cardiogram system of sequential image data in the former Omnirange M type (MOV form) to, annexation between them is as follows, and dicom standard image file analysis module is connected to following two modules:

This utility model is to convert the image file of DICOM to original system acceptable (mov form) back to operate by original system in former all-direction M type electro cardiogram system.Input information can carry ultrasoundcardiogram (the import color ultrasound especially in the recent period) equipment of DICOM, or its work station (image data base) or be stored in portable hard drive or other memorizeies in send dicom standard image file analysis module to, this module can be isolated each frame of digital image (containing electrocardio) data of sequence image, frame preface, frame per second, heart rate and the relevant required information of non-standard sequence motion image of rebuilding, and then enters sequential image data (MOV form) modular converter work in DICOM sequential image data → former Omnirange M type.Just become former all-direction M type electro cardiogram system's acceptable (MOV form) sequential image data by this module DICOM sequential image data.The appearance form of the electrocardiosignal that contains in this sequence image is different with original system, thus it detected by DICOM sequence image electrocardio extraction module, thereby extract and based on all synchronous electrocardiogram of DICOM all-direction M type electro cardiogram (ECG) signal.Because at this moment sequence image is not to be standard (PAL or NTSC) video signal as former all-direction M type electro cardiogram system, is that frame per second is not 25 frame/seconds or the 30 frame/seconds of fixed standard yet, but widely above such frame per second, and be change at random.So have among Fig. 1 from dicom standard image file analysis module, analyze the temporal information obtain DICOM (non-standard) generator lock in time that desynchronizes, the temporal information of generation replaces sequence image playback and the required temporal information of time sweep in the original system.
