The specific embodiment
Fig. 1 is based on the actual implementation of DICOM all-direction M type electro cardiogram, and it 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.
Fig. 2 shows that manual mode is based on the DICOM all-direction M type electro cardiogram; Fig. 3 shows that automated manner is based on the DICOM all-direction M type electro cardiogram.
Automated manner: generally only adapt to minor axis cross section, chamber, heart B ultrasonic left side phase, at this moment the operator only need determine the center of circle, can form 12 omnirange line segments that scatter 30 ° at each interval from the center of circle automatically on the figure, and form the M type kinetocardiogram of 12 synchronous mutually direction line segment correspondences.
Manual mode: it is the artificially according to the direction of motion of detecting structure a part with mouse with the rubber band formula selected direction line segment that draws, and the ash point that searches per moment by it has formed the M type kinetocardiogram of this direction in conjunction with scanning.Owing to manually can determine a direction line segment from the arbitrary position of each structure of entire image, and each point should be regarded as and not have relative motion on the width of cloth two field picture, and so any a plurality of line of direction line segments have just generated can mutual synchronously comparable multi-direction M type kinetocardiogram.This mode is method in common, can comprise automated manner.
The present invention is novel, and is reasonable in design, and the kinetocardiogram of reflection is accurately clear, has bigger application value.
