具体地说根据心脏扩张末期采集的超声波数据来计算心脏扩张末期容量,根据心脏收缩末期采集的超声波数据来计算心脏收缩末期容量。 Specifically cardiac diastole is calculated according to the capacity of the heart end diastole ultrasonic data acquired is calculated based on ultrasonic data acquired cardiac systolic end systolic volume. 根据心脏扩张末期容量和心脏收缩末期容量之间的差得到喷血能力,释放量,每次心跳释放量,和容积变化图等,根据心肌的厚度可以估计出心肌的重量。 Obtain the difference between the end of heart dilation and cardiac systolic volume capacity spurting capability, emission, release each heart beat, the volume change and the like in FIG., The weight can be estimated according to the thickness of the myocardium in the myocardium.

检查人员需要在光标的某一新的位置(时间点)按下数据采样键,并根据检查人员自己对扩张期或收缩期数据采样时间的判断,采取其他键操作向装置发出指令。 Check need in a new position of the cursor (time) sample data key is pressed, and, based on their judgment of the person or systolic expansion data sampling time, take other gives an instruction to the key operation means. 对扩张期或收缩期的错误输入将产生错误的分析结果。 Erroneous input or systolic expansion will produce erroneous results.

因此,人们要求能够自动地识别扩张期或收缩期的数据采样时间点,以减少检查人员的键操作,并要求超声波诊断装置具有自动时间相位识别系统。 Thus, it is possible to automatically identify the data required sampling time points systole or diastole, the key operation to reduce the inspection personnel, and require the ultrasonic diagnostic apparatus having an automatic identification system time phase.

为了分析心脏功能(下面将解释),检查人员通过操作键盘150上的键可以沿时间轴移动光标。 For analysis of cardiac function (explained below), the examiner can move the cursor along the time axis by a key 150 on the keyboard.

图4A和4B表示了在屏幕上所显示的在某一时间点采样的B模式图像和生物信号的ECG波形。 Figures 4A and 4B show the ECG waveform and a B-mode image of a biological signal sampled at a certain time point is displayed on the screen. 为了分析心脏功能(下面将解释),检查人员通过操作键盘150上的键可以沿时间轴移动光标。 For analysis of cardiac function (explained below), the examiner can move the cursor along the time axis by a key 150 on the keyboard. 光标所指的时间的B模式图像将显示出来。 Time B-mode image of the cursor is displayed. 图4A和4B表示由光标位置所确定的不同的时间点处采样的B模式图像。 Figures 4A and 4B show the B-mode image at different points in time determined by the cursor position sampled.

设置屏幕上的时间量程使得在屏幕上出现至少两个ECG波形的R波,图3和图4的显示分别包含三个和两个R波,它可以观察包括扩张期和收缩期的心脏状态的一个完整周期以便对其进行分析。 Set the time on the screen range so that at least two R-wave appears on the ECG waveform screen, Figures 3 and 4 show, respectively, comprise three and two R-wave, which may be observed include cardiac systole and diastole state a complete cycle in order to analyze it.

在显示超声波图像和生物信号波形的情况下,检查人员可以在某一需要时间点通过操作键盘150使显示“冻结”,暂停对图像和波形的采样,并将该时间点的数据存储在摄影图像存储器141和生物信号存储器143中以便于以后的复查和分析。 In case of displaying the ultrasonic image and the biological signal waveform, the examiner may display a "frozen", suspend the sample images and the waveform at a point of time required by the operation of keyboard 150 causes, and the time point data stored in the photographed image review and analysis in memory 141 and memory 143 for biosignal later. 这时,检查人员可以移动光标观察另一个时间点。 In this case, the examiner can move the cursor to another time point was observed.

摄影图像存储器具有顺序地存储多重图像数据画面的能力,如100张以上的图像数据画面,该图像数据画面由信号处理部分120产生。 Photographic image memory having the ability to store multiple image data are sequentially screen, such as 100 or more image data of a picture, the picture image data generated by the signal processing section 120. 根据检查人员通过键盘150发出的冻结图像的指令,控制部分160暂停在摄影图像存储器中存储图像数据,检查人员转而进行以下的操作步骤。 Frozen image according to an instruction of the examiner emitted through the keyboard 150, the control section 160 pauses stores image data, a shift to the examiner the following steps in the photographic image memory.

检查人员操作键盘150上的向前/向后键将光标移到大约指示在扩张末期或收缩末期ECG波形的位置。 Examiner operates the forward / backward to move the cursor around on the keyboard 150 at a position indicated systole or diastole ECG waveform. 控制部分160响应从键盘150发出的指令信号,操作光标控制部分170按照指令在屏幕上对光标再定位。 The control section 160 in response to command signals from the keyboard 150, cursor control section 170 in accordance with the operating instructions on-screen cursor repositioning. 诊断数据处理部分140同样响应键盘150的光标移动指令信号,对新的光标位置上的心脏状态的时间相位进行识别,即,时间点是在收缩期或是在扩张期。 Diagnostic data processing section 140 in response to the same keyboard cursor movement command signal 150, the time of the state of the heart on the new position of the cursor to identify the phase, i.e., the time point is in systole or diastole.

具体地说,识别部分142根据以生物信号的R波为基准的预定时间区域识别光标所指的时间(图2中步骤S4),并如图3和图4A,4B的举例中所示,在光标附近用带有阴影线的小方块标记识别的结果(步骤S5)。 Specifically, the recognition section 1423 and 4A, for example according to time (step S4 in FIG. 2), and as the R-wave for a predetermined time as a reference biological signal recognition area indicated by the cursor. 4B, in result (step S5) with a small square near the cursor with the hatched mark recognition.

参考生物信号的峰值R波,可便于时间点的确定,并使得能够精确地识别时间相位。 Peak R-wave reference biosignal, may facilitate the determination of the point in time, and so that the time phase can be accurately identified. 它同时保证覆盖为了识别时间相位和分析心脏功能所包括的收缩期和扩张期的一个完整的状态周期。 It also covers a complete guarantee state periods of systole and diastole time phase in order to identify and analyze cardiac functions included.

对于在光标位置附近时间相位识别的结果,无论时间点是在收缩期或是在扩张期标记都显示在该光标附近。 The results for the cursor position at the time near the recognition phase, the time point is whether expansion or contraction of the mark are displayed near the cursor. 在图3和图4A,4B的举例中,显示位置用带有阴影线的小方块表示。 In the example in FIG. 3 and FIG. 4A, 4B, the display position indicated by small squares with hatched lines.

当检查人员在光标所指的检查时间点(收缩期或扩张期),通过键盘150发出分析指令时(步骤S6),从冻结时间T到光标位置t的一系列图像数据,即,Tt期间的图像数据从摄影图像存储器中读出并送到分析部分144。 When inspectors check at the time point (systolic or diastolic) under the cursor, the analysis command issued via the keyboard 150 (Step S6), T from the series of image data to the freezing time t of the cursor position, i.e., the period Tt of the the image data read out to the analyzing section 144 and the captured image memory.

具体地说,收缩期的超声波图像数据(如,在实线光标符号所指的时间点(a)处的图像数据)和代表识别部分142所识别的收缩期的标志首先被装进分析部分144。 Specifically, systole ultrasonic image data (e.g., image data at the time point of the solid line cursor symbol indicated at (a)) and a representative of the identified identification section 142 is first loaded into systole flag analyzing part 144 . 然后,随着检查人员光标移动的指令和分析的开始,扩张期的图像数据(如图3中的虚线光标符号所指的时间点(B)处的图像数据)和代表识别部分142所识别的扩张期的标志被装进分析部分144(图2中步骤S3-S7)。 Then, as the analysis start instruction and inspectors cursor movement, expansion of image data (time point cursor symbol dotted line indicated in FIG. 3 (image data B) at) representing the identified identification section 142 expansion of the flags are loaded into the analysis portion 144 (FIG. step 2 S3-S7).

识别部分142具有从50毫秒到ECG波形的R波的300毫秒处的预定时间范围(由图3中的A段表示),并作为假设收缩期的时间范围,和另一个从ECG波形的R波的300毫秒到下一个R波的50毫秒处的时间范围(由图3中的B段表示),并作为假设的扩张期的时间范围,因此,为检查人员在其指令的检查时间点对扩张期或收缩期做出判断。 Recognition section 142 at a predetermined time of 300 milliseconds from the R-wave having 50 ms to ECG waveform (indicated by section A in FIG. 3), and the time range is assumed as systolic, and the other R-wave from the ECG waveform 300 ms to time the next R-wave 50 milliseconds (indicated by section B in FIG. 3), and as the time range extension of the assumption, therefore, for the inspectors to expansion check time point of its instructions or systolic judgment.

根据所接收的收缩期和扩张期的图像数据和对心脏状态时间相位的识别结果,分析部分144通过计算这些数据的差值和变化率来对心脏功能进行分析(图2中步骤S8)。 The diastolic and systolic image data of the recognition result and the received state of the heart time phase, the analysis section 144 for analysis (step S8 in FIG. 2) on cardiac function and by calculating a difference between the rate of change of these data. 分析结果在显示设备190上显示,同时,经过数据总线(图中没有显示)将结果送到外部处理器或数据存储单元。 The results on the display device 190 displays, at the same time, via the data bus (not shown) the result to the external processor or data storage unit.

如上所述,按照本发明检查人员仅需要操作键盘150移动光标回溯摄影图像和发出开始分析的指令。 As described above, according to the present invention, the examiner only needs to operate the keyboard 150 to move the cursor back instruction photographic images and the generation start of the analysis.

结果,常规装置所需要的根据检查人员的判断做出的扩张期或收缩期的指令被自动时间相位识别过程所取代,因此,改进了检查装置的操作能力,并且,能够消除由人为的对周期的判断失误所造成的错误的分析结果。 As a result, the conventional apparatus needs to be replaced based on the determination made by the examiner or systolic expansion time phase instruction automatic recognition process, thus improving the operational capacity of the inspection apparatus, and can be eliminated by the artificial periodic erroneous analysis results caused by errors of judgment.
