| 5. | Then , in m - mode processing part , an algorithm for synthesizing the m images was proposed and the images were processed correspondingly
M型图像处理部分主要是提出了一种m型合成的算法，并在此基础上作一些相关处理。 |
| 6. | Shutter speed from 112 , 000 to 30 sec . manually selectable in 12 ev or 13 ev increments , aperture set by autoexposure program manual exposure ( m - mode )
可以在112 , 000秒至30秒的快门速度范围内手动选择快门速度，每次以12ev或13ev增减；自动曝光程式会自动设定光圈值 |
| 7. | M - mode is often used to examine the heart , for example measuring the diameter of vascular , examining the valve , etc . so m - mode is an important aid to the doctor in examining the heart
M型常用于心脏运动的探查，如对心血管各部分大小的测量，厚度的测量，瓣膜运动情况的测量等，是医生对心脏进行检查的一个重要依据。 |
| 8. | Finally , a software package developed by the author was introduced . in this software , we realized the functions of image playing via multimedia , image processing , m - mode image synthesizing , measurement of organ parameters , and so on
论文最后部分介绍了论文工作中自行编写的一套图像处理软件，该软件实现了多媒体的播放、图像增强、边缘检测、 m型的合成、图像的测量以及文件的管理等。 |
| 9. | Ultrasonic bio - instrumentation has several display modes used in medicinal field now , such as b - mode and m - mode , etc . b - mode uses the modulated brightness to represent the amplitudes of ultrasonic echoes , and the coordinates in the formed profiles correspond to positions of ultrasonic beam scans one by one
B型显示是用亮度调制来显示回波脉冲幅度，显示的横轴和纵轴与声束扫描的位置一一对应，形成超声切面图像。 |
| 10. | M - mode is a kind of dynamic display mode . it also uses the brightness to represent the strength of the ultrasonic returns , but the independent variable in the display is time . returns from different scanned depths are revealed along the time axis to show the movement of different layers of the scanned organs
M型是一种运动显示方式，它也是以亮度的强弱来表示回声信号强弱，但将声束路径上不同深度的回波图象沿时间轴慢慢展开，以表示界面的运动轨迹。 |
