Description: AT89S52单片机控制的超声波测距，主程序首先对系统环境初始化，设置定时器T0工作模式为16位的定时计数器模式，置位总中断允许位EA并给显示端口P0和P2清0。然后调用超声波发生子程序送出一个超声波脉冲，为避免超声波从发射器直接传送到接收器引起的直接波触发，需延迟0.1ms(这也就是测距器会有一个最小可测距离的原因)后，才打开外中断0接收返回的超声波信号。由于采用12MHz的晶振，机器周期为1us,当主程序检测到接收成功的标志位后，将计数器T0中的数（即超声波来回所用的时间）按下式计算即可测得被测物体与测距仪之间的距离,设计时取20℃时的声速为344 m/s则有：
d=(C*T0)/2 =172T0/10000cm（其中T0为计数器T0的计数值）
测出距离后结果将以十进制BCD码方式LED,然后再发超声波脉冲重复测量过程-AT89S52 MCU-controlled ultrasonic ranging, the main program first initializes the system environment, set the timer T0 mode for 16-bit timer counter mode, the set EA and the total Interrupt Enable bit ports P0 and P2 to show clear 0. Then send a subroutine call occurs ultrasonic ultrasonic pulses, in order to avoid direct transmission of ultrasound from the transmitter to the receiver caused by the direct-wave trigger, must delay 0.1ms (This is the range-finder will have a minimum measurable distance reasons) after the Only open the external interrupt 0 to receive the returned ultrasonic signals. As a result of 12MHz crystal, the machine cycle 1us, when the main program detects that received flag of success, will be the counter of the number of T0 (ie, used ultrasound back and forth time) determined by the formula and the measured object can be measured measured from the distance between the instrument, designed to take 20 ℃ when the speed of sound is 344 m/s there are:
d = (C* T0)

Description: 医疗数字图像处理基础
医疗数字图像、数字图像处理-There was a time not so long ago, well within the memory of many of us, when medical
imaging was an analog process in which X-rays, or reflected ultrasound signals,
exiting from a patient were intercepted by a detector, and their intensity depicted as
bright spots on a fluorescent screen or dark areas in a photographic film. The linkage
between the exiting radiation and the resulting image was direct, and the process of
forming the image was easily understandable and controllable.

Description: 为了提取血管扩张收缩的变化趋势，在采集原始视频AVI图像，进行帧序列转换后，提取血管轮廓成为研究
的重点。文中提出了一种基于标记分水岭对血管超声帧图像的分割方法，该法针对超声图像对比度低、噪声强的特点在标记
之前进行小波域增强。实验证明该法较传统的区域生长法更能准确地提取目标轮廓。基于该法得到的血管在连续时间内截面
积变化曲线，更方便医师进行精确的病理分析。由此可见，该法更适用于超声血管图像的边界提取。
-In order to extract the trend of contraction of vascular expansion, in the acquisition of the original video AVI images were converted frame sequence extracted from a focus of the study of vascular contours. In this paper, based on markers of vascular ultrasound frame watershed image segmentation method, the method for ultrasound image contrast is low, the characteristics of strong noise in the wavelet domain before marked increase. Experiments show that the method is more traditional region growing method to contour more accurately. The law is based on the blood vessels in the continuous-time cross-sectional area within the curve, more convenient and accurate pathological analysis of physicians. Thus, the method is more suitable for vascular ultrasound image boundary extraction.
