彩色信号

Television broadcasting,has many strengths.Examples are high image quality competitive to broadcast images, exible signal

世界广播电视技术从模拟信号向数字信号过渡，高标准的彩色监视器成为专业人士衡量、评判图像的依据。

The linear video signals applied in AC PDP are obtained from the conventional video signals after inverse gamma correction, which bring the loss of low gray images.

为了在彩色AC PDP中应用常规的视频信号，必须将常规的彩色视频信号进行反伽马校正使其转换成线性视频信号。

In particular, the method includes the luminance signal and the color difference signals being converted into color signals.

特别是，该方法包括将亮度信号和色差信号转换成彩色信号。

Because It take more time that copying the color graphics with software programmble on the color matrix printer , It is necessary that copying the color graphics with video signal of CRT.

由于用软件的方法在彩色点阵打印机上拷贝彩色画面费时费力，促使我们用硬件的视频信号来进行彩色画面的拷贝，实践证明效果较好。

The system makes use of the high-speed synchronous shoot and digital image processing technique to make the presswork figure redisplay stationary in the display apparatus.

本系统采用高速高精度的工业彩色CCD摄像机，在横向移动扫描装置和纵向扫描控制算法以及同步发生装置和同步瞬态采集方法的控制下，实时地摄取印刷品图像，并将视频信号输入到彩色图像采集卡。

Software system processes words by extracting the profile from the vector font and uses RGB mode to control the color signal.

软件系统通过提取矢量字体轮廓来处理文字信息，利用RGB方法控制彩色信号，预览和管理演示任务，并控制硬件设备完成激光演示。

Using CDFI to examine the models of TRAS were established before and after,observe the renal artery and each artery inside the TK, Emphasis to observe whetherthere are high speed color bloodstream signal in artificial TK arteriostenosis. Andachieve the pulse of artificial TK arteriostenosis、the renal artery and each arteryinside the TK, select the measure index include PSV、EDV and RI; Intravenous bolusinjection of contrast agent, Collect and store the continuous image which fromcontrast agent inner to disappear in TK and renal arterial. Open QLAB analysingsoftware, choose the region-of-interest, build TIC, measure and quantitativeanalysis on part parameter index.

在移植肾动脉狭窄动脉模型建立前后进行CDFI扫查，观察移植肾动脉及移植肾内各级动脉的彩色血流充盈情况，重点观察移植肾动脉人为狭窄处有无五彩镶嵌的高速彩色血流信号，并获取移植肾动脉人为狭窄处及肾动脉主干肾门处以及移植肾各级动脉的频谱，选取的测定指标包括：PSV、EDV、RI；经外周静脉注入造影剂，开启造影程序，采集并存贮造影剂开始注入至造影剂在移植肾动脉及移植肾内完全消失的连续动态声像图。

Results Masses were located at the branch of common carotid artery,so the interval between external and internal carotid arteries was enlarged.Low echoic substantial masses with clearly boundary were found.The bigger masses always grew around carotid arteries.More color flow signals were detected in the masses and most were arterial flow.

结果 颈动脉体瘤肿块位于颈总动脉分叉处，颈内及颈外动脉间距增宽，瘤体常呈实质性低回声，边界清晰，较大瘤体常围绕血管生长；彩色多普勒超声显示肿瘤内丰富彩色血流信号，以动脉血流为主，能显示瘤体与颈动脉的关系。

Methods:Baseline intramyocardial flows in left ventricular anterior wall in 15 normal subjects and in 14 patients with coronary artery diseasewere examined by CDCFI and pulse-wave Doppler.Then Albunex(0.08ml/kg)at bolus and after 15 min interval dipyridamole(0.56mg/kg)was injected within 4 mins respectively and intramyocardial flow in the anterior wall was observed sequentially.Results:In all normal subjects and 13 patients with CAD,color flow signals could be displayed scatteredly in the anterior wall.

应用冠脉血流显像技术检测15例正常人和14例冠脉造影证实为前降支中段和近段狭窄的冠心病患者前壁心肌内血流，显示清晰二维彩色多普勒信号后，应用脉冲多普勒探测血流频谱；分别在不同时刻经静脉注射Albunex 0.08ml/kg和潘生丁0.56mg/kg后，观察前壁心肌内彩色多普勒血流信号和频谱变化。

The tumors with ill defined border or with spiculated had higher axillary lymph node metastatic probabilities than tumors with clear outline.

病灶内彩色血流信号丰富程度与肿瘤的大小、腋窝淋巴结转移呈正相关，即：肿瘤越大，彩色血流分布越丰富，淋巴结转移几率越高。
