b a B picture 第二流影片。 A B student 成绩乙等的学生。 B battery 【无线电】 B 电池组。 B flat 【音乐】降 B 调〔记号 B〕。 B major [minor] 【音乐】 B 大调[小调]。 Not know B from bull's foot 见牛脚而不识B字;目不识丁;文盲〔英语字母B源于腓尼基象形文字“牛”。牛为偶蹄类,脚趾形似字母B。见牛趾而不识B字,喻文盲极其无知,故有此说〕。
The evahuation of x - ray , b - scan and ct in localization of foreign bodies in the wall of eyeball 对103例眼部异物进行诊断及定位的临床分析
A persistent shinning membrane of incomplete pvd and vitreomacular traction was found in indirect ophthalmoscopy and was confirmed by oct and b - scan ultrasonography 光学同步断层扫描图仪上的表现是明确的玻璃体黄斑部牵扯症。
The alert of the disease combined with careful examination of indirect ophthalmoscopy and the aid of b - scan ultrasonography will achieve the correct diagnosis of the disease 我们只要对这种疾病存有警觉性,并藉著详尽的眼底检查及超音波扫描,通常可有正确的诊断。
Ultrasound b - scan images processing subsystem is one of the key subsystem of the tumor therapy system with hifu , playing an important role in the development of the tumor therapy system with hifu B超图像处理子系统是高能超声聚焦肿瘤治疗系统的关键子系统之一,对它的研究直接关系到肿瘤治疗系统的成败。
The whole frame used in this paper is that , first , by using video card , we get a series of b - scan images , then delete the noise in this images . secondly , draw the outline of interesting object in each image by manual , through clicking mouse on screen . thirdly , reconstruct 3d - image using 2d contour 本文图像处理采用的总体方案是:首先,运用图像采集卡从b超仪获取一系列超声断面图像,然后对超声图像进行去噪预处理,再通过人机交互的方式,手工勾画出各层图像中感兴趣目标的轮廓线,并运用三维重构技术进行三维重构,最后运用opengl将三维图像显示出来。
In this paper , we study this aspects of ultrasonics , b - scan imaging , image collecting , digital image processing , and establish the whole frame of image processing . we first use matlab to simulate for its feasibility , then write programme and debug it 本文对超声波原理、 b超成像原理、图像采集技术、数字图像处理技术、三维可视化技术等进行了较为全面的研究,确定了图像处理的总体方案,首先用matlab对要采用方法进行仿真以验证可行性,然后进行软件编制和调试。
