scan vt. (-nn-) 1.細(xì)看,細(xì)察;審視。 2.〔口語〕大略一閱;瀏覽。 3.按韻節(jié)念,按句調(diào)讀,標(biāo)出(詩)的格律(指劃分音步)。 4.【電視】掃描;掃掠;搜索。 vi. 1.(詩)符合格律,讀起來抑揚(yáng)頓挫。 2.【無線電】掃描。 This line does not scan. 這一行不合韻律。 n. 1.細(xì)看;細(xì)察。 2.掃視,瀏覽。 3.【電視】掃描;掃掠。 4.眼界;視野。
The evahuation of x - ray , b - scan and ct in localization of foreign bodies in the wall of eyeball 對103例眼部異物進(jìn)行診斷及定位的臨床分析
A persistent shinning membrane of incomplete pvd and vitreomacular traction was found in indirect ophthalmoscopy and was confirmed by oct and b - scan ultrasonography 光學(xué)同步斷層掃描圖儀上的表現(xiàn)是明確的玻璃體黃斑部牽扯癥。
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 我們只要對這種疾病存有警覺性,并藉著詳盡的眼底檢查及超音波掃描,通常可有正確的診斷。
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超圖像處理子系統(tǒng)是高能超聲聚焦腫瘤治療系統(tǒng)的關(guān)鍵子系統(tǒng)之一,對它的研究直接關(guān)系到腫瘤治療系統(tǒng)的成敗。
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 本文圖像處理采用的總體方案是:首先,運(yùn)用圖像采集卡從b超儀獲取一系列超聲斷面圖像,然后對超聲圖像進(jìn)行去噪預(yù)處理,再通過人機(jī)交互的方式,手工勾畫出各層圖像中感興趣目標(biāo)的輪廓線,并運(yùn)用三維重構(gòu)技術(shù)進(jìn)行三維重構(gòu),最后運(yùn)用opengl將三維圖像顯示出來。
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 本文對超聲波原理、 b超成像原理、圖像采集技術(shù)、數(shù)字圖像處理技術(shù)、三維可視化技術(shù)等進(jìn)行了較為全面的研究,確定了圖像處理的總體方案,首先用matlab對要采用方法進(jìn)行仿真以驗(yàn)證可行性,然后進(jìn)行軟件編制和調(diào)試。
