便攜式B型超聲診斷儀具有無創(chuàng)傷、簡便易行、相對價廉等優(yōu)勢，在臨床中越來越得到廣泛的應(yīng)用。它將超聲波技術(shù)、微電子技術(shù)、計算機技術(shù)、機械設(shè)計與制造及生物醫(yī)學工程等技術(shù)融合在一起。開展該課題的研究對提高臨床診斷能力和促進我國醫(yī)療事業(yè)的發(fā)展具有重要的意義。 便攜式B型超聲診斷儀由人機交互系統(tǒng)、探頭、成像系統(tǒng)、顯示系統(tǒng)構(gòu)成。其基本工作過程是：首先人機交互系統(tǒng)接收到用戶通過鍵盤或鼠標發(fā)出的命令，然后成像系統(tǒng)根據(jù)命令控制探頭發(fā)射超聲波，并對回波信號處理、合成圖像，最后通過顯示系統(tǒng)完成圖像的顯示。 成像系統(tǒng)作為便攜式B型超聲診斷儀的核心對圖像質(zhì)量有決定性影響，但以前研制的便攜式B型超聲診斷儀的成像系統(tǒng)在三個方面存在不足：第一、采用的是單片機控制步進電機，控制精度不高，導(dǎo)致成像系統(tǒng)采樣不精確；第二、采用的數(shù)字掃描變換算法太粗糙，影響超聲圖像的分辨率；第三、它的CPU多采用的是51系列單片機，測量速度太慢，同時也不便于系統(tǒng)升級和擴展。 針對以上不足，提出了基于FPGA的B型超聲成像系統(tǒng)解決方案，采用Altera公司的EP2C5Q208C8芯片實現(xiàn)了步進電機步距角的細分，使電機旋轉(zhuǎn)更勻速，提高了采樣精度；提出并采用DSTI-ULA算法（Uniform Ladder Algorithm based on Double Sample and Trilinear Interotation）在FPGA內(nèi)實現(xiàn)數(shù)字掃描變換，提高了圖像分辨率；人機交互系統(tǒng)采用S3C2410-AL作為CPU，改善了測量速度和系統(tǒng)的擴展性。 通過對系統(tǒng)硬件電路的設(shè)計、制作，軟件的編寫、調(diào)試，結(jié)果表明，本文所設(shè)計的便攜式B型超聲成像系統(tǒng)圖像分辨率高、測量速度快、體積小、操作方便。本文所設(shè)計的便攜式B型超聲診斷儀可在野外作業(yè)和搶險（諸如地震、抗洪）中發(fā)揮作用，同時也可在鄉(xiāng)村診所中完成對相關(guān)疾病的診斷工作。

About: hamsterdb is a database engine written in ANSI C. It supports a B+Tree index structure, uses memory mapped I/O (if available), supports cursors, and can create in-memory databases. Release focus: Major feature enhancements Changes: This release comes with many changes and new features. It can manage multiple databases in one file. A new flag (HAM_LOCK_EXCLUSIVE) places an exclusive lock on the file. hamsterdb was ported to Windows CE, and the Solution file for Visual Studio 2005 now supports builds for x64. Several minor bugs were fixed, performance was improved, and small API changes occurred. Pre-built libraries for Windows (32-bit and 64-bit) are available for download. Author: cruppstahl
