**Coursera 课程总结：超声物理与仪器设备复习 (SPI/RMSK 考前准备)** 本课程为期 5.5 小时，旨在为准备 RDMS SPI 或 APCA RMSK 考试的学员提供超声物理和仪器设备的全面复习。课程包含约 15-20 分钟一次的理解检查，以及超过 100 道判断题和选择题，为实际考试提供充分的练习。 **课程内容涵盖：** * **超声基础：** 超声定义、基本性质和度量单位。 * **声波传播：** 声音的基本原理及其在软组织中的传播。 * **超声设备：** 超声设备及仪器组件和术语，换能器各部分及其功能。 * **成像原理：** 从发出的声脉冲到屏幕成像的全过程。 * **血流动力学与流体物理：** 基本的血流动力学和流体物理原理。 * **多普勒成像：** 彩色多普勒、脉冲波、连续波和能量多普勒的原理、优缺点。 * **成像伪影：** 各类成像伪影（如各向异性、伴影、边缘伴影、混叠等）的产生原因及特征。 * **安全与生物效应：** 超声安全以及热效应和机械效应。 * **其他超声模式：** 弹性成像、复合成像、组织谐波成像、斑点抑制、全景成像、色彩映射等。 **重要提示：** 本课程不符合 ARDMS SPI 考试的教育学分要求，仅作为额外的考前准备。
This course acts as a review of Ultrasound physics and instrumentation and is geared towards those preparing the the RDMS SPI or APCA RMSK exam. It would likely be useful for sonographers in other jurisdictions as well. The course is 5.5 hours of video with "understanding checks" every 15-20 minutes. As well as over 100 true-and-false and multiple choice questions in the Quizzes which should act as a good practice run for your exam. In the videos I'll cover:- the elementary principles of ultrasound including definition of ultrasound, basic properties, and units of measure.- Fundamental principles of sound and the propagation of sound in soft tissue.- components and terminology of ultrasound equipment and instrumentation. The parts of a transducer and their function. - The steps necessary to go from pulses of emitted sound, to creating an image on the screen.- Hemodynamics and some basic fluid physics.- Color Doppler, pulse wave, continuous, and Power doppler Imaging. How they work, their strengths and weaknesses.- Differentiate imaging artifacts by their cause and characteristic appearance: anisotropy, shadowing, edge shadowing, Aliasing, etc...- Outline safety and bioeffects (thermal and mechanical)- and other ultrasound features or modes: elastography, compound imaging, THI, speckle reduction, panoramic, chroma, etc...This course does not meet the ARDMS educational requirements to write the SPI exam. This course is additional preparation.
