Methods and results We assume the carotid arterial wall is the elastic material so we can use the Hooke's law to analyze it. The experiment is based on the use of ultrasound B-mode imaging technique and the off-line image analysis. Elastic tube phantom experiments demonstrated the validity of the technique, providing the size of the tube within 3% of the actual values. The system was also tested in the common carotid arteries of 10 healthy males (age 23.6 y). According to the experimental result, it shows that our index is less variant than Peterson's elastic modulus. The results of and are and respectively.

根据橡皮管的体外实验结果，利用超音波以及影像分析所得到的橡皮管尺寸，与实际尺寸间的误差只有3%，而使用超音波 B-mode 量测颈动脉的实验结果显示，在把颈动脉当作完全弹性体的假设下，所得到的 CIMT 硬度指标，於十位平均年龄为23.6岁的年轻健康男性中，结果与过去文献中常使用的 Peterson's elastic modulus 相比较，结果显示容易受到不同受试者间，不同的生理状态之影响，而在考虑受试者的 IMT 变化情况下，比能够反映更多的受试者颈动脉材料性质，因此得到了较为稳定的实验结果。

ET tube insertion procedures were performed on 59 pediatric patients aged newborn to 17 years (33 boys) due to cardiopulmonary arrest or impending respiratory failure. Ultrasound images were taken before and after the procedure in two-dimensional and time-sector modes using a portable ultrasonic machine. The subxiphoid window at the mid-upper abdominal — just beneath the xiphoid process and the lower margin of the liver — was used most often, with a wide transducer sector angle (90 degrees) for bilateral scanning of the diaphragm.

这项试验对59位从新生儿到17岁（33位男童）的小儿科病患进行插管，插管的原因是因为心肺衰竭或是严重的呼吸衰竭；在插管前与后使用可携带式超音波机器进行二度空间与时间象限的超音波显影；最常使用中上腹的剑突影像，就在剑突与肝脏下下缘部份的影像，与以宽的转换区间角度（90度）作横隔膜双侧扫描。

Therapeutic ultrasound has been used in the treatment of osteoarthritis for the relief of symptom and improvement of functional status. In recent study, we found that ultrasound enhances cartilage repair in experimental early stage osteoarthritis, and prevents deteriorative changes in later stages.

治疗性超音波已长久使用在关节炎治疗上以减轻关节炎症状并改善其功能，在最近的研究中我们发现超音波可促进大白鼠诱发性早期关节炎中关节软骨的修护，同时可阻止晚期关节炎中关节软骨的恶化。

The MR protocol involved transverse, coronal, and sagittal noncontiguous T2-weighted single-shot fast spin-echo sequences; transverse fat-suppressed T2-weighted fast SE sequences; transverse T1-weighted gradient-recalled-echo sequences; and transverse and coronal short inversion time inversion-recovery sequences performed through the lower abdomen and pelvis.

MR计划包括于下腹部与骨盆位置执行的，横轴的、冠状的、矢壮轴的非连续T2加权单射快速环绕音波程序；横轴压抑脂肪讯号的T2加权快速SE程序；横轴T1加权梯度回复音波程序；以及横轴、冠状短程反向时间反向回复程序；由2位放射科医师评估MR结果，以及与外科及病理发现、临床追踪数据比较。

Ultrasonographic study identified hypoechoic subdeltoid bursa and hypoechoic fluid surrounding the hyperechoic lesion, a possible conglomerate of urate, within the bulging acromioclavicular joint.

超音波检查显现低超音波性的三角肌下滑液囊和被低回音液体包围的高回音物质－可能是尿酸凝聚物－於肿胀的肩峰锁骨关节内。

Ultrasound and scintigraphy are non-invasive methods used to detect urinary extravasation. Reconstructed CT ureteropyelography has also been employed for the detection of urinary extravasation after renal transplantation. MRI imaging can show the renal function of the transplanted kidney and the extravasation. MRI is an effective non-invasive alternative for the diagnosis of urinary extravasation after renal transplantation especially when ultrasound and scintigraphy are inconclusive.

超音波及核子医学检查是诊断肾脏移植后尿液外漏的非侵袭性的方法，MRI 可以明确的侦测尿液外漏，而且可以知道移植的肾脏是否有功能，这能决定是否需要及是否值得再一次手术，所以MRI 是另一个可以有效且非侵袭性检查，在超音波及核子医学检查没有明确诊断时，可以帮助诊断。

Automatic boundary extraction of multiple targets of interest in an ultrasound image can not only help clinicians find out most perceptible objects, but also save sonologists' time for boundary delineation. Moreover, it is potentially helpful for the novice instruction and medical research.

中文摘要超音波影像之目标物自动边缘侦测，可帮助临床医师找寻可疑的目标物，节省检测人员手绘目标物的时间，还可以应用於超音波影像之电脑辅助诊断，新进医师的辅助教学，对於医疗诊断与教学研究都有帮助。

In addition, we use contrast sensitivity and contrast acuity as indicators of visual function and try to investigate: 1 the impact of aging on corneal and total ocular HOAs 2 the change of HOAs after the cataract surgery 3 to compare intraindividually the HOAs and functional vision between implantation of spherical and aspherical IOLs.

二、接受白内障超音波乳化术并人工水晶体植入的病人手术前后角膜及眼球整体高阶像差的变化。三、比较接受白内障超音波乳化术并植入传统球面人工水晶体，或新型态非球面人工水晶体术后高阶像差及视觉品质的不同；并分析其可能影响因子。

The cephalometric radiography and ultrasound image of swallowing were recorded just before and after anterior teeth retraction. All the changes and correlation between the variable of anterior teeth and the variable of tongue movement during swallowing were all discussed. The result showed that there was no significant change on duration and magnitude during swallowing after anterior retraction.

以13位符合条件的志愿者为受测对象，分别在前牙退后之前后各取一次测颅X光片及超音波吞咽之影像资料；而后以测颅X光片描绘取得前牙距离、角度的改变比率，另以电脑辅助分析超音波吞咽影像，得到舌头吞咽各分期的时间振幅之改变比率，再进行统计分析。

It was bad enough when conventional 2-D sonograms revealed unborn hearts beating and blurry hands waving, but the abortionists are absolutely aghast over rapidly spreading access to 3-D/4-D ultrasound technology.

传统的 2D 超音波照片可以显示胎儿的心跳与糢糊的挥手动作就已经够糟了，快速发展到 3D∕4D 的超音波技术，更是让堕胎的支持者瞠目结舌。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
