杨绛先生:翻译的技巧
要把西方语文翻成通顺的汉语,就得翻个大跟头才颠倒得过来 汉语和西方语言同样是从第一句开始,一句接一句,一段接一段 ,直到结尾;不同主要在句子内部的结构。西方语言多复句,可 以很长;汉文多单句,往往很短。即使原文是简短的单句,译文 也不能死挨着原文一字字的次序来翻,这已是常识了。所以翻译 得把原文的句子作为单位,一句挨一句翻。

医学影像学的英文

医学影像学的英文Medical Imaging in EnglishMedical imaging refers to the techniques and processes used to create images of the human body for clinical purposes. It plays a crucial role in the diagnosis and treatment of various medical conditions. In this article, we will explore the field of medical imaging and discuss its importance in the healthcare industry.One of the most common modalities used in medical imaging is X-ray imaging. X-rays are a form of electromagnetic radiation that can pass through the body, allowing healthcare professionals to visualize internal structures such as bones and organs. X-ray images are particularly useful in the diagnosis of fractures, lung conditions, and gastrointestinal issues.Another important modality in medical imaging is computed tomography (CT) scanning. CT scans use a combination of X-rays and computer technology to create cross-sectional images of the body. This allows for detailed examination of internal organs and tissues, making it an invaluable tool in the detection of tumors, infections, and other medical abnormalities.Magnetic resonance imaging (MRI) is another widely used modality in medical imaging. MRI uses magnetic fields and radio waves to generate detailed images of the body's internal structures. MRI is particularly useful in imaging soft tissues such as the brain, spinal cord, and muscles. It is often used to diagnose neurological disorders, joint injuries, and tumors.Ultrasound imaging, also known as sonography, uses sound waves to create images of the body's internal structures. Ultrasound is commonly used to visualize the fetus during pregnancy, as well as to assess the health of organs such as the heart, liver, and kidneys. Ultrasound is a safe and non-invasive imaging modality that is widely used in medical practice.Nuclear medicine is a specialized branch of medical imaging that uses radioactive substances to visualize and diagnose medical conditions. Techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT) are commonly used in nuclear medicine to detect diseases such as cancer, heart conditions, and neurological disorders.In addition to these modalities, medical imaging also encompasses a variety of other techniques such as fluoroscopy, mammography, and angiography. Each modality has its own strengths and limitations, and healthcare professionals must choose the most appropriate imaging technique based on the patient's condition and the clinical question at hand.The field of medical imaging is constantly evolving, with new technologies and techniques being developed to improve diagnostic accuracy and patient outcomes. Artificial intelligence (AI) and machine learning are increasingly being used in medical imaging to analyze images, detect abnormalities, and assist in diagnosis. These advances hold great promise for the future of medical imaging and have the potential to revolutionize healthcare delivery.In conclusion, medical imaging is an essential component of modern healthcare, providing healthcare professionals with valuable information todiagnose and treat medical conditions. From X-rays to MRI to nuclear medicine, the field of medical imaging offers a wide range of modalities to visualize the human body and provide insights into the underlying pathology. As technology continues to advance, the role of medical imaging in healthcare will only continue to grow in importance.。
医学影像学专业英语X-RAY IMAGING

X-RAY IMAGING
DIGITAL SUBTRACTION IMAGING
Digital subtraction imaging (DSI) is a process whereby a computer removes unwanted information from a radiographic image. It is particularly useful for angiography, referred to as DSA.
X-RAY IMAGING
After an X-ray exposure is made the films are processed in a darkroom or more commonly in free-standing daylight processors. The resulting image is commonly known as an ‘X-ray’. The common terms ‘chest X-ray’ and ‘abdomen Xray’ are widely accepted and commonly abbreviated to CXR and AXR, respectively. More correct terms for an X-ray image are ‘radiograph’ or ‘plain film’.
X-RAY IMAGING
Consolidated lung lying against the heart border will therefore obscure that border. A good example is consolidation or collapse of the right middle lobe causing loss of definition of the right heart boder. These comments apply to all radiographically visible anatomical interfaces in the body.
