Medical imaging Essays

Chapter 1 INTRODUCTION In medical science, imaging technology plays an important role in the diagnosis of the disease . It helps the doctor to see the interior part or portion of the body with ease which results in easy diagnosis i.e. doctor can make effective surgeries which is crucial for the diagnosis of disease and doctor can look inside easily without opening or closing too much part of the body. In the medical imaging there are different kind of alternates through which images are taken and

Each imaging modality is characterized primarily as being able to render high-resolution images with good contrast resolution (anatomic imaging) or to render images that depict tissue function (functional imaging). Anatomic (Structural) Imaging Imaging the structure of the body has been and continues to be the major application of medical imaging, although, as described in 9.2.2, functional imaging is a very active area of research. The goal of anatomic imaging is to accurately depict the structure

diagnostic based career will lead you to the exciting world of radiology. Radiology is the medical specialty devoted to imaging the inside of the human body without intrusion. Radiology is a type of medical imaging that doctors use to diagnose conditions such as broken bones and even tumors. Radiology technicians produce clear and accurate images of the body that enable physicians to diagnose and treat medical conditions.

scientific test that can prove a connection to a crime. The information obtained in any test must be admissible in a court of law. There are many branches of forensic sciences; one branch that is not well known is forensic radiography, or forensic imaging. “Conducting examinations that use ionizing radiation to gather and analyze forensic evidence constitutes forensic radiography” (ASRT. (2010).). Radiography uses ionizing radiation to capture images of bones and soft tissue. When these images are

Wilhelm Conrad Roentgen, and the first ever x-ray was actually of his wife's left hand on December 22, 1895. This machinery took off and is used all over the world by a Radiologic Technologist. A Radiologic technologist performs all types of medical imaging procedures, but most commonly x-rays. Radiologic technologists are also known as radiographers or x-ray techs. They provide a high standard of patient care, prepare patients for examinations, and explain procedures. Radiologic technologists have

Advancements in radiology have made a huge leap since the application was discovered. Over the decades, medical officials have used and created new machines or instruments to conduct more advanced procedures and experiments on patients. Although the first x-ray was invented in 1895, the first ever department of radiology was opened in July of 1954. Since it was first created, sonography has made a huge impact on patients, especially women. Ultrasound scans have come a long way in the world of radiology

Angiography is the most commonly used technique to visualize the blood vessels with particular interest in the arteries, veins, and the heart chambers. This is traditionally done by injecting a radio-opaque contrast agent into the blood vessel and imaging using X-ray based techniques such as fluoroscopy. The image of the blood vessel thus obtained is called an angiogram or angiograph. Depending on the type of angiogram, access to the blood vessels is gained most commonly through the femoral artery

blood cell and platelet. The radioactive agent commonly used to radiolabel the white blood cell include 99mTc -HMPAO and 111In-oxine. Technetium-99m is used in the blood or injected into patients systemic circulation so that it can be detected by medical equipment such as X-ray. Technetium exametazime under brand name of Ceretec which commonly perform radiolabel

Radiology is a tool frequently used in medicine. Almost everyone will have an X-ray, ultrasound, MRI, or one of any of the many other imaging techniques at some point. The use and development of various radiologic techniques have reduced the need of exploratory surgeries and given us a better idea of what is going on inside our bodies. Radiology as we know it today was was invented over a century ago by a German physicist and Professor named Wilhelm Conrad Roentgen 1. In 1895 he discovered electromagnetic

An AAS in Medical Radiography is one of the career paths that the Myers-Briggs and the Holland Code suggest that I pursue. I selected to investigate this field because I do have some experience with wor Scanning Electron Microscopy (SEM). With a Medical Radiograph degree the technician works with a Magnetic Resonance Imaging (MRI) machine. Working in the Medical field would be a drastic change for me. Medical Radiography is a degree that is offered by Gateway Community College (GCC). I believe

In the medical field, ultrasound played a significant role due to the fact that doctors can't see the patient’s organ failure without going through a surgery of opening the patient’s body. Ultrasound is one of the most safest and painless solution to this. Ultrasound imaging is known as sonography. It is known that ultrasound is a type of sound that is too high pitch for human to hear. It is approximately more than 20 000 Hertz. Ultrasound is the opposite of infrasound, which is a sound wave

A radiologic technician is a medical professional who utilizes specialized imaging equipment on patients. They operate equipment such as X-rays, sound waves, magnetic waves, and additional instruments of diagnostic imagery to create images of human anatomies, such as internal organs, bones, and tissues. This is critical to the medical industry because the scans the technicians acquire diagnose the patient and can be life-saving. I am profoundly interested in hopefully acquiring admission to the Southwest

One of the most useful biomedical diagnostic imaging tool is the computed tomography (CT) scan. CT scans allow for physicians to view cross sectional images of tissues and organs using x-ray and computer technology. Physicians are able to view all major body parts to look for abnormalities using a CT scan without having to take surgical biopsies or perform exploratory surgeries. These scans can be used to diagnose cancer, heart disease, locate blood clots, and determine if internal bleeding is

1. Write a brief introduction about the diagnostic imaging modality. Nuclear medicine is a section of medical imaging that uses radioactive medication known as radiotracers or radiopharmaceutical (Understanding nuclear medicine, 2009). Radiotracers are given to the patient through injection, swallowing or inhalation, which makes the body radioactive for a short time. The radiation is detected by a special camera, and then the image is produced. (Cain, 2013) NM is used to treat and diagnose diseases

facing new challenges each second of the day. Radiologists use medical imaging to look at the inside of people's bodies to diagnose them. “Radiologists are physicians who performs and interprets diagnostic imaging tests and interventional procedures or treatments that involve the use of X-ray, ultrasound, and magnetic resonance imaging equipment” (Tanja). They preform image-guided procedures, but they are not responsible for other medical needs of the patients being treated. They deal less with interaction

Neonatal Imaging of the Chest “Pediatric radiology has expanded rapidly since the late 1950s and is now a recognized medical specialty.” Page 577 of article. Obtaining successful images of a newborn can be quite a challenge. As stated in the article it takes 4 important aspect in taking a great image, “Technologist Attitude, Warmth, Immobilization, and Radiation Safety”. The newborns are not mind reader so they need to be comforted. The technologist attitude needs to have a smiling face and be

Physics of ultrasound Dr. Madhav Swaminathan, Dr. Aashish Jain Abstract: Medical practice of ultrasound is constantly expanding. It is now used for not only screening and diagnosis of various diseases, but also to enhance care in the field of anaesthesia and intensive care. Ultimately, the quality of care depends on imaging quality. Practitioners of ultrasound therefore need to understand the physics and principles behind the technology in order to create optimal images. In this article, we will

According to R.T. Dan L. Hobbs in his article in the Radiologic Technology Magazine, “the chest radiograph is the most common radiographic procedure performed in medical imaging departments, and one of the most often repeated exams.” The Fall and Winter months bring about, not only a change in our weather, but also bring about an increase in clinical visits from individuals afflicted with a variety of seasonal illnesses such as; influenza, upper respiratory infections, and pneumonia. It is the job

Using segmentation in medical images is a very important task for detecting [16] the abnormalities and tracking progress of diseases and surgery planning. Segmentation must not allow regions of the image to overlap. The main aim of medical image segmentation is to study anatomical structure, identify regions of interest, measures tissue volume to measure tumor growth. The main goal of literature survey is to present various image segmentation methods, to
