Hyperspectral imaging Essays

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

Ultrasound can be used as an alternative to x-ray for many investigations to minimize the use of radiation. The utility of ultrasound in the NICU lies in its portability, reliability and lack of radiation exposure. In NICU, ultrasound can be used for a wide range of indications, such as research, proceed guidance and rapid assessment of critical emergencies. In addition, ultrasound can be a guidance to improve safety and success rate of clinical procedures, such as umbilical vein catheter (UVC)

Most Common Barriers to Effective Communication with children, young people and adults can have a huge effect on relationships. Physical barries has to do with poor or outdated equipment used during communications, background noise, poor lighting, temperatures that are too hot or too cold. This can halt learning and pupils will become disengaged. Emotions like anger or sadness can taint objectivity. Also being extremely nervous, having a personal agenda or “needing to be right no matter what” can

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

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

Question 1 a) I work as a Principal Support and Business Analyst for NHS Wales Informatics Service (NWIS), where I am responsible for managing a team of six business analysts, who support and maintain the Welsh Radiology Information System (WRIS). NWIS is a Public Sector orgnaisation, responsible for providing Information Management and Information Technology (IT) services, and support to all NHS organisations within Wales. NWIS supports over seventy national services, including systems used in

Ultrasonography has been used in America for over forty years and is the most common diagnostic imaging method for obstetrics, but have ultrasounds ever been considered safe for use on patients? According to the FDA, ultrasonic imaging has an excellent safety record because it uses non-ionizing radiation. Therefore, it does not pose the same risks as X-rays or other imaging systems like nuclear medicine and computed tomography which use ionizing radiation (3). In spite of ultrasound’s shocking but

For the past 70 years, ultrasounds have been continually evolving with both diagnosis and treatment. An ultrasound is a type of diagnostic imaging technology. This technology uses sound waves to develop images based on the internal structures of the body. When the sound waves are being projected from a transmitter attached to the ultrasound and hits tissue, the sound waves reflect and create echoes which create a picture on the screen, the shorter the wavelength, the finer the detail of the picture

CT vs MRI vs X-Ray Introduction There are various imaging techniques x-ray technologist can perform help the doctor diagnose or treat patients. Choosing the most appropriate one will help in the recovery of the patient. Each technique comes with its advantages and disadvantages. Before the patient is given an order to have any one of them performed the doctor will evaluate the patient and their condition. Most patients know that radiation is not good for their bodies because studies show that people

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

determine the presence of abscesses, fistula and perforations in gastrointestinal system. Extra information can be obtained by Scintigraphic imaging about the progress of the disease. It screens the needs of further treatment or diagnostic procedure. Treatment monitoring, disease progress, other complications can be done by labelled white blood cell imaging. Both 111In and 99mTc can be used in label white blood cells. Single photon

Internal Imagers “Megan”, said Shanna holding a clip board with the patient’s information. As soon as the lady walked toward her, she admired the smiled that crossed the lady’s face, the joy her eyes had with her big belly in the way of her being able to walk right. Shanna was excited to see the patient once again with her husband because she knew they appreciated that she took care of what she was supposed to do, and let them know how their baby was doing. She took them to the room and checked

How long have you thought of a job for when you grow up? If you want to be a doctor who works with x-rays and medicine then a radiologist is the best position for you. Radiologist is a magnificent choice for people who want to be a doctor but also like to take x-rays/ pictures because of the work tasks you need to complete and the training and education you need to get to earn this position. The field radiology is in is the medical field. Radiology is in the medical field because some of the

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

Abdominal Ultrasound Imaging, Pelvic Ultrasound Imaging, Obstetric Ultrasound Imaging, Doppler Ultrasound Imaging, 3-D and 4-D Ultrasound Imaging, Echocardiograms, Carotid and Abdominal Aorta Ultrasound Imaging are all different types of ultrasounds. Abdominal Ultrasound Imaging is used to examine internal organs, including liver, gallbladder, spleen, pancreas, kidneys, and bladder. They show movement of internal tissues and organs and allow physicians to see the flow of blood. This ultrasound can

Diagnostic imaging is used every day all over the world and is growing rapidly. It is used in the hospital, OB/GYN offices, outpatient care centers, medical and diagnostic laboratories, and physicians’ offices (Cross, 2017). A diagnostic medical sonographer utilizes special equipment with sound waves to generate images. These images are used for assessing and diagnosing various medical conditions (Diagnostic, 2016). When most people hear the word sonography they think of pregnancy. Although, sonography

Ultrasound imaging is required in a plethora of situations. They allow physicians to have a more in-depth glimpse of what is going on inside of patients’ bodies, and can therefore permit them to act accordingly. Of course, it is given that technology with such profound capabilities must be quite convoluted. However, to simplify, in can be condensed in six simple procedures. First, the ultrasound machine conducts high frequency pulses into your body through a probe. These waves traverse into your

Although background information proves that ultrasound is a relatively safe and effective imaging tool there are still some complications during the procedure. Sonography is a safe and effective imaging tool, but the machines, “do not present this information in a manner that is easily accessed or understood by the operator” (Alexander 19). Ultrasound imaging can be difficult to understand because the procedure uses little to no radiation, for penetrating thick layers of human tissue can be difficult

What is a radiologic technologist? This was a question that I had when I first heard about the career. According to the Bureau of Labor Statistics (2015), “Radiologic technologists, also known as radiographers, perform diagnostic imaging examinations, such as x-rays, on patients.” This description became the first piece of knowledge that I received about radiologic technologists before doing more research and eventually applying for college to become one. As a student, there is a large amount of

Due to the ageing population more medical professionals are in demand to meet the needs of each individual, I believe that by studying a radiography course I can be part of the professionals who are making a difference in someone's life. Diagnostic and therapeutic radiography can transform a person’s life by getting the correct diagnosis and then treatment as quickly as possible to get the individual back on their feet. By becoming a radiographer I can be a part of the modern advancements in this
