Imaging medicine is the study of medical images. It encompasses medical imaging, radiation therapy, nuclear medicine, and basic imaging. The journal was founded by Future Medicine in 2009. It is a peer-reviewed, open-access publication. The journal is published quarterly. Readers can read the latest articles on medical imaging and related topics.
Noninvasive imaging techniques
Noninvasive imaging techniques in medicine have developed over the past century. Despite being relatively new, these techniques are becoming increasingly common in the medical field. They have greatly improved physicians’ ability to diagnose and treat heart disease. However, you should always seek a physician’s advice before undergoing any noninvasive imaging test. The results of the test will influence your doctor’s decision to proceed with treatment.
In addition to reducing patient discomfort, noninvasive imaging techniques can help the physician locate the lesions targeted during revascularisation or other adjunctive devices. By identifying the exact location of the lesions and assessing the arterial access site, these images can help to minimise the time and radiation associated with the procedure. Furthermore, they can help determine the degree of stenosis in arteries and assess thrombosis and other complications in the body.
Noninvasive imaging techniques can also be used to evaluate the condition of organs. One method uses a digital camera to detect molecular emissions. This type of imaging is ideal for repeated examinations, and is also effective in distinguishing between hard and soft tissues. In addition, multiple techniques are available, such as diffuse optical tomography (DOT), optical coherence tomography (OCT), and hyperspectral imaging (HIRS).
Molecular imaging
Molecular imaging is a new branch of imaging medicine that focuses on imaging molecules of medical interest inside living patients. It has many advantages, including the ability to diagnose many diseases in less time. It can also help improve the pre-clinical and clinical testing of new medications. Molecular imaging is an exciting new area of research, and it is expected to have a significant impact on medicine. Since the discovery of the human genome, research in molecular imaging has taken on a new direction.
Molecular imaging developed in radiology as a noninvasive way to understand the fundamental molecular processes within living organisms. Its development accelerated the development of many different imaging techniques. Today, the field is a rapidly growing area of research, allowing scientists to see disease in an entirely new way.
One of the most important applications for molecular imaging is oncology. Molecular imaging is becoming an important part of personalized medicine, which aims to diagnose patients based on their unique biological makeup. It is increasingly used to localize cancers and monitor their progress over time. However, there are some limitations to molecular imaging. First, it has to be noted that the radiopharmaceutical markers used in molecular imaging techniques vary. For example, FDG, which is commonly used as a ligand in PET-CT, has limitations. It is also not sensitive enough to identify many benign conditions.
Optical imaging
Optical imaging has many advantages over other imaging techniques, including lower costs and reduced exposure to harmful radiation. Unlike x-rays, optical imaging uses nonionizing radiation such as visible light and ultraviolet or infrared light. It can distinguish biological structures by their chemical composition and is particularly useful for monitoring disease and treatment. Optical imaging can also be used to measure metabolic changes, which are important early markers of disease.
Optical imaging is a noninvasive way to investigate tissue and organ function. This technology can be set up right at the bedside of a patient, and uses non-ionizing radiation to image organs and tissues. It can also detect microscopic structures and distinguish between native tissue labeled with probes. Optical imaging is becoming a common method for imaging in the medical field.
With the continued growth of medical technology, optical imaging will continue to be a staple in medical imaging. It will continue to have an impact on the field, especially in remote locations. The low-cost technology of optical imaging instruments is making a major difference in the field of medical imaging.
X-rays
X-rays are a commonly used method for imaging medical conditions. They are natural forms of electromagnetic radiation and are produced when charged particles strike a material with enough energy to cause radiation. While there is some concern about their potential effects on health, there are also a variety of medical uses for X-rays.
Most x-rays are safe for most people. However, people who are pregnant should avoid them unless absolutely necessary. The radiation from an x-ray may cause changes in developing fetal cells. These changes may increase the risk of birth defects and possibly cancer. The level of risk is dependent on gestational age and the amount of exposure to radiation. Additionally, pregnant women should avoid having an x-ray performed on the abdomen.
Before having an x-ray, a patient should inform their doctor of any allergies or medical conditions. Most health insurance policies cover medically-necessary X-rays, but they may have a co-pay or out-of-pocket expense. In some cases, a patient can call ahead to ask for a quote.
Computed tomography
Computed tomography (CT) is a diagnostic imaging procedure that produces detailed images of organs and structures inside the body. These images can be viewed on a computer monitor and printed on film or electronically. The images are often used to detect tumors. The images allow doctors to confirm the presence of a tumor and assess its size. They can also quickly and easily identify internal injuries and conditions.
The procedure usually takes a few minutes, but some scanners can image your entire body in as little as 30 seconds. CT images may also help doctors with biopsies. Before the procedure, metal objects should be removed, and you should not consume or drink anything for several hours before the scan.
Before undergoing a CT scan, discuss with your doctor whether it is the best option for your condition. It is important to note that CT scanners have weight limits that are set by manufacturers. The newer models can accommodate up to 220 kilograms of weight. However, the gantry used by CT scanners has a fixed diameter, which means that patients of a larger size are unlikely to fit through it. In such cases, the radiologist will discuss possible alternatives with you.
Fluoroscopy
Fluoroscopy is a diagnostic imaging procedure that is used to evaluate a patient’s health. It can be used as a stand-alone procedure or in combination with other medical tests. Before the procedure, patients should discuss their concerns and questions with the doctor. If possible, patients should write down their questions and concerns. They can also bring a trusted family member or friend to the preparation appointment to help them remember their concerns and take notes.
Today’s fluoroscopy systems feature high-quality images. The amount of radiation emitted per frame is relatively small, making it possible to use high-quality images with low radiation doses. However, since fluoroscopy involves several images, the total radiation dose is significant. This exposure level is greater than that of a simple x-ray examination, which typically uses only two or three images.
Fluoroscopy in imaging medicine is a type of diagnostic imaging that shows real-time movement of the body’s structures. The images are obtained by passing a high-energy X-ray beam through the body part to be studied and transmitted to a TV-like monitor. Fluoroscopy can be used to diagnose a variety of illnesses and to aid in other diagnostic or therapeutic procedures. It can also be used for surgical procedures.
Computer vision
Advances in computer vision have created a world where medical professionals can use computer-assisted image analysis to better diagnose and treat patients. By applying advanced algorithms, computer vision can help doctors recognize specific signs of illness and save them time. This technology has a great potential to improve healthcare, but it must be used appropriately.
CV can perform various tasks, from object detection and localisation to image segmentation and object recognition. Researchers have developed different methods to extract the features of images, including edges, corner points, and colour intensity. Among these methods, SIFT and SURF have gained much attention in the CV research community. These methods are invariant to image rotation, scaling, pose, and illumination. This makes them a key challenge for CV image analysis and training.
Computer vision has a range of applications in the healthcare field, with special applications in radiology and oncology. Potential uses include tracking the progression of tumors, detecting bone fractures, and searching for metastases in tissues. Computer-aided diagnosis is also being used to detect diseases like breast, lung, and prostate cancer, and improve overall quality of care.
