MEDICAL SCANNERS

Medical scanner is also known as Medical Imaging. Medical Imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities. Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical imaging.

As a discipline and in its widest sense, it is part of biological imaging and incorporates radiology, which uses the imaging technologies of:

• X-ray radiography
• Magnetic resonance imaging
• Ultrasound
• Endoscopy
• Elastography
• Tactile imaging
• Thermography
• Medical photography
• Nuclear medicine functional imaging techniques as
• Positron emission tomography (PET)
• Single-photon emission computed tomography (SPECT)

Measurement and recording techniques that are not primarily designed to produce images, such as electroencephalography (EEG), magnetoencephalography (MEG), electrocardiography (ECG), and others, represent other technologies that produce data susceptible to representation as a parameter graph versus time or maps that contain data about the measurement locations. In a limited comparison, these technologies can be considered forms of medical imaging in another discipline.

Medical imaging is often perceived to designate the set of techniques that noninvasively produce images of the internal aspect of the body. In this restricted sense, medical imaging can be seen as the solution of mathematical inverse problems. This means that cause (the properties of living tissue) is inferred from effect (the observed signal).

TYPES OF MEDICAL SCANNERS/ IMAGINING

There are many different types of medical scans, some of which are listed below

• RADIOGRAPHY

Two forms of radiographic images are in use in medical imaging. Projection radiography and fluoroscopy, with the latter being useful for catheter guidance. These 2D techniques are still in wide use despite the advance of 3D tomography due to the low cost, high resolution, and depending on the application, lower radiation dosages with 2D technique. This imaging modality utilizes a wide beam of x-rays for image acquisition and is the first imaging technique available in modern medicine. 

• MAGNETIC RESONANCE IMAGING

A magnetic resonance imaging instrument (MRI scanner), or “nuclear magnetic resonance (NMR) imaging” scanner as it was originally known, uses powerful magnets to polarize and excite hydrogen nuclei (i.e., single protons) of water molecules in human tissue, producing a detectable signal which is spatially encoded, resulting in images of the body.

• NUCLEAR MEDICINE

Nuclear medicine encompasses both diagnostic imaging and treatment of disease, and may also be referred to as molecular medicine or molecular imaging and therapeutics. Nuclear medicine uses certain properties of isotopes and the energetic particles emitted from radioactive material to diagnose or treat various pathologies. Different from the typical concept of anatomic radiology, nuclear medicine enables assessment of physiology. Medical Scanner Rovich Diagnostic

• MEDICAL ULTRASOUND

Medical ultrasound uses high frequency broadband sound waves in the megahertz range that are reflected by tissue to varying degrees to produce (up to 3D) images. This is commonly associated with imaging the fetus in pregnant women. Uses of ultrasound are much broader, however. Other important uses include imaging the abdominal organs, heart, breast, muscles, tendons, arteries and veins.

• ELASTOGRAPHY 

Elastography is a relatively new imaging modality that maps the elastic properties of soft tissue. This modality emerged in the last two decades. Elastography is useful in medical diagnoses, as elasticity can discern healthy from unhealthy tissue for specific organs/growths. For example, cancerous tumors will often be harder than the surrounding tissue, and diseased livers are stiffer than healthy ones. There are several elastographic techniques based on the use of ultrasound, magnetic resonance imaging and tactile imaging. The wide clinical use of ultrasound elastography is a result of the implementation of technology in clinical ultrasound machines. Main branches of ultrasound elastography include Quasi Static Elastography/Strain Imaging, Shear Wave Elasticity Imaging (SWEI), Acoustic Radiation Force Impulse imaging (ARFI), Supersonic Shear Imaging (SSI), and Transient Elastography.

• PHOTOACOUSTIC IMAGING

Photoacoustic imaging is a recently developed hybrid biomedical imaging modality based on the photoacoustic effect. It combines the advantages of optical absorption contrast with an ultrasonic spatial resolution for deep imaging in (optical) diffusive or quasi-diffusive regime. Recent studies have shown that photoacoustic imaging can be used in vivo for tumor angiogenesis monitoring, blood oxygenation mapping, functional brain imaging, and skin melanoma detection, etc.

• TOMOGRAPHY 

Tomography is the imaging by sections or sectioning. The main such methods in medical imaging are: X-ray computed tomography (CT), or Computed Axial Tomography (CAT) scan, is a helical tomography technique (latest generation), which traditionally produces a 2D image of the structures in a thin section of the body. In CT, a beam of X-rays spins around an object being examined and is picked up by sensitive radiation detectors after having penetrated the object from multiple angles.

• ECHOCARDIOGRAPHY

When ultrasound is used to image the heart it is referred to as an echocardiogram. Echocardiography allows detailed structures of the heart, including chamber size, heart function, the valves of the heart, as well as the pericardium (the sac around the heart) to be seen. Echocardiography uses 2D, 3D, and Doppler imaging to create pictures of the heart and visualize the blood flowing through each of the four heart valves. Echocardiography is widely used in an array of patients ranging from those experiencing symptoms, such as shortness of breath or chest pain, to those undergoing cancer treatments. Transthoracic ultrasound has been proven to be safe for patients of all ages, from infants to the elderly, without risk of harmful side effects or radiation, differentiating it from other imaging modalities.

IMPORTANCE OF MEDICAL SCANNERS

Medical imaging is an extremely important element in medical practice in this day and age. Medical imaging has changed the face of the healthcare industry and allowed practitioners and scientists to learn more about the human body than ever before.

• The use of ultrasound imaging is extremely important for expectant mothers. Ultrasound technology has advanced significantly over the past decade, and sonogram images are now produced with a much higher resolution, creating finely detailed images. This gives obstetricians a vastly improved picture of the baby’s health and progress in the womb, allowing them to ascertain any issues of concern much earlier on in the pregnancy. As well as obstetrics, ultrasound is extensively used on other parts of the body including the soft tissues of the neck, breasts, abdomen, pelvis, and soft tissues of the extremities. It is also used as a guide for biopsies of soft tissues and for some treatments.
• Medical imaging also is used by surgeons as an aid in surgical procedures. One example of medical imaging as an effective surgical tool is in the case of endoscopic sinus surgery. The extensive network of the sinus can be examined closely prior to the procedure through study of a CT scan. CT scans can provide 3D images of various cross-sections of the body–images which are of absolute necessity when preparing to operate on such an area. 
• Medical imaging is truly a vital element of the healthcare world–an essential tool for physicians to assist with diagnostics, treatment, and prevention. As technology continues to advance at a rapid rate, we will see growth in medical imaging technology as well. With scientific advancement and a continued effective use, medical imaging will continue to help with earlier detection of health issues, aid in easier treatment, and provide increased preventative care.
•  Medical imaging can also assist in decisions regarding treatment and future care of the issue. Medical imaging is absolutely necessary when tracking the progress of an ongoing illness. MRI’s and CT scans allow the physician to monitor the effectiveness of treatment and adjust protocols as necessary. The detailed information generated by medical imaging provides patients with better, more comprehensive care. Medical Scanner Rovich Diagnostic

Conclusion

There are a variety of types of scanners and their specific capabilities, but the most important ones are MRI, CT, PET and Ultrasound. The inclusion of these types of scanners in a hospital has been shown to reduce mortality rates by up to 15%. In order to more thoroughly examine organs during this type of scan, we need better techniques for scanning and extracting images. The MRI scanner can be used but it has limitations such as not being able to see into soft tissues such as the brain without contrast or intravenous dye.
