Modern medicine has exploded and doctors today can treat diseases that would never have been noticed in the past before it was too late. One of the reasons why they can do this is through advanced imaging technologies that allow health professionals to examine the body without invasive surgery.
The oldest form of modern images is still one of the most used. Radiography (as it is called using X-ray images in a medical context) works because X-rays projected onto an object show differences in density. The scan shows all the overlapping structures. Dentists in Box Hill performs radiographs to evaluate your oral health.
CT stands for “computed tomography.” A computer is used to create a three-dimensional projection based on a set of two-dimensional X-ray images. X-rays are recorded in rapid succession on a single axis of rotation. They are rich in contrast, so that small differences in tissue are easy to observe. You also have no problems with annoying overlays.
Instead of using light to photograph an object, ultrasound measures the reflection of sound to create images. Typically, this is used to search “under” a medium to show the underlying structure. With the same technology that helps bat hunts, doctors can perform ultrasounds to observe a child in the womb.
Electrocardiography (or ECG) is not the same as the other three types because, instead, it produces a projection of the electrical activity of the heart. This allows doctors to control stress in the center, especially if a patient is at risk of suffering a cardiac event or suffering a shock.
Bone density scans
Traditionally, it was thought that older patients died and then broke a hip. New research has shown that low bone density causes the pelvic bones to break and the patient to fall. Bone scans can help prevent fractures and injuries through the use of medical imaging to diagnose poor bone density and allow doctors to prescribe effective treatments before a break. Medical images of bone density are also used to identify other bone abnormalities and tumor growth.
