what is axial view in ct?

CT scans use X-rays, radiation detectors and computers to produce images or "slices" through the body. In most cases, the images are in the axial plane -- a view looking down through the body. ... With proper processing, these other views are of similar quality to the original axial images.

The term “computed tomography”, or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine's computer to generate cross-sectional images—or “slices”—of the body.

A CT (computerized tomography) scan is a combination of a series of X-ray images taken at different angles; the CT uses a computer to create images from these X-rays. An MRI (magnetic resonance imaging) is a scan that uses magnetic fields and radio waves to produce a detailed image of the body's soft tissues and bones.

Like other X-ray imaging exams, CT scans expose you briefly to a small, targeted amount of ionizing radiation. The radiation helps create an image of structures inside your body.

The axial skeleton consist of: the skull, hyoid bones, vertebral column, ribs, and sternum.

CT scan. A computerised tomography (CT) scan uses X-rays and a computer to create detailed images of the inside of the body. CT scans are sometimes referred to as CAT scans or computed tomography scans.

CT scan: Computed tomography scan. ... CT stands for computed tomography.

A CT scan shows a cross-sectional view of the patient. In some cases, a CT study doesn't need to use a contrast agent. It can often provide better information than an IVP. However, it does result in an increased amount of radiation.

The axial plane of a fold is the plane or surface that divides the fold as symmetrically as possible. The axial plane may be vertical, horizontal, or inclined at any intermediate angle.

The CT scanner is the machine that takes special X-ray films. The CT scanner uses focused X-ray beams that are shot through your body. A certain pattern is created when these X-rays strike a special detector. A computer connected to this detector creates images based upon this pattern.

The axial skeleton together with the appendicular skeleton form the complete skeleton. Another definition of axial skeleton is the bones including the vertebrae, sacrum, coccyx, ribs, and sternum.

Computed tomography (CT) of the abdomen and pelvis is a diagnostic imaging test used to help detect diseases of the small bowel, colon and other internal organs and is often used to determine the cause of unexplained pain. CT scanning is fast, painless, noninvasive and accurate.

Helical CT has expanded the traditional CT capability by enabling the scan of an entire organ in a single breath-hold. ... The difference in the naming convention between helical and spiral CT is due mainly to different CT manufacturers. For all practical and technical purposes, there is no difference between the two.

Computed tomography (CT) is an imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. It is sometimes called computerized tomography or computerized axial tomography (CAT).

A CT scan generates high-quality, detailed images of the body. It's a more powerful and sophisticated x-ray that takes a 360-degree image of the spine, vertebrae and internal organs. You may have a contrast dye injected into your blood so the doctor can see your body structures more clearly on the CT scan.

Optical coherence tomography (OCT) is a new imaging technique that allows noninvasive, high resolution, cross-sectional imaging of transparent and nontransparent structures. The greatest advantage of OCT is its resolution. Standard-resolution OCT can achieve axial resolution of 10 to 15 μm.

An angiogram is a specific type of CT scan with contrast. In a CT angiogram the contrast is timed so that it will highlight either the arteries or veins (venogram) of interest. ... For the abdomen and pelvis, contrast timing is more complicated, because there are both systemic and portal venous capillary beds.
