20 sie 2019 · X-Y, or azimuthal, tube current modulation (aTCM) allows a further degree of fine-tuning of the radiation output to match the projection attenuation.
Cartesian coordinates define on a physical cubic corner (CC) with the corner tip as the origin and three corresponding line angles as (x, y, z)-axes.
15 lip 2016 · The basic principles of CT involve physical mechanisms that are shared with x-ray imaging, plus mathematical techniques that exceed the human visual perception of 2D images. A common technical description can be used to describe both the image formation process and the image visualization task.
11 sty 2024 · Computed tomography (CT), also known as, especially in the older literature and textbooks, computerized axial tomography (CAT), is an imaging modality that uses x-rays to build cross-sectional images ("slices") of the body.
The x and y axes (in-plane) refer to the left to right and front to back imaging planes. The z axis (through-plane) refers to the head to toe axis and is also used to define the sFOV and the scan time. Figure 2.12 illustrates the x, y and z axes of a CT image. The axial data set is the original raw data set and is the least post-processed of ...
There are three standard anatomic planes that are also used to display data for CT scans: horizontal (or axial ) coronal (cutting the body into slices that go from anterior to posterior or posterior to anterior)
Review the different image reconstruction planes, which include axial, coronal, and sagittal planes and are made possible using volumetric acquisition CT.
