20 sie 2019 · The technology can be subdivided into three related techniques: automatic tube current selection, varying the tube current along the z-axis of the patient, and varying the tube current in the x-y plane around the patient.
We will discuss the most common template-independent factors that can influence C t and describe how to evaluate the performance of a real-time PCR reaction. Figure 1, above, shows several parameters of the real-time reaction amplification plot.
You need to arrange the data in a 11 x 11 grid (from 0 to 10 across and down). At the intersection of the X and Y values enter the Z value. Then chart the data as a 3D column chart with the right-most template in the drop-down.
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 use of cone-beam computed tomography (CBCT) in medical field can help the clinicians to visualize the hard tissues in head and neck region via a cylindrical field of view (FOV). The images...
28 lut 2012 · An object O (x, y, z) is considered as a superposition of n layers of the same thickness along z axis, all located in planes parallel to the plane (x, y) and perpendicular to z (Fig. 1). Each layer represents a section in the object to be reconstructed.
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.
