Question

In which technique are tissues other than the surface of a structure excluded by setting a threshold value and eliminating pixels above or below that threshold?

A. Maximum intensity projection
B. Virtual endoscopy
C. Thresholding
D. Multiplanar reconstruction

Answer 1

Thresholding is the technique where a threshold value is set to exclude tissues other than the surface of a structure by eliminating pixels above or below that threshold.

Step-by-step explanation:

The technique where tissues other than the surface of a structure are excluded by setting a threshold value and eliminating pixels above or below that threshold is known as C. Thresholding. This method is widely used in medical imaging, such as MRI and CT scans, to distinguish between different types of tissues and to isolate regions of interest. By selecting an appropriate threshold, clinicians can enhance the visibility of certain areas, enabling more precise diagnosis and treatment planning.
