Question 1

The most familiar single sensor used for Image Acquisition is
A)microdensitometer
B)photodiode
C)cmos
D)none of the mentioned

Accepted Answer

A photodiode is a common single sensor used for image acquisition due to its ability to convert light into an electrical signal.

Question 2

A geometry consisting of in-line arrangement of sensors for image acquisition
A)a photodiode
B)sensor strips
C)sensor arrays
D)cmos

Accepted Answer

Sensor strips are used in an in-line arrangement for image acquisition, allowing for the sequential capture of images or parts of an image as the strip moves across the field of view.

Question 3

CAT in imaging stands for
A)computer aided telegraphy
B)computer aided tomography
C)computerised axial telegraphy
D)computerised axial tomography

Accepted Answer

CAT in imaging stands for Computerised Axial Tomography, which is a process that uses computer-processed combinations of many X-ray measurements taken from different angles to produce cross-sectional images of specific areas of a scanned object, allowing the user to see inside the object without cutting.

Question 4

The section of the real plane spanned by the coordinates of an image is called the _____________
A)spacial domain
B)coordinate axes
C)plane of symmetry
D)none of the mentioned

Accepted Answer

The section of the real plane spanned by the coordinates of an image is referred to as the spatial domain, which deals with the arrangement of pixels or points in a two-dimensional space.

Question 5

The difference is intensity between the highest and the lowest intensity levels in an image is ___________
A)noise
B)saturation
C)contrast
D)brightness

Accepted Answer

Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view.
