medical imaging quiz 1

Is the standard format for medical imaging files

• HL7

• DCM

• DICOM

Dicom files stores only patient data

• TRUE

• FALSE

DICOM format stores

• patients' meta data

• examination specifications

• examination images

The only reason for enhancement is to make structures easier detectable by a human observer

• TRUE

• FALSE

Image enhancement serve as some necessary preprocessing step for further automatic analysis.

• TRUE

• FALSE

•In medical imaging, image enhancement essentially

• enhances Contrast

• enhance edges

• reduce noise

• reduce size

Root Mean Square Contrast is better than global contrast as

• it is easy to calculate

• take all of the pixels in account

• depend on intensity distribution

Root Mean Square Contrast disadvantage is that it

• it is easy to calculate

• take all of the pixels in account

• It does not differentiate well between different intensity distributions

Histogram stretching enhance image contrast by

• mapping min and max levels to different levels

• distributing intensity equally over different gray levels

• clipping intensity levels

The histogram for this image is
