2)Clearly delineates the VOI
3)Improves the visibility of recorded details by reducing the amount of scatter radiation that reaches the IR
4)Decreases the radiation dosage by limiting the amount of scatter from the patient
A) 2 and 3 only
B) 1, 2, and 3 only
C) 1, 2, and 4 only
D) 1, 2, 3, and 4

Good collimation practices result in improving the quality of the image by clearly delineating the VOI (volume of interest), reducing scatter radiation that can cause image blurring and reducing radiation dose by eliminating the scatter emanating from outside the region of interest. It also reduces histogram analysis errors caused by inclusion of irrelevant areas in the image. Therefore, options 1, 2, and 3 are correct. However, option 4 is incorrect as reducing radiation dose is not the main goal of collimation, but rather a positive side effect.
