What is the main goal of collating the x-ray beam during radiographic examinations?

The main goal of collating the x-ray beam during radiographic examinations is to decrease the dose to both the patient and the technician. Collimation involves limiting the size and shape of the x-ray beam to the area of interest. By doing this, unnecessary radiation exposure to surrounding tissues and organs is minimized, which helps protect the patient from excessive radiation. Additionally, it reduces the exposure to healthcare personnel working in the vicinity, further ensuring safety in radiographic practices.

This technique also contributes to improving the quality of the image by reducing scatter radiation, though that isn't its primary goal. The primary focus remains on radiation safety and dose reduction, making it a fundamental practice in radiographic imaging.
