Final Answer:
The value of the mAs for the given radiographic image is 50 mAs, thus the correct option is b.
Step-by-step explanation:
The mAs (milliampere-seconds) value in radiography is calculated using the formula: mAs = mA × time (seconds). Given the parameters, mA = 500 and time = 0.1 seconds. Thus, the mAs would be mAs = 500 mA × 0.1 sec = 50 mAs.
In this scenario, the milliampere (mA) is 500 and the exposure time is 0.1 seconds. The mA represents the current passing through the X-ray tube, while the time denotes the duration of exposure. Multiplying these two values gives us the mAs, which quantifies the quantity of radiation delivered during the exposure.
The mAs value is crucial in radiography as it directly influences the amount of radiation reaching the image receptor. Altering the mAs can affect image quality and exposure; for instance, increasing mAs enhances the brightness and detail in the image but also elevates patient radiation dose. In this case, with a calculated mAs of 50, it indicates the total exposure delivered during the radiographic imaging process, ensuring a balance between image quality and patient safety by providing adequate exposure for a diagnostic image without excessive radiation dose (option b).
