Which is a common use of X-ray imaging in medical settings?

X-ray imaging is commonly used in medical settings to visualize bone fractures due to its ability to provide clear images of the bony structures within the body. This modality is particularly effective because X-rays can easily penetrate through soft tissues but are absorbed by denser materials like bone, allowing for a detailed depiction of fractures, dislocations, and other skeletal issues.

The other options, while related to medical assessments, do not accurately reflect the primary uses of X-ray technology. Measuring blood pressure, monitoring heart rate, and evaluating respiratory function involve different diagnostic tools and techniques, such as sphygmomanometers, electrocardiograms, and spirometry, respectively. These tools are specifically designed for their respective functions and do not utilize X-ray imaging, which is tailored for visualizing internal structures, particularly bones and some denser tissues.
