Geriatric patients generally require higher central ray (CR)centering than younger patients.

Question

Quizplus · Accepted Answer

Geriatric patients often have degenerative changes in their spine and joints, which can result in more severe osteoporosis, decreased bone density, and increased likelihood of vertebral fractures. This can make it more difficult to obtain an accurate image, requiring more precise CR centering to ensure that the image is properly aligned and focused. Additionally, aging skin can be thinner and more prone to damage, so higher CR centering can help to minimize the risk of exposure-related skin damage.
