How to check bone density at home?

I've been reading about the importance of maintaining healthy bone density, but I'm wondering if there's a way to monitor it at home without going to a doctor's office. Could you please elaborate on the most practical methods available for checking bone density at home? I'm specifically interested in knowing if there are any self-administered tests or devices that could provide me with an accurate assessment. Additionally, are there any lifestyle changes or dietary adjustments I should make to promote healthy bone density? I'd appreciate any insights you could offer on this topic.
