What is the ideal distance between an x-ray tube and an x-ray cassette in standard radiographic procedures?

• A. $100\mathrm{cm}$
• B. $50\mathrm{cm}$
• C. $1m$
• D. $10\mathrm{cm}$

Answer: (A)

Verified step by step guidance

1. Understand that the distance between the x-ray tube and the x-ray cassette is known as the Source-to-Image Distance (SID), which is a standard parameter in radiographic procedures.
2. Recognize that the SID affects image quality, magnification, and radiation dose; therefore, it is standardized to ensure consistent and optimal imaging results.
3. Recall that the commonly accepted standard SID in most radiographic procedures is 100 cm, which is equivalent to 1 meter.
4. Note that this distance balances the need for clear image resolution and manageable radiation exposure to the patient.
5. Conclude that the ideal distance between the x-ray tube and the x-ray cassette in standard radiographic procedures is 100 cm (or 1 meter).
