Three dimensional images of the internals are obtained using X-rays in

Options

A. Radiography
B. Computed tomography
C. MRI
D. EEG

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the method that uses X-rays to obtain three-dimensional images of internal organs.

2. **Identifying the Techniques**: The options presented include:
- Radiography
- Computed Tomography (CT)
- Magnetic Resonance Imaging (MRI)
- Electroencephalography (EEG)

3. **Analyzing Each Technique**:
- **Radiography**: This technique uses X-rays but produces a two-dimensional image. Therefore, it does not meet the requirement of generating a 3D image.
- **Computed Tomography (CT)**: This technique also uses X-rays but is specifically designed to create three-dimensional images of internal organs. It combines multiple X-ray images taken from different angles and uses computer processing to create a detailed 3D representation.
- **Magnetic Resonance Imaging (MRI)**: MRI uses strong magnetic fields and radio waves to create images of organs and tissues. It does not use X-rays, so it is not the correct answer.
- **Electroencephalography (EEG)**: EEG measures electrical activity in the brain using electrodes. It does not involve X-rays and is specifically used for brain activity analysis, not for imaging internal organs.

4. **Conclusion**: Based on the analysis, the only technique that uses X-rays to obtain three-dimensional images of internal organs is **Computed Tomography (CT)**.

**Final Answer**: Computed Tomography (CT)
