What term refers to imaging by sectioning through the use of penetrating waves?

  1. X-ray

  2. Ultrasound

  3. Tomography

  4. Fluoroscopy

The correct answer is: Tomography

The term that refers to imaging by sectioning through the use of penetrating waves is tomography. Tomography is a technique that produces images representing a slice or section through a three-dimensional object, allowing for detailed visualization of internal structures. This method utilizes various imaging modalities like X-rays or ultrasound, which emit waves that penetrate the body to gather information from different angles. While X-ray and ultrasound are both forms of imaging that can be involved in tomographic techniques, they don't specifically denote the sectioning aspect as directly as the term tomography does. Fluoroscopy, on the other hand, provides real-time moving images but does not generally refer to the sectioning process used in tomography. Therefore, the most accurate and encompassing term among the choices for imaging that specifically involves sectioning is tomography.
