What imaging technique produces a slice through the body using a series of x-ray photographs?

The imaging technique that produces a slice through the body using a series of x-ray photographs is the CT scan. This method employs a combination of x-ray images taken from multiple angles to generate cross-sectional views, or slices, of organs and other structures within the body.

In contrast, traditional x-rays provide a two-dimensional view that lacks the depth and detail necessary for comprehensive analysis of complex internal structures. Ultrasound utilizes sound waves to create images and is particularly useful for visualizing soft tissues and fluid-filled areas but does not provide the same level of detail as a CT scan. MRI, or magnetic resonance imaging, relies on magnetic fields and radio waves to produce detailed images of soft tissues, making it advantageous for certain conditions but not applicable for x-ray based imaging methods.

By using x-ray technology in a rotational fashion, a CT scan captures detailed, high-resolution images that are invaluable in oncology for diagnosing and monitoring tumors, planning treatment, and assessing treatment responses.
