The electronic image produced at the input side of a television camera is also called?

The electronic image produced at the input side of a television camera, particularly in the context of fluoroscopy and imaging systems, is referred to as an electronic image. This term specifically describes the type of image generated as a result of the conversion of radiological data (such as X-rays) into an electronic format that can be displayed, processed, and analyzed using electronic devices.

An electronic image is critical in the function of fluoroscopy systems, as it allows for real-time visualization of dynamic processes within the body, helping both in diagnostics and in guiding interventional procedures.

The other terms like X-ray image and visible image refer to different contexts; an X-ray image specifically refers to the visual representation of structures inside the body created by X-ray photons interacting with various tissues, while a visible image refers more broadly to any image perceivable by the naked eye, which does not encompass the digital processing aspect of fluoroscopic imaging. Thus, the correct answer accurately highlights the nature of the image being referred to in the context of this question.
