When it comes to medical imaging, an x-ray photograph, also known as a radiograph, is an essential diagnostic tool. However, if you're looking for synonyms, there are a few options to choose from. One alternative term is "roentgenogram," which is named after the German physicist Wilhelm Röntgen, who discovered x-rays in 1895. Another option is "x-ray image," which is a more general term that can encompass different types of x-ray images, such as computed tomography (CT) scans or magnetic resonance imaging (MRI) scans. Additionally, "radiographic image" can be used as an umbrella term that covers x-rays, CT scans, and other forms of medical imaging.
