  • Reactance

    In an alternating current (a.c.) circuit, there exists a form of opposition that is purely related to either inductance or capacitance. This opposition, measured in ohms, represents the component of impedance that is distinct from resistance. Specifically, inductive reactance arises as a result of capacitance.  

  • Ct raw data

    The term used for scan data in digital form that is stored in a dedicated section of the System Disc is called “Raw Data.” This raw data cannot be directly utilized by the system to generate a slice image until it undergoes additional electronic manipulation known as “processing.” Processing involves applying mathematical operations to the…

  • Rare earth

    The term commonly used to refer to intensifying screens that contain one or more of the rare earth elements and utilize their absorption and conversion properties in x-ray imaging is “Rare Earth Screens.” These screens are part of a screen-film system used for x-ray imaging and are considered “fast” exposure systems. They enhance the efficiency…

  • Rapido – mat

    The Picker rapido table is equipped with the comprehensive processing system designed by Picker.  

  • Rapido

    The Picker automatic cassetteless radiographic system utilizes a vacuum-based exposure area to ensure close contact between the screen and film, eliminating the need for traditional cassettes.  

  • Rapid drip study

    In intravenous pyelography, the term used to describe the process of administering contrast media through an intravenous infusion, as opposed to a single rapid injection of contrast material, is “continuous infusion.”  

  • Radium needle

    A needle-shaped radium cell, typically made of platinum-iridium or gold alloy, specifically designed to be inserted into tissue.  

  • Radiopague

    X-rays and other types of radiation are unable to significantly penetrate or pass through it.  

  • Radiometallography

    X-ray equipment is employed to analyze the crystal structure and additional properties of metals and alloys. This examination enables a comprehensive understanding of their composition and structural features.  

  • Radiocesium

    Cesium-137, a noteworthy radioisotope obtained from the waste generated by nuclear reactors, possesses various practical applications. It finds utility in the sterilization of food products and serves as a substitute for radium in certain medical procedures. With a half-life of 37 years, this particular radioisotope exhibits a gradual decay process over an extended period of…
