isodose|ˈaɪsəʊdəʊs|
[f. iso- + dose n.]
An imaginary line or surface, or a graphical representation of one, connecting points, esp. points in the body, that receive equal doses of radiation; now always used attrib., esp. of such lines and surfaces and of diagrams depicting them.
1922H. Schmitz tr. Kroenig & Friedrich's Princ. Physics & Biol. Radiation Therapy 249 To render a graphical presentation of the distribution of the dose in radiated tissue one proceeded with the conception that the equal intensity curves of like doses in a body, which we may term ‘isodoses’, are spheres which surround the center of the preparation concentrically. Ibid., The isodoses of such strong capsules as are used in deep therapy must deviate from the circular or cylindrical forms. 1923O. Glasser in Amer. Jrnl. Roentgenology X. 405 (heading) Isodose charts. Ibid. 405/2 The curves are called ‘isodoses’ a name I gave first to these curves in connection with radium five years ago. 1939Brit. Jrnl. Radiol. XII. 263/1 The isodose curves or dose contours cut out in space complex solids whose surfaces are ‘isodose surfaces’. 1950Rev. Sci. Instruments XXI. 363/1 The automatic isodose recorder..satisfies the demand for tracing radiation fields with a good accuracy in a short length of time. Ibid. 365/1 Both the speed of the isodose tracing and the accuracy..are quite adequate. 1956Hine & Brownell Radiation Dosimetry xii. 573 (caption) Isodose contours for cancer of the esophagus obtained by combining six 6 × 15-cm fields using Co60. 1966R. D. Cadle Particles in Atmosphere & Space iv. 104 Fallout patterns are maps consisting of families of isodose rate lines or contours. 1968Brit. Med. Bull. XXIV. 242/1 The computer produced a mass of figures..which were easily converted with an x–y plotter to an isodose distribution form, with which all radio-therapists are familiar. |
