ITAR: A modified TAR method to determine depth dose distribution for an ophthalmic device that performs kilovoltage x‐ray pencil‐beam stereotaxy

Abstract

Equipment selection, measurement techniques, and formalism for the determination of dose rate to the macula during stereotaxy for AMD have been determined and are strongly recommended by the authors of this paper to be used by clinical medical physicists.

Comparison and uncertainty evaluation of different calibration protocols and ionization chambers for low‐energy surface brachytherapy dosimetry

“…The first one has been used for measurements of the Xoft x-ray source, 6 the INTRABEAM unit, 8 and the Esteya system, 10 as well as for measurements with a 100 kVp source and field sizes as small as 4.2 mm diameter. 18 Measurements with both chambers were not compared in those previous studies. Recently, Fulkerson et al 7 used both the T34013 and the A20 chambers for measurements of the Xoft x-ray source and concluded that the first chamber had a large and counterintuitive magnitude in the stem effect, making it unsuitable for the dose measurements, so the use of the A20 chamber was since then recommended for reference dosimetry of the Xoft x-ray tube.…”
