A lack of suitable dosimetric quantities for application in diagnostic radiology is noted by Dr Moores. It is concluded by Dr Moores that it is not possible to adhere to the basic principles of the International Commission on Radiation Units and Measurements (ICRU) regarding patient dosimetry in diagnostic radiology due to the extremely wide variety of quantities and units employed. The conclus...

BACKGROUND Dosimetric comparison of two dimensional (2D) radiography and three-dimensional computed tomography (3D-CT) based dose distributions with high-dose-rate (HDR) intracavitry radiotherapy (ICRT) for carcinoma cervix, in terms of target coverage and doses to bladder and rectum. MATERIALS AND METHODS Sixty four sessions of HDR ICRT were performed in 22 patients. External beam radiothera...

Background: Best dose distribution in target volume and control of Organ at Risk (OAR) dose are the two main goals in brachytherapy. Materials and Methods: In this study in vivo dosimetry in 4 rectal points was performed by Transillumination Dosimeter (TLD) s and the measured doses were compared in different patients. One point was reported to have the maximum dose in each patient and the very ...

PURPOSE To present the results of dose homogeneity analysis for breast cancer patients treated with image-based conformal interstitial brachytherapy, and to investigate the usefulness of the ICRU recommendations. MATERIAL AND METHODS Treatment plans of forty-nine patients who underwent partial breast irradiation with interstitial brachytherapy were analyzed. Quantitative parameters were used ...

The paper gives an overveiew of radioecological concepts, reference information on plants and soils used in the project. Main classification schemes applied to summarize the data on radionuclide transfer to plants are also described. Generic quantities and units used in the current document are also given. They are mainly defined according to the the ICRU 65 report. 1. DEFINITIONS, QUANTITIES A...

INTRODUCTION Wide agreement has been reached among the main Bodies and Organizations involved in standardization of radiation protection to define as operational quantity for individual monitoring of external exposure, the personal dose equivalent, Hp(d) (1,2,3). However, as Hp(d) is defined in the human body, it is not a measurable quantity. In practice, it has to be estimated from the indicat...

background: best dose distribution in target volume and control of organ at risk (oar) dose are the two main goals in brachytherapy. materials and methods: in this study in vivo dosimetry in 4 rectal points was performed by transillumination dosimeter (tld) s and the measured doses were compared in different patients. one point was reported to have the maximum dose in each patient and the very ...

The purpose of this study was to evaluate the feasibility of assessing bladder and rectal point doses, using orthogonal radiographs without treatment planning, for vaginal cylinder applicator (VC), high-dose-rate (HDR) vaginal cuff brachytherapy (BT) after hysterectomy. Thirty-three VC HDR BT treatment plans from 31 postop- erative endometrial cancer patients were retrospectively analyzed. Sing...
