Nuclear medicine dosimetry.
A brief overview is provided of the history of the development of internal dose methods for use in nuclear medicine. Basic methods of internal dosimetry and the systems that have been developed for use in nuclear medicine are described. The development of the MIRD system and the International Radiopharmaceutical Dosimetry Symposium series is outlined. The evolution of models and tools for calcu...
متن کاملChallenges in Nuclear Medicine Radiation Dosimetry
In spite of considerable progress, much remains to be done in the estimation of absorbed doses to organs and tissues in the body and in the prediction of biological effects from radiopharmaceuticals. In patients undergoing diagnostic procedures, the biokinetics of the radionuclide has to be determined for a number of representative patients. When radiopharmaceuticals are used for therapy, it is...
متن کاملApplication for internal dosimetry using biokinetic distribution of photons based on nuclear medicine images*
OBJECTIVE This article presents a way to obtain estimates of dose in patients submitted to radiotherapy with basis on the analysis of regions of interest on nuclear medicine images. MATERIALS AND METHODS A software called DoRadIo (Dosimetria das Radiações Ionizantes [Ionizing Radiation Dosimetry]) was developed to receive information about source organs and target organs, generating graphical...
متن کاملWhole body phantoms for the determination of dosimetry parameters needs for patients in nuclear medicine [Persian]
This study aims to give data concrning phantom material made in Iran i'rom a natural rubber which is used for obtaining calibration data for patient dose measurements in nuclear medicine applications of radionuclides for therapy and diagnosis. Is showed to be a tissue equivalent material cheap (25000 Rials the material itself and 35000 Rials the process of casting and moulding etc.), easi...
متن کاملComparative Analysis of Dosimetry Parameters for Nuclear Medicine
For years many have employed the concept of "total-body dose" or "whole-body dose," i.e., the total energy deposited in the body divided by the mass of the body, when evaluating the risks of different nuclear medicine procedures. The effective dose equivalent (H ), first described in ICRP E Publication 26, has been accepted by some as a better quantity to use in evaluating the total risk of a p...
