Hybrid dose calculation: a dose calculation algorithm for microbeam radiation therapy

Calculation of gel dose after external radiation therapy using optical CT

In this study, the MAGIC- f polymer gel was used to determine the absorbed dose by external radiation therapy. The MAGIC- f gel was made under normal pressure and temperature conditions and irradiated with a Siemens 6MV linear accelerator at 10 × 10 cm2 and at a depth of 10 cm. While simulating the head of the accelerator unit by the Monte Carlo method with BEAMnrc code, the percentage depth do...

Estimation and calculation of radiation dose of copper-64 for nuclear medicine usage

Radioactive materials used in nuclear medicine are the radioisotopes or drugs that are identified with radioisotopes. A radiopharmaceutical transfusion is one of diagnostic methods and a radiation value approved should be measured. The nuclear medicine images of diagnostic methods can be made by a gamma camera (γ-camera). In this article, we used MCNPX2.4 for internal dosimetry assessment when ...

New formula for Calculation of Cobalt-60 Percent Depth Dose

Introduction:  On  the  basis  of  percent  depth  dose  (PDD)  calculation,  the  application  of  dosimetry  in  radiotherapy  has  an  important  role  to  play  in  reducing  the  chance  of  tumor  recurrence. The aim of this study is to introduce a new formula for calculating the centeral axis  percent depth doses of Cobalt-60 beam.   Materials and Methods: In the present study, based on ...

Calculation of dose distributions in radiation therapy by a digital computer. II. Computation of dose distrsbution in radium therapy.

Testing of the analytical anisotropic algorithm for photon dose calculation.

The analytical anisotropic algorithm (AAA) was implemented in the Eclipse (Varian Medical Systems) treatment planning system to replace the single pencil beam (SPB) algorithm for the calculation of dose distributions for photon beams. AAA was developed to improve the dose calculation accuracy, especially in heterogeneous media. The total dose deposition is calculated as the superposition of the...
