Non-vascular interventional procedures:effective dose to patient and equivalent dose to abdominal organs by means of dico M images and Monte Carlo simulation Abstract

This study evaluates x-ray exposure in patient undergoing abdominal extra-vascular interventional procedures by means ofDigital Imaging and COmmunications in Medicine (DICOM)Image headers and Monte Carlo simulation. The mainaim is to assess the effective and equivalent doses, under the hypothesis of their correlation with theDose Area product (DAP)measured during each examination. This allows to collect dosimetric information all patient and to evaluate associated risks without resorting toIn VivoDosimetry. The dose calculation is performed in procedures through the Monte Carlo simulatorPCXMC(A pc-based Monte Carlo program for calculating patient doses in medical X-ray examinations), by using the real Geometrica L and Dosimetric irradiation conditions, automatically extracted from DICOM headers. The DAP measurements were also validated by using Thermoluminescent Dosemeters in an anthropomorphic phantom. The expectedlinear correlation between effective doses and DAP is confirmed with an R2 of 0.974. Moreover, in order to easily calculate patient doses, conversion coefficients, relate equivalent doses to measurable q Uantities, such as DAP, were obtained.

Through this article, we can know Dicom's all-famous medical digital imaging and communication. This paper mainly makes some calculations and experiments, and makes linear fitting. The calculation of conversion coefficients is also carried out. The article gives the software name can also be searched to see. Follow the search brief

PCXMC is a computer program for calculating patients ' organ doses and effective doses in medical X-ray examinations (radio Graphy and fluoroscopy). The doses is calculated in organs and tissues and the program calculates the effective dose with both the present Tiss UE weighting factors of ICRP Publication 103 (+) and the old tissue weighting factors of ICRP Publication (1991). The program incorporates adjustable-size paediatric and adult patient models and allows a free choice of the X-ray Examina tion technique.
