Measurement of the Prostate Motion in External Beam Radiotherapy

Abstract:

Organ motion in Radiotherapy induce an error in the received dose by the tumour

therefore this experimental study conducted at different hospitals in Sudan

(Radiation and Isotopes Centres of Khartoum (RICK) and Antalya clinic centre in

period of 7 months, from May 2014 to December 2014.

The main objective of this study was to detect and measure the periodic

physiological prostate motion during external beam radiotherapy (inspiration and

expiration) , to accurate and continuous tumor location information , to investigate

intrafraction prostate and patient motion during radiation therapy treatments .

The data collected using Image Registration Technique and Point Mapping using

Mat Lab program.

The result of the study were (9.19±1.77 mm) for body contour and (4.22+1.07 mm)

for prostate. The motion was significantly attached the dose of radioactive which expected to be given for prostate treatment.
