Modelling of Dose Area Product by Application of Computer Programming in Diagnostic Radiology

The study seeks to develop a means of Quality Control (QC) in radiological procedures, with the aid of Dose Area Product (DAP) method, that can be used as a reference level in radiology.Some samples of x-ray radiographic films were collected from various hospitals.The Optical Densities (OD) of each radiographic films were measured, using the instrument, film densitometer, after which they were converted to the amount of absorbed dose, by each film, representing the various human body parts or anatomy.Afterwards, the DAP for each film was calculated using a computer programming code written in WAMP (Windows, Apache, MySQL and PHP).The DAP ranges from 741.6 cGy.cm 2 to 10, 853.5 cGycm2, corresponding to Skull (SK) and Chest (CH) examinations respectively.The various film areas were between 720 cm 2 to 1,505 cm 2 .Optical Densities were from 0.30 to 2.30 and the absorbed dose, X varied from between 0.83 cGy to 9.14 cGy.The DAP on the average was found to be 4,579 cGy.cm 2 , which can the said to be a reference level for use during diagnostic or radiological procedures.
