Feasibility Test

Research has been conducted to determine feasibility test of the X-ray planePA and LAT projections on chest x-ray techniques. The study using a water phantom object as a substitute for patients with variations in interval distance ofthe  100-180 cm. Measurement of radiation dose X-rays performed five repetitions , measurable doses had be read on the device electrometer. Exposition factors to the PA projection using a tube voltage of 75 kV, current and time of 3,2 mAs, the irradiation field areaof (30 x 30) cm2.For the LAT projection tube voltage of 80 kV, current and time of 6,3 mAs, and the irradiation field area of (20 x 30) cm2. It the study of the radiation dose X-ray plane projection PA and LAT is optimal is below the limit value at the level of dosage guidelines BAPETEN No 08 of 2011. Obtained PA projections are below the value of 0,4 mGy while LAT projection is below the value of 1,5 mGy. The radiation dose X-rays plane using a variation of 100-180 cm distance is still below the dose limit values ??, thus meeting the objectives anssurance quality and quality control.

Different essential radiographic parameters were studied in order to assess radiographic image quality ensuring reduction of radiation exposure in some diagnostic X-ray facilities of Bangladesh. Different parameters for developing and fixing liquid were investigated in order to eliminate improper film processing techniques. General information about intensifying screen, radiography and mammography film was also collected. X-ray tube voltage, output radiation dose and exposure time for diagnostic X-ray machines were tested to achieve significant dose reduction without loss of diagnostic information. It is found that output radiation dose varies in different diagnostic X-ray installations. 70% X-ray installations achieve the recommended value for tube voltage while 87.5% measure the exposure time appropriately. Radiation dose level at patient waiting room, dark room and around control panel was also measured. About 92.5, 85 and 77.5% installations show their results within the acceptance limit at these positions respectively which provide radiation safety for patients, workers and public in diagnostic radiology.DOI: http://dx.doi.org/10.3329/jbas.v35i1.7967Journal of Bangladesh Academy of Sciences, Vol.35, No.1, 7-17, 2011
