“…The tube focus to the patient surface distance ( d FSD ) must be calculated ( Eq. (1a ) or ( 1b )) [59] . The d FSD is calculated by subtracting the thickness of the patient ( t p ) from the tube focusto-patient support distance ( d FTD ) for CR or DR equipment as indicated in Eq.…”

“…As a result of this, every exposure to diagnostic x-rays needs to be justified and optimized in terms of risk and benefit [2]. One of the major ways of assessing radiation dose received in diagnostic and therapeutic radiography is monitoring of patients during the examination [3]. Diagnostic X-rays are used for diagnosing diseases and other problems during medical examinations.…”

This study was conducted to assess the amount of dose received by patients undergoing routine x-ray examinations at Federal Teaching Hospital, Gombe in Gombe State, Nigeria. Entrance skin doses (ESDs) for different kinds of x-ray procedures, include Posterior Anterior (PA) and Lateral (Lat) chest, Anterior Posterior (AP) Abdomen, AP pelvis, AP and Lat lumber spine and PA and Lat skull were assessed using standard exposure parameters. Data were obtained from eighty (80) patients who were exposed to diagnostic X-ray during their regular X-ray examinations. The patients’ age ranged from 1 to 80 years, while the weight was between 20kg and 100kg and height of these patients was between 95.0cm and 171cm. The skin dose of each patient was evaluated using a formula, based on the radiographic exposure parameters of kVp, mAS, SSD, the X-ray tube and the total filtration of the beams. The mean entrance skin dose ranged from 0.016 mGy to 3.168 mGy. Eventually, the ESDs measured for these x-ray procedures were found to be below the maximum permissible limits set by Nigeria Basic Ionizing Radiation Regulation and all the examinations conducted showed that there is a good correlation between the entrance skin doses and body mass index for the studied subjects. This implies that patients with higher body mass index will received more dose than the patients with low body mass index.

“…In fact, the doses delivered to patients during medical imaging examinations are not sufficiently controlled and the working protocols for a given examination differ from one hospital service to another. These variations indicate that good imaging technique is needed to reduce the dose to patients at the lowest practicable level to respond to the clinic and make the diagnosis [1]. These large variations in the doses delivered to patients for the same examination also show a crucial importance for the study of dose variations [2], for quality assurance and standardization of protocols [3], in order to guarantee the optimization of doses to patients.…”

Background. The purpose of this study was to estimate the doses delivered to adult patients during explorations of the sinuses and coastal grill whose attention in dosimetric terms is neglected because of the low demand for diagnosis. But yet dosimetric values are very high. Materials and Methods. The present study was transversely descriptive and was conducted between April and July 2016. The data were collected on 50 adult patients of mass of 70±10kg at the Regional Hospital of Ngaoundere (HRN). The dose at the entrance of the patients' skin was evaluated through the theoretical methods derived from the Davies model according to the 75th percentile calculations. Results and Discussion. The entrance skin doses obtained in mGy were, respectively, of 7.2±0.2 for sinuses and 5.27±0.1 for coastal grill. The present study found many variations in doses during radiological investigations. These variations allowed us to understand that the notions of quality of the radiographic image, insurance, and quality control of the radiological equipment are tributary, abstract, and often theoretical because doses delivered are not sufficiently optimized. Conclusion. The dosimetric analysis remains very worrying because the various procedures show that an improvement of the practices especially with respect to the technical parameters and the protocols must be considered. Therefore a strengthening of radiological protection skills of radiological manipulators (continuing education and retraining) would contribute to a better protection of patients.
