“…This reduction in patient dose by using flat panel detectors is also reported by Sjoholm et al, and Metaxas et al, (Sjöholm, 2005;Metxas, 2019). Comparing present study results with similar study in India by Bhupinder et al, it is observed that for skull Lat the percentage decrease of radiation dose is found to be 86% (Rana et al, 2018). The mean patient weight of both the studies is comparable.…”

Purpose: Exposures to medical ionizing radiations elevate the risk of stochastic effects such as cancer in exposed individuals. It is of utmost importance to monitor the radiation doses delivered to patients and their optimization to reduce the associated radiation risks without limiting the diagnostic information. Methods: Entrance surface air kerma (ESAK) in a total of 64 adult patients in diagnostic digital Xray examinations were calculated and effective doses were estimated as per International Atomic Energy Agency (IAEA). Results: Median ESAK (mGy) and associated effective doses obtained were skull PA (0.45mGy, 0.005mSv) and skull Lat (0.25mGy, 0.003mSv). Results were compared with UK diagnostic reference levels and studies in India.Conclusion: The comparison revealed that the calculated ESAK and effective dose values wereless than the published literature. ESAK values reported in this study could further contribute toestablishing LDRLs.

“…However, studies aiming to investigate local radiographic practices in digital radiography are limited. 10,11 Features associated with DR like post-processing and large dynamic range can influence the contrast and density of image and can result in overexposures without the knowledge of the operator. 12,13 Present study aims to examine the current state of radiographic practice in chest digital radiographic examinations in a public teaching hospital in Delhi, India.…”

To investigate the current radiographic practices in a public tertiary care teaching hospital in digital radiography set-up, the study aimed to calculate the entrance surface air kerma (ESAK), kerma area product (PKA), and effective doses in chest PA, and AP digital radiographic examinations. Chest radiography is the most common examination performed worldwide. Due to the frequency of these examinations, its contribution to the collective dose is considerable. Also, various international authorities have recommended guidelines for local dose surveys for radiation protection and optimization. IAEA recommended protocol was used to calculate the patient doses. The 3 rd quartile values of ESAK and PKA obtained are 0.17 mGy and 0.27 Gycm 2 for chest PA; 0.38mGy and 0.21 Gycm 2 for chest AP. The estimated mean effective doses are 0.017 (ED from ESAK), 0.037 (ED from PKA) for chest PA and 0.041 (ED from ESAK), 0.028 (ED from PKA) for chest AP. The results obtained are compared with ESAK, PKA, and effective dose values of previously published literature. The estimated doses could be used as a baselines value for setting up of future local diagnostic reference levels (LDRLs) and for optimization of patient doses in diagnostic radiology.

“…6 Any increase in tube voltage must be followed by a reduction in tube current and irradiation time so that the appropriate radiation intensity to produce a sufficient image quality is employed. [7][8][9] The patient dose in a DR examination is an issue highlighted by the Nuclear Energy Regulatory Agency of Indonesia (BAPETEN) and the Indonesian Hospital Accreditation Committee (KARS). The BAPETEN has published a webbased application for recording patient data called SI INTAN, and has established diagnostic-reference levels (DRL) for all diagnostic radiography.…”

Purpose: The purpose of this study was to develop software to automatically measure the main areas of the chest, i.e. soft tissue, bone, and air and to implement it in Kraton Regional General Hospital for designing a specific dosimetrical phantom for chest digital radiography (DR) examination.Methods: This study was a retrospective study on all DR images from 2015 to 2019, and computed tomography (CT) images of 102 patients in Digital Imaging and Communications in Medicine (DICOM) format files scanned from January-December 2019 at the Kraton Regional General Hospital. We evaluated the number of basic DR chest examinations compared to all DR radiological examinations. We developed a MatLab graphical user interface (GUI) for automated measurement of the areas of the main chest components (soft tissue, bone, and air). We computed the areas of the main components of the chest in order to develop a specific chest phantom for DR in the hospital. In order to compute the areas of the main components, we used chest CT images of patients with clinical indications of chest tumors.Results: The basic DR chest examination comprised 59.5% of all DR examinations in the hospital during 2015-2019. The average areas of soft tissue, bone, and air within the chest in all patients were 331, 20, and 125 cm2, respectively, with values of 345, 23, and 139 cm2 for males, and 309, 15, and 103 cm2 for females. The areas were also dependent on age with values of 121, 10, 55 cm2 for patients aged 5-11 years, 371, 27, and 88 cm2 for patients aged 12-25 years, 322, 22, and 131 cm2 for patients aged 26-45 years, and 334, 19, and 126 cm2 for patients > 45 years old.Conclusion: A GUI for computing the main composition of the chest was successfully developed. The areas of chest male patients were greater than female patients. The areas of soft tissue, bone, and air were dependent on the patient’s age. Therefore, the design of dosimetrical DR phantom must consider the gender and age of the patient.
