Abstract:
Galucho SA is a Portuguese industrial company founded in 1920, remaining its shareholder body over time and to this day within the same family. It is today and since 2014, managed by the third and fourth generation, assisted by a group of professional managers, one of whom is a member of the Board of Directors together with the family elements. The initial idea of the intervention was prepared for the advanced change in the models and management systems, until then supported in the logics and principles of "Mass Production" (Womack, Jones, & Ross, 2010), for the philosophy of "Lean Production" with all the significant impacts of organizational transformation (Quinn, 2006) and Ledbetter (2018). The work goes through several phases, which analyse the principles of strategic management, definition of objectives and effective implementation of strategies (Grant, 2016). The initial change would always have to be supported in fundamental pillars of action, in which we highlight the clear definitions of the Purpose, the study of Processes of greater preponderance in the management of the company and the clear involvement of people at all hierarchical levels fostering learning (Shook , 2010) and (Burkett, 2016).

Abstract:
Optimization of radiation dose is very important in protecting patients against the dangers of x-ray radiation. Optimization of the dose should be able to provide image quality that is acceptable to radiologists for diagnostic purposes with the lowest possible doses. The optimization tool in computed tomography scanner (CT scan) is known as the diagnostic reference level (DRL). However, the use of DRL has limitations since the dose received by the patient is not according to their needs. The DRL is obtained from 75% of the patient dose distribution with a standard size of 70 kg. Therefore, DRL does not fully meet the requirements for optimizing radiation dose. This study aims to determine the dose optimization based on the acceptable quality dose (AQD) in thoracic CT examination. This study involved 80 patients who had undergone a thorax examination using a contrast agent. All images in this study were obtained with digital imaging and communication in medicine (DICOM) format. The results of the analysis in this study stated that the patient dose based on the estimated value using the AQD principle in this study showed that the mean CTDIvol and DLP values were smaller than those using the Indonesian DRL principle. The values indicated in the application of the AQD principle and not applied, respectively, were 8.92 mGy and 9.75 mGy for the patient's weight range of 41-50 kg. 8.82 mGy and 9.72 mGy for the patient weight range of 51-60 kg. 8.99 mGy and 9.90 mGy for the patient weight range 61-70 kg. 7.74 mGy and 8.68 mGy for the weight range of patients 61-70 kg. The results of this study indicate that the use of the AQD principle can also cover the shortcomings of the DRL principle because the AQD principle also takes into account optimization parameters such as image quality. The image parameters in AQD are based on the X-ray attenuation function that represents the patient's dimensions and tissue quality in the form of SSDE values.
