Aims. The aim of the study is to prove that the technical quality of the image is of inferior technical quality when placed under neonates in the incubator with the lid closed during exposure, than when placed under neonates outside the incubator in the neonates cushion assuming that we do not change the technical parameters. Methods. The research was organized as a cross-sectional study on archival data from the EXA PACS image archives of the image storage system of the Radiology Department of the Clinical Hospital Holy Spirit, Zagreb. Data were collected from the medical history by a direct evaluation of the technical quality of the X-ray chest images of neonates using the Likert scale of satisfaction of three radiology specialists. We will compare the images of premature babies so that we will only use X-ray chest images of patients from the EXA PACS image storage system of the Department of Radiology of the Clinical Hospital Holy Spirit, Zagreb, which are appropriate for us by the method of imaging. Results. There is no significant correlation between the exposure parameters of the recording in relation to the body weight of the premature infant and the average technical grade of X-ray chest imaging of the premature infant regardless of the recording mode (with the incubator lid inside the incubator and without the incubator cover in the recording pad). Therefore, it is not possible to determine the ideal exposure parameters for the ideal technical quality of X-ray chest imaging of neonates. Regarding the attenuation of incubator cover radiation, we obtained the result that the incubator cover attenuates 24.19 (±0.28) %. Conclusions. With this research work we found that there is no significant correlation between the technical quality of the X-ray chest image of premature infants and the technical parameters when recording the X-ray chest image between the two groups of subjects (recorded in an incubator with an incubator lid and recorded outside the incubator in a cushion for neonates). Also, there is no significant difference between the technical parameters in relation to the body weight of the premature infant or the difference in the technical grade of the X-ray chest image of the premature infant between the groups (taken with the lid and without the incubator lid). However, we have also concluded that the incubator cap attenuates 24.19 (±0.28)%, or that the absorbed dose is 24.19% smaller if the X-ray chest imaging of the neonates was performed through the incubator cap relative to without the incubator lid.
