Development of phantom for radiographic image optimization of standard patient in the lateral view of chest and skull examination

Analysis of biological tissues in infant chest for the development of an equivalent radiographic phantom

“…This phantom has a well-consolidated structure and material composition that are easily found within the specific literature. 6,11 The CT images of the PEP for the chest configuration were scanned. The thicknesses of simulator materials obtained with the Gaussian fitting were compared with the actual values of the PEP (Table I).…”

“…Homogeneous plate phantoms are important tools in radiology that help to establish optimized techniques and to ensure maximal image quality with as low as reasonably achievable (ALARA) doses. 1,2,6 However, the development of homogeneous plate phantoms in the literature has focused exclusively on adult patients. 1,2,6,7 The development of homogeneous plate phantoms for infant patients remains unexplored.…”

“…1,2,6 However, the development of homogeneous plate phantoms in the literature has focused exclusively on adult patients. 1,2,6,7 The development of homogeneous plate phantoms for infant patients remains unexplored. The ultimate goal of our research is to generate a homogeneous plate for constructing an infant chest phantom in the posterior-anterior or anterior-posterior (PA/AP) view.…”

Estudo de otimização de imagens em fluoroscopia intervencionista

“…The experimental procedure was performed with a BV Pulsera C-arm type fluoroscopic system (Philips Medical Systems; Eindhoven, The Netherlands), with images digitization. The phantom utilized in the present study was adapted for fluoroscopy, consisting of a patient simulator and a realistic-analytic phantom (7) , as shown on Figure 1, simulating human anatomy structures (8) , relevant for radiological procedures. The adaptation of the realistic-analytic phantom consisted of the implantation among radiologic procedures involving the highest radiation exposure for both patients and medical professionals involved.…”

Exploring dependence of the patints’ radiation dose on the form of power supply voltage of x-ray tube

“…In addition, there were proposals to use, as an alternative to physical metrics of a dose, tools and techniques, adapted for fast and reliable assessment of the quality of X-ray images [10] to prevent ineffective increase in the dose. Much attention is paid to the transition from the measured empirically [11,12] or calculated by numerical methods [13,14] dose of representative homogeneous [15,16] and anthropomorphic [17,18] phantom to the dose of a particular patient. In addition to the design and application of the systems for tracking the history of radiation exposure of a patient [19], optimization of other technical and clinical factors also significantly reduces the patients' and medical staff dose [20].…”
