“…Here, the prosthesis not only restores facial appearance but also significantly improves the patient’s quality of life. [ 19 ] Technological advancements have greatly improved the effectiveness of orbital prostheses. Customization through 3D printing and sophisticated imaging technologies allow for the creation of highly customized prosthetics that align with the patient’s facial contours and skin tone, providing a more natural appearance.…”

Background: Orbital tumors, arising within the bony orbit and its contents, present diverse challenges due to their varied origins and complex anatomical context. These tumors, classified as primary, secondary, or metastatic, are further subdivided into intraconal and extraconal based on their relationship with the muscle cone. This classification significantly influences surgical approach and management. This study highlights surgical experiences with orbital tumors, underscoring the importance of tailored surgical approaches based on the lesion’s site and its proximity to the optic nerve. Methods: This retrospective study at the National Institute of Cancer’s Head and Neck Department (2005–2014) analyzed 29 patients with orbital tumors treated with surgery, radiotherapy, chemotherapy, or combinations of them. Patient demographics, tumor characteristics, and treatment responses were evaluated using computed tomography (CT), magnetic resonance imaging, and positron emission tomography-CT imaging. Malignant tumors often required orbital exenteration and reconstruction, highlighting the study’s commitment to advancing orbital tumor treatment. Results: 29 patients (18 females and 11 males, age 18–88 years, mean 53.5 years) with orbital tumors exhibited symptoms such as decreased vision and exophthalmos. Tumors included primary lesions like choroidal melanoma and secondary types like epidermoid carcinoma. Treatments varied, involving a multidisciplinary team for surgical approaches like exenteration, with follow-up from 1 to 9 years. Radiotherapy and chemotherapy were used for specific cases. Conclusion: Our study underscores the need for a multidisciplinary approach in treating orbital tumors, involving various surgical specialists and advanced technologies like neuronavigation for tailored treatment. The integration of surgery with radiotherapy and chemotherapy highlights the effectiveness of multidimensional treatment strategies.

“…X-ray computed tomography is well known as a medical diagnostic tool [1][2][3], but is also widely used in industrial applications and other fields for nondestructive testing [4][5][6][7]. An uncommon representative of this technique is the ultrafast X-ray computed tomography (UFXCT) [8], which is purpose-built for the investigation of transient multiphase flow phenomena, especially for those happening in opaque vessels [9,10].…”

Ultrafast X-ray computed tomography is an advanced imaging technique for multiphase flows. It has been used with great success for studying gas–liquid as well as gas–solid flows. Here, we apply this technique to analyze density-driven particle segregation in a rotating drum as an exemplary use case for analyzing industrial particle mixing systems. As glass particles are used as the denser of two granular species to be mixed, beam hardening artefacts occur and hamper the data analysis. In the general case of a distribution of arbitrary materials, the inverse problem of image reconstruction with energy-dependent attenuation is often ill-posed. Consequently, commonly known beam hardening correction algorithms are often quite complex. In our case, however, the number of materials is limited. We therefore propose a correction algorithm simplified by taking advantage of the known material properties, and demonstrate its ability to improve image quality and subsequent analyses significantly.
