Objective: We aimed to investigate the image quality of paranasal sinus computed tomography (CT) scans obtained with the “Advanced intelligent Clear-IQ Engine” (AICE) software and ultra-low dose parameters in patients with prediagnosed rhinitis, sinusitis or nasal septum deviation. -/- Methods: The first 50 patients (31 men and 19 women, aged 18-70 years) who agreed to participate in our prospectively planned study were included in the study. Imaging of the patients was performed with a 160-slice multidetector CT device Canon Aquilion Prime (...) SP (Canon Medical Systems, Otawara, Japan). Tube voltage of 80 kV and tube current of 40 mA were chosen. The effective radiation dose (ED) was calculated based on the “dose-length product” (DLP) information of each patient. Evaluation of images was made on reformat images made with “AiCE Bone” filter in the axial and coronal planes. All images were double-blindly evaluated by 2 radiologists out of 5 points (5 = very good; 1 = not diagnostic). The visibility of 17 bilateral important anatomical landmarks examined on paranasal sinus CT was scored (0 = not visible; 2 = completely visible). In the evaluation of images, the agreement between radiologists was evaluated with Kappa statistics. -/- Results: The median ED value of the CT protocol was 0.015±0.001 mSv [range 0.012-0.017 mSv]. The overall image quality of the images in our study was interpreted as 4 (good) or 3 (moderate) for all patients. Inter-research agreement was 92%. Most of the anatomical landmarks evaluated were completely visible. Six (bilateral of three) anatomical landmarks could be partially visible in some patients. -/- Conclusion: Combining the ultra-low dose CT protocol and the AiCE reconstruction algorithm makes it possible to achieve very low ED values ​​in paranasal sinus CT scans and still obtain sufficient image quality in indications such as septum deviation and sinusitis.

The relationship between space and human occurs through the actions performed with the body. The abstraction study as an exploration of the body is one of the significant practices for first-year design students. However, there are not enough investigations for design students regarding body, space and basic design principles. This paper aims to explore the potentiality and limitations of the body-abstraction process by comparing the impact of two different educational models on students' perception and improvement. The applied methodology includes comparing (...) two design processes of the basic design course depending on parameters: Given example, source of the video, type of movement, the number of the selected-used scenes, mode of sketching, the method for production, requested outcome, the scale of the study, the material of models and critique of the video. The results present that the activation of the body through mental practice, drawing and modelling stages is critical to understand its abstract and spatial capabilities. The realisation of the potentials in the relationship between body and abstraction in spatial perception would enable us to create an advanced design process addressing more original concepts.

The first year of design education is essential for students as it is their initial interaction with the design process. Awareness of the body through dance has the potential to reveal bodily experience in space. Abstraction of embodied experience contributes to realising the significance of the body and its analytical dimension for spatial and structural design. This study investigates the impact of embodied experience and abstraction on the architectural design process and the outcome through correlation and regression analysis. We observed (...) that increasing awareness of the space through bodily movement and its drawn representation positively impacted students’ success in architectural design. Also, the measures related to space and structure mainly advanced students’ success in the final design. However, the association of the abstraction process with the final design remained limited. The study’s contribution is the systematic and statistical evaluation of the relationship between body, movement, abstraction and architectural design by constructing a set of measures from various stages of the design studio. We hope our research will provide a basis for the upcoming discourse. (shrink)
