3D-печать в хирургии печени является новым многообещающим инструментом хирургического планирования. В обзоре приведены шесть исследований, непосредственно связанных с 3D-визуализацией печени. Однако стоимость 3-Д визуализации и время являются основными ограничивающими факторами при создании надежной модели. Со временем эта техника осуществима и применима к резекции печени и может помочь в предоперационном планировании резекции печени. 3D printing in liver surgery is a promising new surgical planning tool. The review lists six studies directly related to 3D liver imaging. However, 3-D rendering cost and time are the main limiting factors in creating a robust model. Over time, this technique is feasible and applicable to liver resection and may aid in preoperative liver resection planning.

Abstract This paper examines several research questions relating to equality and equity in Chinese higher education via an extended literature review, which in turn sheds light on evolving scholarly explorations into this theme. First, in the post-massification era, has the Chinese situation of equality and equity in higher education improved or deteriorated since the late 1990s? Second, what are the core issues with respect to equality and equity in Chinese higher education? Third, how have those core issues evolved or changed over time and what does the evolution indicate and entail? Methodologically, this paper uses a bibliometric analysis to detect the topical hotspots in scholarly literature and their changes over time. The study then investigates each of those topical terrains against their temporal contexts in order to gain insights into the core issues.

Medical Imagery

In the last years, cardiovascular diagnosis, surgical planning and intervention have taken advantages from 3D modelling and rapid prototyping techniques. The starting data for the whole process is represented by medical imagery, in particular, but not exclusively, computed tomography (CT) or multi-slice CT (MCT) and magnetic resonance imaging (MRI). On the medical imagery, regions of interest, i.e. heart chambers, valves, aorta, coronary vessels, etc., are segmented and converted into 3D models, which can be finally converted in physical replicas through 3D printing procedure. In this work, an overview on modern approaches for automatic and semiautomatic segmentation of medical imagery for 3D surface model generation is provided. The issue of accuracy check of surface models is also addressed, together with the critical aspects of converting digital models into physical replicas through 3D printing techniques. A patient-specific 3D modelling and printing procedure (Figure 1), for surgical planning in case of complex heart diseases was developed. The procedure was applied to two case studies, for which MCT scans of the chest are available. In the article, a detailed description on the implemented patient-specific modelling procedure is provided, along with a general discussion on the potentiality and future developments of personalized 3D modelling and printing for surgical planning and surgeons practice.

Over Time

The study seeks to examine the approaches taken currently with regard to scholarship on ecclesiology from the patristic era, the medieval era to that of the reformation and beyond. The study evaluates the various ecclesiological approaches of various confessional traditions that have defined ecclesiology over time. In progression, the study examines contextual ecclesiologies with a focus on three specific cultural geographical environments of Africa, Asia, and Latin America. This is because of the significance that these regions play in the current global shift within Christendom. African ecclesiology has been the centre of focus in an attempt to link all the discussed ecclesiologies with the African Christian thought. The study intends to review the Ubuntu concept and to capture the concept of the humanness of people in the African setting. The study intends to expose the gap in the literature demonstrating that the African conceptual framework can indeed be of use in articulating theology relevant to the African world. The study was keen to evaluate the contribution towards the development and construction of an African ecclesiology using the Ubuntu concept as a remedy to solve ecclesiological problems witnessed in Africa.

Medical models are physical models of human or animal anatomical structures such as skull and heart. Such models are used in simulation and planning of complex surgeries. They can also be utilized for anatomy teaching in medical curriculum. Traditionally, medical models are fabricated by paraffin wax or silicone casting. However, this method is time-consuming, of low quality, and not suitable for personalization. Recently, 3D printing technologies are used to fabricate medical models. Various applications of 3D printed medical models in surgeries and anatomy teaching have been reported, and their advantages over traditional medical models have been well-documented. However, 3D printing of medical models bears some special challenges compared to industrial applications of 3D printing. This paper reviews more than 50 publications on 3D printing of medical models between 2006 and 2016, and discusses knowledge gaps and potential research directions in this field.
