“…On these scans the different anatomic parts are distinguished by segmentation performed in 3D Slicer using threshold based semi-automatic method. After the pixelwise segmentation, the obtained surface meshes are smoothed and corrected by VCG reconstruction [10] in Meshlab [11]. Smoothed surface models are converted to 3D CAD geometry in ANSYS ® SpaceClaim (Release 18.0, ANSYS, Inc., PA, USA) and the obtained geometry is imported to ANSYS ® Workbench (Release 18.0, ANSYS, Inc., PA, USA) where the finite element models are developed.…”

Decompressive Craniectomy (DC) is a neurosurgical procedure which is often applied to decrease the intracranial pressure (ICP), even if its optimal execution in terms of the size and location of the skull opening is not known. The current research focuses on DC from a biomechanical perspective. A finite element (FE) modelling strategy is applied where patient-specific head models are developed. These numerical models are used to perform virtual experiments where DC is simulated several times with skull openings having different size and location. During the simulations ICP, stress and strain distributions in the brain tissue are monitored in the function of the skull opening details. In the knowledge of these objective functions suggestions could be made regarding the applied optimization procedure which can lead to the identification of optimal DC scenarios in the future.

“…In these cases, the illumination conditions are not important. TLS has shown promising results, even in complex spaces and structures, as demonstrated by Fernández-Palacios et al (2013), Nabil et al, (2013), Lima andVergauwen (2018), Echeverria et al (2019) and Mozas et al 2020 in several Egyptian tombs. The presence of narrow spaces or occlusions will suggest the addition of more scanning stations to cover the structure completely in contrast to the low increment of time required by each scan.…”

“…A more detailed analysis of the advantages and problems of CRP and TLS in cultural heritage applications was conducted by Hassani et al (2015). Several studies have shown that the integration of both techniques can improve results (Kadobayashi et al, 2004;Ahmon, 2004;Alshawabkeh, Haala, 2004;Guarnieri et al, 2006;Grussenmeyer et al, 2008;Lerma et al, 2010;Fernández-Palacios et al, 2013;Nabil et al, 2013;Lima, Vergauwen, 2018). In general, the integration of CRP and TLS has shown good results because it takes advantage of the particular characteristics of each technique.…”

Abstract. This study describes the methodology carried out and the main results achieved when using photogrammetry and Terrestrial Laser Scanning (TLS) to obtain 3D models of the evolution of archaeological works in Egyptian tombs. More concretely, the study was performed in the exterior zone of the QH34 set of tombs located in the necropolis of Qubbet el-Hawa (Aswan, Egypt). The necropolis is composed of tens of rock-cut tombs located in a medium-size hill situated on a bank of the Nile River. The QH34 zone concentrates a great quantity of tombs from several periods of ancient Egypt. The area of study is situated on a horizontal platform of the terrain of about 300 m2. Thanks to the particular geology of this zone, with a fracture that caused the collapse of part of the rocks, much of these tombs have remained intact because the remains of the collapsed terrain hid their entrances. The archaeological works were carried out during two periods (2018 and 2019 campaigns). The main goal of this study was to model the evolution of these works using several geomatic techniques and obtaining several 3D models of the terrain and burial elements to document the previous, intermediate and final status and to analyse the archaeological works undertaken. In addition, a reduced time was demanded for the acquisition of data. The methodology developed has demonstrated its viability for performing multi-temporal studies in order to document the evolution of the excavation, providing a wide and reliable set of geomatic products.

“…were applied. As examples, there are applications in caves (Lerma et al, 2010), rock-cut tombs (Nabil et al, 2013) and historical buildings (Guarnieri et al, 2006). In general, the main issue in this type of studies is related to the presence of reduced and narrow spaces.…”

“…In this sense, several studies have shown smart solutions based on the use of fisheye lenses (Covas et al, 2015;Perfetti et al, 2017) or low-weight cameras located on masts (Fiorillo et al, 2016;José Luis et al, 2019). In the case of studies of tombs, several applications have been developed using both photogrammetry (Angelini et al, 2016;José Luis et al, 2019) and TLS (Ahmon, 2004;Fernández-Palacios et al, 2013;Nabil et al, 2013;Lima, Vergauwen, 2018;Echeverria et al, 2019). Considering the current possibilities of the geomatic techniques, in this study we describe the method carried out and the results obtained after their application to several funerary complexes (QH31, QH32 and QH33) in the Necropolis of Qubbet el Hawa (Aswan, Egypt).…”

Abstract. This paper describes the methodology employed to obtain 3D models of three funerary complexes (QH31, QH32 and QH33) of the Necropolis of Qubbet el Hawa (Aswan, Egypt) and the main results obtained. These rock-cut tombs are adjacent structures defined by complex geometries such as chambers, corridors and vertical shafts. The main goal of this study was to discover the spatial relationships between them and obtain a complete 3D model. In addition, some models with realistic textures of the burial chambers were demanded in order to analyse archaeological, architectural and geological aspects. The methodology was based on the use of Terrestrial Laser Scanning and Close Range Photogrammetry. In general, both techniques were developed in parallel for each tomb. Some elements presented difficulties because of their reduced dimensions, the presence of vertical falls, some objects stored in the tombs that generated occlusions of some walls, coincidence of other workers, poor illumination conditions, etc. The results included three complete 3D models obtained without texture and some parts of interest obtained with real textures. All models were merged into a global 3D model. The information extracted from this product has helped architects and archaeologists to contrast their premises about the spatial behaviour of the tombs. The results have also allowed the obtaining of the first 3D documentation of these tombs under the same reference system, allowing them to be studied completely. This information is very important for documentation purposes but also to understand the spatial behaviour of these structures and the excavation processes developed by ancient Egyptians 4000 years ago.
