“…Thus Cone Beam Computed Tomography (CBCT) is in period of its rapid development, especially in dental practice. Its principles derive from early 60s-70s (Hounsfield, 1973) and continue in palaeoanthropological studies as well (Uldin, 2017). It should be mentioned that cone beam computed tomography produces high quality 3D images of bone structures without high exposure of patients to x-rays.…”

Abstract. Improvements of existing and development of new non-contact measurement techniques, especially for surfaces of complex spatial shape, allow involvement of various disciplines into advanced technological reality. These improvements have two major directions. The first, being more obvious, refers to introduction of accurate digital 3D images in spheres where real objects have become subjects of traditional study, techniques or manufacturing technologies. The other direction deals with substantial methodological improvements, as they become possible only with introduction of the above-mentioned techniques. Among such is the division of physical anthropology, of dentistry and other disciplines related to dental studies, – odontometry, or measurements of teeth. Traditional odontometry, by turning into automated digital odontometry, becomes a method of accurate and objective morphological assessments in dentistry and anthropology, including palaeoanthropology. As a new method, automated digital odontometry requires interpretations of dental morphology (applicable in digital techniques), accurate 3D images of teeth and software based on 3D and 2D image analysis suitable for automated measurements. The mentioned factors are particularly important for this method due to its inapplicability on real objects. Thus various approaches to obtaining digital images are discussed in the context of their quality and conformity with the studied material and odontometric technique, which currently includes automated orientation algorithms setting locations for principal morphological structures and measurement algorithms themselves, likewise functioning in an automated mode.

“…Aside from being non-invasive, these techniques have the additional advantages of being fast in acquiring craniofacial surface images, allowing images to be archived and avoiding errors in measurement that occur when 3D surfaces are represented in 2D. The investigations are also repeatable and verifiable [14,15,31].…”

Virtual anthropology? Reliability of three-dimensional photogrammetry as a forensic anthropology measurement and documentation technique

Establishing the identity of unknown remains is a vital role of forensic anthropology. While establishing identity is generally straightforward due to conventional methods of identification like DNA analysis, sometimes these methods are not applicable in the case of remains that are heavily skeletonized, severely decomposed or severely charred. In such instances, a forensic anthropologist will be called upon. The role of the forensic anthropologist is to aid in the identification of remains when conventional methods such as DNA and fingerprinting are not applicable. They may also be required to collaborate with other experts like forensic odontologists in order to attain a positive identification. A number of methods are available to the anthropologist that can aid in achieving identification: comparative radiography, nonimaged records, craniofacial superimposition, dental comparison and craniofacial reconstruction. All the methods except nonimaged records require imaging, either in two dimensions or three dimensions. Three-dimensional imaging is quickly becoming a vital tool for reconstruction, comparison, and analysis in forensic science. It has found applications in road accident reconstruction, facial reconstruction, comparison of patterned injuries to the injury-inflicting instruments, and anthropometry. The main three-dimensional imaging methods utilized in the forensic field are photogrammetry, laser scanning and radiological scanning (computed tomography (CT) and magnetic resonance imaging (MRI)), with forensic three-dimensional/computer aided design (3D/CAD)-supported photogrammetry being the method that is primarily used due to its low cost, rapid results, does not need expertise to operate, has no radiation risks and, above all, the record is permanent. Regardless of this, CT and MRI are more established methods and are widely used in a variety of industries 4 The purpose of this paper is to compare and contrast the three-dimensional imaging methods currently employed in forensic science on the basis of reliability, reproducibility, and accuracy; with an ultimate aim of validating photogrammetry as an analytical and documentation method of forensic science.

“…Son yıllarda, non-invaziv görüntüleme teknolojileri, özellikle radyolojik üç boyutlu görüntüleme yöntemlerinin kullanımı biyoloji, paleontoloji, biyolojik antropoloji, arkeoloji, adli bilimler ve malzeme bilimi dâhil olmak üzere birçok bilim alanına katkıda bulunmuştur (Uldin, 2017). Özellikle biyolojik antropoloji, fosil kalıntılarının incelenmesi ve iskelet kalıntılarının analizi için modern görüntüleme teknolojilerinden önemli ölçüde yararlanmış ve bu alanda yayınlanan çalışmaların sayısı son yıllarda hızla artmıştır.…”

New scientific discoveries and directions have provided significant progress within the field of imaging technologies in recent years. One of the most important of these new scientific discoveries was the use of radiological imaging methods discovered in the late 19th and early 20th centuries in anthropological research. These methods enable the examination of both internal and external properties of an object by creating accurate virtual representations of the examined sample without destroying it. These developments in information technologies have created new research opportunities for anthropological studies and a new field called virtual anthropology has developed. Therefore, this article reviews the basic uses of various non-invasive imaging methods, such as conventional radiography, computed tomography, or micro-CT, as well as magnetic resonance imaging and ultrasound. The aim of this review is to discuss the benefit of using these imaging modalities for anthropological studies.
