Forensic 3D/CAD supported photogrammetry (FPHG) is a method of recording and documenting the surface of small objects, thus enabling a three-dimensional image of these objects in virtual space. With this representation on the computer screen the course of forensically relevant events can be reconstructed. The procedure allows for examining patterned injuries of skin, soft tissue or bones for matching potentially incriminated instruments in shape, size and angle.3D recording of objects to be examined requires taking series of photographs. A computer system then calculates the position in space of certain points on the surface of the objects and subsequently produces 3D data models of the objects. Using a 3D/CAD program these data models are used to generate graphic true-to-object volume models. The objects in question can then be moved against each other arbitrarily on the screen-depending on the questions to be answered-in order to compare them and possibly establish their congruence. This article covers the state of the art in FPHG procedures in the form of a step-by-step instruction. It also illustrates the wide range of FPHG applications.
The evaluation of a link between two heroin seizures using a descriptive method is presented. It is based on the measure of the angles between two chromatograms assimilated to vectors, and interpreted using a continuous approach based on the likelihood ratio of Bayes' theorem. A complete evaluation model thus avoids the drawbacks of decision thresholds used until now to establish a link. Validation is obtained through tests and simulation methods.
Malpractice and medical liability have been introduced into Greek reality over the last decade. Forensic sciences hold a key role in the investigation of medical liability cases. Along these lines, the medical examiner stands between colleagues and lawyers, who have divergent intentions in the investigation of such cases. This article offers an overview of the rapidly changing reality in Greece and approaches medical liability from the doctor's viewpoint. The role of forensic science and the medical examiner is portrayed, along with the emerging difficulties in the investigation of medical liability cases. Also attempted is an interpretation of the crisis phenomena that are very often seen between doctors and lawyers. However, the intent of this article is to search for ways to turn competition and tension between medical and law professionals into cooperation and understanding for the best interest for both professions and, more importantly, for the community.
