Together with technological developments, different methods in anatomic and morphometric studies have been started to be used. In fact, in this study, more than one method was used and the reliability of these methods was presented. This study was performed in the aim of getting 3D model with three dimensional (3D) reconstruction and photogrammetric methods obtained from multidetector computerized tomography (MDCT) images of femur of chinchilla by mimics program, comparing the data of both methods and presenting whether there was a difference between genders as well as left and right sides. For this purpose, 6 chinchillas of both sexes were used. First of all, MDCT images of animals were taken under general anaesthesia and 3D reconstruction was obtained after transferring the data to personal computer as DICOM format. After taking MDCT images, the femurs of the animals killed by the conventional methods were cleaned of muscle and fats by boiling and their 3D models was formed by using images via photo-grammetric methods. The measurements were taken from the models of two methods and volume and surface area of femur were found significant at a level of p<0.05 as a result of statistical processes. According to this, a statistically difference was not found in morphometric measurement values except volume and surface area. Moreover, while a statistical difference was not found between right and left femur of both sexes, a difference was determined between sexes and it was observed that the measurement values of females were higher than males. As a result, since 3D models obtained by both methods had almost same values, it was considered that these methods could be used in anatomic and morphometric studies. Chinchilla (Chinchilla lanigera) Femur'unun Farklı Modelleme Teknikleri ile Morfometrik Değerlendirilmesi Özet Teknolojik gelişmelerle birlikte anatomik ve morfometrik çalışmalarda farklı yöntemler kullanılmaya başlanmıştır. Hatta bir çalışmada birden fazla yöntemle çalışılarak, bu yöntemlerin güvenilirliği ortaya konulmaya çalışılmaktadır. Sunulan bu çalışma şinşilla'nın femur'u üzerinde multidedektör bilgisayarlı tomografi (MDBT) görüntülerinden mimics programı ile elde edilen üç boyutlu (3B) rekonstrüksiyon ve fotogrametrik yöntemlerle elde edilen 3B model üzerinden gerçekleştirerek, her iki yöntem verilerini karşılaştırmak ve cinsiyetler ile sağ ve sol taraf arasında fark olup olmadığını ortaya koymak amacıyla gerçekleştirilmiştir. Bu amaçla her iki cinsiyetten 6'şar şinşilla kullanılmıştır. Önce hayvanların genel anestezi altındayken MDBT görüntüleri çekilerek, veriler DICOM formatında kişisel bilgisayara aktarılarak daha sonra 3B rekonstrüksiyonu yapılmıştır. MDBT görüntüleri alındıktan sonra usulüne göre hayvanların ölümü gerçekleştirilerek, maserasyon yöntemi ile femur elde edilmiştir. Kas ve yağlardan kaynatılarak temizlenen femur'un fotografları çekilerek, görüntülerden fotogrametrik yöntemlerle 3B modeli oluşturulmuştur. Her iki yöntemle oluşturulan modeller üzerinden ölçümler alınmış ve istatistiki iş...
Abstract:The glenohumeral joint is a one of the joints most of which frequently dislocate. Moreover, in this joint various developmental disorders and pathological situations can be seen. The fact that it can perform the widest and the most diverse movements of our body makes the joint surfaces constituting the joint important. Therefore, in this study, surface areas of humeral head and glenoid cavity which form glenohumeral joint of 12 New Zealand rabbits of both sexes were measured, and their proportions to each other were determined on a three dimensional (3D) model obtained via photogrammetric methods. In conclusion, a statistically significant difference was identified between male and female rabbits regarding the joint surfaces constituting glenohumeral joint. Moreover, it was observed that the surface of humeral head was 3 times as large as the surface area of glenoid cavity. It has been suggested that the photogrammetric method that was used and the data that were obtained will shed light on forensic medicine applications and contribute to the information pool in the field of anatomy in veterinary medicine.
