ANT334H5 Lecture Notes - Lecture 6: Lordosis, Forensic Anthropology, Biological Anthropology
Document Summary
Current trend is ct and mri: manipulate image, better resolution, 3d. Biological anthropologists use imaging: growth and development process of aging and age estimation, pathology anything not normal to skeleton. Forensic anthropology: survey know what to expect, personal identification (radiograph, trauma/foreign objects. Strikes sensitive film: film turns dark when developed, object absorbs radiation to varying degrees, absorption depends on composition, film appears gray to white when developed. Works well on bones as bone is dense tissue. Views: ap, anteroposterior, x-ray enters anterior surface and exits posterior, lateral, x-ray enters left side and exits right, oblique on an angle, lordotic leaning back. Orientation: looking at patient, r marker, patient"s right side, many radiographs are now digital and thus there will be less confusion with orientation, chest x-ray, use heart side, left side of ap radiographs. Structures: radiodense, more absorption, appears white, e. g. bone, cartilage, radiolucent, less absorption, appears darker gray through black, soft tissue, e. g. soft tissue, air chambers.
