Sectional anatomy of human brain is useful to examine the diseased brain as well as normal brain. However, intracerebral reference points for the axial, sagittal, and coronal planes of brain have not been standardized in anatomical sections or radiological images. We made 2,343 serially-sectioned images of a cadaver head with 0.1 mm intervals, 0.1 mm pixel(More)
The interpretation of computed tomographs (CTs) and magnetic resonance images (MRIs) to diagnose clinical conditions requires basic knowledge of sectional anatomy. Sectional anatomy has traditionally been taught using sectioned cadavers, atlases, and/or computer software. The computer software commonly used for this subject is practical and efficient for(More)
Sectioned images of cadavers enable creation of realistic three-dimensional (3D) models. In order to build a 3D model of a structure, the structure has to be outlined in the sectioned images. The outlining process is time consuming; therefore, users want to be provided with outlined images. The more detailed structures are outlined, the greater potential(More)
Authors had prepared the high-quality sectioned images of a cadaver head. For the delineation of each cerebral gyrus, three-dimensional model of the same brain was required. The purpose of this study was to develop the segmentation protocol of cerebral gyri by referring to the three-dimensional model on the personal computer. From the 114 sectioned images(More)
The structure of the ear, which intervenes between gross anatomy and histology in size, can be best understood by means of three-dimensional (3D) surface models on a computer. Furthermore, surface models are the source of interactive simulation for clinical trials, such as tympanoplasty. The objective of this research was to elaborate the surface models of(More)
In our previous research, we created state-of-the-art sectioned images, color-coded images, and surface models of the human ear. Our ear data would be more beneficial and informative if they were more easily accessible. Therefore, the purpose of this study was to distribute the browsing software and the PDF file in which ear images are to be readily(More)
The purpose of this case report is to report a rare vascular variation in the upper limbs because of its clinical importance and embryological implication. During the educational dissection of a 73-year-old Korean male cadaver`s right upper limb, we found a variant branch which is originated from the thoracoacromial artery. The variant branch from the(More)
In medicine, the neuroanatomy of the oculomotor (III), trochlear (IV), and abducens nerves (VI) is learned essentially by cadaver dissection, histological specimens, and MRI. However, these methods have many limitations and it is necessary to compensate for the insufficiencies of previous methods. The aim of this research was to present sectioned images and(More)
The objective of this research was to produce high-quality sectioned images of a whole dog which can be used to create sectional anatomy atlases and three-dimensional (3D) models. A year old female beagle was sacrificed by potassium chloride injection and frozen. The frozen dog was then serially ground using a cryomacrotome. Sectioned surfaces were(More)
Objective: Cadaver's sectioned images with high resolution and real color could be used as the source of realistic three-dimensional images. If the sectioned images are registered to a patient's MRIs, three-dimensional images with high resolution and real color that fit the patient, can be produced; the three-dimensional images enable realistic virtual(More)
