We have created an atlas of the temporal bone which is an educational tool for studying the normal anatomy of the petrous bone based on an MDCT exam of the axial and coronal of the ear and petrous bone. Anatomical structures are visible as interactive labelled images.
An axial and coronal bone multislice computed tomographic imaging of the temporal bone was performed on a normal subject.
Data and DICOM images archived on the PACS (Picture Archiving and Communicating System) were processed and exported as JPEG images. Adobe Flash and Adobe Photoshop allowed us to develop an atlas-based application with suitable functionality and user interface for exploration of the temporal bone and skull base.
Anatomical structures have been labelled according to the Terminologia Anatomica.
This module is a comprehensive and affordable learning tool for residents and medical students and especially for neuro-radiologists and otolaryngologists.
It provides images in the axial and coronal planes, allowing the user to review and learn anatomy interactively. Images are labelled, providing a useful teaching resource. The test mode allows an evaluation of user progress.
The horizontal menu allows access to the groups of anatomical structures:
As the cursor is moved over an anatomic area, that area is labelled and highlighted: this allows to the viewer to study the bones of the skull base such as the petrous part of the temporal bone.
The CT is a particularly powerful exam for studying the five bony parts of the T-bone:
The vertical left menu provides cross references with axial, coronal and sagittal images of the T-bone, with anatomical graphics based on a three dimensional (3D) model.
