DESCRIPTION: The goal of the study is to improve the resolution of spiral computed tomography of the temporal bone primarily to improve the evaluation of cochlear implants. The first specific aim is to improve CT images. This will be done with computer programming and mathematical de- blurring techniques and with a specialized table transport that has greater longitudinal resolution than that currently available. The second specific aim is to evaluate the images from part one and verify that the images are improved. The deblurring algorithms will be evaluated with mathematical and physical phantoms. Measurements of ossicles and parts of the cochlea will be made on the deblurred scanned images and compared with those obtained from the actual temporal bone specimens. Measurements will also be made of the deblurred images of implanted patients and will be compared to the mechanical specifications and survey of the implants.

描述：本研究的目标是提高 颞骨的螺旋计算机断层扫描主要是为了改善 人工耳蜗植入物的评估。第一个具体目标是改善CT 图像.这将通过计算机编程和数学设计来完成。 模糊技术和专用的表传输， 比目前可用的纵向分辨率更高。第二 具体目标是评估第一部分的图像，并验证 图像得到改善。去模糊算法将通过以下方式进行评估： 数学和物理幻象听小骨及其部分的测量 将在去模糊的扫描图像上制作耳蜗的图像，并进行比较 与实际颞骨标本中获得的结果进行比较。 还将对植入的患者的去模糊图像进行测量。 将与机械规格进行比较， 对植入物的调查。
