In the past decade, powerful new X-ray scans and three-dimensional computer models have transformed the analysis of bones, teeth, and shells.

过去十年间，新型X光扫描和计算机三维模型已经改变了人们对骨骸、牙齿和外壳的分析方式。

Ct scan is like an X-ray, but it USES multiple images to build up a more detailed, three-dimensional (3-d) picture of your brain.

CT扫描是像X光，但它使用多张图片，建立一个更详细的，三维(3 -丁)你的大脑的图片。

Using a combination of modern physics tools--including three-dimensional, high-resolution X-ray, radiocarbon dating with accelerator mass spectrometry, and infrared spectroscopy--the researchers analysed the tooth to determine the age and composition of a resinous filling detected inside.

It took advantage of X-ray crystallography that charted the precise three-dimensional structure of how Gleevec binds to Bcr-Abl.

The specimen is then rotated on a mechanised platform as it is exposed to the X-ray beam, in order to build up a three-dimensional picture.
