WebThe principle behind the use of radioactive tracers is that an atom in a chemical compound is replaced by another atom, of the same chemical element. The substituting atom, however, is a radioactive isotope. This process is often called radioactive labeling. WebCancer imaging may refer to: Medical imaging in humans.

Web磁共振成像（ Magnetic resonance imaging ，縮寫： MRI ）是利用核磁共振（ nuclear magnetic resonance ，NMR）原理，依据所释放的能量在物质内部不同结构环境中不同的衰减，通过外加梯度磁场检测所发射出的电磁波，即可得知构成这一物体原子核的位置和种类，据此可以绘制成物体内部的结构图像。 Web藍圖（英語： Blueprint ），港澳地区又称“蓝本”或“蓝纸”，是工程製圖的原图经过描图、晒图和薰图后生成的复制品，因为图纸是蓝色的，所以被称为“蓝图”。 蓝图类似照相用的相紙，可以反复复制新图，而且易于保存，不会模糊，不会掉色，不易玷污。. 在中文语境中，蓝图一詞通常引申为 ... dry ice weed

WebAn X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation.Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3 × 10 16 Hz to 3 × 10 19 Hz) and energies in the range 145 eV to 124 keV.X-ray wavelengths … Chemical imaging (as quantitative – chemical mapping) is the analytical capability to create a visual image of components distribution from simultaneous measurement of spectra and spatial, time information. Hyperspectral imaging measures contiguous spectral bands, as opposed to multispectral … See more Commercially available laboratory-based chemical imaging systems emerged in the early 1990s (ref. 1-5). In addition to economic factors, such as the need for sophisticated electronics and extremely high-end … See more The value of imaging lies in the ability to resolve spatial heterogeneities in solid-state or gel/gel-like samples. Imaging a liquid or even a suspension has limited use as constant sample motion serves to average spatial information, unless ultra-fast recording … See more • E. N. Lewis, P. J. Treado, I. W.
