Single Electron Events in TEM

Single Electron Events (SEE) have been used to quantify the point spread function of several cameras for Transmission Electron Microscopy (TEM). The spatial resolution is measured by the Single Electron Modulation Transfer Function (MTFSEE) compared with the MTF generated by standard knife edge experiment. In addition, the sensitivity of the camera as a function of high tension has been measured, showing an excellent Signal-to-Noise Ratio (SNR) from 300 kV down to 8 kV.

Pixel Size & Sensitivity

The number of pixels in image sensors is of central importance for the image quality. There is a general tendency towards higher resolutions, because they are associated with higher information content. Higher resolutions mean smaller pixels. The sensitivity of the pixels is another important feature (characteristic) of an image sensor. Larger pixel image sensors are said to be more sensitive than smaller pixel sensors. moreJul. 11, 2012

Scientific Image Data Visualization

Scientific data visualization, analysis and mining are among the key processes used in life sciences. Together with a vast array of novel imaging techniques, they give the researchers detailed insights into the complex relationships that exist within living cells. With an ever-increasing amount of multi-dimensional image data, the complex task of extracting and understanding multifaceted biological information should be aided by advanced image analysis software tools. Such tools must be capable of guiding and intuitively aiding their users throughout the image analysis process. Visualization and understanding of complex images of single molecules and organelles as well as whole cells, tissues and organs is a challenging tour de force that can benefit from advanced software systems tailored to provide the best qualitative and quantitative representation of image data.
