Digital image processing for image quantification in ion microscope analysis

A versatile video tape system for storage and selective retrieval of ion images for digital acquisition and processing

“…In this system, ion images are directly digitized (on-line) from the Cameca IMS-3f ion microanalyzer and immediately stored on magnetic disk for later manipulation. This allows for high-speed acquisition of images relative to older methods that rely on digitization and calibration of photographic film by photomicrodensitometry (14)(15)(16)(17). However, a direct result of this on-line process is the loss of a great deal of data, due to the finite digital storage space available and the very large storage size requirements of digital images.…”

Spatial enhancement and restoration of chemical images from secondary ion mass spectrometry and ion scattering spectrometry

“…Table I. Origin of Transient LEI Pulse Derived from Steady-State Data (10) time after aspiration (arbitrary units) signal for indium should reach a maximum and then return to a value which corresponds to the steady-state signal for indium with a potassium matrix as the experiment suggested.…”

Acquisition and quantification of ion images with a camera-based detection system and classical quantification algorithms

“…Despite this promising evolution, the progress here is hampered by the quantification problems. Commonly used methods, such as the local thermodynamic equilibrium (LTE) model, the sensitivity factor (SF) method [16][17][18], the matrix ion species ratio (MISR) method [19,20], and ion implantation [21] have all been applied with varying degrees of success to convert the ion images from intensity space to concentration space [2,3,9,[22][23][24][25][26][27].…”
