Spatio-temporal analysis of rare events

Spatio-temporal analysis of rare events

Understanding complicated processes require temporal analysis of rare biological events in live studies like cell divisions and the identification of circulating tumor cells. However, since these studies usually rely on isolated static “snapshots”, they tend to be difficult to carry out.

Individual cells within cell populations are not always synchronized, and cell populations are not always homogenous. Visualizing unusual occurrences thus necessitates the systematic, continuous monitoring of multi-dimensional characteristics of the system, the capture of dynamic processes, and the identification of fleeting, sometimes unexpected traits.

Automatic and highly precise identification of particular events of interest, as well as the capacity to swiftly collect and document such events at high resolution, are required for such tracking.

IDEA bio-Medical’s HCS system, WiScan® Hermes, now has a new function for spatial identification and analysis of temporal kinetics of uncommon events. The device initially scans the whole plate and takes photos utilizing low magnifications (2×–10×) in specified time intervals, owing to its rapid image acquisition capabilities, as explained in Figures 1A and B.

Based on the multi-parametric morphological traits or fluorescence properties, this first scan automatically detects items of interest, as depicted in Figure 1C.

Unique characteristics such as a fixed plate (the moving component is the objective) and multi-channel simultaneous imaging are achieved thanks to this rapid scanning capability.

In between scans, a rapid, automatic change of objectives occurs, followed by a second scan in which high magnifications (20×–60×) are recorded only on the selected objects of interest, as shown in Figure 1D, which are spotted and captured with high accuracy due to the rapid focusing scanner high positioning repeatability.

This initial scan is aimed to spot objects of interest at very high speed. C: An automatic multiparametric analysis based on morphological and signal parameters for object mapping is performed at the end of each cycle. D: Second scan acquires images and movies in high magnification (20×–60×) only for objects of interest selected based on the automated analysis. Image Credit: IDEA Bio-Medical Ltd.

WiSCAN® products from IDEA Bio-Medical include Hermes, a true breakthrough in cell imaging systems, and WiSOFT® (the Athena and Minerva packages), a complex image processing algorithmic library controlled by a unique and easy software interface.

For typical complicated applications, researchers can now accomplish high content screening at high throughput rates while maintaining unsurpassed simplicity.

The contradictory demands of producing high-quality images while maintaining high throughput rates are met by employing unique, patented, and patent-pending laser-guided autofocus technologies, an accurate imaging reader, a novel light source modulation method, and fast magnification exchange technologies.
