ABSTRACT
Imaging cytometry plays an increasingly important role in all fields of biological and medical sciences. It has evolved into a complex and powerful discipline amalgamating image acquisition technologies and quantitative digital image analysis. This chapter presents an overview of the complex and ever-developing landscape of imaging cytometry, highlighting the imaging and quantitative performance of a wide range of available instruments based on their methods of sample illumination and the detection technologies they employ. Each of these technologies has inherent advantages and shortcomings stemming from its design. It is therefore paramount to assess the appropriateness of all of the imaging cytometry options available to determine the optimal choice for specific types of studies. Laser scanning cytometry (LSC), the original imaging cytometry technology, is an attractive choice for analysis of both cellular and tissue specimens. Quantitative performance, flexibility, and the benefits of preserving native sample architecture and avoiding the introduction of artificial signals, particularly in cell-signaling studies and multicolor tissue analysis, are speeding the adoption of LSC and opening up new possibilities for developing sophisticated applications.
