Intravital microscopy is a technique that enables you to directly observe the movement of live cells that make up living tissue in vivo. With this technique, it is possible to distinguish an individual cell among a large number of cells in various organs, which is not possible with conventional biomedical imaging technologies such as MRI or CT, and to track the movement of each cell in three dimensions in real-time. IVIM Technology’s All-in-One IntraVital Microscopy (IVM) system is extensively optimized and carefully engineered to provide superb performance in the intravital imaging of live animal models in vivo. It is the world’s first system to fully integrate body temperature regulation and anesthesia into the animal handling stage. The system also includes state-of-the-art live tissue motion compensation for improved image quality, along with ultrafast imaging speeds. The system may be configured for confocal or two/multi-photon microscopy, using either solid-state or femto-second pulsed lasers, respectively.

IVIM Technology was founded on the innovative technology of IntraVital Microscopy (IVM) developed by the Korea Advanced Institute of Technology (KAIST). First founded in 2017, IVIM Technology released the IVM-C and IVM-CM models in 2018. The IVM-M and IVM-MS models were released later in 2019. In mid-2020, a US-based reference site was established at Harvard Medical School in Boston, MA.

Intravital microscopy enables dynamic, 3D, cellular-level imaging of various biological processes in vivo. It enables scientists to directly verify hypothesis derived from ex vivo or in vitro observations in natural physiological in vivo microenvironments.

Using intravital microscopy, in vivo visualizations of gene expression, protein activity, cell trafficking, cell-cell / cell-microenvironment interactions, and various physiological responses to stimuli have been accomplished, providing novel insights, which have been impossible to obtain with conventional static 2D observation of ex vivo or in vitro samples.

However, up until now, individual users have had to improvise the required functions for each of the intravital imaging applications for the various organs with conventional standalone microscopes, which resulted in non-optimal performance for limited applicability.
