IVIS Spectrum In vivo Imaging System
The IVIS Spectrum is the most versatile and advanced optical animal in vivo imaging system available on the market today. An optimized set of high-efficiency filters and spectral unmixing algorithms lets you take full advantage of bioluminescent and fluorescent reporters across the blue to near-infrared wavelength region. It also offers 3D tomography for both fluorescent and bioluminescent reporters that can be analyzed in an anatomical context using the Digital Mouse Atlas.
For advanced fluorescence imaging, the IVIS Spectrum has the capability to use either trans-illumination (from the bottom) or epi-illumination (from the top) to illuminate in vivo fluorescent sources. 3D diffuse fluorescence tomography can be performed to determine source localization and concentration using the combination of structured light and trans-illumination fluorescent images. The instrument is equipped with 10 narrow-band excitation filters (30 nm bandwidth) and 18 narrow-band emission filters (20 nm bandwidth) that assist in significantly reducing autofluorescence by the spectral scanning of filters and the use of spectral unmixing algorithms. In addition, the spectral unmixing tools allow the researcher to separate signals from multiple fluorescent reporters within the same animal.

Vevo 2100 Ultra High-Frequency Ultrasound
Ultra High-Frequency ultrasound for small animal research has linear array technology, ideal for cardiovascular and cancer imaging.
The MicroScan transducers provide increased frame rates, superb contrast, unrivaled resolution and a wider field of view.
Available Imaging options for the Vevo 2100 system:
- Super B-Mode (2D) imaging for anatomical visualization and quantification, with an enhanced temporal resolution with frame rates up to 740 fps (in 2D for a 4x4 mm FOV) , and enhanced image uniformity with multiple focal zones.
- M-Mode for visualization and quantification of wall motion in cardiovascular research, single line acquisition allows for the very high-temporal (1000fps) resolution necessary for the analysis of LV function.
- Anatomical M-Mode for adjustable anatomical orientation in reconstructed M-Mode imaging; the software automatically optimizes the field of view for maximum frame rate.
- Pulsed-Wave Doppler Mode (PW) for quantification of blood flow.
- Color Doppler Mode for detection of blood vessels including flow directional information and mean velocities; as well as for identification of small vessels not visible in B-Mode.
- Power Doppler Mode for detection and quantification of blood flow in small vessels not visible in B-Mode; increased frame rates allow for significantly faster data acquisition.
- Tissue Doppler Mode for quantification of myocardial tissue movement; for example in assessing diastolic dysfunction.
- Vevo MicroMarker Nonlinear Contrast Agent Imaging - for quantification of relative perfusion & molecular expression of endothelial cell surface markers; enhanced sensitivity to Vevo MicroMarker contrast agents as linear tissue signal is suppressed.
- 3D-Mode Imaging for anatomical and vascular visualization, when combined with either B-Mode, Power Doppler Mode, or Nonlinear Contract Imaging; allows for quantification of volume and vascularity within a defined anatomical structure.
- Digital RF-Mode for the acquisition and exportation of radio frequency (RF) data in digital format for further analysis; fullscreen acquisition provides a complete data set for more comprehensive analysis and tissue characterization.
