PET/SPECT/CT System

A proprietary gridless positron emission tomography (PET) detector architecture makes the Albira Si the most advanced preclinical PET system on the market. It delivers submillimeter spatial resolution across the full radial field of view (FOV), increasing the high-resolution FOV by an order of magnitude, as compared to traditional PET systems. This capability, combined with high count-rate performance and high PET sensitivity, makes Albira Si the preferred system for dynamic and gated PET in vivo studies. The Albira Si offers all the benefits of integration with single-photon emission tomography (SPECT) and computed tomography (CT). The microCT provides anatomical reference images and attenuation corrections for PET and SPECT imaging. In addition, the Albira Si is compatible with Bruker's multimodal animal beds for cross-platform magnetic resonance imaging (MRI) and optical molecular imaging. Also, the new BioSpec 3T PET/MRI further combines the Albira Si's PET detector technology with superior MRI soft-tissue contrast.

Big Image Data Solution

New microscopy technologies, such as light sheet fluorescence microscopy (LSFM) or clearing methods, allow the imaging of large samples at high resolution or high frame rates. Handling, processing, and analyzing these multiterabyte data sets has become increasingly difficult for scientists in fields such as developmental biology and neuroscience. New tools are needed to overcome these challenges. Therefore, Zeiss has teamed up with Arivis AG to offer complete solutions from initial image acquisition to final results. Arivis Vision4D is a modular software for handling multidimensional (3D+) images of nearly unlimited size. Users can easily import images generated with microscope systems such as Zeiss Lightsheet Z.1, and comfortably stitch and align single images into large comprehensive image stacks. This enables easy assessment and efficient analysis of high resolution brain-mapping experiments or long-term observation of developmental processes in embryos, for example. Zeiss is offering an integrated package worldwide, consisting of Arivis Vision4D software and certified high-performance computer hardware.

Wireless Transmitter/Receiver

The MOVE wireless system is a solution that replaces the existing cables connecting the electrodes and amplifier in electoencephalography (EEG) systems with wireless-based communication. This solution allows the subject to move freely and makes it very suitable for use with a brain-computer interface, neurofeedback, and motor learning. Paradigms that cannot be used with standard cabled EEG systems can now be incorporated into day-to-day research, and normal experiments will become more convenient for the participants. The small, lightweight transmitter box and receiver can be used with virtually any existing amplifier/electrode combination. The transmitter amplifies and digitizes the incoming raw analog signal and sends it to the receiver, where the digital data is converted back to analog. If the data is not received properly, the receiver unit will send a transistor-transistor logic (TTL) pulse marker to the amplifier, and a marker is sent when stable and reliable data reception resumes.

FRAP Imaging Platform

Enabling the easy addition of photomanipulation techniques to imaging platforms, Olympus has launched a new cellFRAP deck system for the popular "open source concept" IX83 and IX73 microscopes. cellFRAP is designed with researchers in mind, providing highly accurate and flexible live-cell photomanipulation with various evaluation options for data presentation needs. Unlike conventional, widefield-based fluorescence recovery after photobleaching (FRAP) systems, Olympus' cellFRAP employs a diffraction-limited laser spot for high-intensity and precise positioning of the bleaching region across the full field of view (FOV). This ensures that photomanipulation reaches every point in the FOV without needing to move the sample. The system's excellent spot quality allows full flexibility in the position and shape of the bleaching region, and enables control of the bleaching area with extreme accuracy. Driven by the Olympus real-time controller, the cellFRAP system achieves an unrivaled short switchover time of only 200 μs between bleach and postbleach acquisition, ensuring detection of the most valuable initial sample response after stimulation.

Neurophysiological Data Analysis Package

NeuroExplorer v5.017 is now available with significant improvements/additions, including enabling maximum benefit when working with and saving neural data files greater than 2 GB, and a new "Find Oscillations" analysis, which identifies episodes of oscillatory activity in the specified frequency band in recorded analog signals. NeuroExplorer is a neurophysiological data analysis package that supports sophisticated analyses and generates a professional presentation of the results. Researchers require the ability to analyze, manipulate, and save such data in huge files. NeuroExplorer launched its new .NEX5 file format last year to meet the industry's growing data demands. This most recent release, v5.017, leverages the increased flexibility of the .NEX5 format not only to analyze and save files greater than 2 GB, but also to save unlimited metadata for the whole file and for every file variable in JavaScript Object Notation (JSON) format.
