What is High-Resolution Episcopic Microscopy (HREM)?

High-Resolution Episcopic Microscopy (HREM) is a 3D imaging technique for visualising samples ranging from 1-30mm. Resin mounted samples are stained, then sectioned repeatedly with the remaining block face imaged, creating high-resolution 3D stacks at 1–8-micron voxel resolution.

Advantages of HREM

High-Resolution Episcopic Microscopy (HREM) is a 3D imaging technique of ex-vivo samples providing multiple benefits over conventional 3D techniques such as resolution, cost and more.

Produces 1-8 micron complete voxel resolution over an entire volumetric dataset

Image dense tissue and bone at high contrast without variation

No sample clearing, distortion or interpolation

Capable of imaging up to 25mm samples with micron resolution

Flexibility for a Range of Samples

High-Resolution Episcopic Microscopy (HREM) provides exceptional clarity and resolution, even when imaging denser tissues or tissues with varying opacities.

 

Unlike conventional techniques, eliminate the need for tissue clearing and interpolation, making the imaging process more efficient and convenient. HREM produces high-contrast results, enhancing the visualization of anatomical structures and details.

  • Capable of visualising samples up to 30mm in one capture or greater with scanning

  • Suitable for bone and denser tissue samples

  • High contrast images even in higher density areas

Optical HREM Systems

We offer two main Optical HREM system solutions, available worldwide, offering flexibility in budget and in capture. Each systems can achieve highly detailed 3D image stacks, while allowing the systems to be accessible to more.

OHREM Micro

Micro OHREM Systems offer simple imaging of samples up to 25mm in FOV, featuring single shot optics.

  • 25 x 20 x 20 field of view

  • Simplistic single shot imaging

  • Smaller form factor

Optical HREM Micro 3D imaging system using block face imaging to generate 3D data volumes for dense samples.
Optical HREM Ultra 3D imaging system for scanning of block face imaging for large samples and fluorescence block face imaging.

OHREM Ultra

Ultra OHREM systems offer flexible imaging with XY scanning stages for a FOV up to 60mm with various illumination and optical setups.​

  • ~60 x 60 x 30 field of view, with scanning

  • Choice of upright or zoom optics

  • Ideal for fluorescence applications

'HREM data has allowed the DMDD team to identify nearly 400 different phenotypes in knockout mouse embryos. These range from large-scale organ malformations to the abnormal development of nerves and blood vessels.'

'We are extremely happy with the high quality 3D imaging of our samples. The OHREM system is very flexible, and fully upgradable. We initially only had funds for the single-channel model. However, when we got another grant 12 months later, able to upgrade our system to a 2-channel model with less than 24 hours downtime. The system is very reliable, with virtually no maintenance required. For example, we have used our machine 24/7 for months on end, without any repairs required. In the 2 years we have had the OHREM, we have achieved completely consistent data quality. Aftersales service is friendly, prompt and informative. Chris is also committed to further developing the OHREM technology and engaging with users. For example, he attended a one day workshop organised at University College London in 2019, where users from around the worldwide were able to swap tips and tricks to improve HREM workflows. He made many valuable comments, and was also able to keep us updated on the latest technical developments for the OHREM system.'
