Biomedical Imaging and Therapy

Overview

Biomedical imaging and Therapy facility is a set of two beamlines designed to support a wide variety of programs in the life sciences by providing outstanding possibilities for pre-clinical and biomedical imaging. The versatility of BMIT imaging stations also allows to study various problems of material science, energy, environment, cultural heritage, and others scientific areas.

BMIT bending magnet beamline generates X-rays in the energy range 12.6-40 keV which is optimal for imaging of lightweight materials and of small animals such as mice. Owing to the exceptional stability of the beam, crystal-based imaging modalities such as K-edge spectral imaging and analyzer crystal based imaging can be employed. Access to the white beam enables imaging with high spatio-temporal resolution (CT snapshot in less than 10 sec) and high throughput screening.

Please discuss details of your proposal with the beamline scientist prior to submitting your proposal.
