VECTor: simultaneous molecular imaging without compromise

Biology doesn’t stand still, and neither should your imaging system.

VECTor is designed for researchers who want maximum freedom in tracer and isotope choice, today and in the future. With true broadband molecular imaging capabilities, VECTor lets you work across a wide range of energies and isotope types, from established tracers to emerging and yet-to-be-imagined compounds. Whether you’re developing new radiotracers, exploring novel theranostic strategies, or pushing the boundaries of molecular imaging, VECTor gives you the flexibility to design studies around biology, not hardware limitations.

Simultaneous PET and SPECT imaging

Capture aligned molecular insight in space and time.

VECTor uniquely enables simultaneous PET and SPECT imaging within a single acquisition, allowing researchers to image tracers separately or together under identical physiological conditions. This eliminates uncertainty caused by sequential scans or inter-animal variability.

Benefits include:
  • EDirect comparison of multiple molecular pathways in one subject
  • EAligned spatial and temporal datasets
  • EReduced experimental variability
  • EFlexible acquisition without switching systems
  • EUltra-high-resolution molecular imaging
  • EResolve small structures and subtle signals with confidence
VECTor builds on MILabs’ ultra-high resolution SPECT and PET technologies to deliver sub-millimeter molecular imaging across modalities. Uniform resolution and high sensitivity enable detailed visualization of heterogeneous tissues and small anatomical features.

The stationary detector design supports fast, dynamic imaging, allowing researchers to follow tracer kinetics and biological processes in real time.

Advanced theranostic and high-energy imaging

Directly image therapeutic isotopes.
VECTor supports quantitative imaging of high-energy therapeutic and theranostic isotopes, including alpha, beta, and Auger-electron emitters. This allows direct visualization of therapeutic agents without relying on surrogate tracers. By maintaining resolution and quantification at higher energies, VECTor supports advanced dosimetry research, tracer development, and translational workflows as isotope strategies continue to evolve.
Advanced theranostic and high-energy imaging

Integrated PET, SPECT, and CT in one workflow

Combine molecular and anatomical insight seamlessly.
VECTor systems can be configured with integrated high-resolution CT, providing precise anatomical context alongside molecular data. This enables accurate localization, improved quantification, and aligned datasets within a single imaging session. Low-dose, high-speed CT supports longitudinal studies while maintaining throughput and animal welfare.

Dual-isotope imaging allows in vivo immunohistochemistry using radiolabelled antibodies in tumours

Name and title - Prof. B. Cornelissen, PhD, Oncology, University of Oxford, UK

“We have demonstrated that the use of dual-isotope VECTor PET/SPECT/CT Imaging of ⁸⁹Zr/¹¹¹In overcomes the issue of nonspecific antibody in tumors. It enables true quantification of epitope expression levels, and allows non-invasive in vivo immunohistochemistry.”
