OEM Collimators,
manufactured to drawing.
Custom collimator assemblies for SPECT and gamma-camera systems — built to the customer's drawing, BOM, and inspection criteria. Programs span new platform development, current-generation supply, and ongoing service replacement for legacy installations.

Geometry
portfolio.
Four standard geometries, each engineered for a different clinical question. Channel geometry, septa, and interface are manufactured to the customer drawing.
Identical channels perpendicular to the detector. Only true-normal photons survive the septa; the image is geometrically faithful at 1:1.
Whole-body bone, lung perfusion, renal, brain SPECT.
Parallel-Hole
The general-purpose SPECT geometry. Low, medium, and high energy across the diagnostic isotope range.
Channels converge toward a focal line; the projection magnifies in one axis while preserving 1:1 in the other — trading field of view for detail.
Brain SPECT (DaTscan, perfusion), small-organ studies.
Fan-Beam
Converging-geometry optics for brain SPECT and small-organ acquisitions. To customer focal length.
Photons cross at a single aperture and form an inverted image on the detector. Magnification is geometric — set by focal and object distance.
Thyroid, parathyroid, sentinel node, paediatric SPECT.
Pinhole
Magnifying single-aperture optics for the highest spatial resolution on small targets.
Rectangular-section channels perpendicular to the detector. The long axis raises geometric efficiency for slot-shaped targets; the short axis preserves resolution.
Whole-body planar, lymphoscintigraphy, high-throughput.
Rectangular-Hole
Slot-channel geometries built to OEM detector pitch. High-sensitivity acquisitions.
Energy
classes.
Three principal classes, each defined by the gamma-ray energy it must stop. Customer terminology varies (LEHR, LEHRS, LEUHR, MEGP, MELP, HEGP, HEHR): underneath, three energy bands cover the full diagnostic and therapeutic isotope range.
| Class | Energy | Isotopes | Clinical use |
|---|---|---|---|
| LELow energy · LEHR / LEHRS / LEUHR / LEGP | 30 – 200 keV | ⁹⁹ᵐTc · ²⁰¹Tl ¹²³I · ¹¹¹In | General-purpose SPECT — bone, lung perfusion, brain, renal, cardiac. |
| MEMedium energy · MEGP / MELP | 200 – 400 keV | ⁶⁷Ga · ¹¹¹In ¹⁷⁷Lu · ¹²³I high-energy | Therapy monitoring, sentinel-node localisation, and infection imaging. |
| HEHigh energy · HEGP / HEHR | 350 – 600 keV | ¹³¹I · ¹⁸F theranostic isotopes | Post-therapy imaging, ¹³¹I scans, and emerging theranostic protocols. |
