A complete portfolio,
by configuration.
Low-, medium-, and high-energy collimators in parallel-hole, fan-beam, and pinhole configurations — manufactured to customer drawings and configured to OEM energy class, detector format, and program requirements.
Three
energy classes.
Each class is defined by the gamma-ray energy it must stop. Septa thickness, hole length, and material configuration follow.
Low-Energy Collimators
- Range
- ≤ 150 keV
- Isotopes
- ⁹⁹ᵐTc · ¹²³I · ²⁰¹Tl
- Variants
- LEHR · LEHRS · LEUHR
Thin septa and short hole length keep sensitivity high while still absorbing low-energy gammas. The workhorse class for routine SPECT — bone, cardiac, brain, renal.
View LEHRMedium-Energy Collimators
- Range
- 150 – 300 keV
- Isotopes
- ⁶⁷Ga · ¹¹¹In · ¹²³I high-E
- Variants
- MEGP
Thicker septa suppress penetration from higher-energy photons. Required whenever the isotope emits above the LE limit — OctreoScan, gallium imaging, In-WBC.
View MEGPHigh-Energy Collimators
- Range
- ≥ 300 keV
- Isotopes
- ¹³¹I · ⁵¹Cr · therapy pairs
- Variants
- HEGP · HEHR
Thick septa and long hole length absorb hard gammas. The only way to image ¹³¹I quantitatively without massive penetration tails — thyroid carcinoma, dosimetry.

geometries.
Each geometry trades resolution, sensitivity, and field of view for a different clinical question.
Parallel-Hole
The standard general-purpose geometry across LEHR, MEGP, and HEGP energy classes.
ViewFan-Beam
Converging-geometry optics for dedicated brain SPECT and small-organ acquisitions.
ViewPinhole
Magnifying single-aperture optics for the highest spatial resolution on small targets.
ViewRectangular-Hole
Slot-channel geometries built to OEM detector pitch and acquisition mode.
