Nuclear medicine relies heavily on medical collimators, beam-limiting devices that shape the beam of radiation emerging from a machine and optimize the radiographic imaging. Medical collimators limit the maximum field size of the beam and restrict rays from the source so each point in the image corresponds to a unique point in the source, preventing unnecessary exposure of the anatomy outside the area of interest and improving image quality and contrast by producing less scatter radiation from those areas.

Medical collimators are ideal for low-energy treatments like proton therapy, where they can minimize radiation risk to the patient by reducing the overall integral dose of radiation.

Common types of medical collimators include:

• Parallel hole
• Converging
• Diverging
• Pinhole
• Manual and selectable x-ray
• Low, medium, and high energy

With DEX, you can keep your medical collimators operating at peak performance and save thousands of dollars over purchasing new. Leveraging more than 40 years of experience supporting the medical field, a global database of thousands of suppliers, and best-in-class engineering services, DEX can:

• Complete the component-level repair and replacement that’s nearly impossible in the field
• Test components on fully functioning systems and adjust them to unique specifications
• Calibrate your equipment
• Conduct software and hardware repairs
• Test and replace faulty control boards and batteries

By repairing, refurbishing, or replacing critical components such as power controller area network cables, cassette sensing trays, and assemblies, DEX helps reduce downtime and extend the life of your medical collimator at a fraction of the cost.

DEX performs services and procures parts for even out-of-production and hard-to-find collimator models from OEMs like:

• Siemens
• GE
• Picker
• Philips
• Ralco
• Machlett
• Eureka
• Huestis

Top Industry Use Cases for Collimators

By narrowing and shaping beams of radiation or light, collimators can provide precision for tasks like image resolution, device calibration, and radiation control. This makes them ideal for a wide range of industry use cases, such as:

• Nuclear power stations
• Optical device calibration
• Scintillation imaging
• Radionuclide imaging
• Planar scintigraphy for electronic detection medical imaging
• Radiography and fluoroscopy projection imaging
• Military
