This is some high tech equipment, so I will try and break todays NR into laymen’s terms


Currently used in today’s scanning instruments are Photo Multiplier Tubes (PMT). The problem with PMT’s is they are made of glass and all components inside are under vacuum. Think of how fragile a light bulb is, this is a throwback to Sir. Graham Bell technology. The vacuum tube is the key design flaw which limits the application of PMT’s. On top of this, vacuum tubes are very unreliable and have short working lifespan.


One example where the vacuum tube of the PMT affects modern technology is in PET scans. Currently the PET and MRI scans are done in separated settings because the high intensity magnets of the MRI destroy the vacuum tube of the PMT.


This is where the MAPD-3N shines because it is a solid state device which is much more durable and can withstand much more rigorous environmental stresses. Thus, allowing the PET and MRI scan to be done in one machine allowing real time scanning. Cutting medical cost significantly and allowing greater scanning precision.


The solid-state design makes MAPD detectors compact and insensitive to high magnetic fields


Key features include:

  • Very high gain (~105–106)
  • High linearity
  • Low operating voltage (~50-100 V)
  • Insensitive to magnetic field
  • All-solid-state compact and extremely reliable design
  • High PDE (15–30%)
  • Fast pulse rise time (~2 ns)
  • Low dark noise (< 1 MHz/mm2)


Applications are:

  • Confocal microscopy
  • Flow cytometry
  • High-energy physics
  • PET/SPECT scanners
  • DNA sequencing
  • LIDAR and environmental monitoring
  • Homeland security


"The MAPD-3N features superior photon detection efficiency, energy and timing resolutions and working gain when compared to existing photo multiplier tubes (PMT). These are on reached mutual agreement critical requirements for PET (positron emission tomography) scanning devices and high energy physics applications. Customers of our solid-state MAPD photo detectors are impressed with the performance and cost advantage offered and we are now in the position to deliver units on a commercial basis."


Zecotek already has licensing agreements, joint ventures and strategic alliances in place with industry leading OEMs and distributors and can now finally start to harvest revenue from their MAPD-3N technology. Even a small piece of the $15 billion medical diagnostics industry is a sizable amount.


Onwards and upwards to gaining more exposure and pushing forward with product commercialization. I see a lot of potential in this company and the MAPD-3N is only the tip of the iceberg. There’s also the 3D technology, LFS scintillation crystals, Integrated Detector Modules, proprietary tunable fibre laser, thin-film wave-guide micro-lasers, and a number of patents still in research and development stage.
