  Abstract In this work, the dosimetric performance of several Commercial Of The Shelf photodiodes was studied. They were tested against gamma rays from a teletherapy source and were characterized with the aim of building a one-dimensional array of dosimeters able to measure the the spatial distribution of dose in a radiotherapy irradiation field. An embedded system comprising an array of 40 photodiodes and its acquisition electronics was built and tested. The dose resolution of each detector was 0.06 cGy and the spatial resolution of the system 0.5 cm.

  Title X-ray micrographic imaging system based on COTS CMOS sensors Type Conference Article
  Year 2017 Publication 2017 Argentine Conference of Micro-Nanoelectronics, Technology and Applications (CAMTA) Abbreviated Journal  
  Volume Issue Pages (down) 1-4  
  Keywords biological techniques; biology computing; CMOS image sensors; image processing equipment; X-ray imaging; X-ray image acquisition; X-ray micrographic imaging system; Commercial Off The Shelf CMOS image sensors; biology; paleontology research; scintillator conversion layers; electronic components inspection; COTS CMOS sensors; electron volt energy 8.0 keV; Photonics; X-ray imaging; Silicon; Attenuation; Detectors; Image sensors; Cmos; Vlsi; X-ray applications; Biomedical imaging; CMOS image sensors  
  Abstract This paper presents the use of Commercial Off The Shelf CMOS image sensors for the acquisition of X-ray images with high spatial resolution. The X-ray images, with application in biology, electronic components inspection or paleontology research, are obtained with 8 keV photons from a Cu tube. The quantum efficiency of the detector is estimated using attenuation lengths of photons in the sensor, and compared to traditional scintillator conversion layers.
