![]() ![]() These RCFs are used for beam position alignment, measuring beam slice-width or the surface skin-dose in interventional procedures, among others 4, 5. Regarding to the latter, radiochromic films (RCFs) are currently the gold‒standard passive detectors for the measurement of dose distribution in radiology and radiotherapy 1, 2, 3. On the other hand, it ensures that the prescribed dose is properly delivered to the patient at the targeted location. beam output verification) within the specific conditions recommended by international protocols. On the one hand, it permits the validation of the machine’s effective operation for dose delivery (i.e. In the case of radiotherapy, the measurement of the radiation dose has a twofold function. ![]() For example, in radioprotection, the continuous monitoring of radiation doses is necessary to guarantee the safety and security of the people, and to adapt the protection tools to it. A precise determination of the dose locally delivered to an object is of interest in multiple fields. The effects of ionizing radiations depend on the type of radiations and the dose delivered, which is the energy deposited locally by unit of mass. Irradiation in medicine, chemistry or security is the process by which an object is exposed to ionizing radiation. We point to develop a portable dosimetry tool delivering dose maps in real time to improve the clinical application of radiochromic films. Further developments are ongoing to create an advanced 16 × 16 LDRs system covering 1.6 cm × 1.6 cm with a 1 mm of spatial resolution. To the best of our knowledge, this is the first MOEM sensor for radiotherapy. Results show the feasibility of using this system for dose evaluations. Results were compared with Monte Carlo simulations and very good agreement was found. ![]() We obtained similar results than with a standard method (e.g. We present the first tests performed in an X-ray machine and 137Cs source with that array by using Gafchromic EBT3 films. The proposed system is based on a 5 × 10 matrix of photodetectors controlled by both in-house electronic circuit and graphical user interface, which enables optical measurements directly. This work presents the validation of a new Opto‒Electro-Mechanical (MOEM) system consisting of a matrix of photodetectors for two-dimensional dosimetry evaluation with radiochromic films. ![]()
