The MOSkin Technology consists of an innovative wireless reader and MOSFET or diode based radiation sensor technology that is small in size, tissue equivalent and temperature independent. Major benefits of the MOSkin Technology’s design are its industry leading highly accurate skin or surface dosimetry at a precisely defined and reproducible effective depth of measurement, the transparency of the device to X-ray with minimal radiation beam perturbation, angular independence of the radiation sensors and its ability to also measure dose accurately in small radiation fields.
Current commercially available ‘first-generation’ MOSFET dosimetry/sensor devices use wire bonding and an epoxy bubble to encapsulate the sensor making measurements at equivalent depths difficult to reproduce from one sensor to another, in turn leading to significant uncertainties in skin dosimetry measurement on medical LINACs. The MOSkin Technology can instantaneously (real time) and accurately detect the dosage absorbed by a patient’s skin (including on the sensitive inner tissue of an organ cavity). Its small size, tissue equivalence and temperature independence also minimises treatment disruptions by maximising the accuracy of skin dose detection while reducing operational cost.
Key characteristics of the MOSkin Technology are:
low manufacturing costs;
can be used as a low-cost single use sensor or as a multi-use device;
disposable single use or multiuse (sterilisable);
a dosimeter with real time skin in-vivo dosimetry capability;
small size with no effect on the radiation field;
a highly reproducible build-up layer capable of measuring skin dose which can be altered to simulate other tissue thicknesses;
tissue equivalence above 150 keV photon energies;
not acquired/detected by the c-arm beam;
does not cause any disruption to the beam parameters;
can be retrofitted to most radiation equipment for real time recording and decision making;
ease of use – clinician friendly.
The MOSkin Technology can be classified into two categories of products:
MOSkin – single sensor (for both disposable single-use and multi-use); &
The Magic Plate (consisting of multiple sensor configured arrays).
