Deep learning for pneumonia detection on chest x-rays

Recent advances in technology have immensely increased available computing power and data storage capacity . At the same time, digitisation of previously analog aspects of business and life, has made vast amounts of data available for analysis. Every digital log entry can somehow be collected and analysed. This is the ideal breeding ground for machine learning!

Calculation of radiation dose to a material by using an ionization chamber

Dose deposition to a medium may only be directly measured by the method of calorimetry. However, this is not what we do in practice. What is usually done is that we use an ionization chamber of some kind to measure exposure and then apply a series of correction factors in order to derive dose values corresponding to the measured exposure.
