Content
The course will be organized around three main pillars
- Advanced Statistics in Medical Physics: statistics are heavily used in medicine in general and in medical physics in particular. This includes statistical significance of laboratory and clinical experiments; quantification of risk; estimation and propagation of uncertainties (type A and type B uncertainties); probabilistic problem solving.
- Monte Carlo techniques. Monte Carlo engines are often used as black box in clinical practice and R&D. The goal is to provide insights in the theoretical grounds of Monte Carlo simulations and also in the practical specificities of modern implementations. This includes: random number generation; sampling techniques (inverse transform, rejection technique); variance reduction; statistical error estimation (direct or batch technique); problem definition (geometry and materials); use of specialized hardware (many-core processors and GPU). Practical examples and important results are illustrated in radiotherapy, nuclear medicine and radiology.
- Introduction to Machine Learning:
- Context and purpose of Artificial Intelligence, Machine Learning, and Deep Learning.
- The various types of learning problems (supervised, non-supervised, reinforcement, transfer).
- The various types of data sets and their purpose (training, validation, test).
- Short introduction to optimization.
- A few techniques:
- Principal component analysis, linear discriminant analysis.
- Decision trees and random forests.
- Support Vector Machines.
- Neural networks, from single artificial neuron to deep (convolutional) networks.oInterpretation of the results (ROC curve/sensitivity/specificity/...).
- Specifics of data collection for AI/ML/DL in medical physics (access to patient data and the importance of consistent patient data; how to guide efforts in structured reporting).
- Big data and data preprocessing (images, radiomics,.. ).
