Biomedical Engineering Summer School

Artificial Intelligence

Prof. Dr. Yvo Marcelo Chiaradia Masselli

The Introduction to Artificial Intelligence (AI) course aims to present an overview of the field of AI, the main techniques and algorithms involved in real applications.

The course combines theoretical sessions, computer simulations and covers the following topics:

• Fundamentals of Artificial Intelligence.
• Knowledge representation.
• Informed and uninformed search methods.
• Fuzzy logic and fuzzy controllers.

In the end, the student should be able to understand and develop a solution based on the learned algorithms. These will serve as the basis for subsequent lectures on the AI ​​course track.

Biomedical Image Processing

This is an introductory course in the fundamentals of biological and medical imaging and image processing, including pre-processing and enhancement techniques, filtering, object detection, and image segmentation.

Participants will learn the basics of digital imaging and will gain experience in Python’s image processing abilities. We are also going to meet CellProfiler, an open-source application for batch processing, measuring, and analyzing images. We will see how to use them via real-life examples of various biological experiments covering the following topics.

Course topics:

• Fundamentals of image acquisition and image processing
• Intensity-based methods: histogram correction and thresholding

• Image segmentation and object identification
• Working with multi-channel images, measuring colocalization

Biomedical Applications of Machine Learning

Dr. Gábor Kertész

The goal of the lectures is to provide an introduction to image recognition with neural networks, both is theory and in practice.

The course starts with a basic introduction to the fundamentals of image recognition using neural networks. On the practical side, Tensorflow and Keras is introduced as the most common frameworks used by machine learning engineers.

During the course the students will get an understanding on how Neural Networks are trained, evaluated, and what common problems could occur. After introducing Convolutional Neural Networks, classical architectures are analysed along with modern, state-of-the-art solutions and techniques, which improve the performance of neural networks.

Course topics:

• Regression and classification in fully connected networks
• Handling image data
• Convolutional Neural Networks
• Classic architectures and techniques
• State-of-the-art solutions and approaches to increase performance
• Hands-on with Tensorflow and Keras

Introduction to Project Management

Dr. Miklós Daróczi, Associate Professor

The main objective of the course is to deliver some theoretical and practical knowledge related mainly to the project planning, scheduling and budgeting. The module starts by defining the project and differentiating project management from general management. The project manager’s role, the project life cycle and the elements of project plan are also briefly discussed. The common formats of schedule the Gantt-charts and PERT/CPM networks, some methods of budgeting and cost estimating are also covered. Based on these techniques students will be able to participate in project planning and implementation.

Student teams will prepare a report and give a presentation on a special project. The purpose of this assignment is to deepen your knowledge on planning projects and to share that knowledge with the rest of the group. The topic of the project will be selected by the students.

3D Modelling and Simulation of Biomechanical Structures

Alin TOTOREAN, Eng, PhD, Sergiu GALATANU, Eng, PhD

The concept of personalized medicine has strongly evolved nowadays and is more and more used in clinical practice. For example, in orthopedics or cardiovascular medicine having patient specific models before interventions proves to be useful for physicians, since it allows them to plan the procedure in advance taking into consideration patient’s details. The process requires 3D models of the anatomical structures and further prototyping or performing computational simulations.

Brain-Computer-Interfaces

Prof. Dr. Olena Kuzmicheva

Development of assistive robotic devices for persons with motor disabilities is a challenging task. Besides development of autonomous task execution by robotic devices, the problem of robot system control by the user arises, when usual interaction modalities like mouse or joystick cannot be used due to physical restrictions of the person. New modalities become necessary to command the robotic system hands-free. The course introduces different aspects of hands-free control with focus on Brain Computer Interfaces (BCI) as one of possible input modalities. The participants will learn basics of non-invasive BCIs including different aspects of signal processing and directly apply the achieved knowledge in the practice. Therefore, the course combines theoretical sessions with programming units and experiments in the lab and reflects following topics:

• Introduction to hands-free control and different input modalities
• Electroencephalography (EEG), EEG based BCIs as input modality, useful features and BCI paradigms
• Selected topics of signal processing for EEG based BCIs
• Application of BCI to (robotic) system control
• Design and implementation of a small scale BCI controlled application.

The course addresses undergraduate students in engineering and computer science. Medical background is not required.

Amperometric Biosensors and Related Electronics

Dr. Cengiz Koçum, Prof. Dr. Dilek Çökeliler Serdaroğlu

Biosensors are used to detect biological or chemical markers (bio-chemicals, DNA, protein, cells etc.) in order for diagnosis, environmental monitoring and pharmaceutical research. This course represents the fundamental science and engineering concepts of designing biosensors through a common example. Biosensors have three main parts; biorecognition layer, transducers and electronics and they usually produce an electrical signal related to the specific analyte. In this course with lectures and practical exercises students will design and implement the main parts of an amperometric biosensor capable of glucose monitoring. Students will gain an insight of the complexities and design principles of a biosensor from scratch.

Course Outline:

• Introduction to biosensors and nanobiosensors
• Types of biorecognition elements
• Surface functionalizing and modification approaches for biosensors
• Transducer Basics: Sensors and Actuators
• Signal acquisition and conditioning principles
• Amperometric glucose biosensors
• Design and production of glucose sensing layer
• Signal conditioning for the amperometric glucose biosensor
• Electronic circuit and PCB design.

Instrumentation, Acquisition and Signal Processing for Biosignals

Dr. Mehmet Yüksekkaya

Biomedical signals are used to obtain crucial information about human health for diagnosis and treatment follow up. Acquiring biosignals from human body to a computer system is called biosignal acquisition and conditioning. For signal acquisition and conditioning, appropriate electronic instrumentation should be designed. In order to extract the crucial information from the acquired data, it should be processed.

This course is designed to be a practical introduction for all those stages. Students will design a basic instrumentation circuitry to acquire a specific biosignal and learn the fundamentals of signal conditioning. Further, they will learn the essential principles of digital signal processing and will apply those principles in a practical example. After this course, students will get significant theoretical and practical skills for biosignal acquisition and processing.
