Thursday Parallel 5 Live Q&A

Thursday, 13 August 2020, 15:50 - 16:35 UTC

Moderators: Irena Zivkovic

Skill Level: Basic

Session Number: S-Tu-08

Overview
This course will provide resources for creating low-custom custom electronics, such as PCB design, circuit simulation, and prototyping methods.

The complete MR scanner is a complex system involving electronic design, electromagnetic interactions, pulse sequence design, and image reconstruction. This 4-day course builds on the weekend sessions to provide starting information so that students can leverage publicly available tools to embark on simple prototypes in the hardware, electromagnetics, sequence design, and reconstruction. The first day will overview electronic prototyping tools.

Target Audience
Students, clinicians, engineers, and physicists who are interested in getting started with simple electronic controls, systems, and hardware/software prototyping.

Educational Objectives
As a result of attending this course, participants should be able to:
- Identify resources for PCB fabrication, easy-to-learn microcontrollers, and programming;
- Describe appropriate tools for manufacturing electronics;
- Construct basic electronic components in their own lab; and
- Explain operation of a gradient or shim controller.

		Do-It-Yourself Electronics for MRI Natalia Gudino Watch the Video
		The Design & Implementation of Digital Receivers for MRI Robin Dykstra Watch the Video Some of the steps and tools that people can use to design and build their own digital receivers are described. The key topics covered will be the digital signal processing chain, graphical FPGA circuit design using custom and free IP and the key signal processing IP blocks such as the CIC low pass decimating filter. The topic of high-performance sampling is also addressed where simultaneous subsampling and oversampling is performed to achieve high dynamic range at input frequencies of several hundred MHz. Different hardware implementations are then presented ranging from prebuilt but closed solutions to custom “roll your own” approaches.
