ECE 445 Safety Guidelines

  1. No one is allowed to work in the lab alone. At least 2 people must be in the lab at all times.
  2. Everyone must complete a mandatory online safety training in order to be allowed to work in the lab. Certificates of completion must submitted on Compass2g.
  3. Any group planning on working with high voltages is required to complete additional safety training.
  4. Any group charging or utilizing certain battery chemistries must read, understand, and follow guidelines for safe battery usage.
  5. If you're working on any project involving electric current running through a human subject, you must read through and understand these guidelines for Safe Current Limits!

Requirements and Grading

The Laboratory Safety Training must be completed by all students enrolled in ECE 445. This module can be found on University's Division of Research Safety website.

Submission and Deadlines

Certificates of completion must submitted on Compass2g the due date listed on the Course Calendar. Students who have not completed this requirement will have lab access revoked.

Filtered Back – Projection Optical Demonstration

Featured Project

Project Description

Computed Tomography, often referred to as CT or CAT scans, is a modern technology used for medical imaging. While many people know of this technology, not many people understand how it works. The concepts behind CT scans are theoretical and often hard to visualize. Professor Carney has indicated that a small-scale device for demonstrational purposes will help students gain a more concrete understanding of the technical components behind this device. Using light rather than x-rays, we will design and build a simplified CT device for use as an educational tool.

Design Methodology

We will build a device with three components: a light source, a screen, and a stand to hold the object. After placing an object on the stand and starting the scan, the device will record three projections by rotating either the camera and screen or object. Using the three projections in tandem with an algorithm developed with a graduate student, our device will create a 3D reconstruction of the object.

Hardware

• Motors to rotate camera and screen or object

• Grid of photo sensors built into screen

• Light source

• Power source for each of these components

• Control system for timing between movement, light on, and sensor readings
