Criteria for
Core Courses:
Describe how the course meets the specific bullet points for the proposed core requirement. Give concrete and detailed examples for the course syllabus, detailed outline, laboratory material, student projects, or other instructional materials or method.

Core courses must meet the following requirements:

  • They explicitly help students understand what liberal education is, how the content and the substance of this course enhance a liberal education, and what this means for them as students and as citizens.
  • They employ teaching and learning strategies that engage students with doing the work of the field, not just reading about it.
  • They include small group experiences (such as discussion sections or labs) and use writing as appropriate to the discipline to help students learn and reflect on their learning.
  • They do not (except in rare and clearly justified cases) have prerequisites beyond the University's entrance requirements.
  • They are offered on a regular schedule.
  • They are taught by regular faculty or under exceptional circumstances by instructors on continuing appointments. Departments proposing instructors other than regular faculty must provide documentation of how such instructors will be trained and supervised to ensure consistency and continuity in courses.

Criteria for
Theme Courses:
Describe how the course meets the specific bullet points for the proposed theme requirement. Give concrete and detailed examples for the course syllabus, detailed outline, laboratory material, student projects, or other instructional materials or methods.

Theme courses have the common goal of cultivating in students a number of habits of mind:
  • thinking ethically about important challenges facing our society and world;
  • reflecting on the shared sense of responsibility required to build and maintain community;
  • connecting knowledge and practice;
  • fostering a stronger sense of our roles as historical agents.

Course Syllabus
Course Syllabus: For new courses and courses in which changes in content and/or description and/or credits are proposed, please provide a syllabus that includes the following information: course goals and description; format;structure of the course (proposed number of instructor contact hours per week, student workload effort per week, etc.); topics to be covered; scope and nature of assigned readings (text, authors, frequency, amount per week); required course assignments; nature of any student projects; and how students will be evaluated. The University "Syllabi Policy" can be found here

The University policy on credits is found under Section 4A of "Standards for Semester Conversion" found here. Course syllabus information will be retained in this system until new syllabus information is entered with the next major course modification. This course syllabus information may not correspond to the course as offered in a particular semester.

(Please limit text to about 12 pages. Text copied and pasted from other sources will not retain formatting and special characters might not copy properly.)

BMEn 5111: Biomedical Ultrasound
3.0 credits
Prof. Shai Ashkenazi ( )
This course is aimed to provide a gateway into the rich and versatile field of biomedical ultrasound. We will start from the basic physics of ultrasonic waves and their interaction with biological tissues, and then move to describe ultrasonic devices, imaging technology, and their applications in medicine and biology. New and emerging techniques in biomedical ultrasound will be introduced in the last part of the course.
The major sections of the course include
┐        Physics of ultrasound - Propagation in fluids and solids, reflection, scattering, absorption, ultrasonic properties of tissues.
┐        Transducer technology - Piezoelectric transducers, CMUTs
┐        Medical ultrasound imaging - Pulse echo, flow estimation and Doppler imaging, design of imaging transducer arrays, contrast agents.
┐        Photoacoustic imaging ┐ Laser generated ultrasound, Acoustic field of volume sources, photoacoustic image reconstruction, tissue optical properties, diffusion model for tissue optics, photoacoustic contrast agents.
┐        Applications of non-linear acoustic: Basic concepts of non-linear waves, harmonic imaging, and radiation force imaging.

Prerequisites:        IT upper division undergraduate or graduate student, or consent of instructor
Physics II (PHYS 1112 or equivalent), Calculus II (Math 1272 or equivalent).
Course Format:  Lectures
Course Requirements:        Homework sets, midterm exam and a final project
Grading: Midterm 30%, Homework 30%, Final Project 40%
Office hours:         Monday 2-4pm,. Shepherd Lab 391 (or by appointment)
