WE‐A‐103‐01: Ultrasound

Abstract

Ultrasound quality control (QC) testing is often over‐looked in ultrasound imaging practice because there are few regulations requiring regular QC of these systems. Many sites rely on the manufacturer's preventive maintenance program to ensure these systems are functioning optimally. However, the regulatory climate is changing, placing emphasis on safe and effective imaging practice. Regular QC testing of ultrasound equipment is a valuable tool that helps ensure proper function and good image quality in ultrasound imaging. This two‐hour session is organized in two parts. The first hour will cover the basic concepts of ultrasound performance measurement, including the tests that are recommended for acceptance and annual testing as well as routine QC, the rationale for these tests, and specific testing methods. It will also include what the physicist needs to know about ultrasound accreditation. The next hour includes two presentations related to quantitative assessment of ultrasound QC. First presented is the work of the AAPM working group on Quantitative B‐mode Ultrasound QC Test Development. This group has designed software intended to aid in the evaluation of transducer element condition. The second presentation will demonstrate use of a user‐friendly automation software, developed at the University of Wisconsin, for periodic rapid quality assurance (QA or QC) using the tissue‐mimicking conical window phantom described last year. The phantom has been designed specifically for determination of three basic parameters. A method for organizing an electronic filing system for paperless recording of results will also be described.Learning Objectives:1. Understand what constitutes an effective ultrasound QC program.2. Achieve familiarity with common ultrasound QC test methods and phantoms.3. Understand what the physicist needs to know about ultrasound program accreditation.4. Learn about a public software tool being developed by the AAPM Ultrasound Subcommittee to detect and assess transducer uniformity artifacts.5. Learn about a user‐friendly automation software tool to address the most‐recommended ultrasound QC tests.
