The preparation and application of anatomic models and phantoms to facilitate learning diagnostic ultrasound is described. Imaging with diagnostic ultrasound requires mastery of many skills, along with knowledge of sound‐tissue interactions which contribute to the formation of diagnostic images and artifacts. Understanding the genesis of artifacts encountered during ultrasound scanning can avoid misinterpretation and aid diagnosis. In addition, development of machine related knowledge and skills, including manipulation of the transducer and the selection of correct settings for variables such as gain, power, time‐gain compensation, and transducer type, is dependent on an understanding of how these factors affect the image. The normal appearance of an organ relates to both its echogenicity and morphologic characteristics, and confirmation of the nature of an abnormality often requires ultrasound guided biopsy. The use of anatomic models and phantoms in ultrasound instruction allows principles to be demonstrated, knowledge acquired, and biopsy procedures practiced and mastered in a controlled setting. This can minimize live animal use, and enhance the knowledge base and skills of the clinician prior to applying this diagnostic technique to the clinical patient.
