98 Credit Course DescriptionsTacoma Community CollegeDiagnostic Medical SonographyDiagnostic Medical SonographyDMS 100Introduction to DiagnosticMedical Sonography (4)Introduces the field of sonographyincluding: the history and uses of ultrasound,roles and responsibilities of a diagnosticmedical sonographer, health care settingsthat use ultrasound, as well as job andtraining opportunities for sonographers.Discusses medical ethics and legal issuesrelevant to sonography.Prerequisites: Acceptance into the program orprogram chair permission.DMS 105Ultrasound Cross-Sectional Anatomy (4)Provides information on cross-sectionalanatomy in the human body with anemphasis on the organs of sonographicinterest. Different scanning planes arerepresented including longitudinal,transverse, coronal and oblique views.Students also gain an understanding oftransducer positioning in relation to organswithin the body, and correlate their studieswith sonographic images.Prerequisites: Acceptance into the program orprogram chair permission.DMS 110Pathophysiology I (3)Explores the pathogenesis of diseaseprocesses and their impact on the humanbody. Discusses the clinical manifestations,diagnosis, treatment and surgicalinterventions of different disease processesaffecting specific body systems. Emphasizesdisease processes relevant to sonography.Prerequisites: Acceptance into the program orprogram chair permission.DMS 111Pathophysiology II (3)A continuation of Pathophysiology I.Discusses clinical manifestations, diagnosis,treatment and surgical interventions ofdiseases affecting specific body systems.Emphasizes disease processes relevant tosonography.Prerequisites: Successful completion of DMS 110.DMS 120Abdominal Scanning and Techniques (5)Introduces ultrasound terminology and basicscanning techniques. Discusses the normaland pathologic appearances, laboratory testsand clinical signs and symptoms pertinent tothe organs studied. Routine scanningprotocols are learned and practiced duringlecture/lab.Prerequisites: Acceptance into the program orprogram chair permission.DMS 121Small Parts and IntraoperativeScanning and Techniques (5)Focuses on the sonographic scanningtechniques of various superficial structures.Reviews the anatomy, physiology, andpathology of these small parts; discussinglaboratory tests and clinical signs andsymptoms. Also explores the use ofultrasound in surgical procedures. Routinescanning protocols are learned and practicedduring lecture/lab.Prerequisites: Acceptance into the program orprogram chair permission.DMS 122Gynecological and ObstetricalScanning and Techniques (5)Provides information on the femalereproductive system and fetal developmentin the first trimester, including: a review offemale pelvis anatomy, physiology andassociated pathologic findings. Introducesembryonic development and maternalchanges in the first trimester. Focuses onscanning protocols and techniques, which arediscussed and practiced in lecture/lab.Prerequisites: Successful completion of DMS 120and 121.DMS 123Obstetrical Scanning and Techniques (5)Provides information on the femalereproductive system and fetal development.Emphasizes obstetrical states in the secondand third trimesters and the associatedpathological findings. Basic scanningtechniques and protocols are introduced andpracticed in lecture/lab.Prerequisites: Successful completion of DMS 122.DMS 130Ultrasound Physics and Instrumentation I (3)Provides a theoretical and practical understandingof acoustic physics and its applicationin diagnostic medical sonography. Includesa review of related mathematical conceptsand explores wave concepts, propertiesof attenuation, ultrasound beam formation,transducer construction, and function andsystem operation.Prerequisites: Acceptance into the program orprogram chair permission.DMS 131Ultrasound Physics and Instrumentation II (3)A continuation of Ultrasound Physics andInstrumentation I. Topics covered includehemodynamics, Doppler physics (includingcolor and spectral Doppler), acousticartifacts, bioeffects and safety and qualityassurance.Prerequisites: Successful completion of DMS 130.DMS 150Ultrasound Clinical I (2)Provides students the opportunity to applysonographic theory to observation andlimited hands-on scanning in a clinicalsetting. Includes professional skills, scanningtechniques, protocols, patient care andquality assurance.Prerequisites: Acceptance into the program orprogram chair permission.DMS 151Ultrasound Clinical II (5)A continuation of Ultrasound Clinical I. Thestudent will observe, assist, and performvarious technical, clerical, professional,patient care, and sonographic duties understrict supervision. Requires completion ofclinical competencies which will be observedand signed-off by a supervising sonographer.Prerequisites: Successful completion of DMS 150didactic and lab coursework with a passing grade of‘C’ or higher.DMS 152Ultrasound Clinical III (8)A continuation of Ultrasound Clinical II.Continued observation with increasingperformance of all duties of a sonographer ina clinical setting. Patient examinations areperformed under generalized supervision.Requires completion of clinical competenciesPrerequisites: Successful completion of DMS 151didactic and lab coursework with a passing grade of‘C’ or higher.
