Otolaryngologic Clinics of North America, 2010
This content is designed to acquaint the clinician with some of the more common ultrasonographic manifestations of clinical conditions that the otolaryngologist is likely to encounter in a general practice. The clinician requires a thorough knowledge of head and neck anatomy to best interpret the variations from normal structures demonstrated on ...

BMUS Bulletin, 1996
Ultrasound is an extremely useful and versatile method of assessing soft tissue abnormality in rheumatological conditions. It is best performed as an extension of clinical examination. Ultrasound has the advantage of not only being able to demonstrate abnormalities but also allows transducer compression of those abnormalities to see if it reproduces ...

Radiologic Clinics of North America, 2000
Sonography, when performed by an experienced examiner, can be used for evaluation of many pathologies in the head and neck area. Some benign neck lesions, such as cysts, lipomas, carotid body tumors, and hyperplastic lymph nodes, have typical sonomorphology.

Journal of Biomedical Engineering, 1988
Modern ultrasonic transducers mainly employ lead zirconate titanate (PZT) but vinylidene fluoride trifluoroethylene copolymer (P (VDF-TrPE)) is becoming more competitive. The static scanner is now largely replaced by mechanical or electronically controlled array real time systems; the speed of scanning is limited by the speed of sound and the ...

Surgeon-performed ultrasound: endorectal ultrasound
Surgical Clinics of North America, 2004Endorectal (ERUS) and endoanal (EAUS) ultrasound imaging is increasingly being performed by surgeons in the office and outpatient setting for the assessment of both benign and malignant disease. Multiple studies have demonstrated the accuracy of these modalities in identifying pertinent anatomy and anatomic abnormalities.

The Journal of the Acoustical Society of America, 1955
The ultrasonic focused beam method of producing selective, precisely localized, quantitatively reproducible lesions in the brains of experimental animals is illustrated. The acoustic calibration procedure, the surgical preparation of the animal, and the technique of irradiation are demonstrated in this motion picture. The complete instrumentation setup

This article reviews the use of point-of-care ultrasound (POCUS) for evaluating the aorta from anatomy and image acquisition to the diagnosis of aortic pathology, including aneurysms and dissection. Ruptured aortic aneurysm and aortic dissection are associated with high mortality and often experience a delay in time to diagnosis.

Muscle ultrasound is an ideal imaging modality that allows for noninvasive, radiation-free point-of-care neuromuscular imaging. There are many potential applications of muscle ultrasound, including identification of abnormal muscle movements such as fasciculations, evaluation of muscle trauma, identification of physiologic parameters such as pennation ...

Endobronchial Ultrasound: The Basics of Ultrasound
2017Medical ultrasound imaging consists of using high-pitched sound bouncing off tissues to generate images of internal body structures. The ultrasound waves are created from mechanical or electronical oscillations of crystals in a so-called transducer, which are excited by electrical pulses (piezoelectric effect).

Acta Obstetricia et Gynecologica Scandinavica, 1970
Abstract. The placental location and the boundaries of the placenta were established by two‐dimensional ultrasound examination in 107 cases. In 45 of them, the result of the ultrasound placentography was correlated with the finding at Caesarean section.
