Studying ultrasound physics is one practical way to improve scanning technique and patient care. Both equipment operation and image interpretation are highly operator-dependent. An understanding of the basic physical principles of sound and its interaction with the tissue is a critical component in ultrasound imaging. In addition to reviewing these...
By the end of this program, the viewer should be able to: Recognize how an ultrasound image is generated. Review the concept of spatial resolution and recognize the influencing factors. Describe contrast resolution and recognize the influencing factors. Report the importance of great elevational resolution and how to achieve it.
Course objectives for this program specifically target diagnostic medical sonographers, echocardiographers, and vascular technologists. All other professionals practicing in this field may also benefit. NOTE: Regardless of your imaging specialty, you may apply for continuing education credit. Refer to the Continuing Education Credit page for additi...

Diagnostic ultrasound is a pulse-echo technique. Pulses of sound are sent into the body by a transducer. This same transducer listens for the returning echoes produced by the soft tissues of the body and the system processes the echoes for display. Obtaining an image involves: The propagation of speed of sound in soft tissue Transducer arrays Beamf...
Sector probes or transducers are also called phased arrays. Figure 3 Types of Probes These transducers have the smallest footprint. Footprint refers to the surface area of the probe in contact with the patient. The sector probes usually contain the fewest number of elements and all the elements are utilized as a group, with small time differences,...
Convex probes are operated exactly like linear probes. The beam is not steered, but you get a pie-shaped view by changing the geometry of the transducer itself.
Spatial resolution is also called detail resolution. It includes axial and lateral resolution.
Axial resolution is the dimension of the image parallel to the direction of sound travel or represented when we describe two structures, one in front of the other, on the display. Axial resolution is associated with the length of the beam or the X axis. It runs from the face of the transducer deep into the body. Axial resolution depends on the wave...
Lateral resolution is the dimension of the image perpendicular to the direction of sound travel or represented when we describe two structures, side by side, on the display. Lateral resolution is associated with the width of the beam or the Y axis and the long axis of the transducer. Focusing, frequency, aperture, the number of elements, and the nu...
Contrast resolution is the ability to discern many colors or shades of gray. Contrast resolution describes the shades of gray that are represented on the image. Dynamic range affects the contrast resolution. Increasing the dynamic range provides more shades of gray and allows us to display subtle differences on the screen. We see the shades of blac...
Elevational resolution is the slice thickness of your ultrasound scan. Historically, the elevation plane has been set by the manufacturer with an acoustic lens. With the new matrix array technology, the operator is able to control the focus within the elevation plane. Elevational resolution is known by many other names. It can be called the short a...
Single row of elements Lens on the face of the transducer for single fixed elevational focus Less focus in the far field & near field mean less image quality
