The term transverse refers to orientation 90° to the long axis of the structure being evaluated or the short axis of the patient (see Figures 4.1, 4.2, 4.3). The probe marker is turned to the left (or counterclockwise) to the patient’s right side. Thus, in transverse planes, the probe marker is directed to the patient's right side to maintain the same orientation as radiography, right side on left side of ultrasound (and radiographic) image.

With that said, let’s get on with Dr Fulton’s chapters that will cover in more detail the physics of ultrasound, its artifacts, and various pointers on the ultrasound machine features and settings and image acquisition.

It's worth your effort and time investment to learn this core skill – POCUS and FAST improve care and save lives!

Figure 1.6. Longitudinal (sagittal) planes and orientation. Make the screen marker and the probe marker both consistent with “head to the left and tail to the right,” which is the same orientation as radiography. (A) shows the head of the dog and (C) its tail. In (B), the probe is placed on the truncal area of the same dog. The white circle highlights the probe marker (can be a notch, a raised line or button, or an LED light). Every probe has its marker. In (D) is a pictorial of the ultrasound screen, and the green dot indicates the screen marker (arrow ←). Make sure that this is to the left of the screen and the probe marker is toward the head of your patient. In (E) is a radiograph showing the same orientation used for ultrasound, “head to the left, tail to the right.” Courtesy of Dr Gregory Lisciandro, Hill Country Veterinary Specialists and FASTVet.com, Spicewood, TX.
