Image optimization

This page will highlight key points in acquisition and optimization of ultrasound images.

Linear array probe

The linear array probe is high-frequency, which offers superb near-field resolution. High frequency wavelengths undergo much attenuation and therefore offer little in the way of depth. Nonetheless, its design is ideal for pleura visualization, vascular access, optical nerve sheath and looking for venous thrombi in deep vasculature.

Phased array probe

The phased array probe is a low-mid frequency probe. The sequential activation of the crystals allows for clear dynamical visual imaging of cardiac structures. But the phased array is much more than the “cardiac probe”, as it can used for the chest, abdomen, and transcranial Doppler.

Curvilinear probe

The curvilinear probe is a low-frequency probe with high depth of penetration. Low frequency sound waves undergo less attenuation, but also offer less resolution. While many think the curvilinear probe is simply the “abdominal probe”, it actually offers much more. You can use it for lung/thoracic ultrasound to look for sliding/ pleural effusions. On top of being excellent for abdominal imaging, it can also be used for vascular access in the severely overweight individual.

Machine interface

Make sure you are comfortable with your machine to access all the settings including:
1. Depth
2. Gain
3. Beam orientation
4. Sector width
5. Dynamic range
