Vector blood velocity estimation in medical ultrasound

11/12/2013 · Background. Recommended phantom-based quality assurance measurements in B-mode ultrasound (US) may be tedious. For the purpose of cost-effective US quality assurance it is important to evaluate measurements that effectively reflect the quality of US scanner.

Axial Length Measurement with the Zeiss IOLMaster

The latter requires dexterity to position the probe at an appropriate distance from the cornea while remaining perpendicular to the retina and directing sound waves through the center of the cornea and lens. The fixed immersion technique, with a short learning curve, minimizes significant variables such as corneal compression, alignment of the ultrasound beam, and probe insertion. This leads

Vector blood velocity estimation in medical ultrasound

Ultrasound axial length measurements have been the gold standard for many years. With the introduction of optical biometry , technology has become more advanced. Partial coherence interferometry based biometry presents an alternative for precise ocular measurements, used not only for axial length, but anterior chamber depth, pachymetry and lens and retinal thickness measurements.

Interpretating Axial Length Measurements ALM

Axial length is defined as the distance from the anterior corneal surface to the retinal pigment epithelium. Can be performed using optical or ultrasound methods, which can further be done by direct contact or immersion. A combination of these measurements prevents errors in AL measurements. Optical methods like IOL master have benefits of non-contact procedures along with greater accuracy
