Does ultrasound have good resolution?

The spatial resolution of ultrasound is actually quite good. The limitation is that the field-of-view is usually smaller than other imaging techniques. Ultrasound is also constrained by not being able to image through bone or gasses. Axial resolution depends on frequency, pulse duration, sampling frequency.

What is the resolution of an ultrasound image?

Axial (also called longitudinal) resolution is the minimum distance that can be differentiated between two reflectors located parallel to the direction of ultrasound beam. Mathematically, it is equal to half the spatial pulse length. Axial resolution is high when the spatial pulse length is short.

What does funk QA Phantom measure?

Each phantom consists of a set of nesting 15 cm thick solid PMMA disks measuring 16 cm (head) and 32 cm (body) in diameter. The adult head disk is also suitable for pediatric body measurements. The CI1-007A includes a third nesting disk measuring 10 cm in diameter for pediatric head measurements.

What is the ultrasound resolution Phantom QA tool?

The Ultrasound Resolution Phantom is an ultrasound QA tool for simultaneous assessment of axial, lateral and elevational resolution. The phantom is constructed from the patented solid elastic material, Zerdine ® and is housed in a rugged ABS casing. Zerdine accurately simulates the ultrasound characterisitcs of human liver tissue.

What do you need to know about ultrasound Phantoms?

The General Purpose Ultrasound Phantom phantoms comes standard with a robust housing, rugged carry case, 4-year warranty, and user guide. Performance Measurements: Dead Zone. Horizontal Distance Accuracy. Vertical Distance Accuracy. Depth of Penetration. Image Uniformity. Axial Resolution.

What does ultraiq phantom image analysis software do?

UltraiQ Software brings automated phantom image analysis to diagnostic ultrasound. Ultrasound quality assurance ensures system performance over time and catches degradation in image quality before it affects the diagnostic value of the clinical ultrasound exam. Yet, establishing a QA program can be time consuming and cumbersome.

How is the accuracy of a phantom determined?

By scanning a phantom using known targets, the accuracy of caliper measurements can be determined. Because vertical distance measurements are based on the timing of the ultrasound image, vertical distance errors are less likely to occur than horizontal measurements. 3. Axial and Lateral Resolution
