Versatile, Reusable, and Inexpensive Ultrasound Phantom Procedural Trainers.
We have constructed simple and inexpensive models for ultrasound-guided procedural training using synthetic ballistic gelatin. These models are durable, leak resistant, and able to be shaped to fit a variety of simulation scenarios to teach procedures. They provide realistic tactile and sonographic training for our learners in a safe, idealized setting.
متن کاملPreparation of a homemade ultrasound biopsy phantom.
Sonographic guidance has long been employed for biopsy with sector scanners by utilizing attachable offset guides,’-5 by dedicated linear array system^,^,^ or by “free hand.”’ All of these techniques are bimanual, in contrast to a diagnostic scan or biopsy alone. The dedicated systems provide a slot that causes the needle to be directed into the center of the scanning plane. When the procedure ...
متن کاملEvaluation of a Cardiac Ultrasound Segmentation Algorithm Using a Phantom
This paper evaluates the performance of a level set algorithm for segmenting the endocardium in short-axis ultrasound images. The evaluation is carried out using an anthropomorphic ultrasound phantom. Details of the phantom design, including comparison of the ultrasound parameters with in-vitro measurements, are included. In addition to measuring segmentation accuracy, the effectiveness of the ...
متن کاملLocalizing target structures in ultrasound video - A phantom study
The problem of localizing specific anatomic structures using ultrasound (US) video is considered. This involves automatically determining when an US probe is acquiring images of a previously defined object of interest, during the course of an US examination. Localization using US is motivated by the increased availability of portable, low-cost US probes, which inspire applications where inexper...
متن کاملA low-cost ultrasound phantom of the lumbosacral spine.
BACKGROUND AND OBJECTIVES This report describes the production of a low-cost ultrasound phantom of the lumbosacral spine. The phantom should be a very useful tool to teach the basic skills for ultrasound-guided procedures of the lumbosacral spine. METHODS A lumbosacral spine model is secured to the bottom of a microwave-safe container and is immersed in a concentrated gelatin solution. After ...
