Abstract Ultrasound imaging, one of the most widely used diagnostic modalities, anchors fields medicine, physics, and engineering. In university classrooms, however, ultrasound imaging is often taught passively with a lack practical element as clinical machines are not easily available there very few alternative teaching tools on market. As part an undergraduate student project, we have develop...

OBJECTIVE To compare the accuracy of central corneal thickness measurements using ultrasound biomicroscopy, Orbscan II tomography and an Artemis-2 very high frequency ultrasound scanner. METHODS The prospective study was conducted at Eye World Centre, Riyadh, Saudi Arabia, from September to November 2012. One eye from each of 60 normal subjects was analysed. The central corneal thickness was ...

Medical Physics at CancerCare Manitoba has developed its own ultrasound phantom. The following table is intended as a quick reference guide when performing the quality assurance measurements. Instructions Limits Record Items Required ultrasound contrast-detail phantom degassed water or coupling gel paper towels for clean up (optional) lab stand and clamp to hold probe Physical check: 1. probe s...

The purpose of this in vitro study was to assess the trueness a dental implant scanned using an intraoral high-frequency ultrasound prototype and compared with conventional optical scanners. An acrylic resin cast containing at position 11 fringe projection 3D sensor for use as reference dataset. same 10 times each group. Ultrasound scanning performed probe (42 MHz, aperture diameter 4 mm focus ...

A hybridized dual-imaging system combining real-time ultrasound imaging and MRI was utilized for cardiac imaging at 1.5 T and 3 T. The ultrasound scanner with a programmable software interface was connected via computer to the MRI scanner. Electronic noise was eliminated with electromagnetic shielding and grounding to the screen room. At 3 T, real-time prospective motion compensation in dynamic...

MOTIVATION Commercial ultrasound machines in the past did not provide the ultrasound researchers access to raw ultrasound data. Lack of this ability has impeded evaluation and clinical testing of novel ultrasound algorithms and applications. OBJECTIVES Recently, we developed a flexible ultrasound back-end where all the processing for the conventional ultrasound modes, such as B, M, color flow...
