which is the case only if the reference planes do not change position during the time interval or if the difference between the two planes is negligibly small. It may be that for some diseases, such as diabetic retinopathy and other retinal vascular diseases, that only the inner retinal layer moves and the reference planes (e.g., the tips of the outer segment or the first bright RPE reflection)...

The purposes of this study were to examine the effect of sensitivity encoding (SENSE) factors on cortical thickness measurements and to determine which SENSE factor to use to reliably measure cortical thickness in 3.0 T and 1.5 T T1-weighted MRI images. The 3D T1-TFE images were acquired from 11 healthy volunteers with 6 different SENSE acceleration factors from 1.0 (without SENSE acceleration)...

Ultrasonic guided wave inspection is much more efficient than traditional point-bypoint examination. Guided waves can propagate over long distances from a single position, and therefore is a good method of evaluating thickness degradation, especially for large-area structures such as pipes and vessels. In this paper, guided wave thickness measurement potential is studied utilizing a peak freque...

Epicardial adipose tissue (EAT) is ectopic visceral fat surrounding the heart that is located close to the coronary arteries. Excessive EAT has been reported to be associated with known cardiovascular risk factors 1, 2). Moreover, several investigators have shown that quantity of EAT can be a marker for the presence and severity of coronary artery disease (CAD) 3-6). Computed tomography and Mag...

background and aims. palatal masticatory mucosa serves as donor material in periodontal plastic surgery. this study determined the palatal mucosal thickness in indian subjects aged 14−59 years by direct bone sounding and its association with gender and age. materials and methods. this observational study was conducted on 40 dentate systemically and periodontally healthy indians (age range of 14...

In this work we present the concept of wide band interferometry as opposed to white-light interferometry to introduce a thickness measurement method that gains precision when the bandwidth is reduced to an adequate compromise in order to avoid the distortions arising from the material dispersion. The use of the widest possible band is a well established dogma when the highest resolution is desi...

OBJECTIVE To assess the intrarater and interrater reliability of the supraspinatus thickness measured by ultrasonography (US) in normal subjects and to identify the relationship between the supraspinatus thickness measured by US and cross sectional area (CSA) of the supraspinatus muscle by magnetic resonance imaging (MRI) in hemiplegic patients. METHOD We examined 20 shoulders of normal subje...
