OBJECTIVES To compare the interobserver reliability of antral follicle counts made using real-time two-dimensional (2D) ultrasound with offline counts made from stored three-dimensional (3D) data and to assess the time required for such counts. METHODS Two observers conducted transvaginal ultrasound examinations in 45 subfertile women in the early follicular phase of the menstrual cycle. Antr...

Results of this study indicate that correlations between real-time ultrasound loin depth and carcass loin muscle area and between carcass loin depth and carcass loin muscle area are high. However, using carcass loin muscle area as the true value, the standard error of prediction for real-time ultrasound loin muscle area was lower than those for loin muscle areas predicted from either real-time ...

Background: The accurate differentiation of perinatal torsioned ovarian cysts (PTOCs) in neonates is of utmost importance. This importance is due to the fact that if PTOCs are diagnosed properly, minimally invasive or conservative management approaches can be offered. The present study aimed to describe the ultrasound findings of PTOCs and compare the results with pathological findings.Me...

Microfiltration can clarify pomegranate juice; however, fouling is a limiting phenomenon in the process. In current work ultrasound was applied above and below the membrane surface to reduce fouling after removing temperature effect. A hydrophilic mixed cellulose ester membrane with pore size of 0.45 μm was used in lab scale flat sheet module. Membrane module was placed above and below the ultr...

In this paper we present a rigid registration approach for 4D ultrasound (US) datasets, where images are registered over time. The 3D registration approach preceding the 4D registration consists of two main steps block-matching and outlier rejection. The outlier rejection step removes the spurious matchings’ from the block-matching module and ensures inverse consistency. For 4D registration, we...

Objective- The aim of this study was to obtain first time diagnosis of pregnancy and study of fetal development in different times of pregnancy period. Design- ِDescriptive study. Animals- 8 pregnant Markhoz goats. Procedure- 2D ultrasound was performed from day 25 to 130 of gestation, twice in week from day 25 to 70 and once in week from day 70 to 130 of gestation on eight goa...

Since the rose water is used in food, pharmaceutical, and cosmetic products, its microbiological control is necessary. Conventional pasteurization methods cause undesirable changes in taste, smell, medicinal properties and nutritional value with decreasing the amount of essential oil, because of high temperatures. In this study, the effects of the microwave power, temperature, ultrasound power,...

This paper presents a new robotic mechanism for ultrasound imaging. The device is placed on a patient's body by an operator, and an ultrasound expert controls the motions of the device to obtain ultrasound images. The paper focuses on the robotic mechanism that performs ultrasound imaging. The design of the mechanism is based on two approaches to produce center of motion for an ultrasound probe...
