Possibility and Reproducibility of Renal Assessing and Size Measurement by Three- Dimensional vs Two- Dimensional Ultrasounographv in Dogs
Objective- To determine the possibility and reproducibility of three-dimensional ultrasonography (3DUS)and comparison of the achieved measurements to normal two-dimensional ultrasonography (2DCS)Design- Descriptive studyAnimals- 10 young mixed normal dogs, age 1.5-2.5 year, weighing 9.7-12 kg Procedure- Renal width, length, and depth measured in coron al and transverse sections. The measurement...

15 صفحه اولAssessing the accuracy and reliability of ultrasonographic three-dimensional parathyroid volume measurement in a patient with secondary hyperparathyroidism: a comparison with the two-dimensional conventional method
PURPOSE The purpose of this study was to investigate the accuracy and reliability of the semi-automated ultrasonographic volume measurement tool, virtual organ computer-aided analysis (VOCAL), for measuring the volume of parathyroid glands. METHODS Volume measurements for 40 parathyroid glands were performed in patients with secondary hyperparathyroidism caused by chronic renal failure. The v...
متن کاملThree Dimensional Stability Analysis of a Liquid Propellant Combustor
A theoretical study analyzing three-dimensional combustion acoustic instabilities in a liquid propellant rocket engine combustor has been conducted. A linear theory based on Crocco’s pressure sensitive time lag model is used. To apply this theory the combustor is divided into two main components, including the combustion chamber and the converging part of the nozzle. The assumption of concentra...
متن کاملComputer-aided-design-model-assisted absolute three-dimensional shape measurement.
Conventional three-dimensional (3D) shape measurement methods are typically generic to all types of objects. Yet, for many measurement conditions, such a level of generality is inessential when having the preknowledge of the object geometry. This paper introduces a novel adaptive algorithm for absolute 3D shape measurement with the assistance of the object computer-aided-design (CAD) model. The...
