A mathematical model of the biomechanics human respiration has been developed. To verify proposed model, it is suggested to use a photo-optical method for recording chest and abdomen together with spirometry. Pilot studies were carried out among 10 men aged 20–22. The body mass index subjects ranged from 19.3 21.5 kg/m², height – 169 182 cm, weight 55 70 kg. Correlation-regression analysis resu...

Accurate estimation of hydrocarbon volume in a reservoir is important due to future development and investment on that reservoir. Estimation of Oil and Gas reservoirs continues from exploration to end of reservoir time life and is usual upstream engineer’s involvements. In this study we tried to make reservoir properties models (porosity and water saturation) and estimate reservoir volume hydro...

Accurate estimation of kidney volume is essential for clinical diagnoses and therapeutic decisions related to renal diseases. Existing kidney volume estimation methods rely on an intermediate segmentation step that is subject to various limitations. In this work, we propose a segmentation-free, supervised learning approach that addresses the challenges of accurate kidney volume estimation cause...

Thick-slice image acquisitions are sometimes inevitable in magnetic resonance imaging due to limitations posed by pulse sequence timing and signal-to-noise-ratio. The estimation of an isotropic high-resolution volume from thick-slice MRI scans is desired for improved image analysis and evaluation. In this article we formulate a maximum a posteriori (MAP) estimation algorithm for high-resolution...

Due to the finite spatial resolution of imaging devices, a single voxel in a medical image may be composed of mixture of tissue types, an effect known as partial volume effect (PVE). Partial volume estimation, that is, the estimation of the amount of each tissue type within each voxel, has received considerable interest in recent years. Much of this work has been focused on the mixel model, a s...

This document describes the three-dimensional reconstruction of the internal and external surfaces of the human’s left ventricle from actual SPECT data. The reconstruction is a first process fitting in a complete VR application that will serve as an important diagnosis tool for hospitals. Beginning with the surfaces reconstruction, the application will provide volume and interactive real-time m...

This paper describes technology (hardware and software) that has been developed to estimate the volume of material contained within the tray of various haul trucks. Such information is critical to truck utilization and thus can provide information that could lead to significant gains in productivity. The system consists of a field computer and two proximity lasers. The lasers are placed high ab...
