چکیده
Computational Methods of Ultrasound Wave Propagation in Healing Long Bones D. I. Fotiadis1 Summary Quantitative ultrasound has attracted significant interest in the evaluation of bone fracture healing. Animal and clinical studies have demonstrated that the propagation velocity across fractured bones can be used as an indicator of healing. Researchers have recently employed computational methods for modeling wave propagation in bones aiming to gain insight into the underlying mechanisms of wave propagation and to further enhance the monitoring capabilities of ultrasound. In this paper we review the computational studies of ultrasound wave propagation in intact and healing bones.

Computational Modeling of Ultrasound Wave Propagation in Healing Bones
Computational studies have recently gained significant interest in engineering applications for the virtual monitoring of bone pathologies such as osteoporosis and fracture healing. Several authors have investigated numerically the role of quantitative ultrasound as a diagnostic and monitoring tool of the fracture healing process since ultrasonic techniques are non-invasive and non-ionizing mea...
متن کاملUltrasonic Evaluation of Intact, Healing and Osteoporotic Long Bones
Quantitative ultrasound (QUS) has been introduced in recent years for the comprehensive noninvasive and non-ionizing evaluation of bones. This paper presents a review of our research work of the last decade including experimental and computational studies for the ultrasonic assessment of fracture healing and osteoporosis. The axial transmission and the backscattering methods have been applied t...
متن کاملClinical experiences with ultrasonometric measurement of fracture healing.
INTRODUCTION The use of noninvasive, acoustic methods like ultrasonometry is becoming increasingly interesting in the quantitative assessment of fracture healing. A reliable measurement technique has been described using ultrasonic transducers placed across the fracture gap. Ultrasonic image aiming is useful for accurate transducers location, on both sides of the gap. The study was designed to ...
متن کاملInfluence of the osteosynthesis plate on ultrasound propagation in the bone
OBJECTIVE To analyze the influence of steel plates for osteosynthesis on the velocity of ultrasound propagation (VU) through the bone. METHODS The transverse coronal and sagittal velocity of ultrasound propagation underwater were measured on the intact bone and then on assemblies of the same bone with two types of osteosynthesis plates (DCP and semi tubular), fixed onto the dorsal side of the...
متن کاملTHE BEST DURATION OF LOW INTENSITY PULSED ULTRASOUND FOR ACCELERATING FRACTURED-RADIAL BONE REPAIR
We have already shown that low intensity pulsed ultrasonic treatment increases rabbit radial fracture healing. The present experiment was undertaken to find out the best duration for treatment. A complete transverse fracture was made in the right radial bones of21 adult male rabbits by a Stanley knife. The animals were divided into 4 groups: group 1, control groups 2, 3, and 4, experimental...
