ionizing radiation makes QUS a good screening tool to diagnose low bone density at the community level and supports the work done by Sharma et al.[1] Diagnosis of osteoporosis using QUS is practical and economical at the community level. This early diagnosis of osteoporosis would facilitate early initiation of pharmacotherapy and secondary preventive measures using patient education and physica...

PURPOSE The identification of tumor pathologic characteristics is an important part of breast cancer diagnosis, prognosis, and treatment planning but currently requires biopsy as its standard. Here, we investigated a noninvasive quantitative ultrasound method for the characterization of breast tumors in terms of their histologic grade, which can be used with clinical diagnostic ultrasound data....

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...

Ultrasound imaging is a widely used medical imaging modality. But the major issue with ultrasound images is the presence of speckle noise, which is an inherent limitation of ultrasound images. This research work focuses on speckle noise reduction in ultrasound images. Various predefined techniques for despeckling are studied thoroughly and a novel approach is proposed. In addition, comparison o...
