A novel adaptive apodization to improve the resolution of phased subarray imaging in medical ultrasound

ConclusionApplying the proposed ADAP, besides conventional compounding in PSA imaging, leads to improvement of both the resolution and contrast compared to PHA imaging.

Conclusion: Using thermal models deduced from low-powered test sonications, the proposed MPC algorithm provides good performance in phantoms. In direct comparison to the current state-of-the-art hyperthermia controller, MPC performs better due to the more finely tuned heating patterns and therefore constitutes an important step toward stable, uniform hyperthermia.

Alarcon-Rojo, Luis Carrillo-Lopez, Ivan Garcia-Galicia, Mariana Huerta-Jimenez, Larysa PaniwnykAbstractQuality of bovine longissimus lumborum, infraspinatus and cleidooccipitalis muscles after high-intensity ultrasound (HIU; 40 kHz and a power of 11 W/cm2 for 0, 40, 60, and 80 min) and aging (0, 7 and 14 d) was evaluated. The effects of HIU on pH and color of meat were not considered negative. HIU improved water holding capacity (WHC) of l. lumborum and infraspinatus only after aging. Whereas, the WHC ...

This review aimed to highlight recent results of techno-functional (e.g., water and oil holding capacities, foaming capacity and stability, emulsifying activity, emulsion stability, rheological and pasting properties, and tin corrosion inhibitory activity) and biofunctional (e.g., antioxidant, antiradical, antiglycation, anticoagulant, antitumor, ...

This study aims to assess whether ultrasound-guided injection of platelet-rich plasma can safely and effectively treat symptoms associated with acetabular hip labral tears. Design Institutional review board approval was gained for a prospective study of eight patients (N = 8), who have previously failed conservative management, to receive ultrasound-guided injection of platelet-rich plasma at the site of hip labrum tear. We assessed pain reduction and functional ability at baseline and then 2, 6, and 8 wks after injection, using the visual analog scale and Harris Hip Score, respectively. Results Statistically signifi...

Introduction Ozone has been recently used as a safe alternative treatment in musculoskeletal disorders with fewer adverse effects than corticosteroids. The aim of this study was to compare the efficacy of a single injection of ozone with that of a corticosteroid in the treatment of shoulder impingement. Design Thirty patients with shoulder pain and clinical signs and symptoms of impingement were randomly assigned into two groups: ultrasound-guided injection with ozone or corticosteroid. Patients’ symptoms were evaluated by visual analog scale, constant score, shoulder pain and disability scale, shoulder range of...

We describe a case of posttraumatic chronic intercostal neuralgia, in which successful pain relief was achieved via repeated injections of local anesthetic and steroid combinations in the serratus anterior plane under ultrasonographic guidance. This novel technique is easy to administer, reliable, and warrants further investigation with regard to its use for rehabilitation of patients who are experiencing posttraumatic chronic neuropathies of the chest wall.
