The ongoing COVID-19 pandemic has already affected more than 300 million people worldwide. Medical imaging shortage affects an estimated of 4 billion people, especially in rural and remote areas (RAs), limiting diagnostic assessment of respiratory illness. Lung ultrasound imaging (LUS) together with volume sweep imaging (VSI) acquisition protocols have been successfully piloted as a solution for lung screening in RAs eliminating the need for trained operators and on-site radiologists. Nevertheless, this protocol requires the acquisition of 12 videos for 6 areas with both longitudinal and transverse positions of the transducer. Nonetheless, bandwidth limitations can hamper the transmission of these videos for remote interpretation. This work aimed to developed a stitching algorithm capable of generating a panoramic reconstruction of LUS cine clips. The results show reconstructions with minimal loss of information as 92.5% of the panoramic images conserved the presence of A-lines. These results show that LUS can be represented as an image without significantly compromising its quality. This can be useful to overcome bandwidth issues as well as improve the time on lung assessment of the patient.

CBCT-Based Analysis of Factors Influencing the Quality of New Bone Formation Following Mandibular Distraction Osteogenesis in Children With Pierre Robin Sequence.

The aim of this study was to explore the factors influencing the quality of new bone formation after distraction osteogenesis in children with Pierre Robin sequence (PRS). Using cone-beam computed tomography (CBCT), bone density relative grayscale values of the region of new bone formation before and 3 to 4 months after mandibular distraction osteogenesis (MDO) were measured in 80 children with PRS, and correlation analysis was conducted with the potential clinical influencing factors of the children. CBCT reconstruction of the panoramic film showed that the new bone formation was good at 3 to 4 months after MDO.

Background: Fibrous dysplasia (FD) is a self-limiting benign disease with slow progression in which the normal bone is replaced by dysplastic fibrous tissue. The craniofacial skeleton is one of the most commonly affected areas, and it can create unique challenges in dental implant therapy. This case aims to report an unusual presentation of FD localized in the alveolar crest bone of the edentulous site, causing special obstacles to implant placement, and provide a diagnostic and treatment process that may be referenced.

Background: The collum angle, tooth dimensions, root length, and alveolar bone thickness have a significant impact on orthodontic diagnosis and treatment planning. The boundaries of orthodontic tooth movement are determined by alveolar bone thickness and dimensions while the collum angle determines the appropriate positioning of the root relative to the cortical plate. This study aimed to compare the collum angle, crown dimensions, root length, and alveolar bone thickness of the upper and lower incisors, canines, and premolars in subjects with varying anteroposterior relationships.

Article Synopsis
- Researchers are developing artificial compound eyes (CE) modeled after arthropods to improve imaging technology, but current designs have issues with defocusing when used with standard CMOS cameras.
- A new compact camera inspired by South American shrimps utilizes a deep learning method to achieve clear wide-field imaging without complex hardware, significantly simplifying its design.
- The innovative camera, weighing only 5.4g and measuring 3 x 3 cm, shows superior resolution and 3D trajectory tracking, making it suitable for applications in nano-optics, medical endoscopy, and robotics.
A single-center trial of electrographic flow mapping and concomitant voltage mapping in sinus rhythm and atrial fibrillation (FLOW EVAL-AF).

Article Synopsis
- Electrographic flow (EGF) mapping is a technique used to understand how electrical signals move in the heart's atria, especially in relation to atrial fibrillation (AF) compared to normal sinus rhythm (SR).
- The study involved mapping electrical activity in the atria of ten patients, showing that EGF patterns differ significantly in AF, with lower electrographic flow consistency (EGFC) during AF compared to SR, indicating more chaotic activity.
- The findings suggest EGFC could serve as a valuable marker for assessing atrial health and myopathy, correlating with bipolar voltage measurements, which are commonly used to evaluate heart conditions.
