Multi-object imaging can obtain more comprehensive information to analyze the surrounding environment better and is widely used in many fields. While most multi-object imaging methods require objects not to be coaxial, which must ensure that each object is within the line-of-sight (LOS) of beam progression. In this paper, we present an approach for imaging multiple coaxial objects utilizing an Airy beam array, which can see hidden objects and is conducive to expanding the range of information perception. The feasibility of our scheme is verified through numerical simulations and experiments, and the imaging capability influenced by the axial distance and size of objects is studied. In addition, the minimum imaging distance of the imaging system is also derived. The results will open new ideas for non-line-of-sight (NLOS) imaging and may find applications in queue target imaging.

White matter hyperintensity (WMH) is associated with cognitive impairment. In this study, 79 patients with WMH from hospital 1 were randomly divided into a training set (62 patients) and an internal validation set (17 patients). In addition, 29 WMH patients from hospital 2 were used as an external validation set.

Background And Objective: Our objective was to evaluate the agreement between micro-ultrasound, MRI and pathological tumor and prostate volume.
Methods: Retrospective analysis of consecutive prostate cancer patients with MRI and micro-ultrasound diagnostic assessment who subsequently underwent radical prostatectomy. Tumor and prostate volume on micro-ultrasound and MRI imaging calculated by a dedicated software were compared to those of the prostatectomy specimen.

Statement Of Problem: The precision and accuracy of intraoral scanners for complete arch implant scanning is questionable as it is affected by the absence of anatomic features, the presence of large homogenous areas, and the lack of clear reference points, all of which create inherent errors in the image stitching process by the scanner software program.
Purpose: The purpose of this in vitro study was to test a newly designed scan-aid apparatus for evaluating the effect of geometric heterogeneity and additional reference points on the time efficiency and scanning precision of complete arch implant scanning.
Material And Methods: A total of 60 scans (20 per group) were performed using an intraoral scanner in 3 different clinical simulations: 2 parallel implants, 4 parallel implants, and 4 implants; 2 anterior implants in parallel axial orientation; and 2 distal implants with a 30-degree posterior inclination.

Objective: Antibody-based therapy has emerged as a powerful tool for targeted treatment of neurological diseases, such as brain cancer and neurodegenerative disorders. However, direct, scalable, and safe confirmation of antibody delivery into the brain remains challenging. Antibodies can be effectively tracked when tagged with molecules that are detectable by medical imaging modalities, such as MRI, PET, or SPECT.
