Cell Segmentation Beyond 2D—A Review of the State‐of‐the‐Art

Advanced Intelligent Discovery, EarlyView.
Cell segmentation underpins many biological image analysis tasks, yet most deep learning methods remain limited to 2D despite the inherently 3D nature of cellular processes. This review surveys segmentation approaches beyond 2D, comparing 2.5D and fully 3D methods, analyzing 31 models and 32 volumetric datasets, and introducing a unified reference ...

Nongated Photon‐Counting Computed Tomography Angiography Detects Cardioembolic Stroke Sources and Thoracic Pathology: A Retrospective Cohort Study

Stroke: Vascular and Interventional Neurology
BACKGROUND Stroke is often attributable to cardiothoracic factors, but the need for ECG gating and limited spatial resolution on conventional computed tomography often limits the detection of pathology relevant for secondary stroke prevention.

Healing Following Endoscopic Reconstruction of the Anterior Skull Base in Patients With Sinonasal Malignancies

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Healing dynamics after anterior skull base (ASB) reconstruction following transnasal endoscopic surgery (TES) for sinonasal malignancies remain poorly characterized. This study aimed to describe the postoperative healing process, quantify time to healing, identify factors influencing healing, and assess radiologic evolution over ...

Development of a Photon Counting X-ray CT System for the Material Identification [PDF]

, 2013
The purpose of our research is to develop a photon counting X-ray CT system for the material identification. We developed a new CdTe detector that was able to measure x-rays with the count rate of 107 counts/sec/m㎡ with four energy windows. The size of a
