To address the growing demand for temperature control precision and uniformity in wafer processing, a specialized electrostatic chuck temperature control system based on thermal control coatings is proposed, aiming to enhance thermal management robustness and homogeneity. This study employs a zoned control methodology using metal-oxide conductive coatings on silicon carbide wafer heating plates. A quadrant-based thermal control coating model was established, and finite element analysis was conducted to compare temperature distribution characteristics across three geometric configurations: sectorial, spiral, and zoned designs.

Purpose: Compared with retrospective ECG-gated arterial phase scan, to investigate the clinical application value of dual-source CT large-spiral arterial late scan in the imaging evaluation of left atrial appendage (LAA).
Patients And Methods: A total of 108 patients requiring LAA CT angiography (CTA) due to atrial fibrillation (AF) were selected from September 2024 to December 2024, including 52 patients in group A (Flash large-spiral arterial late scan) and 56 patients in group B (retrospective ECG-gated arterial phase scan). All patients underwent double-phase scan.

Purpose: To develop a method for abdominal simultaneous 3D water ( ) and ( ) mapping with isotropic resolution using a free-breathing Cartesian acquisition with spiral profile ordering (CASPR) at 3 T.
Methods: The proposed data acquisition combines a Look-Locker scheme with the modified BIR-4 adiabatic preparation pulse for simultaneous and mapping. CASPR is employed for efficient and flexible k-space sampling at isotropic resolution during free breathing.

Objective: This study aimed to characterize the association between pulmonary embolism (PE) onset and various anti-tumor therapeutic approaches in patients with lung cancer, with the goal of identifying potential high-risk populations.
Methods: A retrospective analysis was conducted on clinical records from 2019 to 2025, among the 84,000 inpatients with lung cancer, 106 patients developed PE during hospitalization for anti-tumor treatment, who were confirmed using spiral computed tomography (CT) or pulmonary angiography per CTS (2018) and NEJM (2010) criteria. Data were collected on patient demographics, cancer staging, treatment type, and time to PE onset.
