Unsupervised X-Ray-to-DRR Translation with Structural Enhancement for Efficient X-Ray-to-CT Registration

Peijie Jiang, Long Lei, Shaolin Lu, Yi Yang et autres

Artifacts and geometric distortions arising from modality differences are major sources of mismatch between conventional CT-based digitally reconstructed radiographs (DRRs) and real X-ray images. We propose an unsupervised crossmodal image translation framework that maps X-ray images to DRRs, enhancing structural features in …

Improving Atomic Layer Deposition Process of Silicon Oxide (SiO 2 ) With Single and Double Pulse Processes

Long Lei, Pauline Dill, E. Schumann

Due to hardly known film properties, precursor savings and hardware modifications of the atomic layer deposition (ALD) equipment, the bis(diethylamino)silane (SiBDEA)/ozone-oxygen (O₃/O₂) silicon oxide (SiO₂) process requires re-optimization. Using design of experiments (DoE), the old double pulse (ODP) process was transformed into …

Robotic Respiratory Liver Motion Compensation for Stable Ultrasound Imaging of Small Lesions

Long Lei, Yingying Han, Jinhang Li, Ziwen Wang et autres

Real-time ultrasound-guided percutaneous liver biopsy plays a crucial role in diagnosing early liver cancer. However, patient respiration can cause liver drift, causing small target lesions to deviate from the ultrasound imaging plane and become invisible, complicating accurate punctures. To address this, we …

Improving Atomic Layer Deposition Process of Silicon Oxide (SiO2)

Long Lei, Pauline Dill, E. Schumann

Due to film uniformity issues and material wastage caused by changes in the hardware setup of the atomic layer deposition (ALD) equipment, the bis(diethylamino)silane (SiBDEA))ozone oxygen mixture ($\mathrm{O}_{3} / \mathrm{O}_{2}$) silicon oxide (SiO2) process of this equipment needs to be re-optimized urgently. …
