Toward CT-Equivalent Image Quality in Low-Dose Radiotherapy Planning: Conditional Diffusion-Based CBCT-to-CT Synthesis and the Impact of CBCT Input Representation
Alzahra Altalib, Chunhui Li, Christopher Hamill Taylor +2
During standard radiotherapy planning, repeated CT acquisitions are often required for patient registration, verification, and adaptive planning, resulting in increased cumulative…
Dual-Domain Equivariant Generative Adversarial Network for Multimodal CT-PET Synthesis
Gabriel Steele, Alzahra Altalib, Alessandro Perelli
We present a Dual-Domain Equivariant Generative Adversarial Network (DDE-GAN) for multimodal CT-PET image synthesis. Traditional GAN-based approaches often operate solely in the sp…
ExoplaNeT accRetion mOnitoring sPectroscopic surveY (ENTROPY) III. Optical He I line profiles of the accreting super Jupiter Delorme 1 (AB)b
Gayathri Viswanath, Mickaël Bonnefoy, Catherine Dougados +8
High-resolution spectroscopic observations of helium emission lines provide a powerful probe of accretion geometry in classical T Tauri stars, revealing regions not well traced by…
FunduSegmenter: Leveraging the RETFound Foundation Model for Joint Optic Disc and Optic Cup Segmentation in Retinal Fundus Images
Zhenyi Zhao, Muthu Rama Krishnan Mookiah, Emanuele Trucco
Purpose: This study introduces the first adaptation of RETFound for joint optic disc (OD) and optic cup (OC) segmentation. RETFound is a well-known foundation model developed for f…
Lithium and the evolution of intermediate-mass T Tauri and Herbig stars. Rotation, accretion, and planets
I. MendigutÃa, J. Campbell-White, B. Montesinos +9
(Abridged) We contribute to our understanding of the evolution of young intermediate-mass stars by providing a comprehensive analysis of their lithium (Li) content. A sample of 71…
Stability analysis of time-periodic shear flow generated by an oscillating density interface
Lima Biswas, Anirban Guha
We consider the conceptual two-layered oscillating tank of Inoue & Smyth (2009), which mimics the time-periodic parallel shear flow generated by low-frequency (e.g. semi-diurnal ti…
