Abstract This work presents a novel hardware configuration for radiotherapy systems to enable fast 3D X-ray imaging before and during treatment delivery. Standard external beam radiotherapy linear accelerators (linacs) have a single X-ray source and

Objectives: Cone beam computed tomography (CBCT) imaging is becoming an indispensable intraoperative tool; however, the current field of view prevents visualization of long anatomical sites, limiting clinical utility. Here, we demonstrate the longitu

Background and purpose We present the first implementation of Adaptive 4D cone beam CT (4DCBCT) that adapts the image hardware (gantry rotation speed and kV projections) in response to the patient’s real-time respiratory signal. Adaptive 4DCBCT was

Estudios recientes dentro de los miembros neotropicales de Gnaphaliinae (Gnaphalieae, Asteraceae), especialmente aquellos que utilizan secuencias de ADN, han servido para refinar los límites genéricos putativos y aclarar la clasificación dentro de
