O movimento da Lua tem aspectos pouco intuitivos quando observado de um referencial fixo no Sol. Existem muitas concepções errôneas sobre esse movimento, encontradas em vários textos de referência e aceitas pela maioria das pessoas como parte do senso ...

Multi‐institutional study on image quality for a novel CBCT solution on O‐ring linac
Abstract Introduction This work presents a multi‐institutional study on image quality provided by a novel cone beam computed tomography (CBCT). The main goal is to investigate the consistency of imaging performance across multiple institutions.

Motion Estimation and Correction in Photoacoustic Tomographic Reconstruction [PDF]
Motion, e.g., due to patient movement or improper device calibration, is inevitable in many imaging modalities such as photoacoustic tomography (PAT) by a rotating system and can lead to undesirable motion artifacts in image reconstructions, if ignored. In this paper, we establish a hybrid-type model for PAT that incorporates motion in the model.

Abstract Background Volumetric modulated arc therapy (VMAT) requires an accurate patient‐specific quality assurance (PSQA) program. In clinical practice, this is usually performed using the γ‐index and the two‐dimensional gamma passing rate (2D %GP). A three‐dimensional (3D) index incorporating the patient anatomy could be more useful for the 3D dose ...

Abstract Purpose Single‐isocenter multitarget (SIMT) radiosurgery has become increasingly popular as advancement in planning and delivery systems have made this approach clinically viable. With targets varying in size and distance from isocenter, SIMT plans are highly complex with dynamic multileaf collimator (MLC) motion.

Motion Dreamer: Boundary Conditional Motion Reasoning for Physically Coherent Video Generation [PDF]
Recent advances in video generation have shown promise for generating future scenarios, critical for planning and control in autonomous driving and embodied intelligence. However, real-world applications demand more than visually plausible predictions; they require reasoning about object motions based on explicitly defined boundary conditions, such as ...

Abstract Purpose Palliative radiotherapy comprises a significant portion of the radiation treatment workload. Volumetric‐modulated arc therapy (VMAT) improves dose conformity and, in conjunction with flattening filter free (FFF) delivery, can decrease treatment times, both of which are desirable in a population with a high probability of retreatment ...

Physical simulation of glacier motion modes
Modes of «dry friction» at glacier-bedrock interface (ice sliding and flow) were simulated under uniform compression with different combinations of mechanical and thermodynamic factors. Effect of ice structure in the intermediate layer was considered in terms of strength of ice adhesion to complex-shaped substrate for typical cases: at frictional ...
