Analytical model of prompt gamma timing for spatiotemporal emission reconstruction in particle therapy [0.03%]
Julius Werner,Malte Schmidt,Francesco Pennazio et al.
Julius Werner et al.
Objective: Particle therapy relies on up-to-date knowledge of the stopping power of the patient tissues to deliver the prescribed dose distribution. The stopping power describes the average particle motion, which is encod...

Ionizing radiation is a major source of biological hazard, bearing a broad range of detrimental lesions of the DNA structural and molecular integrity - often leading to genomic instabilities and severe cellular outcomes. The sensitivity of ...
Unraveling the role of boron microdistribution in BNCT dosimetry of glioblastoma multiforme: combined theoretical and experimental insights [0.03%]
Barbara Marcaccio,Agustina Mariana Portu,Gustavo A Santa Cruz et al.
Barbara Marcaccio et al.
Objective: Boron Neutron Capture Therapy is a cancer radiotherapy that uses the selective uptake of boron compounds by tumor cells, followed by neutron irradiation. Conventional dosimetry generally assumes a homogeneous b...
Four-row MRI receive array with remote circuitry for improved parallel imaging in radiation therapy systems [0.03%]
Karthik Lakshmanan,Lindsay Phillips,Bili Wang et al.
Karthik Lakshmanan et al.
Objective.Previous MR guided radiation therapy (MRgRT) radiofrequency coil arrays have been limited to one to two rows of coils in the head-foot direction because of the desire to place radiation-opaque coil circuitry outside the window thr...

Reimund Bayerlein et al.
Objective: This work presents and evaluates a Monte Carlo-based scatter correction (SC) method developed for the Jagiellonian Positron Emission Tomography (J-PET) scanner, a modular PET system based on plastic scintillato...
Study of Gd beam filtration for dual-layer flat panel detector based CBCT imaging: proof-of-concept study with 160 mm diameter phantom [0.03%]
Xin Zhang,Yuhang Tan,Jiongtao Zhu et al.
Xin Zhang et al.
This study aims at evaluating the gadolinium (Gd) beam filter in generating high quality dual-energy cone beam CT (CBCT) images with a dual-layer flat panel detector (FPD).
Approach: First of all, the Cramer-Rao lower bounds (CRLBs) wer...
Development and characterisation of a radiobiology proton beamline using radiochromic film dosimetry [0.03%]
Carina Marques Coelho,Pablo de la Fuente Fernández,Paula Bononad et al.
Carina Marques Coelho et al.
Objective: To develop and optimise a dedicated low-energy proton beamline at the Centre for Micro-Analysis of Materials (CMAM, Madrid, Spain) for radiobiological applications. ...
Huijuan Peng,Yuting Liang,Shangyan Wei et al.
Huijuan Peng et al.
Objective: Current automatic segmentation models in radiotherapy, which are predominantly unimodal and image-based, have limited generalizability due to boundary ambiguity and the lack of guideline integration. This study...
Flow-QSM: bridging learned priors and physical models for quantitative susceptibility mapping [0.03%]

Haoming Qin
Objective: Quantitative Susceptibility Mapping (QSM) is a magnetic resonance imaging
technique that quantifies tissue magnetic susceptibility by solving an ill-posed inverse
problem from measured magnetic field pe...
Optimizing energy settings in CdTe, CZT, and Si photon-counting CT for material separation and detection [0.03%]
基于材料分离和检测的CdTe、CZT和Si光子计数CT能量设置优化研究
Mridul Bhattarai,Ehsan Abadi,Ehsan Samei
Mridul Bhattarai
Objective: The performance of photon-counting CT (PCCT) depends on how detector energy thresholds or bins (collectively referred to as energy settings) are defined. This study aimed to identify optimal energy settings for...
