Adaptive MR-guided Stereotactic Body Radiation Therapy (MRg-SBRT) is an effective treatment for malignant pancreatic lesions. However, its implementation may be hindered by the presence of implants with scanning conditions interd...

The study aims to develop a parameterized brachytherapy source geometry modeling framework for GPU-based Monte Carlo particle transport simulation with an integrated DICOM workflow.

Proton therapy offers superior therapeutic ratio due to its favorable dose distribution, but accurate dose calculation remains challenging. Current methods rely on either pencil-beam algorithms (fast but inaccurate in heterogeneo...

Cherenkov imaging provides valuable beam delivery information, but fixed treatment camera positions are subject to gantry occlusions and couch rotation artifacts that inhibit imaging for a significant percentage of clinical cases...

To upgrade the ADAM breathing phantom to include a female version, MADAM, featuring a thoracic cavity with breasts and a realistically-shaped heart. This design enables verification of breast radiotherapy treatments, broadening i...

Current Y-90 radioembolization (RE) standard dosimetry assumes homogeneous microsphere distribution, ignoring patient-specific vasculature heterogeneity. We developed a framework to reproduce and augment patient-specific hepatic...

Personalized Ultra-Fractionated Stereotactic Adaptive Radiotherapy (PULSAR) delivers high-dose radiation pulses separated by intervals of several weeks, enabling tumor response–guided adaptation, reduced toxicity, and potential s...

Existing "one-size-fits-all" approaches in PSMA radiopharmaceutical therapies (RPTs) fail to account for critical inter-patient variabilities, risking under- or over-treatment. To address this, we are developing theranostic digit...

Jaw geometry in elongated fields substantially impacts output factors (OPFs); therefore, reliance on square-field data alone cannot account for the physical effects. This study evaluated the response characteristics of various sm...

Ionization chambers represent the gold standard for clinical dosimetry; however, they suffer from severe ion recombination losses at the ultra-high dose rates (UHDR) characteristic of FLASH radiotherapy. This study evaluates the...

To develop and characterize a novel polymer gel dosimeter for 3D radiation dosimetry. This study introduces a formulation based on polyvinyl alcohol (PVA) and acrylic acid (ACA), with the inclusion of glucose as an organic sensit...

Photon-counting-detector (PCD) CT acquires multi-energy data in a single scan, enabling quantitation of electron density (ρe) and effective atomic number (Zeff). This study assessed the performance of PCD-CT for ρe and Zeff mappi...

to evaluate performance of Elekta Unity 1.5T MR-Linac Comprehensive Motion Management (CMM) system across multiple gating strategies and anatomical sites: gastrointestinal(GI), genitourinary(GU), and thoracic(lung). This work aim...

During radiotherapy for nasopharyngeal carcinoma, patients frequently experience anatomical variations, leading to discrepancies between the delivered and planned doses. Adaptive radiotherapy (ART) can compensate for these deviat...

To investigate whether PET-defined metabolic subregions within lung tumors exhibit distinct CT radiomic characteristics, enabling a spatially imaging-based assessment of intratumoral heterogeneity.

Adaptive radiotherapy (ART) and personalized ultra‑fractionated stereotactic adaptive radiotherapy (PULSAR) require longitudinal anatomical modeling, deformable image registration (DIR), and dose recalculation and accumulation. W...

To assess the effectiveness of a developmental anchor point tracking algorithm with PET deblurring in targeting tumors on the RefleXion X2 platform.

Proton density fat fraction (PDFF) is widely used as a quantitative MRI biomarker in clinical care. Accurate PDFF measurement requires robust quality control, commonly performed using phantom-based assessment. This work evaluates...

To assess the impact of parameters on CT gout identification

Time-resolved singlet oxygen luminescence detection (TSOLD) enables direct measurement of singlet oxygen generation during photodynamic therapy (PDT), while multispectral SOLD (MSOLD) and singlet oxygen explicit dosimetry (SOED)...

FLASH radiotherapy reduces skin damage in vivo from ultra-high dose rate (UHDR) irradiation relative to conventional dose rates (CDR), while preserving tumor tissue damage. The macroscopic FLASH tissue sparing effect has not yet...

CT X-ray spectra were generated in PHITS by simulating bremsstrahlung at the tube anode. Using the resulting continuous CT spectrum as the incident beam, silicon response was evaluated for silicon thicknesses of 1, 5, and 10 mm t...

This study was to examine the complimentary damage mechanisms and their potential synergy between conventional/ultrahigh dose rate radiotherapy (CDR/UHDR RT) and photodynamic therapy (PDT). FLASH radiotherapy produces a significa...

The Gamma-Emitter Contamination Assessment Tool (GECAT) is a software application designed to perform in-field radiological triage. The application relies on detector count rate efficiency data generated by performing Monte Carlo...
