X-ray projection imaging of metal oxide particles inside gingival tissues
Jarrod N. Cortez, Ignacio O. Romero, Md Sayed Tanveer +7
There is increasing recognition that oral health affects overall health and systemic diseases. Nonetheless it remains challenging to rapidly screen patient biopsies for signs of in…
Correlation between X-ray tube current exposure time and X-ray photon number in GATE
Ignacio O. Romero, Yile Fang, Changqing Li
The image quality of X-ray imaging relies heavily on the X-ray output number which is dependent on the X-ray tube current and the exposure time. Hybrid X-ray imaging modalities lik…
Radiation dose estimation in pencil beam x-ray luminescence computed tomography imaging
Ignacio O. Romero, Changqing Li
Pencil x-ray beam imaging provides superior spatial resolution than other imaging geometries like sheet beam and cone beam geometries due to the illumination of a line instead of a…
X-ray fluorescence computed tomography (XFCT) imaging with a superfine pencil beam x-ray source
Ignacio O. Romero, Yile Fang, Michael Lun +1
X-ray fluorescence computed tomography (XFCT) is a molecular imaging technique of x-ray photons, which can be used to sense different elements or nanoparticle (NP) agents inside de…
A feasibility Study of Time of Flight Computed Tomography for Breast Imaging
Ignacio O. Romero, Changqing Li
Cone beam computed tomography (CBCT) for breast imaging has potential to replace conventional mammograms. However, concerns over dose and image quality prevent CBBCT systems from t…
