Volume Imaging in Fluoroscopy

Modern Fluoroscopy Imaging Systems

Fluoroscopy, or real-time projection X-ray imaging, has been in clinical use since shortly after Roentgen’s discovery of X-rays. Early fluoroscopes consisted simply of an X-ray source and a fluorescent screen, between which the patient was placed. After passing through the patient, the remnant beam impinged upon the fluorescent screen and produced a visible glow, which was directly observed by ...

Quantification of partial volume effects in planar imaging

Introduction: The limited resolution of the imaging system causes partial volume effects (PVEs). These results in spreading of image counts to the neighboring pixels. This phenomenon is called spill-out effect. This study aimed at quantifying PVEs using ImageJ. Methods:Technetium-99m solution of concentration of 74 kBq/ml was filled into spheres A, B<...

CT angiography-fluoroscopy fusion imaging for percutaneous transapical access.

OBJECTIVES The aim of this proof-of-principle study is to validate the accuracy of fusion imaging for percutaneous transapical access (TA). BACKGROUND Structural heart disease interventions, including TA, are commonly obtained under fluoroscopic guidance, which lacks important spatial information. Computed tomographic angiography (CTA)-fluoroscopy fusion imaging can provide the 3-dimensional ...
