A comparison of normalization effects on three whole-body cylindrical 3D PET systems.
Published in Physics in Medicine and Biology
Normalization coefficients in three-dimensional positron emission tomography (3D PET) are affected by parameters such as camera geometry and the design and arrangement of the block detectors. In this work, normalization components for three whole-body 3D-capable tomographs (the GE Advance, the Siemens/CTI962/HR+ and the Siemens/CTI951R) are compare...
Impella 2.5 assisted balloon aortic valvuloplasty and percutaneous coronary intervention as a bridge to heart transplant...
Published in The Journal of invasive cardiology
Percutaneous left ventricular assist device (pLVAD) utilization is increasing as the potential applications expand. We report a case of high-risk balloon aortic valvuloplasty and percutaneous coronary intervention using the Impella 2.5 pLVAD in a patient with severely depressed left ventricular function as a bridge to heart transplantation.
Use of positron emission tomography in oncology and its potential role to assess response to imatinib mesylate therapy i...
Published in European Journal of Cancer
The reliability of established anatomical imaging techniques, such as computed tomography (CT) and magnetic resonance imaging (MRI), is compromised in following response to certain types of treatment if metabolic improvement occurs before morphologic change is apparent. Thus, traditional imaging techniques cannot discriminate early tumor response b...
Spatial distortion correction and crystal identification for MRI-compatible position-sensitive avalanche photodiode-base...
Published in IEEE Transactions on Nuclear Science
Position-sensitive avalanche photodiodes (PSAPDs) are gaining widespread acceptance in modern PET scanner designs, and owing to their relative insensitivity to magnetic fields, especially in those that are MRI-compatible. Flood histograms in PET scanners are used to determine the crystal of annihilation photon interaction and hence, for detector ch...
A technique for hemostasis and closure after percutaneous aortic valve replacement.
Published in Catheterization and Cardiovascular Interventions
Access closure is the key to successful retrograde percutaneous aortic valve replacement. It requires large-bore femoral arterial access (18-28F) which most operators manage with surgical access and closure under general anesthesia. We report a case example of how, using our center s peripheral interventional experience, we have developed a techniq...
Radiation risks to personnel and public during the treatment of malignant glioma using interstitial brachytherapy.
Published in British Journal of Radiology
125I seeds are used in brachytherapy for the treatment of malignant gliomas. The use of such radioactive sources is associated with a certain radiological hazard to both personnel and members of the public. This hazard should be quantified so that the ALARA principle of radiological protection may be implemented satisfactorily. A study was undertak...

Using global illumination in volume visualization of rheumatoid arthritis CT data.
Published in IEEE Computer Graphics and Applications
Proper lighting in rendering is essential for visualizing 3D objects, but most visualization software tools still employ simple lighting models. The advent of hardware-accelerated advanced lighting suggests that volume visualization can be truly usable for clinical work. Researchers studied how volume rendering incorporating global illumination imp...
