Quantification with a dedicated breast PET/CT scanner

Performance Evaluation of a New Dedicated Breast PET Scanner Using NEMA NU4-2008 Standards.

UNLABELLED The aim of this work was to evaluate the performance characteristics of a newly developed dedicated breast PET scanner, according to National Electrical Manufacturers Association (NEMA) NU 4-2008 standards. METHODS The dedicated breast PET scanner consists of 4 layers of a 32 × 32 lutetium oxyorthosilicate-based crystal array, a light guide, and a 64-channel position-sensitive phot...

Reduced-dose [F]-FDG PETCT scanning with current generation PETCT systems

Review of portable CT with assessment of a dedicated head CT scanner.

This article reviews a number of portable CT scanners for clinical imaging. These include the CereTom, Tomoscan, xCAT ENT, and OTOscan. The Tomoscan scanner consists of a gantry with multisection detectors and a detachable table. It can perform a full-body scanning, or the gantry can be used without the table to scan the head. The xCAT ENT is a conebeam CT scanner that is intended for intraoper...

Breast-Dedicated Radionuclide Imaging Systems.

Breast-dedicated radionuclide imaging systems show promise for increasing clinical sensitivity for breast cancer while minimizing patient dose and cost. We present several breast-dedicated coincidence-photon and single-photon camera designs that have been described in the literature and examine their intrinsic performance, clinical relevance, and impact. Recent tracer development is mentioned, ...

In Vivo Breast Cancer Measurement with a Handheld Laser Breast Scanner

HBS is a handheld system for noninvasive breast cancer detection based on frequency domain photon migration. It performs broadband modulation on near-infrared laser intensity and derives the scattering and absorption coefficients from phase and amplitude measurements. Recovered optical properties of phantom and tissue by HBS clearly show the difference between normal and cancer tissue. Measurem...
