Development and Initial Demonstration of a Low-Dose Dedicated Fully 3D Breast CT System

A new, clinic-ready, low-dose breast CT system was developed and is undergoing initial clinical validation, which includes a small focal spot pulsed x-ray source and 30x30cm2 flat panel detector that facilitates whole-breast and universal anterior chest-wall imaging.

Initial Development of a Dual-Modality SPECT-CT System for Dedicated Mammotomography

Results on a combined SPECT-CT system show that emission projection images are contaminated by X-ray scatter photons resulting in the reconstructed emission images having a higher signal level and emission contamination also increases noise in the transmission image resulting in reducing the SNR in reconstructed CT images.

X-ray Cone-Beam Breast Computed Tomography:

We present the design and preliminary imaging evaluation of a bench-top apparatus for X-ray cone-beam breast computed tomography (CBBCT), assembled for technical evalua- tion and for laboratory tests…

Evaluation of fully 3-D emission mammotomography with a compact cadmium zinc telluride detector

Results indicate that 3-D mammotomography, incorporating a compact CZT detector, is a promising, dedicated breast imaging technique for visualization of tumors <1 cm in diameter.

Patient Bed Design for an Integrated SPECT-CT Dedicated Mammotomography System

The need for novel camera trajectories to satisfy both chest wall proximity imaging and patient comfort is indicated, and the effects of breast volume imaged within the common FOV and table angles, which are assumed to correspond to patient comfort, are examined.

A novel method to characterize the MTF in 3D for computed mammotomography

Findings indicate that the phantom can be used to assess the intrinsic image resolution in 3D as well as potential degradative effects of measurements in various media.

Basic Study on the Development of a High-Resolution Breast CT

Results indicate that the prototype of high-resolution breast CT system developed overcomes the limitations of both the mammogram and existing breast CT systems.

Investigating novel patient bed designs for use in a hybrid dual modality dedicated 3D breast imaging system

An optimal patient bed design for a completely under-bed hybrid imaging system was determined, allowing the CT projection beam to nearly entirely image the chest wall, however at the cost of reduced angular sampling for CT.

Design, Implementation, and Characterization of a Dedicated Breast Computed Mammotomography System for Enhanced Lesion Imaging

The outcome of this project is a fully functioning 3D dedicated breast imaging system ready for initial patient studies and indicates the potential for sub dual-view dose uncompressed breast imaging.

Implementation and CT sampling characterization of a third-generation SPECT–CT system for dedicated breast imaging

Initial imaging results demonstrate that additional off-axis projection views of various geometric resolution phantoms facilitate more complete sampling, more consistent attenuation value recovery, and markedly improved reconstructions in this single hybrid SPECT–CT system.

Initial study of quasi-monochromatic X-ray beam performance for X-ray computed mammotomography

Simulation results showed that tube potentials of 50-70 kVp with filters of Z=57-63 yielded quasimonochromatic x-ray spectra with improved FOMs, and initial experimental measurements corroborate simulation results in that, relative trends and rank order of contrast ratios and exposure efficiency were in agreement.

Simulations demonstrate that this quasi-monochromatic x-ray technique may enhance tissue separation for a newly developed cone beam computed mammotomography application for an uncompressed breast.

Optimizing beam quality for x-ray computed mammotomography

While uncompressed breast thickness affected absolute values of the measurement criteria, they had little effect on beam hardening and contrast ratio and did not alter the optimal operating range, indicating that these highly attenuating filters can provide superior performance for mammotomography.

The preliminary simulation results support the proposed cone-beam volume CT mammographic imaging modality in respect to feasibility and practicability for mammography and will potentially provide significantly better low contrast detectability of breast tumors and more accurate location of breast lesions.
