Area of Science:
- Medical Imaging
- Nuclear Medicine
- Radiological Physics
Background:
- Previous research focused on quantitative brain SPECT.
- Breast imaging requires specialized techniques for accurate volumetric analysis.
Purpose of the Study:
- To adapt quantitative SPECT technology for breast imaging (SPECT mammotomography).
- To develop a cost-effective system for high-resolution breast imaging.
- To improve image reconstruction speed and quality in SPECT mammotomography.
Main Methods:
- Designed a dedicated SPECT mammotomography system with short focal-length fan-beam collimation.
- Modeled and treated Poisson noise in sinogram space.
- Implemented compensation for Compton scattering, uniform attenuation, and collimator response.
Main Results:

01:21Tandem Mass Spectrometry
Tandem mass spectrometry is a technique that uses multiple mass analyzers in series to obtain a higher selectivity and reduce chemical noise during analyte detection. Instruments with multiple analyzers separated by an interaction cell enable secondary fragmentation and selected study of the fragment ions.Secondary fragmentations occur in the interaction cell and can be induced by various factors. Fragmentation induced by collision with inert gases, such as N2, Ar, He, etc., is called...
01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
