Recovery of total I-131 activity within focal volumes using SPECT and 3D OSEM.
We experimentally investigated the SPECT recovery of I-131 activity in multiple spheres located simultaneously at different locations within a cylindrical phantom that had an elliptical cross section. The sphere volumes ranged from 209 cc down to 4.2 cc. A Prism 3000 camera and two types of parallel-hexagonal-hole collimation were employed: high energy (HE) and ultra high energy (UHE). Using ap...
متن کاملIterative 3D bayesian restoration method of SPECT volumes (OSEM-R) - Application in striatal imaging
SPECT imaging suffers from low spatial resolution and statistical noise. Consequently, the contrast of small structures is reduced, visual detection of defects is limited and exact quantification is difficult. To improve the contrast, it is possible to incorporate a blurring model into the iterative reconstruction process such as OSEM3D. This approach is well known to be effective, but time con...
متن کامل3D-OSEM and FP-CIT SPECT quantification: benefit for studies with a high radius of rotation?
OBJECTIVES Dopamine transporter imaging with single-photon emission computed tomography (SPECT) is a valuable tool for both clinical routine and research studies. Recently, it was found that the image quality could be improved by introduction of the three-dimensional ordered subset expectation maximization (3D-OSEM) reconstruction algorithm, which provides resolution recovery. The aim of this s...
متن کاملImpact of a commercial 3D OSEM reconstruction algorithm on the 177Lu activity quantification of SPECT/ CT imaging in a Molecular Radiotherapy trial
The purpose of this study was to investigate the influence of the Ordered Subsets Expectation Maximization (OSEM) reconstruction updates implemented in the 177Lu SPECT/CT imaging processing in molecular radiotherapy. A NEMA IEC Body PhantomTM was used to quantify activity in refillable spheres of five different sizes. Images were obtained with a hybrid dual-head SPECT-CT imaging system (Symbia ...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
