Histochemical Correlates of 15O-Water–Perfusable Tissue Fraction in Experimental Canine Studies of Old Myocardial Infarction
TLDR
The absolute mass and proportion of histochemically defined noninfarcted tissue may be quantitated with PTF and PTI in the area of myocardial infarction segments. Expand
Histochemical correlates of (15)O-water-perfusable tissue fraction in experimental canine studies of old myocardial infarction.
TLDR
The absolute mass and proportion of histochemically defined noninfarcted tissue may be quantitated with PTF and PTI in the area of myocardial infarction segments. Expand
DOI-PET image reconstruction with accurate system modeling that reduces redundancy of the imaging system
TLDR
A compressed imaging system model for DOI-PET image reconstruction, in order to reduce computational cost while keeping image quality, and results show that the proposed method followed by ML-EM reduces computational cost effectively while keeping the advantages of the accurate system modeling and DOI information.

Performance characteristics of a new 3-dimensional continuous-emission and spiral-transmission high-sensitivity and high-resolution PET camera evaluated with the NEMA NU 2-2001 standard.
TLDR
The new integrated SET-3000 G/X PET scanner has good overall performance, including high resolution and sensitivity, and has the potential of reducing whole-body acquisition time to less than 10 min while improving small-lesion detectability with a low radiation dose. Expand
Performance evaluation of a high-sensitivity large-aperture small-animal PET scanner: ClairvivoPET
TLDR
ClairvivoPET is well suited to quantitative imaging even with short scan times, and will provide a number of advantages in new drug development and for kinetic measurement in molecular imaging. Expand
Basic evaluation of a C-shaped breast PET scanner
For diagnosis of very small lesions of breast cancer on very early stage, a dedicated breast positron emission tomography (PET) scanner consisting of four-layer depth of interaction (DOI) detectorsExpand
NEC Density and Liver ROI S/N Ratio for Image Quality Control of Whole-Body FDG-PET Scans: Comparison with Visual Assessment
TLDR
NEC density, representing count statistics per body volume, reflects the visual image quality assessment and may be utilized for quality control of whole-body FDG-PET images together with the liver ROI S/N ratio. Expand
Implementation of noise reduction for PET using hybrid nonlinear wavelet shrinkage method
Positron emission tomography (PET) imaging provides the functional information and precise physiological uptake of radioactivity in a patient's body. But the photon level of PET system has fewerExpand
A four-layer depth of interaction detector block for small animal PET
We are now planning to develop a positron emission tomograph dedicated to small animals such as rats and mice which meets the demand for higher sensitivity. We propose a new depth of interactionExpand
Preliminary resolution performance of the prototype system for a 4-Layer DOI-PET scanner: jPET-D4
We are developing a high-performance brain PET scanner, jPET-D4, which provides 4-layer depth-of-interaction (DOI) information. The scanner is designed to achieve not only high spatial resolution butExpand
