Medical radiation exposure to patients has increased with the development of diagnostic X-ray devices and multi-channel computed tomography (CT). Despite the fact that the low-dose CT technique can significantly reduce medical radiation exposure to p

Radiopharmaceutical agents for positron emission tomography (PET), such as -FDG and , have been used not only for whole-body PET imaging but also for intraoperative radionuclide-guided surgery due to their quantitative and sensitive imaging character

Single photon emission computed tomography (SPECT) has been widely used for preclinical research. High resolution small animal SPECT imaging can be achieved by employing a pinhole or multi-pinhole collimators. However, the useful FOV is narrow compar

An optical/nuclear hybrid surgical technique using ICG-99mTc-nanocolloid can improve lesion detectability by detecting both fluorescence and gamma signals. However, a hybrid multimodal laparoscope that can obtain both NIR and gamma images is not avai

We have investigated a dual-ended readout detector based on two silicon photo-multipliers (SiPMs) using a 30 mm long cerium-doped lutetium-yttrium oxyorthosilicate ( ${\rm Lu}_{0.5}{{\rm Y}_{1.4}}{\rm Si}_{0.5}:{\rm Ce}$ , LYSO) crystal to study the

A small-animal single photon emission computed tomography (SPECT) system having compact size and low cost was designed using monolithic LGSO scintillation crystals and micro parallel-hole collimators through Monte Carlo simulations. A spatial resolut

Positron emission tomography (PET) with high resolution and high sensitivity is desirable for detecting cancers and neurological diseases. In this work, a depth-of-interaction (DOI)-time-of-flight (TOF) PET has been attempted to achieve both high spa

Purpose The aim of this study is to integrate NIR, gamma, and visible imaging tools into a single endoscopic system to overcome the limitation of NIR by using gamma imaging and to demonstrate the feasibility of endoscopic NIR/gamma/visible fusion ima

For positron emission tomography (PET) inserts to magnetic resonance imaging (MRI) applications, optical fibers have been used for some time to transfer scintillation photons to photomultiplier tubes positioned outside the fringe magnetic field. We p
