Performance Evaluation of a Position-Sensitive SiPM-based Gamma Camera for Intraoperative Imaging
Aramis Raiola, Fabio Acerbi, Cyril Alispach +4
The POSiCS camera is a handheld, small field-of-view gamma camera developed for multipurpose use in radio-guided surgery (RGS), with sentinel lymph node biopsy (SLNB) as its benchm…
A novel shape-based loss function for machine learning-based seminal organ segmentation in medical imaging
Reza Karimzadeh, Emad Fatemizadeh, Hossein Arabi
Automated medical image segmentation is an essential task to aid/speed up diagnosis and treatment procedures in clinical practices. Deep convolutional neural networks have exhibite…
Quantitative and Qualitative Performance Evaluation of Commercial Metal Artifact Reduction Methods: Dosimetric Effects on the Treatment Planning
Mohammad Ghorbanzadeh, Seyed Abolfazl Hosseini, Bijan Vosoughi Vahdat +3
The presence of metal implants within CT imaging causes severe attenuation of the X-ray beam. Due to the incomplete information recorded by CT detectors, artifacts in the form of s…
Comparison of different deep learning architectures for synthetic CT generation from MR images
Abbas Bahrami, Alireza Karimian, Hossein Arabi
MRI-guided radiation treatment planning is widely applied because of its superior soft-tissue contrast and no ionization radiation compared to CT-based planning. In this regard, sy…
Deep learning-based noise reduction in low dose SPECT Myocardial Perfusion Imaging: Quantitative assessment and clinical performance
Narges Aghakhan Olia, Alireza Kamali-Asl1, Sanaz Hariri Tabrizi +4
Clinical SPECT-MPI images of 345 patients acquired from a dedicated cardiac SPECT in list-mode format were retrospectively employed to predict normal-dose images from low-dose data…
Quantitative investigation of low-dose PET imaging and post-reconstruction smoothing
Behnoush Sanaei, Reza Faghihi, Hossein Arabi
In this study, 18F-FDG PET/CT brain scans of 50 patients with head and neck malignant lesions were employed to systematically assess the relationship between the amount of injected…
