[Hu Chen et., al] Low-Dose CT With a Residual Encoder-Decoder Convolutional Neural Network (RED-CNN)1 文章核心思想低剂量CT重建问题是近年以来在生物医学图像领域有一定研究价值的topic,传统算法包括频率…
Even with a low dose technique, this contributes substantially to the total effective dose. Using low or ultra-low dose CT techniques ameliorates this but may introduce substantial artifacts, particularly those due to photon starvation in bone-rich cross-sections. The objective of th...

Preventative Diagnostic Center in Las Vegas provides patients the access to low-dose non-invasive CT scans.
一、Ultra-low Dose PET2022介绍 正电子发射断层扫描 (PET) 是肿瘤学、神经病学和心脏病学临床常规程序中的主要成像方式之一。PET广泛应用的关键瓶颈之一是电离辐射剂量。随着长轴视场 (FOV) 全身 PET 的出现,它可以实现以前无法实现的图像质量和量化水...
This study develops an improved Feldkamp–Davis–Kress (FDK) reconstruction algorithm using non-local total variation (NLTV) denoising and a cubic B-spline interpolation-based backprojector to enhance the image quality of low-dose cone-beam computed tomography (CBCT). The NLTV objective function is...
dose is a key parameter to understanding real-world effects. Although acute effects are more likely to be observed following high-dose exposures, recording the consequences of low-dose levels over a lifetime is necessary to understand possible risks of CNPs. Thus, cells were exposed to CNPs at...

“Thus, if there is a clinical benefit to proton radiography and proton CT, the studies can be repeated as often as necessary to maximize such benefit – without the fear that such benefits will be negated by any detrimental effects from radiation dose,” he explains. Consistency check A pro...
