“Firefighters hiked down the hill through waist-deep brush expecting the worst, but found the driver of the truck was still alive but severely injured and ill,” officials said.Ĭowlitz County is in southwest Washington. They also spotted a truck in the ravine that matched the description of the vehicle belonging to the missing man and reported it to rescuers, fire officials said.

No one knew where the man had gone for more than five days until residents spotted tire tracks leading to the ravine. He drove off the road and plunged 150 feet down a steep and “heavily wooded” ravine before landing at the bottom, rescuers said. The 56-year-old man was found alive in his green truck Sunday, May 21, in Cowlitz County, according to Cowlitz 2 Fire & Rescue. The projection-domain primary and auxiliary modulesĪre interconnected for progressive denoising and few-angle reconstruction.Īdaptive Data Consistency (ADC) modules improve prediction accuracy byĮfficiently fusing the outputs of the primary and auxiliary modules.Įxperiments using clinical MPI data show that our proposed method outperformsĮxisting image-, projection-, and dual-domain techniques, producing moreĪccurate projections and reconstructions.Tire tracks led rescuers to a man who had been missing for more than five days at the bottom of a ravine in Washington, fire officials said. The image-domain network provides a prior estimate for the To overcome theseĬhallenges, we propose a dual-domain iterative network for end-to-end jointĭenoising and reconstruction from low-dose and few-angle projections of cardiac Potentially resulting in lower reconstruction accuracy. Projections in fewer angles using fewer detectors to reduce hardware expenses, The patient's radiation exposure, but it will lead to increased image noise.Īdditionally, the latest dedicated cardiac SPECT scanners typically acquire Reducing the dose of the injected tracer is essential for lowering Tomography (SPECT) is widely applied for the diagnosis of cardiovascularĭiseases.
