background chronic obstructive pulmonary disease (copd) is a devastating disease.while there is no cure for copd and the lung damage associated with this disease cannot be reversed, it is still very important to diagnose it as early as possible. objectives in this paper, we propose a novel method based on the measurement of air trapping in the lungs from ct images to detect copd and to evaluate...

conclusions gated spect mpi has a good correlation with echocardiography for the measurement of left ventricular ef, edv, and esv in patients with severe heart failure. however, the absolute values of these functional parameters from echocardiography and gated spect mpi measured with different software packages should not be used interchangeably. results a good correlation was found between ech...

A 79-year old male with lung nodules on chest computed tomography underwent video-assisted thoracoscopic-surgical middle lobe wedge resection, with pathology proven adenosquamous carcinoma. Repeat video-assisted thoracoscopic-surgical-biopsy was performed for recurrent disease. Subsequent staging computed tomography revealed herniation of the gallbladder through the abdominal wall (Figs 1 and 2...

Complete and precise characterization of a quantum dynamical process can be achieved via the method of quantum process tomography. Using a source of correlated photons, we have implemented several methods, each investigating a wide range of processes, e.g., unitary, decohering, and polarizing. One of these methods, ancilla-assisted process tomography (AAPT), makes use of an additional "ancilla ...

We use hyperentangled photons to experimentally implement an entanglement-assisted quantum process tomography technique known as direct characterization of quantum dynamics. Specifically, hyperentanglement-assisted Bell-state analysis enabled us to characterize a variety of single-qubit quantum processes using far fewer experimental configurations than are required by standard quantum process t...

Hand-Assisted Thoracoscopic Surgery for pulmonary metastasectomy through sternocostal triangle access allows manual palpation of both lungs, thus permitting effective treatment of lung metastases. In our research, 62 patients from November 2001 to January 2012 underwent our Hand-Assisted Thoracoscopic Surgery procedures for pulmonary metastasectomy. Clinical data, including the number of pulmon...
