83. Transvenous pacemaker placement: left lateral decubitus position and wireless digital radiography. (PubMed)

Transvenous pacemaker placement: left lateral decubitus position and wireless digital radiography. A patient presented with symptomatic third degree atrioventricular block requiring emergency transvenous pacemaker placement. During the procedure, wireless digital radiographs tracked the position of the pacemaker electrode, which repeatedly missed the target right ventricle. The patient was then rolled to left lateral decubitus position and the electrode was advanced into the right ventricle (...) , achieving electrical capture, hemodynamic stability, and symptom resolution. We review the published literature on transvenous pacemaker placement and identify two innovations: left lateral decubitus position to facilitate catheter placement and wireless digital radiography for procedure guidance.Copyright © 2017 Elsevier Inc.

My initial reactions were similar to several of those who were interviewed for the article. The digital pill, which provides electronic information to confirm whether someone has ingested the medication, has great potential to become a tool of coercion (...) . Aripiprazole (Abilify) is classified as an antipsychotic medication, which is often prescribed to people who have beliefs that machines and other surveillance tools are in their bodies. Why would the nascent technology of a digital pill make its debut for this population? I have several other concerns about this digital pill: 1. The purported mechanism of action for aripiprazole (Abilify) involves hand-waving, which is yet another reason why its debut as a digital pill is perplexing. To the manufacturer’s

86. Enhancement of digital radiography image quality using a convolutional neural network (PubMed)

Enhancement of digital radiography image quality using a convolutional neural network Digital radiography system is widely used for noninvasive security check and medical imaging examination. However, the system has a limitation of lower image quality in spatial resolution and signal to noise ratio. In this study, we explored whether the image quality acquired by the digital radiography system can be improved with a modified convolutional neural network to generate high-resolution images (...) with reduced noise from the original low-quality images. The experiment evaluated on a test dataset, which contains 5 X-ray images, showed that the proposed method outperformed the traditional methods (i.e., bicubic interpolation and 3D block-matching approach) as measured by peak signal to noise ratio (PSNR) about 1.3 dB while kept highly efficient processing time within one second. Experimental results demonstrated that a residual to residual (RTR) convolutional neural network remarkably improved

89. Seeing elements by visible-light digital camera (PubMed)

Seeing elements by visible-light digital camera A visible-light digital camera is used for taking ordinary photos, but with new operational procedures it can measure the photon energy in the X-ray wavelength region and therefore see chemical elements. This report describes how one can observe X-rays by means of such an ordinary camera - The front cover of the camera is replaced by an opaque X-ray window to block visible light and to allow X-rays to pass; the camera takes many snap shots (called (...) single-photon-counting mode) to record every photon event individually; an integrated-filtering method is newly proposed to correctly retrieve the energy of photons from raw camera images. Finally, the retrieved X-ray energy-dispersive spectra show fine energy resolution and great accuracy in energy calibration, and therefore the visible-light digital camera can be applied to routine X-ray fluorescence measurement to analyze the element composition in unknown samples. In addition, the visible-light

93. Experimental measurement-device-independent quantum digital signatures (PubMed)

Experimental measurement-device-independent quantum digital signatures The development of quantum networks will be paramount towards practical and secure telecommunications. These networks will need to sign and distribute information between many parties with information-theoretic security, requiring both quantum digital signatures (QDS) and quantum key distribution (QKD). Here, we introduce and experimentally realise a quantum network architecture, where the nodes are fully connected using (...) a minimum amount of physical links. The central node of the network can act either as a totally untrusted relay, connecting the end users via the recently introduced measurement-device-independent (MDI)-QKD, or as a trusted recipient directly communicating with the end users via QKD. Using this network, we perform a proof-of-principle demonstration of QDS mediated by MDI-QKD. For that, we devised an efficient protocol to distil multiple signatures from the same block of data, thus reducing

97. Compression in Digital Imaging

Recommendation T.81 respectively. JPEG is the most commonly used method for compression of digital images. DICOM Version 3.0 supports the use of JPEG Image Compression through the Encapsulated Format. JPEG reduces the size of an image by breaking it into 8x8 blocks and within each block, shifting and simplifying the colors so there is less information to encode. As pixels are changed only in relation to the other pixels within their block, two identical pixels that are next to each other, but in different (...) blocks, could be transformed in different ways. When high compression ratios are used, the block boundaries become obvious, causing the 'blockiness' or 'blocking artifacts’ frequently observed in common JPEG. B. DICOM JPEG 2000 JPEG-2000 is a new image coding system that uses state-of-the-art compression techniques based on wavelet technology. The JPEG-2000 standard was adopted by ISO as ISO/IEC 15444-1 (JPEG 2000), for digital compression and coding of continuous-tone still images. JPEG-2000

Tumescent technique in digits: a subcutaneous single-injection digital block. A modified subcutaneous single-injection approach to achieve digital block using a tumescent technique is described.A convenient sample of patients requiring digital anesthesia for minor surgical procedures on the fingers or thumb in the emergency and plastic departments were enrolled into the study. Digital nerve block was performed by injecting 1% lidocaine into the volar subcutaneous space at the proximal digit (...) to create a firm, turgid feel to the tissue, the so-called tumescent state. The volume of anesthetic was based on the size of the digit. All nerve blocks were performed by 1 surgeon. Successful digital anesthesia was defined as complete loss of pinprick sensation on both the dorsal and volar aspects of the digit and the ability to complete the anticipated minor surgical procedure without pain. All patients were followed for 1 month to assess for adverse events.Between August 2009 and January 2011, 123
