Quantum technologies require robust and photostable single photon emitters (SPEs). Hexagonal boron nitride (hBN) has recently emerged as a promising candidate to host bright and optically stable SPEs operating at room temperature. However, the emission wavelength of the fluorescent defects in hBN has, to date, been shown to be uncontrolled, with a wide spread of zero phonon line (ZPL) energies spanning a broad spectral range (hundreds of nanometers), which hinders the potential development of hBN-based devices and applications...

We propose a hybrid laser system consisting of a semiconductor external cavity laser associated to an intra-cavity diamond etalon doped with nitrogen-vacancy color centers. We consider laser emission tuned to the infrared absorption line that is enhanced under the magnetic field dependent nitrogen-vacancy electron spin resonance and show that this architecture leads to a compact solid-state magnetometer that can be operated at room-temperature. The sensitivity to the magnetic field limited by the photonshot-noise of the output laser beam is estimated to be less than 1 pT/Hz...

BACKGROUND: The number of endovascular treatment procedures performed for cerebral aneurysms has markedly increased. However, little is known about the annual effective radiation dose to medical staff in neurointervention fields. We performed a retrospective observational study to investigate the real-time radiation dose to surgeons, nurses, anesthesiologists, and radiologic technologists during endovascular treatment for intracranial aneurysms. METHODS: We measured real-time radiation doses for 2 weeks under standard and reinforced protection, during which 28 procedures were performed, including 23 coil embolizations for unruptured intracranial aneurysms...

Careful protocol selection is required during intraoperative three-dimensional (3D) imaging for spine surgery to manage patient radiation dose and achieve clinical image quality. Radiation dose and image quality of a Medtronic O-arm commonly used during spine surgery, and a Philips hybrid operating room equipped with XperCT C-arm 3D cone-beam CT (hCBCT) are compared. The mobile O-arm (mCBCT) offers three different radiation dose settings (low, standard, and high), for four different patient sizes (small, medium, large, and extra large)...

We investigate the feasibility of using indocyanine green (ICG) fluorescence imaging with interventional radiology (IVR) techniques for indication of liver segments during laparoscopic anatomical liver resection (LapAR). Ten patients with planned LapAR (segmentectomy V, VI, VII, or VIII) were enrolled. Both IVR and LapAR were performed in a hybrid operating room. Two dyes (indigo carmine and ICG) and embolic solutions were injected into the target liver segment. We compared imaging results during LapAR. ICG fluorescence imaging (ICGFI) provided clear visual contrast...

The increasing need for pulmonary resection by video-assisted thoracoscopic surgery (VATS) has presented a greater opportunity to detect small-sized pulmonary nodules by computed tomography (CT). In cases where it is difficult to identify tumor localization intraoperatively, it is necessary to place the VATS marker near the pulmonary nodules before surgery. Conventional percutaneous or bronchoscopic VATS marker placement under local anesthesia is accompanied by patient pain. We clinically applied a new technique to place VATS markers using a bronchoscope under general anesthesia in a hybrid operating room...

BACKGROUND: Nowadays, transvenous lead extraction (TLE) is considered an essential technique in lead management strategy. Since 2011, a multidisciplinary approach was undertaken in our centre involving electrophysiologists, cardiac surgeons and anaesthesiologists to improve cross- unit cooperation and minimize complications and mortality. The present paper reports procedural outcomes and complications of our lead extraction experience. METHODS: We retrospectively collected and analysed data from all consecutive patients undergoing cardiac implantable electronic device leads TLE at the IRCCS Centro Cardiologico Monzino between January 2011 and November 2017...

Small pulmonary lesions can be difficult to localize during video-assisted thoracoscopic surgery. Electromagnetic navigation bronchoscopy (ENB) dye marking of the lesion, particularly when guided by cone beam computed tomography in the hybrid operating room (HOR), is an emerging approach. However, issues with confirmation of dye injection and intraoperative visualization of the colored dye can be unpredictable and challenging. To address these uncertainties, we present our technique of ENB dye marking localization of lung nodule using the triple-contrast dye method in the HOR...

Benign portal vein stenosis is a rare complication following pancreaticoduodenectomy. Because a direct surgical approach to the portal vein is difficult due to severe adhesions following pancreaticoduodenectomy, portal vein stent placement is considered a good treatment option. Herein, we report 3 cases of severe portal vein stenosis following pancreaticoduodenectomy that were treated with portal venous stent placement in a hybrid operating room, combining a conventional operating room with an angiography suite...

We propose germanium-vacancy complexes (GeVn ) as a viable ingredient to exploit single-atom quantum effects in silicon devices at room temperature. Our predictions, motivated by the high controllability of the location of the defect via accurate single-atom implantation techniques, are based on ab-initio Density Functional Theory calculations within a parameterfree screened-dependent hybrid functional scheme, suitable to provide reliable bandstructure energies and defect-state wavefunctions. The resulting defect-related excited states, at variance with those arising from conventional dopants such as phosphorous, turn out to be deep enough to ensure device operation up to room temperature and exhibit a far more localized wavefunction...

The unique and outstanding electrical and optical properties of graphene make it a potential material to be used in the construction of high-performance photosensors. However, the fabrication process of a graphene photosensor is usually complicated and the size of the device also is restricted to micrometer scale. In this work, we report large-area photosensors based on reduced graphene oxide (rGO) implemented with Ag nanoparticles (AgNPs) via a simple and cost-effective method. To further optimize the performance of photosensors, the absorbance and distribution of the electrical field intensity of graphene with AgNPs was simulated using the finite-difference time-domain (FDTD) method through use of the surface plasmon resonance effect...
