Hitachi wins FDA nod for proton beam therapy real time image gating system

Hitachi (NYSE:HIT) said this week it won FDA 510(k) clearance for its Real Time Image Gating System designed for use with its proton beam therapy systems. Real Time Image Gating Proton Beam Therapy is designed to track and irradiate tumors in motion, using a 2mm diameter gold marker close to the tumor to establish its location as a reference via computed tomography. A dual-axis, orthogonal X-ray system is then used with pattern recognition software to identify the spatial location of the marker, and irradiation during treatment is performed only when the gold marker moves to within millimeters of the planned irradiation location. Development of the technology was sponsored in part by a grant from the Funding Program for World-Leading Innovative R&D on Science and Technology in 2010, sponsored by the Japanese Government. The grant was awarded to a joint project between Hitachi and Hokkaido University. Hitachi won clearance for the RGPT technology from Japan’s Pharmaceuticals Medical Device Administration in 2014. “Hokkaido University has been developing motion tracking technology in the field of X-ray therapy. By combining this technology with Spot Scanning technology, the accurate irradiation of tumors, including those attached to large organs in motion which are difficult to irradiate with X-rays, will be possible and will lead to greater adaptation. I am very pleased that this innovation for highly precise irradiation will become broadly available around the wor...

By SAURABH JHA Of my time arguing with doctors, 30 % is spent convincing British doctors that their American counterparts aren’t idiots, 30 % convincing American doctors that British doctors aren’t idiots, and 40 % convincing both that I’m not an idiot. A British doctor once earnestly asked whether American physicians carry credit card reading machines inside their white coats. Myths about the NHS can be equally comical. British doctors don’t prostate every morning in deference to the NHS, like the citizens of Oceania sang to Big Brother in Orwell’s dystopia. Nor, in their daily rounds, do the...

Authors: Wu J, Dai F, Hu G, Mou X Abstract Excessive radiation exposure in computed tomography (CT) scans increases the chance of developing cancer and has become a major clinical concern. Recently, statistical iterative reconstruction (SIR) with l0-norm dictionary learning regularization has been developed to reconstruct CT images from the low dose and few-view dataset in order to reduce radiation dose. Nonetheless, the sparse regularization term adopted in this approach is l0-norm, which cannot guarantee the global convergence of the proposed algorithm. To address this problem, in this study we introduced the l1-...

AbstractPurposeTo investigate if bone substitutes are strictly necessary to restore the vertebral body height and improve the clinical outcome, in patients with thoracolumbar or lumbar AO type A post-traumatic vertebral fractures, managed with balloon kyphoplasty combined with posterior screw and rod system.Methods105 patients with post-traumatic thoracolumbar spine fracture were recruited. At baseline, the patients underwent a CT and an MRI of the spine. Clinical evaluation was performed, using the Visual Analog Scale (VAS) and the Oswestry Disability Index (ODI), at baseline, 48  h after surgery, at 3-month follow-u...

ConclusionThis study showed an overall 16.3% radiological PCE and 1.4% symptomatic PCE incidence when CAFPS were used due to severe osteoporosis. The symptomatic PCE risk was significant when CAFPS were  >  7 levels; >  14 fenestrated screws; and >  20–25 cc cement volume is used and this may cause PAP increase and right ventricular dilatation.Graphical Abstract

Abstract The University of Washington (UW) Clinical Neutron Therapy System (CNTS), which generates high linear energy transfer (LET) fast neutrons through interactions of 50.5 MeV protons incident on a Be target, has depth-dose characteristics similar to 6 MV x-rays. In contrast to the fixed beam angles and primitive blocking used in early clinical trials of neutron therapy, the CNTS has a gantry with a full 360<sup>○</sup> of rotation, internal wedges, and a multi-leaf collimator (MLC). Since October of 1984, over 3,178 patients have received conformal neutron therapy treatments using the UW CNTS. I...

Note by Dr Sumer Sethi Recently we launched our unique medical education centric app for young Doctors calledeMedicoz. On this in addition to routine discussions Doctors also discuss various aspects of the profession. In a recent discussion series young Doctors brainstormed and tried crystal balling the future of the medicine and technology. It is wonderful to hear their thoughts on future. It is for certain future looks really happening for medical profession, computers and machine learning will re- invent the way we practice medicine. Targeted therapy is another important area, 3D printing , understanding the value ...

Discussion Our hypothesis was not confirmed. The clinical outcomes after more than 1 year of follow-up are disappointing, as was the large number of nonunion cases and the lack of tantalum integration. These technical failures can be explained by insufficient construct stability and/or insufficient implant porosity. Level of Evidence IV (retrospective cohort study).
