... verification performed with electronic portal imaging devices (EPIDs) and two-dimensional images. Megavoltage cone beam CT (MV CBCT) generates an accurate three-dimensional representation of the patient anatomy, moments before the same X-ray beam is used for treatment. The three-dimensional images will provide...

... (unpublished data of the authors); careful intraoperative fusion positioning (unpublished data of the authors) is crucial for patient satisfaction. We strongly encourage using cup- and cone-reamers for dome-shaped joint preparation as it allows for accurate positioning without excessive loss of metatarsal...

... Abstract Flat-panel cone beam CT is maturing to a stable imaging modality. Applications are being developed for radiotherapy, volumetric diagnostic scanning, rotational angiography and mobile C-arm technologies with soft tissue imaging capabilities. Volumetric image-guided radiotherapy...

... of dental caries lesions, oral hygiene, and pain guides the care plan. Depending on the severity of MIH and associated symptoms, intraoral radiographs and cone beam computed tomography may be necessary. In cases of scheduled extractions, extraoral radiographs, photographs, and study models are indicated...

..., including toxic retinopathy in response to chloroquine and hydroxychloroquine exposure [ 7 ]. In retinal degenerations, automated perimetry can be used to assess macular sensitivity where macular dystrophy (e.g. Stargardt disease, pattern dystrophies) or cone-rod degeneration is suspected. Automated...

... of wild-type cells to replace degenerating cells and to rescue gene function, sequential gene and cell therapy, and in vivo reprogramming of rods to cones. These approaches highlight cutting-edge advances in cell and gene therapy, and cellular lineage conversion in order to devise new therapies...

..., and cone dystrophy); autosomal dominant (cone dystrophy, adult vitelliform dystrophy, pattern dystrophy, North Carolina macular dystrophy, Doyne honeycomb dystrophy, Sorsby macular dystrophy, and some cases of Stargardt-like macular dystrophy); X-linked (X-linked retinoschisis, XLRS), and mitochondrial...

... terminal for neurotransmission to the second-order cells of the retina. The photoreceptor layer is composed of two specific types of photosensitive cells, rods and cones. The rod cells comprise approximately 97% of the retinal photoreceptors, and the cone cells comprise the remaining 3% of the retinal...

... of the intersection of the ionizing radiation beams that create the radiobiological effect. Non-invasive immobilization systems first proposed for linear accelerator or proton radiation technologies have now been developed for the Leksell Gamma Knife ICON radiosurgical system. The ICON technology adds a cone-beam...

... Abstract The ICON® Gamma Knife treatment unit is a modification of the Perfexion unit with the addition of a frameless-based treatment option and stereotactic cone-beam computed tomography (CBCT). The addition of infrared markers for the detection of patient motion and the use of a stereotactic...

... Abstract Multidetector computed tomography has been the benchmark for visualizing bony changes of the ear, but has recently been challenged by cone-beam computed tomography. In both methods, all inner ear bony structures can be visualized satisfactorily with 2D or 3D imaging. Both methods...
