To evaluate the accuracy of monitoring intrafraction motion during stereotactic radiotherapy with the optical surface monitoring system. Prior studies showing a false increase in the magnitude of translational offsets at non-coplanar couch positions prompted the vendor to implement software changes. This study evaluated two software improvements intended to address false offsets.

We have developed a safe, non-contact, intra-operative guidance system to optimize tumor resection in neurosurgery. The Modulated Imaging (MI) is non-contact optical imaging technology dev...
Pectus excavatum (PE) and carinatum (PC) are the most common anterior chest wall deformities. These disorders often come to light for the first-time during childhood and can cause signific...
Optical guidance for percutaneous tracheotomy in intensive care is usually performed by bronchoscopy. Recently, an endotracheal tube with a camera mounted at its tip (VivaSight-SL) has bee...
The mechanism by which a neuronal process outgrows toward a target led by the GROWTH CONE. Local guidance cues are provided by cell surface proteins that act on the growing axon.
The use of light interaction (scattering, absorption, and fluorescence) with biological tissue to obtain morphologically based information. It includes measuring inherent tissue optical properties such as scattering, absorption, and autofluorescence; or optical properties of exogenous targeted fluorescent molecular probes such as those used in optical MOLECULAR IMAGING, or nontargeted optical CONTRAST AGENTS.
The continuous measurement of physiological processes, blood pressure, heart rate, renal output, reflexes, respiration, etc., in a patient or experimental animal; includes pharmacologic monitoring, the measurement of administered drugs or their metabolites in the blood, tissues, or urine.
Dimeric cell surface receptor involved in angiogenesis (NEOVASCULARIZATION, PHYSIOLOGICAL) and axonal guidance. Neuropilin-1 is a 140-kDa transmembrane protein that binds CLASS 3 SEMAPHORINS, and several other growth factors. Neuropilin-1 forms complexes with plexins or VEGF RECEPTORS, and binding affinity and specificity are determined by the composition of the neuropilin dimer and the identity of other receptors complexed with it. Neuropilin-1 is expressed in distinct patterns during neural development, complementary to those described for NEUROPILIN-2.
Moving a patient into a specific position or POSTURE to facilitate examination, surgery, or for therapeutic purposes.
