Neuromotor development and visual acuity in premature infants submitted to early visuo-motor stimulation [PDF]
, 2008 To investigate the effects of early visual stimulation on the development of tonus and posture control and of grating visual acuity of preterm infants, eight infants received visual stimulation that induced head motion during the first 6 months of life ...

Automated charting of the visual space of insect compound eyes [PDF]
arXiv, 2021 This paper describes the automatic measurement of the spatial organization of the visual axes of insect compound eyes, which consist of several thousands of visual units called ommatidia. Each ommatidium samples the optical information from a small solid angle, with an approximately Gaussian-distributed sensitivity (half-width of the order of one ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose An evaluation of the accuracy, safety, and efficiency of the Halcyon ring delivery system (RDS) for stereotactic radiosurgery (SRS) treatment to relatively small (1–3 cm) brain lesions. Methods After completing the extensive in‐house quality assurance checks including Winston–Lutz test and independent dose verification via MD Anderson ...

A method to determine the impact of visual function on lesion detection performance [PDF]
, 2016 There are few professions in which visual acuity is as important as it is to radiologists. The diagnostic decision making process is composed of a number of events (detection or observation, interpretation and reporting), where the detection phase is ...

Symmetric Models for Visual Force Policy Learning [PDF]
arXiv, 2023 While it is generally acknowledged that force feedback is beneficial to robotic control, applications of policy learning to robotic manipulation typically only leverage visual feedback. Recently, symmetric neural models have been used to significantly improve the sample efficiency and performance of policy learning across a variety of robotic ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Stereotactic radiotherapy (SRT) is a highly effective treatment with precision for small, localized lesions. Proton therapy, characterized by the Bragg peak, offers superior dose conformity compared to photon‐based approaches. However, challenges remain in minimizing lateral penumbra and optimizing dose delivery, particularly for small

The evaluation of vision in children using monocular vision acuity and strereo-acuity tests [PDF]
, 2011 Monocular visual acuity and stereo-acuity tests were carried out on 308 children between the ages of two to twelve years. Children with reduced visual acuity (V.A) and who failed the RandomDot E (RDE) stereo- acuity tests were further examined for ...
