Frame-Based and Mask-Based Stereotactic Radiosurgery: The Patient Experience, Compared
Stereotactic and Functional Neurosurgery, 2021<b><i>Introduction:</i></b> Noninvasive frameless modalities have become increasingly utilized for stereotactic radiosurgery (SRS) for benign and malignant pathologies. There is minimal comparison in the literature of frame-based (FB) and mask-based (MB) SRS. With the dual capabilities of the Elekta Gamma Knife® Icon™, we sought

Predicting Diverse Future Frames With Local Transformation-Guided Masking
IEEE Transactions on Circuits and Systems for Video Technology, 2019Video prediction is the challenging task of generating the future frames of a video given a sequence of previously observed frames. This task involves the construction of an internal representation that accurately models the frame evolutions, including contents and dynamics.

Brainstem Metastases Treated with Stereotactic Radiosurgery: Masked versus Framed Immobilization
World Neurosurgery, 2023Patients with brainstem metastases (BSMs) have minimal surgical options due to high-risk anatomy. To review our efficacy treating BSM using Gamma Knife stereotactic radiosurgery (SRS), we compared results on the basis of the utilization of mask-fixation (MF) or frame-fixation (FF).Data were retrospectively collected for 32 patients.

Temporal masking effect on dropped frames at video scene cuts
SPIE Proceedings, 2004In video sequences, scene cuts produce a temporal masking effect on several kinds of artifacts. This temporal sensitivity reduction of the human visual system could be present before (backward masking) and after (forward masking) scene cuts. Related studies reported a significant forward masking in the first 30 to 100 ms following a scene change ...

Development of Si frame-mounting x-ray masks
SPIE Proceedings, 1994A new type X-ray mask called Si frame-mounting X-ray mask, by using the bonded SOI (Silicon-On-Insulator) technique has been successfully developed. The combination of bonding a flat 2000 micrometers -thickness Si mask-substrate and a 6 mm-thickness Si plate with 0.5 micrometers -thickness SiO2 film, achieved the local flatness less than 0.3 ...

Frame-less and mask-less cranial stereotactic radiosurgery: a feasibility study
Physics in Medicine and Biology, 2010Currently, high-precision delivery in stereotactic radiosurgery (SRS) is achieved via high-precision target localization and rigid patient immobilization. Rigid patient immobilization can result in, however, patient discomfort, which is exacerbated by the long duration of SRS treatments and may induce patient movement.

Parameterizations of Masks for Tight Affine Frames with Two Symmetric/Antisymmetric Generators
Advances in Computational Mathematics, 2003Parameterizations of masks are important for the design of filters with desired properties. By constructing paraunitary matrices, one can obtain tight affine frames. In this paper, the author discusses parameterizations of paraunitary matrices which generate tight frames with two symmetric/antisymmetric generators (framelets).
