Real-time Virtual Intraoperative CT for Image Guided Surgery [PDF]
arXiv, 2021 Abstract. Purpose: This paper presents a scheme for generating virtual intraoperative CT scans in order to improve surgical completeness in Endoscopic Sinus Surgeries (ESS). Approach: The work presents three methods, the tip motion-based, the tip trajectory-based, and the instrument based, along with non-parametric smoothing and Gaussian Process ...

Self-explaining Hierarchical Model for Intraoperative Time Series [PDF]
arXiv, 2022 Major postoperative complications are devastating to surgical patients. Some of these complications are potentially preventable via early predictions based on intraoperative data. However, intraoperative data comprise long and fine-grained multivariate time series, prohibiting the effective learning of accurate models.

Autonomous Tissue Scanning under Free-Form Motion for Intraoperative Tissue Characterisation [PDF]
, 2020 In Minimally Invasive Surgery (MIS), tissue scanning with imaging probes is required for subsurface visualisation to characterise the state of the tissue. However, scanning of large tissue surfaces in the presence of deformation is a challenging task for the surgeon.

Transesophageal Echocardiographic Approach to a Patient with Suspected Pulmonary Hypertension in the Intraoperative Period [PDF]
Journal of Perioperative Echocardiography, 2017 ABSTRACTPulmonary hypertension (PH) defined by a mean pulmonary artery pressure (MPAP) >25 mm Hg at rest is confirmed by right heart catheterization (RHC). With the rapid development of surgical methods and cardiopulmonary bypass strategies, many children and adults are undergoing surgical correction for their cardiac pathologies.

Beneficial effect of fluid warming in elderly patients with bladder cancer undergoing Da Vinci robotic-assisted laparoscopic radical cystectomy [PDF]
Clinics, 2020 OBJECTIVES: The enhanced recovery after surgery (ERAS) protocol recommends prevention of intraoperative hypothermia. However, the beneficial effect of maintaining normothermia after radical cystectomy has not been evaluated.

Machine stability and dosimetry for ultra‐high dose rate FLASH radiotherapy human clinical protocol
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background The FLASH effect, induced by ultra‐high dose rate (UHDR) irradiations, offers the potential to spare normal tissue while effectively treating tumors. It is important to achieve precise and accurate dose delivery and to establish reliable detector systems, particularly for clinical trials needed to help the clinical transfer of FLASH‐

Abnormal Synchronization Between Cortical Delta Power and Ripples in Hippocampal Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Discriminating between epileptogenic and physiological ripples in the hippocampus is important for identifying epileptogenic (EP) zones; however, distinguishing these ripples on the basis of their waveforms is difficult. We hypothesized that the nocturnal synchronization of hippocampal ripples and cortical delta power could be used ...

Histopathology for Mohs Micrographic Surgery with Photoacoustic Remote Sensing Microscopy [PDF]
arXiv, 2020 Mohs micrographic surgery (MMS) is a precise oncological technique where layers of tissue are resected and examined with intraoperative histopathology to minimize the removal of normal tissue while completely excising the cancer. To achieve intraoperative pathology, the tissue is frozen, sectioned and stained over a 20- to 60-minute period, then ...
