A left intraventricular lipoma resected with the assistance of endoscopic camera

Asian Cardiovascular and Thoracic Annals, 2023
Cardiac lipomas are extremely rare benign neoplasms of the heart. Most of them do not cause clinical symptoms, so far they are found incidentally in the majority of cases. Here, we describe a case of left intraventricular lipoma in an asymptomatic 34-year-old man which found by transthoracic echocardiography at comprehensive medical examination ...

A novel technique proposition for determining the resection margins in lung resection by using a thermal camera

General Thoracic and Cardiovascular Surgery, 2023
Determination of resection margins is very important in anatomical lung resections for both oncologic outcomes and postoperative complications. Absence of intersegmental plans naturally in segmentectomy surgeries and presence of incomplete fissure variationally in pulmonary lobectomy procedures constitute a challenge for surgeons in determining ...

Role of a portable gamma-camera with optical view for margins assessment of pulmonary nodules resected by radioguided surgery

European Journal of Nuclear Medicine and Molecular Imaging, 2021
Radioguided occult lesion localization (ROLL) of pulmonary nodules is an alternative to hook-wire. Both required of a histological margin assessment. The activity emerging from the radiotracer allows to obtain an intraoperative scintigraphic image of the surgical specimen by a portable gamma-camera (PGC) fitted with an optical view, which provides ...

Robust 6DOF measurement for non-overlapping multi-camera systems based on uncertainty-weighted space resection

2019 International Conference on Optical Instruments and Technology: Optoelectronic Measurement Technology and Systems, 2020
This paper introduces an improved 6DOF measurement method for the non-overlapping multi-camera systems. In contrast to the existing equal-weighted bundle adjustment methods, the proposed method assigns an uncertainty based weight to each of the non-overlapping cameras.

Multi-image space resection based geometric calibration for Four bands CCD camera

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
High altitude photographic work such as Aerial photogrammetry and UAV photography has very high demands on geometric optical parameters of the CCD camera, one millimeter or one pixel error of geometric optical parameters tends to cause a few meters or even dozens of meters error on the ground, so the camera's high-precision geometric optical parameters

The Tumor Resection Camera (TReCam), a multipixel imaging probe for radio-guided surgery

2009 IEEE Nuclear Science Symposium Conference Record (NSS/MIC), 2009
Using the POCI camera, we recently demonstrated the clinical impact of per-operative imaging techniques thanks to a successful clinical trial. Taking advantage of both the POCI experience and the availability of new pixelated detectors, we are developing a new hand held gamma camera TReCam (Tumor Resection Camera).

Self-normalising linear camera resection

2015 International Conference on Image and Vision Computing New Zealand (IVCNZ), 2015
An alternative linear method of estimating camera parameters from an image of a known object is presented. It has the immediate advantages over the commonly recommended direct linear transform that it does not require prior normalisation of the data and gives an unbiased estimate of the focal length even for noisy data.

Is the Use of a Robotic Camera Holder Economically Viable? A Cost Comparison of Surgical Assistant Versus the Use of a Robotic Camera Holder in Laparoscopic Liver Resections

Surgical Laparoscopy, Endoscopy & Percutaneous Techniques, 2017
The laparoscopic approach has gained acceptance in the field of hepatopancreaticobiliary surgery. It offers several advantages including reduced blood loss, reduced postoperative pain, and shorter length of stay. However, long operating times can be associated with surgeon and assistant fatigue and image tremor.

Intraoperative application of thermal camera for the assessment of during surgical resection or biopsy of human’s brain tumors

SPIE Proceedings, 2014
Motivation to undertake research on brain surface temperature in clinical practice is based on a strong conviction that the enormous progress in thermal imaging techniques and camera design has a great application potential. Intraoperative imaging of pathological changes and functionally important areas of the brain is not yet fully resolved in ...
