Brain surgeries are very complex: they need to be extremely accurate, since you want to spare healthy tissue; planning is very thorough, as the surgeon looks in multi-imaging modalities – for instance, where the tumor is located, what needs to be removed, and what is the best path; execution of the plan needs to be …
Our team has followed with deep attention the recent Hamlyn Symposium. In particular, we have enjoyed the great presentation by Professor Laura Marcu from UC Davis about fluorescence imaging during surgery, using that modality as a surgical aid. Fluorescence imaging is very widely used in microscopy: you inject a specific dye into the specimen, and …
RSIP Vision’s oncology software combines detection of lesions and tumors in the human body with tracking those findings along CT scans performed during the research: in particular lung, lymph nodes and liver. These tools enable a quick and accurate assessment of the efficacy of the new treatment.
The golden standard for measuring tumors is the RECIST score. RSIP Vision developed an automated module to accurately measure the RECIST score from CT scans as well as the exact 3D volume of the tumors. Changes in volume are a reliable measure of the progression or remission of the tumor, enabling to evaluate the responsiveness of the treatment in a relatively short time.
The typical catheter navigation system relies on fluoroscopy, which exposes patients to dangerous irradiation. To limit the dose throughout the operation, endoscopic cameras are used to guide catheter near the target site of the procedure. When vessel diameter becomes too small to insert an endoscopic camera, magnetic resonance imaging (MRI), CT or ultrasound scans are …
Magnetic resonance imaging is a ubiquitous clinical imaging modality, in which patients are placed in a device inducing a magnetic field, and the relaxation of exited hydrogen atoms are collected to form an image of an organ or their entire body. The size of MRI machines makes them practically immobile, whereas the insight gained from …
Registration is a phase of orthopedic surgeries in which a visualization system is called to support the surgeon. This system provides real time view of the surgery environment and the information from the CT imaging. Two different steps of registration are executed here: tracking system registration and C-Arm X-ray to CT registration. Registration between tracking …
During the last few decades, the field of biomedical imaging was shaken by major breakthroughs, which have completely changed the way physicians can observe imaging data. For instance, not long time ago, radiologists received images (taken by CT, MRI or X-Ray) and had to analyze them from scratch. In the case of a full body MRI, they had to …
Dermascopy is one of the main modalities used to detect skin abnormalities and lesions such as malignant melanoma. It is estimated that in the United States alone there are every year 70,000 newly diagnosed malignant skin lesions, resulting in 9,000 deaths. Early detection of malignant lesions can save many lives owing to the simple surgery …
