Using Apple Vision Pro during surgery 16.03.2024

The medical team at Cromwell Hospital in London used Apple Vision Pro for the first time during two spinal surgeries. This event confirms the headset's potential as a medical tool that will change the way surgical practice is performed. Although the doctors themselves did not use Vision Pro, the operating room nurse worked with virtual reality using glasses while preparing and performing procedures. The headset made it possible to view virtual screens in the operating room, select instruments and monitor the progress of the operation. Software developed by eXeX, a company that specializes in creating artificial intelligence-based applications for surgery, has significantly improved the patient care process. Using Apple Vision Pro opens up new opportunities for developing healthcare applications such as clinical education, surgical planning, training and medical imaging. Implementation of Apple Vision Pro in the medical industry ... >>

Carbon storage in the North Sea 16.03.2024

Norwegian Energy Minister Terje Åsland has announced the launch of the Longship project, which aims to create a central carbon dioxide storage facility in the North Sea. This ambitious project is valued at $2,6 billion and aims to apply CCS (carbon capture and storage) technology to mitigate the impact of climate change. Norway already has experience in CCS, thanks to the successful Sleipner and Snohvit projects, and is now looking to increase the amount of carbon sealed beneath the seabed. Longship's plan calls for capacity to capture and store 1,5 million tons of carbon annually over 25 years. Despite the positive outlook, there are concerns about the long-term consequences of such storage. However, proponents of the project argue that offshore carbon storage has a number of advantages, including minimal environmental impact. The Longship project is carried out with the participation of Equinor, Shell and TotalEnergies through the joint venture Northern Li ... >>

Mini-organs grown from human amniotic fluid 15.03.2024

An international team of scientists led by Professor Fan Xiulin from Zhejiang University has developed a unique method of growing mini-organs from cells found in human amniotic fluid. This significant medical breakthrough could lead to improved diagnosis and treatment of congenital diseases. The organoids, which are three-dimensional cellular structures that mimic organs on a smaller scale, were grown from lung, kidney and small intestine cells found in amniotic fluid. This method opens up new possibilities for studying various fetal conditions and may be the key to early diagnosis and treatment of birth defects. Although no treatment has yet been attempted, the scientists hope their research will help combat the serious congenital diseases that affect millions of newborns each year. This breakthrough could change medical interventions by making it possible to diagnose and treat congenital diseases. ... >>

50-megapixel Samsung ISOCELL GN1 sensor 24.05.2020

The family of Samsung ISOCELL photosensors for smartphone cameras has been replenished with another novelty - a model called ISOCELL GN1 with an optical format of 1/1,31". , which supports both Dual Pixel and Tetracell technologies.

With a relatively larger sensor cell size, the Samsung ISOCELL GN1 is said to take mobile cameras to the next level, combining higher light sensitivity for low-light shots with fast DSLR-level autofocus for action scenes.

1,2 µm is the cell size used in traditional smartphone camera sensors, while over the past year the market has seen a clear trend towards a rapid increase in resolution and a reduction in the physical size of individual cells.

Samsung ISOCELL GN1 appears to be a direct competitor to the new Sony IMX689 sensor (Oppo Find X2 Pro), which is characterized by a resolution of 48 megapixels and a cell size of 1,22 microns. By default, the Samsung sensor will capture 12,5 megapixel photos by combining the signal of four neighboring pixels (Tetracell technology).

Dual Pixel is another prominent feature of the new sensor. The latest flagship Galaxy S20 Ultra with a 108MP camera without Dual Pixel is known to have had focusing problems - after complaints from journalists and users, the company released several firmware updates to improve camera performance. According to Samsung, the new ISOCELL GN1 sensor has the fastest phase detection autofocus system on the market.

Dual Pixel technology places two photodiodes next to each other in a single pixel that can receive light from different angles to determine the phase. Thanks to this, the sensor is able to instantly detect and focus on the desired stationary or moving object from any angle, even in low light conditions. Samsung also provides a software algorithm that receives light information from each photodiode to produce high-resolution images comparable to 100MP.

Samsung ISOCELL GN1 also supports Smart-ISO technology to automatically select the "correct" ISO value depending on the environment, electronic stabilization and supports video recording up to 8K at 30 frames per second.
