3D scanner

An MRI scan is a quick procedure that uses a magnetic field and pulses of radio wave energy to produce a static image of the brain. It provides a very detailed diagnostic 3D picture, distinguishing the different type of soft tissue and structures within the brain for the researchers. This provides excellent spatial resolution, unlike the PET scan discussed earlier. Additionally, there is no known long term side effects…

awake at 7am, relying on recently chugged black coffee to instill in me some sense of alertness. My short frame, donning a scrub, fell next to much taller Dr. Fritz, a thoracic surgeon at Gwinnett Medical Center. Once Dr. Fritz’s I.D. met the door scanner, a bustling energy swirled around me. Nurses spoke to one another succinctly. Doctors reviewed patient records and xrays. And I-- I followed Dr. Fritz’s long strides into an operating theater where bright overhead lights beamed into the…

Although this increases the amount of space in the scanner, this causes a weaker magnetic field so it could miss some abnormalities in the tissues or organs. There is also a branch of MRI, known as functional MRI, that has been developed to create brain maps of the nerve cells. They have developed a silent MRI scanner since the typical MRI creates a large volume of sound. The noise is removed by using a type of 3D technology technique called Silenz. When it is used with the corresponding…

Figure 11: MRI-LINAC at Sunnybrook Canada (Ref 12) Photo of the project during setup and installation (Ref 15) First patient (Utrecht): The first clinical application was very simple case which is the palliative treatment of spinal bone metastases. This allowed to test the geometrical accuracy of the system on real patients. The vertebra is easily visualized on the integrated megavoltage imaging system and allows for accurate comparison of field co-ordinates with MRI co-ordinates.…

Bowel cancer is the term used for a cancerous tumour that presents itself in the large bowel and can go by other names such as colon or rectal cancer depending on where it starts from, it also includes rectal cancer. It can also present itself in the small intestine. Around 1 in 20 people residing in the United Kingdom will develop a form of bowel cancer and about 40,000 cases of bowel cancer are diagnosed each year. There are four sections to the bowel in which cancer can develop in any of them…

a clear plastic panel that appears to be blue not just to protect the eyes but also to be used as a screen that can be projected on. It also has a custom built operating system of its own. It supports: ● all day battery life ● HD video recording ● 3d mapping ● 4 cameras (two in the back and two in the…

Types of Psychology. Cognitive Psychology Cognitive Psychology is a fairy modern approach to human behaviour that is the scientific study of the mind as an information processor. Cognitive psychology is mainly that if we want to know what makes people tick then we need to understand the internal processes of their mind. It involves the study of the human mental processes and how they play a role in how we feel, how we think and the way we behave. This type of psychology focuses on how humans…

Garbage is spread everywhere, lives are lost, buildings are razed to the ground, and cars have been tossed like soccer balls. Actually, this would be the effects of a natural disaster.Earthquakes are among the dreadful consequences of nature that may cause loss of life and food shortage (Figure 1).In fact, earthquakes often happen when two rock plates encounter each other, creating friction. Due to the strength of the force, shock waves will be sent through the ground, creating an earthquake (…

do not even exist. An example of a dot that is not always looked at as positive is the idea of 3D printers. Not only do these printers use up a lot of energy, they pose a health risk when used at home by burning unhealthy air emissions (Gilpin, 2014). There are also companies that are trying to sell guns that were made with a 3D printer. These guns cannot be detected by metal protectors or x-ray scanners; guns that cannot be detected are banned under Congress’ Undetectable Firearms Act. This is…
