Photoacoustics And Molecular Imaging In Cancer Evaluation

May 16th, 2011 No comments

Imagine a world in which the diagnosis of cancer did not involve a surgical biopsy. With photoacoustics and molecular imaging, that world may soon become a reality. Both technologies have great implications for the diagnosis and evaluation of cancer.

Over one hundred years ago, photoacoustics were discovered by Alexander Graham Bell. He found that a rotating disk made sounds when bombarded with photons. The sound could be detected with a stethoscope. When the disk absorbed the heat energy from the photons, it released sound waves that matched the frequency of its rotation.

In a modern photoacoustic system, pulsed light is sent through a biological medium. The light is absorbed and deflected within the space. The spatial distribution creates sound sources that are transformed into images. Images are produced by acoustic sensors. The system can image molecular properties at high resolution in vivo, or within the body.

The amount of light absorbed depends on the type of tissue. When blood is scanned, oxygenated and deoxygenated blood have different appearances. This allows the device to pick out detailed features, like arteries and veins, without injecting dyes into a patient’s bloodstream. It produces detail comparable to a CT scan or an MRI. However, molecular imaging is much cheaper. It can be done with a handheld device instead of a machine that costs millions of dollars.

Images can also be gathered by binding gold nanoparticles to specific biomarkers. For instance, nanoparticles can be combined with a specific kinase and then introduced through the imaging system. Other occurrences of the kinase in the cells would show dramatically in the photoacoustic image. The presence of certain kinases and proteases help scientists identify certain biological processes. These processes determine tumor behavior. They also determine how well tumors respond to treatment.

Molecular imaging can determine several factors in cancer metastasis. First, it can determine prognosis. Certain biomarkers indicate the aggressiveness of angiogenesis and metastasis. The level of aggressiveness determines how intense the treatment needs to be. Second, it can make predictions. It can do this by detecting the presence or absence of therapeutic targets. These targets then determine the type of chemotherapy oncologists will prescribe.

Third, imagine allows doctors to measure therapeutic response. They can know instantly how well a cancer therapy is working. Finally, it helps scientists to increase their understanding of the biology of cancer. They can learn why some patients respond to treatments while others do not.

Photoacoustic molecular imaging can guide biopsy needles deep into tissue. It can also measure oxygen levels in both vascular and lymph nodes, which indicates whether or not a tumor is malignant. It could be a precursor to photothermal cancer therapy. Radiant energy would be converted to a thermal energy that could destroy cancer cells. Detailed images would make the treatment highly localized and decrease harm to normal tissues.

Photoacoustics and molecular imaging can help us understand cancer like never before. It can also help to improve quality of life and patient outcomes. In time, it may replace expensive CT scans and MRIs. It may even replace invasive surgical biopsies.

Word processor is also the program used by the majority. Your work is usually supported by anyone Else’s computer that you might need to send it to. The program is a big step up if you are currently using a program like notepad to do your writing.

Power Point is very common when it comes to creating presentations. This program allows you to set up a presentation easily and hassle free. Before Power Point came to be most people had to set up presentations manually with poster board. Most companies that frequently have presentations will more than likely use the Power Point software. Schools also use this program to created classroom projects. People seem to like this product because they can make information presentable in a much easier and quicker way.

The companies operating systems can also be very user friendly. They are the most common operating systems being used today and this makes communication between people easier. If you are sending or receiving information from another person, especially if it is through a home PC, chances are is their operating system is a version of Microsoft.

They also offer automatic updates for most of the products that they make. This will let them update your system for you when it is necessary. This is much better than having to find and set up an update by your self. Some companies will actually charge you money for program extensions that should have come with the original version.

All and all there are many special features from Microsoft computer software and the products that they create. Most people use their products over others. This basically makes communication easier as other computers will more than likely be run by a Microsoft product.

December 8th, 2010 No comments

The use of geographical data is becoming a significant part of our daily lives. The internet has become an important technological mechanism for GIS location-based activities. As a result, the internet has become the preferred means of real-time delivery of geographical information.

Today, internet users are able to download internet-based innovative spatial data in the form of digital map layers consisting of geographic information system (GIS) features resulting in easy to understand digital mapping. Access to networked spatial data has resulted in the use of location-based services for a variety of purposes. It is now common to find a broad range of downloadable map-based applications and data sets online. Innovative spatial data for navigation and internet location-based applications can now be used by anyone needing real-time delivery of geographical information.

The use of web mapping has evolved to the point where users can access an internet platform to find out exactly where they are, how to get a particular location, and to help them find the best route to the location. The most common interface for spatial searching via the web is a map. For instance, a map-based search engine uses a specific interface that can support a broad range of spatial searches. As well, users now have mobile mapping platforms that provide exact locations, routing instructions, and details about the specific location being queried.

Everyday, millions of people are now using spatial data to find location-based solutions and help them make better decisions. Innovative spatial data is now being offered in a variety of different packages to assist with decision-making in both the business and public sector. Delivering spatial data online involves three specific areas that include: the spatial data, the information technology, and the method of data delivery. Spatial data is used in a variety of forms that includes: mapping services which gives users the ability to manipulate the maps online, route information to give the user specific directions, efficient geocoding which involves the generation of a coordinate, and web services which involves providing access to data that can be distributed across multiple channels so that other applications can use this data for their own specific purposes.

Today, we are now seeing incredibly powerful geospatial tools online which have improved spatial data collaboration, increased speed and power, provided effective online analysis, and provided more data in an easy to understand output to improve a user’s understanding of the data. With the advances of wireless connectivity, position sensing, and mobile devices, the market for location-based services is rapidly increasing. For instance, wireless emergency services with wireless capabilities that allows the pinpointing of a cell phone is in great demand as an essential service. As well, businesses can provide the exact directions to their location.

The internet has had a remarkable effect on the way businesses and individuals communicate. More information is now available that makes it easier to harness the power of location-based applications and list cleaning. Innovative spatial data for navigation and internet location-based applications has become a vital part of implementing effective location intelligence solutions.
