Exclusive: A Closer Look at the Magnifi iPhone Optical Adapter

Magnifi iPhone adapter Exclusive: A Closer Look at the Magnifi iPhone Optical Adapter

Last month, Medgadget announced the development of the Magnifi iPhone adapter from start-up Arcturus Labs (Palo Alto, CA), which connects your iPhone 4 or 4S to optical instruments ranging from microscopes to binoculars and telescopes.

To learn more about the evolution of the Magnifi, we spoke with newlyweds Xianne and Isaac Penny who came up with the rough idea for the device while in grad school at Stanford University. They began the development of the product after graduating. Isaac Penny also worked as an engineer at Intuitive Surgical (Sunnyvale, CA), where he helped create the daVinci Single-Site line of instruments.

“Somewhat related to what I was doing for research at Stanford, I was working on medical devices for the developing world,” Isaac Penny says. In the course of that research, he visited a number of clinics in Africa. “A lot of them don’t even have PCs or laptops but they have their cellphones and they were documenting stuff with cell phones, which they would attach to a camera,” he remembers. “Grad students at Stanford do that a lot, too. So we figured maybe other people who use microscopes do as well.”

While the idea was first developed for microscopes, they realized that it would work with other optical instruments such as binoculars and telescopes as well. “Feedback from customers and users that has helped us home in on the product,” Isaac Penny explains.

“There were some unexpected fields where we didn’t see that this would apply to,” Xianne Penny says.  For instance, it can be used by optometrists and ophthalmologists because it would fit their slit-lamp microscope. It can also be used by endodontists—dental surgeons who do root canals and use microscopes to look inside the drill hole in teeth to observe what the root looks like from the inside of the tooth.

The device also helps in teaching situations that involve microscopes. With the Magnifi, multiple students can gather around the microscope and view a slide at the same time—instead of taking turns to do so. It also can be used with services such as Skype or Facetime to project images to a projector computer. “You could have a live demo for education in a classroom,” Isaac Penny says.

The functionality of the Magnifi can be further expanded with third-party apps. For instance, apps such as Camera Plus and Camera Awesome enable users to lock the focal length to prevent the potentially annoying autofocus issues. Another app known as Eye Microscope can be used to add scale bars, date and magnification to images taken with the phone.

The device works on eye pieces in the range of 1 to 1.5 inches in diameter. It must also be able to slide over the eyepiece at least 1 inch without obstruction, so that the camera’s optics can get close enough to align.

Arcturus Labs is planning on coming out with another adapter to enable Magnifi to be used for an even wider range of optical instruments, namely spotting scopes and other optics with large diameter eyepieces. The new adapter will be interchangeable with current Magnifi case and future cases within the product line.

New Microscope Enables Needle Free Blood Testing

New Microscope Enables Needle Free Blood Testing

For most people blood tests are synonymous with needle-sticks. However, researchers from the biomedical engineering department at the Israel Institute of Technology (Technion) may have found a way to take the pain out of some of our blood tests in the future. The researchers have developed a new microscope that can non-invasively image individual blood cells.

The microscope uses spectrally encoded confocal microscopy (SECM), a technique which allows for 2D spatial imaging of the blood cells. In order to image the moving blood cells, a probe is pressed against the skin which generates a line spectrum of light from red to violet. As blood cells near the surface of the skin cross the projected spectrum they scatter the light, which is collected by the probe and analyzed to generate 2D images of the blood cells.

F Cubed’s Pathogen Detector Will Make Swimming Holes Safer This Summer

F Cubed's Pathogen Detector Will Make Swimming Holes Safer This Summer

During our recent tour of Northeast Indiana, we had the opportunity to visit F Cubed (F3), a startup supported by the Innovation Park at Notre Dame. F3 is developing a portable device that allows for rapid detection of DNA of harmful pathogens in under 30 minutes.

We’ve written about a number of similar lab-on-chip detectors, but what sets the F3 system apart is its biochip technology. F3′s biochip, which is smaller than the size of a thumbnail, allows for the detection of multiple pathogens without the use of expensive and complicated optical devices. According to F3,

An Update on Altapure’s Ultrasonic Clinical Environment Sterilization System

An Update on Altapure's Ultrasonic Clinical Environment Sterilization System

Back in February, we wrote about Altapure‘s adaptation of military sonar technology to sterilize clinical environments. During our recent trip to northeast Indiana, we had the opportunity to visit Altapure’s home on the campus of the University of Notre Dame.

Since our last mention, Altapure has been able to not only get their product on the market, but is already working on a newer version of the device that clocks in at 1/3 the size of the current model but has the same power.

A Jet Tour of Northeast Indiana’s Medical Device Hub

A Jet Tour of Northeast Indiana's Medical Device Hub

This past week, Medgadget was invited to take a tour of Northeast Indiana, a region of ten counties surrounding and encompassing the city of Fort Wayne. You might already know about Warsaw, about 30 miles from Fort Wayne, as the headquarters for DePuy, Biomet, Zimmer, and a number of other companies that make the city the leading orthopedic device leader in the world. However, the rest of Northeast Indiana has also been evolving into a thriving medical device manufacturing hub, as labor is available, land is plentiful, and the region is very open and friendly toward the medical device manufacturing industry. In fact, according to the Northeast Indiana Regional Partnership, our host for the two day tour, the region has consistently been a leader in terms of dollars invested and jobs created in the industry. Over two days, we toured a number of different companies and talked to a number of executives about what makes their businesses successful and why they’re at a good place being in Northeast Indiana.

Our first stop was Micropulse, a contract manufacturer of implants and instruments for a number of large medical device clients. Micropulse was originally founded to produce parts for the automotive industry, but in the early 2000′s, founder and CEO Brian Emerick saw his business growing stagnant, and so he switched to medical devices and has never looked back since. What’s interesting about Micropulse is that its facilities are also headquarters to the OrthoVation Center, a new incubator for Emerick’s other medical product ventures. The OrthoVation Center currently is home to four companies: Del Palma Orthopedics, Nanovis, BioSpine, and Sites Medical.

Crowdsourced Pathology, Thanks to Video Gamers

Crowdsourced Pathology, Thanks to Video Gamers

Researchers from UCLA’s School of Engineering and Applied Science and the School of Medicine have designed a system that can harness distant groups of people to analyze pathology images for signs of disease. They tested the ability of non-professionals to quickly learn to detect malaria when looking at images of red blood cells and have shown that if necessary, with a bit of help from online crowds, large groups of people can potentially be screened for the disease.

The system they built relies on video gaming to attract people to do the visual tasks necessary to spot malaria.  The study subjects, mostly untrained newbie undergrads, showed a spotting ability that was within 1.25 percent of medical professionals.

Electron Microscopy in Stunning, Real-Time 3D – Coming Soon to a Laboratory Near You!

Electron Microscopy in Stunning, Real-Time 3D - Coming Soon to a Laboratory Near You!

Over at the Japan Science and Technology Agency (JST), researchers have developed a special scanning electron microscope (SEM) capable of generating high-resolution 3D images of the study subject. 3D SEM is actually not new technology, however, the JST SEM is the first device of its kind that can show 3D images in real-time. The secret is a special electromagnetic lens that slants an electron beam aimed at a specimen, which results in instant left and right parallax images needed to create a 3D effect. Normal 3D SEM imaging techniques require the left and right parallax images to be taken separately and at different angles.

If you have a pair of red/blue 3D glasses, be sure to take a look at the above anaglyph of a piece of metal, produced by the JST SEM.

High Speed Deformability Cytometer Feels Through Thousands of Cells a Second

High Speed Deformability Cytometer Feels Through Thousands of Cells a Second

Malignant cells are different from regular cells in their biochemistry as well as in their morphology. Studying physical properties of such cells can often be more advantageous than looking at their biochemical characteristics because labeling is not required and sample preparation is easier to perform.

Scanning through thousands of cells to spot a cancerous one requires a fast device, and researchers at UCLA have developed one called deformability cytometer that can effectively “feel” around the entire perimeter of individual cells, using a liquid flow trap, at 2,000 cells per second.

The Domino Effect Hits Point of Care Testing

The Domino Effect Hits Point of Care Testing

A team of researchers from the University of Alberta in Canada has developed a new DNA analysis system capable of performing up to 20 simultaneous tests. The system, dubbed the Domino, uses polymerase chain reaction technology to amplify and identify specific DNA sequences.

Like many point of care diagnostic technologies, the Domino consists of a bench top unit and a disposable microfluidic cartridge containing an array of twenty gel posts. Each of the posts acts as a separate interface to a single sample of blood allowing several genetic tests to be performed simultaneously. The Domino may be used to screen for specific diseases or to determine genetic resistance to particular medication.
