Q. What do I need to capture an image?

To capture a image of an x-ray, we recommend using either a digital camera, or x-ray scanner. For ultrasound (or other video), the Python by Videonics is an excellent device. It can take still images and create MPEG movies that can be sent via VSN to specialists. For internal imagery, the MedRX unit connected to the Python is a very good combination.

For cytology, there are a number of options. You can use a digital camera, such as the Kodak DC260, the MedRX unit, or a digital microscope camera such the MicroImage camera or the Sony DXC-151A. Pros and cons of each camera are discussed below.

For dermatology cases, a digital camera is an excellent choice.

Q. What kind of digital cameras are recommended?

We have reviewed available cameras and can recommend either the Kodak DC260 / DC280 / DC290, AGFA 1680, or the Nikon CoolPix 950. The Kodak camera is capable of capturing x-ray images, cytology, dermatology, opthalmology, and text. The AGFA camera excels at x-ray capture but falls short for cytology. The cost for the Kodak cameras are around $700. The cost for the AGFA camera is about $900. The Kodak and AGFA camera can usually be obtained locally.

These digital cameras have pixels counts of 1.6 to 2.2 Million pixels, which approach the pixels/inch count of low end x-ray scanners costing many thousands of dollars more (about 95-110 vs. about 140).

WARNING!!! We have tested several hand-held digital cameras and reviewed many more. The only cameras we are currently recommending are listed above. Other brands often do not have sufficiently high pixel counts to provide a diagnostic quality image. Some brands, such as the Olympus, have the quality but have difficult operating characteristics. We review new cameras as they are released and will be happy to provide a verbal review of any camera should you wish to call us.

Q. What kind of high-end video cameras are recommended?

We have tested cameras that utilize the hyper-HAD CCD chip technology and found them to be quite capable for internal and cytology work. Examples of such cameras are the MicroImage camera (about $3000) and the Sony DXC-151A (about $1500). In general, video cameras are poor choices for x-ray capture due to the inherent low resolution of any video signal.

Q. Are there additional costs associated with the cameras?

Yes. If you wish to capture microscope-based images using a video camera, an appropriate c-mount adapter is required. C-mount adapters typically cost between $150 and $300.

Q. Can I capture movement?

Yes. Movement such as such as an ultrasound of a beating heart, pyloric valve movement, bronchoscopy, or an animal walking can easily be captured and sent to a specialist. Using the Python, you can make a movie using any video input. A 30 second movie takes about 1.5 Mbytes of storage. A short, 5-8 second movie can take as little as 300 Kbytes of storage. Often a short movie can provide information that can not be given any other way.

Q. What is the best way to capture cytology?

The easiest way is to use a permanently mounted digital video camera mounted on a triocular microscope. The cheapest, and probably best, way is to use a digital camera, such as the Kodak DC260. The Kodak DC260 will provide a much higher quality image than even the best video camera system.

Q. How else can I use VSN?

You can use VSN as a communication tool to your clients. Instead of sending your images to a specialist, you can send them to yourself, and call your Internet connected client and allow them to view the images while you discuss the case with them. This often allows you to obtain more rapid approval for proposed procedures and certainly provides your clients with a feeling that your clinic is using the latest in technology in the care of their pet. We are also working on a "release instruction" option that will enable you to provide descriptions and notations for the client to read at checkout time and at home.

Q. What are the costs for consultations?

Prices range from $22.95 for higher volume use to $42.95 for occasional use. Mixed modality cases (e.g. radiology and cytology) will be charged for each discipline involved. There is also a $3 transmission charge for each case sent. All costs are in US dollars.

Q. Who are the VSN specialists?

VSN's specialists currently include Dr. Larry Tilley (Cardiac and Abcominal Internal Medicine), Dr. Marc Papageorges (Radiology and Ultrasound), Dr. Michele Menard (Cytopathology), Dr. Steve Roberts (Opthalmology), Dr. Robert Payne (Orthopeadic Surgery), Dr. Juan Marti (Small Animal Surgery; VSN USA and VSN Europe), Dr. Ben Colmery (Dentistry), and Dr. Jon Shiroma (Radiology). Should you desire that another specialist be added to VSN, call us and we will contact that specialist and get them set up to receive your cases.

Q. How much does the VSN software cost?

We provide the VSN software free of charge. There is a $3 (U.S.) charge for each case transmitted. We will be happy to assist you in installing the software. If you would like more detailed assistance, there is a support program available for $250 per year.

Q. How do I get the VSN software?

On the VSN website (www.veterinary.com), there is a link that will allow you to register and download the software. Click on the link and follow the instructions.

Q. What kind of computer, etc., will I need?

VSN requires a Windows ‘95 (or later) based computer and recommends a processor speed of at least 200 MHz. Also, at least 2 GB of available disk space is recommended. You will also need an Internet connection.
