Subscribing to Vesalius

The information provided on Vesalius is designed to support, not replace, the relationship that exists between a patient/site visitor and his/her physician.

Subscribers can customize Vesalius for their own use, by creating Notes, Personal Thumbnails, Presentations, Quizzes, and Mark-Ups, and accessing them through their Personal Pages. And subscribers can download Vesalius images for non-commercial, short-term educational applications, subject to the Vesalius terms of use.

Subscribers must login in order to access their Personal Pages.

If you have a current e-mail address ending in ".mil", you qualify for a free Vesalius subscription. To receive a subscription token, please send e-mail to:

Make sure you specify your name and your ".mil" e-mail address in the message.

Vesalius subscriptions are sold as a package of "sessions". A session is launched each time you login to Vesalius, and expires after you are inactive for 20 minutes – i.e. after you have clicked no links or buttons for 20 minutes. When your session is about to expire due to inactivity, a pop-up window will appear to warn you, and give you a chance to extend your session.

We base subscriptions on sessions, rather than strictly on a term of months, to encourage subscribers to purchase and use their own Vesalius subscriptions, rather than share one subscription among multiple users. We discourage account-sharing because the Personal Pages features on Vesalius are designed to let individuals customize the site for their own use. These features are undermined when users share a Vesalius account and can (wittingly or unwittingly) alter or undo each other's work. An account shared by multiple users can also be hijacked by anyone willing to change its password.

Vesalius offers three different subscription options, each of which consists of a package of sessions:

20 sessions, to be used within 30 days

$10.00 US

200 sessions, to be used within one year

$20.00 US

1,000 sessions with no expiration date

$50.00 US

Your subscription will terminate when all of your sessions have been used, or when the specified number of days has elapsed (if applicable), whichever comes first. You can renew your subscription either before or after it expires, thereby preserving your Vesalius User ID and your Personal Pages. If you are provided with a subscription "token" by a Vesalius sponsor or an institution, you can use the token either to create a new subscription or to add sessions and days to an existing subscription.

Subscriptions must be prepaid and are non-refundable. You can choose one of two ways to complete your subscription:

A. Use a prepaid subscription token.
Your subscription may have been paid for in advance, in which case you can complete your subscription by using a "token" (example: bongo-12345) provided for you by the purchaser. Or you can purchase a token yourself, by paying for your subscription in advance using a bank check. No personal checks will be accepted.

To pay by bank check, the check should be payable to "Vesalius Studios" in the amount of $10.00, $20.00 or $50.00 US. It is essential that you write your e-mail address on your bank check. Send the check to:

Lion Reef Software
5630 8th Road North
Arlington, VA 22205
United States

After we receive your payment, we will use your e-mail address to send you a token that you can use to complete the subscription process. If you already have a Vesalius subscription, you can use a token to extend or renew your subscription term.

After you have received your subscription token, please have your token ready, then proceed to Step 1 on this page to complete the subscription process.

B. Pay for your subscription with a credit card.
To complete your subscription now using a credit card, please have your VISA, MasterCard, or American Express card ready, then proceed to Step 1 below.

Step 1
The first step in subscribing is choosing a unique Vesalius User ID. Your Vesalius User ID must be from 6-12 characters in length, and can contain letters from A-Z or a-z or numbers from 0-9, with no blank spaces (e.g. jsmith4, alan1978, tunafish...)

Please Select and Enter a Vesalius User ID, then click the "Check User ID" button to check whether this ID is available for use.

(Note: pick a User ID – do not enter your subscription token here!)
