A forum for advances in minimally invasive,

image-guided procedures

About WAIS

More than 54 years ago, a few West Coast Interventional Radiologists held the first annual Western Angio Club; establishing a forum for collaborative discussion about new procedures for image guided therapies.  These visionaries included well-known WAIS members, Charles Dotter, Josef Rosch and Franklin Turner. 

In 1970, the Western Angiography Society was formally incorporated by 37 founding members and 3 officers: Dr. James Lecky, Dr. Alan Davidson, and Dr. Stewart Reuter.  The mission of the Society was to provide a forum to share new ideas and to learn from each other's successes, failures and innovative techniques.  Many of those first pioneers made valuable contributions towards improving patient care through the development of new techniques to treat disease.  Others published research findings or worked with engineers to design new catheters and implantable devices, ultimately creating a new industry where minimally invasive procedures provided alternative treatments to peripheral vascular disease, aneurysms, cancer, stroke and many other vascular and non-vascular conditions. 

Today, the Western Angiographic & Interventional Society is proud to continue the legacy of its founders through an annual forum for advancements in minimally invasive, image-guided procedures.  Attendees benefit from interactive discussion in the M&M Sessions, as well as a broad spectrum of topics from today's thought leaders.  In September 2020, we celebrated 50 years since WAIS was incorporated.  In September 2022, we celebrated 52 years and 50 annual conferences.  


The Western Angiographic & Interventional Society was incorporated in 1970 to maintain the highest standard of patient care, providing quality, timely continuing education programs for member physicians and allied health care professionals.

Conference Objectives

The professional goal of WAIS is achieved through an annual seminar combining scientific presentations (by Society members and invited non-member experts), practical interactive discussion sessions, hands-on workshops and professional networking between members and guests.

Annual lectures include the M&M Case Presentations, Rapid Fire Clinical Rundown and The Charles T. Dotter Memorial Lecture. Each year, the Dr. Charles T. Dotter lecture is given by an invited international expert in the field of Interventional Radiology with special emphasis on visionary topics such as newer modalities, long-term results of various therapies, professional development and quality control and monitoring.
