Authorized Medical Physicist (AMP)

April 29, 2009 · Posted in Employment, State / Fed Regs · Comment 

10CFR Part 35 requires that a physicist who needs to do HDR procedure be listed as an Authorized Medical Physicist (AMP) in the material license. The link below discusses the §35.51 Training for an Authorized Medical Physicist.

http://www.nrc.gov/reading-rm/doc-collections/cfr/part035/part035-0051.html

I found this link to be quite useful, and I refer to it many times, so I am putting it here for your reference. This is especially useful for and applicable to new physicists who need to do HDR or for the RSOs who need to amend the material license to include new physicists in the license. I am guessing that all the agreement states have adopted this regulation from the NRC (or something similar to it).

Further, if you are changing your job and are already listed as an AMP in the material license in your present job, it’s important to take a copy of the material license with you to your new job! Believe me, this will save you, the RSO, and the institution a lot of time and possibly spare all of you a headache.

Physics Fees and Medical Physicists’ Salaries

April 28, 2009 · Posted in Employment · Comment 

As physicists, we most likely have at least two things in common: 1. We are extremely busy with technical and scientific issues every day, and 2. Most of us are salaried employees. Putting these two things together, it is probably fair to say that most of us do not have the time to find out how our salaries are determined and where they come from. My personal feeling is that knowing the source of our salaries–which basically boils down to how much our organizations receive for our services–would help us negotiate better when it comes to raises and benefits. If like me, you are a busy, but curious physicist–someone who always wanted to know the formula for CPT but did not have the time to find out–the article in the link below gives you an exact formula for how Medicare pays MDs. This analytical article is very informative, educational, and useful. While the formula in this article applies to physicians–not physicists–it makes sense that a similar document and formula exists for technical and physics charges. If someone knows a similar source for physics charges/fees, please share it with the rest of us.  Here is the link to the article: http://www.acro.org/washington/RVU.pdf

Making the 2009 AAPM Annual Meeting in Anaheim More Economical

April 27, 2009 · Posted in Conferences / Meetings · Comment 

I have always attended either AAPM summer school or the AAPM annual meeting (or both). The AAPM annual meeting and summer school have always been an excellent source of information for professional growth and development, especially in recent years. The program is rich, the speakers are knowledgable, and the exhibitions are informative and helpful. In addition, the meeting has always been a place to meet and unite with older friends and colleagues. Here are some tips to make this year’s trip a little more comfortable and economical. Read more

Prostate Cancer: IMRT or Seed Implant

April 25, 2009 · Posted in Op-Ed · 5 Comments 

I was in the OR last Friday for a prostate implant procedure. We (i.e. the physics group) prepared the seed, did the proper QA, and set them on the table–ready for implant.  Everything was set. After a short while, a nurse brought the patient into the room. He looked somewhat scared and panicked, as many patients do when they are brought into the OR. He was wondering what we were going to do with him.  He probably remembered the pain he went through when his PVA was done with an ultrasound probe while he was awake. Shortly thereafter, the radiation oncologists and urologists, while chatting it up with each other, arrived in the room. The nurse and the doctors helped to place the patient on the table.  The anesthesiologists prepared to put him under for the implant procedure. Read more

Lester Skaggs, Ph.D. (1911-2009)

April 25, 2009 · Posted in Personal News · Comment 

lesterskaggsLast week the medical physics community lost a pioneer.

Lester Skaggs, Ph.D. passed away on April 3, 2009 at the age of 97 of complications from renal failure. In a career that spanned almost 70 years, his contributions were not only numerous but enduring. A leader and innovator in the truest sense of the word, Dr. Skaggs’s work in the field of medical physics over the course of his career is inspiring for young and established medical physicists alike. Our sincerest condolences to his family, friends and colleagues.

From the Chicago Tribune:

Lester Skaggs helped develop the detonation device for the first atomic bombs as a physicist with the Manhattan Project and then turned his attention to pioneering medical applications for radiation.

A professor at the University of Chicago from 1948 to 1997, Dr. Skaggs, 97, died of complications from renal failure Friday, April 3, in Mercy Hospital and Medical Center, U. of C. spokesman John Easton said.

Shortly after joining the U. of C., Dr. Skaggs was put in charge of developing radiation therapy facilities at the Argonne Cancer Research Hospital, the first medical facility to use radiation to treat cancer when it opened in 1953. (The hospital is now part of University of Chicago Medical Center.)

Along with colleague Lawrence Lanzl, Dr. Skaggs built a linear accelerator, called the Lineac, for medical applications. The Lineac took eight years to finish and cost $450,000. Completed in 1959, the machine was used for 34 years to treat patients from all over the country.

The Lineac was an extension of pioneering work in medical radiation Dr. Skaggs and Lanzl did beginning in 1945. With colleagues from the University of Illinois, they used a high-energy radiation betatron to treat a physics graduate student with a brain tumor, said Lanzl’s wife, Elisabeth, a graduate student who participated in the work.

Although the student died, the treatment shrunk his tumor and was documented in articles that advanced the understanding the medical uses of high-energy radiation, Elisabeth Lanzl said.

Dr. Skaggs designed and built an early analog computer to measure radiation dose to various issues in the early 1960s. In the 1970s, he, with colleague Franca Kuchnir, developed a method to produce neutrons for radiation therapy.

After retiring from the U. of C., Dr. Skaggs spent five years working on a neutron-therapy facility at a hospital in Riyadh, Saudi Arabia. 

Raised on a farm in Missouri, Dr. Skaggs rode a horse three miles to his one-room schoolhouse. In high school, he and a friend built a radio, seeding his fascination with technical machinery, said his daughter Margaret Skaggs.

He got a bachelor’s degree in chemistry and a master’s in physics form the University of Missouri, then studied nuclear physics at the University of Chicago, completing his doctorate in 1939.

He worked briefly at Michael Reese Hospital and with the Department of Terrestrial Magnetism at the Carnegie Institution in Washington, then decamped for Los Alamos to take part in the top secret Manhattan Project.

The mission given him and colleagues was to develop a virtually fail-safe fuse for the atomic bomb. The trick was to set off the bomb in a way that allowed the plane that dropped it fly away safely.

The team came up with a detonation device triggered in relation to its distance from the ground. During his tenure at the U. of C. Dr. Skaggs lived in Park Forest.

Dr. Skaggs’ wife, Ruth, died in 2005.

Survivors include a son, John; a daughter, Mary Anderson; a sister, Lillian Foster; and three grandchildren.

Two memorial services will be held on May 16, the first at 10 a.m. in Faith United Protestant Church, 10 Hemlock St., Park Forest, the second at 3 p.m. in Montgomery Place, 5550 South Shore Drive, Chicago.

Radiation Passport: Radiation Exposure iPhone App

April 17, 2009 · Posted in Miscellaneous · 6 Comments 

iphoneTidal Pool, a Canadian software company, has developed and released a radiation exposure app for the Apple iPhone and iPod Touch. The app is being sold online for $2.99 at the Apple App Store. Before you get all excited like I did, you should know that the app was not developed for medical physicists (or physicians), but rather for the everyday individual interested in keeping track of and calculating their cancer risk due to exposure to ionizing radiation (e.g. medical-related imaging) as well as background radiation due to lifestyle and location. In fact, the purpose of the app as stated by the developer is: “…to educate about the radiation and cancer risks associated with medical imaging exams and procedures that physicians want you to undergo.

That said, it would be interesting to know how the app calculates actual radiation exposure to the patient for each imaging test as well as the associated cancer risks. For example, just how much does one’s chance of getting cancer go up by getting a CAT scan? Is this app going to deter patients from getting imaging tests for fear of getting cancer?

While this app raises a lot of questions for me, as a medical physicist, it also highlights the absence of any real iPhone apps out there for the medical physics community.

That said, If a decent app comes out that would be of use in medical physics, I might be inclined to go out and buy an iPhone. Until then, though, I’ll stick with my Blackberry, thank you very much.
