Eye-cancer patients to benefit from LBL technician's ingenuity

By Jeffery Kahn

Thanks in large part to the initiative and creativity of mechanical technician Mario Cepeda, a project to transfer LBL's eye cancer treatment program from the Bevatron to UC Davis is proceeding on schedule.

Although the closure of LBL's Bevatron in 1993 spelled the end of its radiotherapy program, much of the technology and knowhow pioneered by Lab researchers gradually is being transferred to hospitals and laboratories around the world. In the case of the Bevatron's ocular melanoma treatment program, efforts are underway to actually replicate the program at UC Davis using the 70 MeV Crocker Nuclear Laboratory cyclotron.

The new facility, expected to treat about 40 people a year, will open soon. LBL's involvement with the program includes designing and setting up the medical beamline, training personnel, and loaning a dosimetry and computer control system.

Treating an eye tumor with the Crocker Lab's proton beam can save not only lives but unlike conventional surgery, the eye itself. Treatment requires locking in place the patient's head and fixing its position so that the beam strikes the target tumor with absolute precision. Cepeda's contribution was to build a device to precisely position the patient during treatment.

The device, a high-tech chair that adjusts in many directions, can cost upwards of $250,000. Since limited funds existed to design a device, two principals in the project, radiation oncologist Joe Castro and AFRD physicist Tim Renner, turned to Cepeda.

"At times," says Renner, "we forget that there are very creative people throughout the Lab. Mario took it upon himself to design and build this chair. From an engineering standpoint, he had no model to work from, just his nine years experience working with us in the particle radiotherapy program. He built the entire patient positioner out of scavenged parts and pieces of aluminum."

Cepeda said he hand-milled the majority of the approximately 200 parts, purchasing only one part.

"To keep our costs down," he said, "nothing was motorized, although we use pressurized air for one movement. The cylinder that is part of the air drive came from an air-operated door at the Bevatron that is no longer needed. The bearings and shaft under the chair came from the Bevatron Biomed Facility overhead rail system." Another part was scavenged from salvage.

By necessity, Cepeda's device is an object of absolute precision. Tumors in the eye are extraordinarily tiny, typically one centimeter or less in diameter, and can be located next to the optic nerve. Sight is lost if, during treatment, the beam hits the optic nerve. So, the patient positioner must be able to move and hold the patient's head with a wiggle room of less than one millimeter.

For a patient, sitting in this chair at the business end of a proton beam can be a scary experience. Cepeda did what he could to minimize the trauma.

To help immobilize the head, the patient must close his or her mouth on a bite block. By locking the jaw in place, the head too becomes locked in place. But the patient also can suffer feelings of claustrophobia or a smothering sensation. Having observed this, Cepeda designed and machined a bite block that does its job less intrusively.

Cepeda said his past experience with radiotherapy patients helped in the design of the patient positioner.

"The Bevatron clinical program treated people with a number of different diseases, some located in the head, others in the body. I custom-made the devices that immobilized the area of the patient's body that was to be treated. Doing this, I got to see that people not only come in a range of sizes but they have different size heads. Our patient positioner has to work for all patients, and that's a challenge."

The chair was designed, engineered, and assembled based upon Cepeda's hand sketches, which he repeatedly modified and refined. To improve this process, Cepeda spent $6,000 of his own money to purchase a home computer and Computer Assisted Design (CAD) software.

"I'm transferring my sketches of the patient positioner to CAD," he says. "This will make it possible for clinics elsewhere to one day duplicate our device."

Researchers build tabletop x-ray device

By Jeffery Kahn

Since 1988, Life Sciences Division researchers Steve Derenzo and Bill Moses have combed through the world of materials, looking for light-emitting compounds called scintillators. As they searched for better scintillators for detectors used in medicine, science, and industry, they labored under a handicap.

To test candidate materials, Derenzo and Moses traveled to the National Synchrotron Light Source at Brookhaven National Laboratory in New York. The light source allowed them to identify which materials glow when hit with ionizing radiation, and characterize then. But to use the New York facility, Derenzo and Moses had to move and assemble more than a ton of equipment, and make sure it operated during the short window of beamtime allotted them.

Frustrated, the scientists decided to end their reliance on remote facilities. Recently, with electronics engineer Matt Ho and graduate student Stephen Blankespoor, they designed and built a novel pulsed x-ray system which now sits on a tabletop in their Bldg. 55 laboratory. Built in collaboration with Hamamatsu Photonics of Japan, the tabletop device allows immediate evaluation of samples.

"We are looking at inorganic scintillators for the detection of gamma rays," Derenzo says. "Right now, we have no reliable way of predicting what substances are good scintillators. So, we have to actually test materials.

"With better scintillators, we can improve the spatial and time resolution in a variety of detectors and sensors. This would produce not only more detailed images but also images of other phenomena that are not observable with current scintillators."

Positron emission tomography, which records chemical activity in the body, is limited by the performance of available scintillators. PET medical images usually rely on bismuth germanate (BGO) scintillators. LBL's PET scanner, which has the highest resolution in the world, can record structures as small as 2.6 millimeters.

Derenzo and Moses believe they will be able to find new scintillators five times brighter and ten times faster that can double the spatial resolution of the LBL instrument. Likewise, they believe comparable performance improvements are feasible for other scientific detectors that rely on scintillators.

Their new tabletop system will play a key role in the search process. It combines a laser diode and a light-excited x-ray tube. Essentially, the tube is a single-stage photomultiplier with a photocathode and tungsten anode. Light from the laser liberates photoelectrons at the photocathode which then strike the anode, producing x-rays.

Moses says the technique used for testing samples with the tabletop device is fairly simple. "We use the tabletop x-ray source to expose a sample to a short, intense burst of x-rays. Then, we see if the sample glows. This is done with a photomultiplier tube which counts photons."

Thus far during their search for new scintillators, Derenzo and Moses have examined roughly 600 materials. They are winnowing through available compounds looking for materials that are bright, in terms of their light output, but that also are fast.

"Light doesn't just come pouring out of a scintillator instantly," Moses says. "But the shorter the elapsed time between excitation of the scintillator and its emission of photons, the better.

Scintillation is rare in nature as most materials bombarded with ionizing energy dissipate it as heat rather than as light. Previous searches have required crystal samples but because relatively few compounds are readily available as crystals, Derenzo and Moses have devised techniques that allow them to use powder compounds to identify promising materials.

Before a compound can be used in a detector, it must be grown into crystals. Derenzo and Moses discovered that lead sulfate has scintillator properties that could extend the capabilities of PET scanners, but up until now, nobody has figured out how to grow crystals economically on a commercial scale.

Several private companies are working on this project, as is LBL researcher John Apps. The group has measured the properties of some small synthetic crystals of lead sulfate grown by Radiation Monitoring Devices of Watertown, Mass. These were presented at the 1993 IEEE Nuclear Science Symposium in San Francisco.

Women in Science & Engineering Seminar

Darleane Hoffman, of LBL's Nuclear Science Division and UC Berkeley's Department of Chemistry, will be the featured speaker at the next Women in Science and Engineering Seminar, to be held at 12:10 p.m. on Monday, March 7, in Bldg. 70A-3377. Refreshments will be served at noon. All employees are invited to attend.

Hoffman will discuss some recent studies of the chemical properties of the heaviest elements--those appearing beyond uranium in the periodic table.

These elements must be produced at accelerators, and the number of atoms produced is so small and their lifetimes are so short that chemical studies must be performed on an "atom-at-a-time" basis. She will also discuss the feasibilty of performing chemical studies on element 106, the heaviest element, whose discovery was independently confirmed by Hoffman's group in 1993.

The Women in Science and Engineering Seminar Series provides the Laboratory community opportunities to learn about the research of women scientists and engineers, and to discuss career issues and common concerns.

A message from Deputy Director Pier Oddone

An important component of our vision for LBL is creating a work environment that is supportive of all employees. It is only in such a supportive environment that we can expect people to work to their fullest potential. One element of this environment is the policies and systems that permit employees to successfully combine their family and work responsibilities.

Over the last year, Laboratory management and employee groups have invested considerable time and effort on work/family issues. One example of these efforts has been the work of the Child Care Center Committee in proposing and designing a program for childcare at LBL. Currently the Laboratory is conducting a survey of all employees to verify the demand for such a center prior to making a decision to build a childcare facility on site.

There are many other activities that can help support employees in their childcare responsibilities. An employee group that has been very effective in this area is the Work/Family Committee (W/FC).

Working with the Laboratory, it has helped in the development of plans for the childcare center and the creation of databases to provide information on childcare, and has provided a forum for discussion and opportunities for networking.

The latest example of this collaboration between the W/FC and the Laboratory is the upcoming database and workshop on summer childcare/day camps organized by the W/FC in collaboration with the Lab's Employee Assistance Program. Many of us are very familiar with the special challenges and difficulties in arranging our children's summer activities. The proposed workshop and database, as described in the accompanying announcement, should be very helpful to employees whose childcare needs become more complex during summers. I urge you to participate in this workshop and in filling out the questionnaire on your experiences with summer childcare. n

Work/Family Committee

The Work/Family Committee (W/FC) is an employee group that formed nearly a year ago to provide a forum for employees to discuss problems they face due to dependent-care responsibilities and to work together to find creative solutions to those problems.

The W/FC currently has four subcommittees. The Parents Advisory Group meets regularly to discuss parents' ideas about the operating parameters of an on-site childcare center at LBL. The subcommittee on Electronic Networking is completing documentation on how to access an electronic bulletin board that will provide parents at LBL with a means to exchange information on childcare, activities for children in the Bay Area, etc.

The subcommittee on LBL Policies is reviewing LBL policies that may be used by employees with dependent-care responsibilities such as flex-time and telecommuting. The subcommittee on Summer Child Care is working with the Employees Assistance Program to put together a database on summer childcare/day camps used by LBL employees, to distribute information about summer childcare/day camps in the Bay Area, and to sponsor an informal workshop on summer childcare/day camps that will provide the means for LBL employees to share information and discuss needs and concerns regarding finding summer childcare. In the future, the W/FC hopes to form a subcommittee with eldercare concerns as its focus.

If you are interested in participating in any of these subcommittees, please contact the chairperson(s) listed in the box.

The W/FC publishes a bi-monthly newsletter that includes reports from the Child Care Center Working Group, subcommittee reports, and other topics of interest to employees with dependent-care responsibilities.
