Three dimensional (3-D) medical diagnostic imaging appears to be one of the major technical advancements of this decade. It is being pursued vigorously by the industry and is technologically feasible. However, cost versus performance issues are currently extremely sensitive, and are holding back commercialization of a number of 3-D technical concepts. The technical approach detailed in this (Guided Therapy Systems Inc.) report will allow commercialization of a thoroughly needed 2-D acquisition system (2-D probes and controller modules), which are uniformly recognized as a critical part of a 3-D ultrasound imaging system. Any commercially viable system has an architecture driven primarily by cost and performance issues. 2-D phased and linear arrays would certainly meet the performance requirements, should the major technological obstacles be surmounted. A large number of research papers are devoted to resolve such issues, however the cost and considerations for such arrays, with thousands of elements to interconnect and drive, have not been resolved to date. This research shows the feasibility of achieving a balance between cost and performance for 2-D probes, by utilizing electronic arrays and integrated control modules, with a mechanically driven compact 2-D imaging probe.

ABSTRACT. Proper use of medical imaging tools requires knowledge of their associated radiation risks, as well as their possible benefits. The authors assessed physicians’ knowledge of the radiation risks associated with bone scintigraphy (bone scan) during an annual meeting of the Israeli Orthopedic Society. The mortality risk of radiation-induced carcinoma from bone scan was identified correctly by less than 5% of respondents. The most frequent answer (38.4%) was the option that was least correct. Senior orthopedists estimated lower risks than did residents. Overall, respondents grossly underestimated the potential radiation risk from bone scan.

IONIZING RADIATION from occupational exposures is subject to strict international regulations. The regulations, derived from a linear model, (1) set annual occupational exposure limits at 20 mSv (2 rem). (2) Annual ionizing radiation exposure limits for the general public are set at 1 mSv (0.1 rem). Assuming the dose is delivered incrementally, 1 mSv carries a 4/100,000 chance of producing a fatal cancer. A person exposed annually to 1 mSv for 60 yr has a 60 times greater risk for cancer (or 24/10,000). (3)

Regulations limiting exposure to ionizing radiation do not apply to patients undergoing medical evaluation or treatment. The responsibility for deciding whether a patient should undergo radiotherapy is delegated to the physician, who has to compare the benefit of the procedure with the expected risk involved. This judgment requires the physician to have a clear knowledge of the ionizing radiation risks associated with specific imaging techniques. (4)

Physicians usually conceptualize the radiation dose associated with a specific medical imaging test by comparing the test to a standard: the chest radiograph (x-ray). For example, computerized tomography (CT) of the lumbar spine has a radiation dose equivalent to 250 chest x-rays (5 mSv), (5) and bone scintigraphy (bone scan) has a dose equivalent to 200 chest x-rays (4.2 mSv). (6) The authors hypothesized that orthopedists may not be aware of the radiation hazards associated with the imaging tests they commonly use in their practices. To assess their level of knowledge about one of these tests, we administered a short questionnaire on the risks of bone scan at an annual meeting of the Israeli Orthopedic Society.

L.A.’s major medical centers are undergoing a building boom in expanded and enhanced imaging facilities amid a continuing debate in health care circles about whether MRIs and other scanning equipment have been overused.

Tens of millions of dollars are being invested in the new machinery at Cedars-Sinai Medical Center, Good Samaritan Hospital, UCLA Medical Center and USC University Hospital, among others. With high-end magnetic resonance imaging sometimes costing patients more than $1,000, these services have become significant revenue producers for hospitals — especially for outpatients.

“Imaging technology has been expanding almost at the same rate of Moore’s law — it’s doubling every 18 months or so’ said John Relic, who is overseeing the development of Good Samaritan’s center. “And we are taking the position of making sure we provide the best technology available.”

The pace of technological advancement has accelerated in recent years, with imaging machines capable of detecting many more diseases faster than ever. This has prompted unprecedented demand by both patients and doctors for the screenings.

But while the benefits are undeniable, there are questions about the necessity of many of the procedures, along with concerns that increasing the availability of such scanning will lead to unnecessary testing.

A recent report by the BlueCross BlueShield Association found that hospital outpatient costs, which include the provision of imaging services to patients who are not admitted, are the fastest growing component of skyrocketing health care costs.

“There is little doubt this is one of the contributing factors to an upward push in cost,” said Dr. Michael Belman, a medical director at Blue Cross of California, a division of Well-Point Health Networks Inc. and the largest for-profit health insurer in California.

Belman said that when hospitals and other providers expand the availability of new technology, it tends to get used, whether it is needed or not. “Availability is the clear factor,” he said.

‘Cheating’ death’

Dr. Barry Pressman, chair of the department of imaging at Cedars-Sinai, concedes that as much as 20 percent of all imaging may be unnecessary, but adds that those costs are outweighed by the benefits of making faster, more accurate diagnoses — and thus making unnecessary expensive, invasive procedures. “There are cost savings in getting the patient through the system faster, and getting them back to work faster,” he said.

Marconi Medical Systems, Cleveland, entered into a two-year agreement with Huestis Medical to distribute its remanufactured imaging equipment to hospitals and imaging centers in the U.S. and Canada.

Under the agreement, Marconi’s Health Care Products (HCP) division will distribute Huestis’ remanufactured AMX portable X-ray units and C-arms. Marconi said the agreement will result in a “multimillion-dollar gain in annual incremental sales” for Marconi HCP.

“A Huestis Medical remanufactured unit offers a 40% to 60% savings over new systems,” said Gerry Doherty, Marconi HCP senior marketing manager.

Marconi said Huestis’ remanufactured equipment carries performance guarantees and safety features that meet or exceed original equipment manufacturer specifications.

“Our partnership with Marconi furthers our market presence in imaging centers,” said Michael Doherty, chairman of Huestis Medical.
