Not sure really, its impossible to say if those technologies would have been developed without NASA being involved.
Very often technology follows complex pathways, often parallel, no one person or organisation can really claim the full credit.
As noted previously, many of the claimed spinoffs on Kmar's list are so broad as to be meaningless.
Many of the inventions attributed to NASA in fact have nothing to do with them, the same goes for Bell Labs.
Whether NASA really gives value for money I very much doubt.
Like I said expediency is important when developing leading edge technology. I've more than sufficiently given evidence of tangible value for the money. If you're interested you can trace the expicit connections between the spinoff's and their everyday practicile use.
The Digital Cardiac Imaging (DCI) System answers this demand by incorporating image processing technology first developed for NASA's Earth remote sensing satellites. Designed by Philips Medical Systems International, The Netherlands, and marketed in the U.S. by Philips Medical Systems North America Company, Shelton, Connecticut, the DCI offers much sharper real-time images. It is the most widely used digital cardiac imaging system, according to the manufacturer, with more than 300 units in operation worldwide, including over 100 in the U.S.
The Philips system gives the cardiologist direct control of "roadmapping," in which freeze-frame images of a blood vessel section aid in guiding the catheter. Using a cordless control unit such as a remote TV channel selector, the cardiologist can manipulate images to make immediate assessments, compare live x-ray and road map images by placing them side-by-.side on monitor .screens, or compare pre- and post-procedure conditions. The additional information allows the doctor to get into and out of the heart more quickly, minimizing trauma.
The image processing technology employed by the DCI originated some 15 years ago at International Imaging Systems (I2S), Milpitas, California. 12S pioneered optical, analog, and digital image processing equipment for NASA's Earth resources survey spacecraft, exemplified by the Landsat satellite family. In the early 1980s, 12S responded to emerging interest within the medical industry for such applications as ultrasound, computer-aided tomography (CT), and magnetic resonance imaging (MRI) body scanners. I2S supplied medical equipment firms with image processing hardware and software identical to that used by NASA. Subsequently, I2S broadened its market and developed application-specific products for its industrial clients, including a high-performance processor for Philips Medical's DCI system.
Miniaturized space technology detects a broad range of spontaneous heart arrhythmias
Sudden cardiac death (SCD) strikes nearly half a million Americans each year. Eighty percent die before medical help arrives and those who survive face a two-year recurrence rate that may be a as high as 55 percent. For many potential victims, however, the Automatic Implantable Cardioverter Defibrillator, or AICD* (shown at right) offers new hope: it can reduce the two-year SCD mortality rate to less than three percent.
The AICD incorporates spacebased miniaturized electronics to detect a broad range of spontaneous heart arrhythmias, including those caused by ventricular fibrillation, during which the heart loses its ability to pump blood, causing death or brain damage in minutes.
The AICD pulse generator was developed in the early 197Os by Intec Systems Inc. and Medrad Inc., Pittsburgh, PA, in conjunction with researchers at Sinai Hospital, Baltimore, Maryland. NASA funded development of an AICD recording system and an independent design review of the system, both conducted by the Applied Physics Laboratory of Johns Hopkins University, Howard County, Maryland. The first model was successfully implanted in a dog in 1976 and, after 12 years and more than $4 million in research, the device was implanted in a 57-year-old woman at Johns Hopkins Hospital on February 4, 198O. Clinical studies ensued and a grant from NASA enabled Intec Systems and the Applied Physics Laboratory to pursue development of more advanced models.
The AICD is manufactured by Cardiac Pacemakers, Inc., St. Paul, Minnesota, a subsidiary of Eli Lilly and Company, which purchased Intec Systems in 1985. CPI was the first company to receive FDA approval for an implantable defibrillator and continues to work to make this lifesaving technology available to a greater number of patients.
Adopting infrared sensor technology developed for space missions,the Diatek Corporation of San Diego, Calif., produced an aural thermometer that gauges body temperature in two seconds or less. Accurate to within two-tenths of a degree, the Model 7OOO thermometer measures heat emitted from the patient's tympanic membrane, or eardrum.
We all know that you're not really interested though. You're just trying to get out of the corner you've backed yourself in to.
There's also the intangibles and not-so-immediates which are even potentially more valuable if we continue our quest to explore our universe.

"In fact, all the gold, cobalt, iron, manganese, molybdenum, nickel, osmium, palladium, platinum, rhenium, rhodium and ruthenium that we now mine from the Earth's crust, and that are essential for our economic and technological development, came originally from the rain of asteroids that hit the Earth after the crust cooled.

That wasn't the question.
The question was whether money 'invested' in NASA could be better invested elsewhere, all we have is the figures for NASA, no comparisons.
Really? That's ALL we have? There's no example of wasted government spending?
