around the certificate of need restrictions in place at the time. The Delta 2000 series, introduced in 1977, included Delta 2005, Delta 2010, Delta 2020, Delta 2060 and Delta 2060 Quantum. These scanners could scan the body in 2–5 seconds, thereby eliminating motion artifacts due to breathing. The HPS 1440 scanner was introduced in 1985 as an ultra high resolution CT scanner. These scanners were of the fourth generation design, in which there was a stationary ring of detectors and the x-ray tube rotating inside the detector ring. One of the 2020 systems was operate at Brigham and Women's Hospital attempting cardiac gated imaging. Also in the product line were DeltaMat, a multiformat camera and DeltaPlan, a radiation therapy planning system using CT cross sectional images to plan radiation therapy treatments. These products were marketed in the 1977 to 1985 timeframe. The DR 960 was introduced in 1982 as a digital subtraction angiography device. Rather than injecting contrast material into an artery, contrast was injected into the corresponding vein. A digital image was acquired without contrast and one with, and the images subtracted from each other leaving the arterial branch highlighted with contrast. The company also marketed an MRI (called Nuclear Magnetic Resonance, or NMR at the time) unit, the Teslacon, beginning in 1984. Teslacon products ranged in magnetic field strength from 0.15 to 1.5 tesla. David Flugan and Robert Gauss were the chief thinkers and the 'brain trust' behind the implementation of Technicare's MRI product line. Their names ring prominent among the inventors of early MRI sub parts. J&J continued supporting the continued development of the HPS 1440 and Teslacon II MRI systems until the end of 1987.
