Definitions[ edit ] Surgery is a technology consisting of a physical intervention on tissues. As a general rule, a procedure is considered surgical when it involves cutting of a patient's tissues or closure of a previously sustained wound.

Dubold shut off the rockets, while Mansell leaped to the telescope. Dubold narrowed the detector beam to a tiny spear of electron stream, and turned to the screen.

The feed-back of that narrowed beam would detect a tiny mass a thousand miles out in space through the disturbance of its flowing electrons and locate it in space as accurately as if sighted by a gun.

At the intersection of the cross-bar lines a tiny shadow showed like a blot of ink in its intensity. Yet Mansell could see nothing. Mansell changed the course of the ship slightly and the clangor ceased.

Dubold shifted the needle beam a bit and located the mass again. A lightning calculation by Mansell told them that the mass was at least fifteen hundred miles ahead.

Its detection informed them that the mass was large enough to be seen with the naked eye. Mansell and Dubold looked at each other doubtfully, but Shafton was not watching them. Instead, he had his eyes glued to the gravitator as if he could not believe what he saw.

However, we are out of its path A flicker of alarm crossed his sharp-cut features as his attention riveted upon the young spaceman's face. For Shafton's eyes were staring aghast into the gravitator's dial.

There must be something wrong. So sensitive were the spacemen's sensations to gravitational pulls out there in almost weightless space, a slight but decided tug toward the prow could be felt. Again the commander scanned the surrounding space.

Thrilling Wonder Stories April The mass ahead tripped the gravity detectors. They had to drop below the speed of light, so that their search beams could guard them from collision.

And that strange cloud grew. There was nothing we could see with the tele-periscopes, but the gravity detectors betrayed an invisible object of fifty thousand tons, approaching behind us—as if it had followed us from Neptune.

The deflector fields wouldn't swing it an inch. Larry Cho is at a research facility on Pluto, where they have a gravitational generator in the form of a giant ring around the moon Charon. Aliens are invading the solar system using advanced gravidic technology. Larry has to reconfigure the generator into a gravity telescope.

The Ring was not merely an accelerator. In theory, it could be configured as a gravity-imaging system, a gravity telescope of enormous sensitivity.

Such a scope could do more than collect gravity waves. It could form images out of them. No one had ever tried it.

Larry decided it was time to test the theory. He needed an imaging sequence of the Moon and vicinity. The facilities on Venus, Ganymede and Titan were all picking up strong gravity waves from the Moon, but their gear was not powerful or sensitive enough to resolve that data into a clear picture.

The Lunar gravity sensors were, of course, completely swamped by the mystery gee waves. In short, none of the other gravity-sensor-equipped stations were able to form a useful image. Nor did they have the benefit of Larry writing their imaging programs.

The monitor screen signaled that the reconfiguration was complete, and Larry powered up the display tank, his thoughts much more on aliens than on what he was doing. It never dawned on Larry that he had quite casually invented a whole new way of looking at the Universe. All he had been after was a practical way to examine the situation around Earth.The Center for Research and Innovation offers comprehensive and fully regulatory compliant clinical research services, including.

A state-of-the-art imaging and radiation oncology core laboratory; Collaborations with world leaders in novel imaging processes and radiotherapy delivery. The two main functions of sensors are navigational and tactical.

Navigational sensors are used by the astrogator to determine the spacecraft's current position, vector, and heading. They are also used by the pilot to perform the maneuvers calculated by the astrogator.
