A pattern generator and controller arrangement operates for controlling the component parts of an MRI system. The arrangement comprises a plurality of channels including a main control channel and output channels. The arrangement receives instructions from the system CPU which then leaves the control and outputting to the arrangement, thereby avoiding the necessity of a large expensive CPU to operate the system with versatility and speed.

Method for controlling radio frequency excitation and gradient pulse

A split screen imaging display system including interactive controls operating on random access memories for designating subdisplay images on a split screen basis. The interactive controls in conjunction with random access memories individually control each of the split screen subdisplay images with an independant set of parameters which are variable even during the imaging process.

Radio frequency excitation and gradient pulse controller having

A windowing system for use when using data to form video display images. The digital data is operated on by a transfer function delineated by predefined parameters or by newly generated parameters determined by the image being displayed.

Intensity level windowing system for image displays

Improved diagnostic imaging methods and systems for automatically controlling variable parameters used when translating detected radiation intensities caused by radiation that has passed through an object and impinged on a detector to fixed values for display images by determining the maximum and minimum intensities at the impinged on detector locations and adjusting the parameters as functions of the said maximum and minimum intensities.

Systems and methods for translating radiation intensity into pixel values

Equipment and methods are presented for rearranging divergent beam derived data into parallel data to enable decreasing the number of preprocessing computations and improving the quality of the resulting tomograph. The equipment and method comprise means and steps which vary the spacing of at least portions of the resulting parallel projections, so that when the parallel projections with varied spacings are combined with the parallel projections that have not had their spacing varied, the cupping artifacts normally present when using projections obtained from rearranging are cancelled.

Combining rebinned and unrebinned parallel ray data with unequal lateral

A system for converting video camera images, obtained when the camera scans radiation generated images, to frames of electrical signals; the radiation generated images are obtained responsive to pulses applied to activate a radiation source during pulse periods; the system applies the pulses at a rate of at least 15 per second and means are provided for reading out the frames at a rate of at least 15 per second.
