Diagnostic x-ray installation for providing subtraction images |
摘要 |
An exemplary embodiment includes a television pickup installation, image storage circuitry, a difference stage for the subtraction of two chronologically successively obtained image data signals through difference formation and a monitor. An address computer is connected with the output of the difference stage and has outputs connected to the address inputs of the image storage circuitry. The computer alters in a step-wise fashion the allocation of the image point data to be compared in the difference stage (13) until a minimum of the difference formed during the subtraction of two images results.
