1. A picture archiving and communication system for ultrasound image data comprising in combination:
- a first group of ultrasound imaging systems connected to generate first image data;
a first data base storage device storing at a first location at least some of the first image data;
a second group of ultrasound imaging systems connected to generate second image data;
a second data base storage device storing at a second location at least some of the second image data;
a central data base storage device connected to store at a third location the first image data and second image data;
a central controller connected to read and write data to the central data base storage device;
a network coupled to the central controller;
a first controller connected to transmit the first image data between the first data base and the central controller over the network and thereafter to delete at least a portion of the first image data from the first data base storage device; and
a second controller connected to transmit the second image data between the second data base and the central controller over the network and thereafter to delete at least a portion of the second image data from the second data base storage device, whereby the first and second image data can be archived on the central data base storage device while at least some of the first image data is deleted from the first data base storage device and at least some of the second image data is deleted from the second data base storage device.

Abstract
Local storage of image data from ultrasound devices is transmitted through local controllers and through a network to a central controller which stores the data in a central data base storage device. The data may be retrieved by the local controllers by the use of separate passwords which are authenticated by central controller.

9. In a picture archiving and communication system for ultrasound image data, a method of storing the data in a data base at a location remote from the locations at which the data is generated comprising the steps of:
-
generating ultrasound first image data at a first location;
storing at least some of the first image data at the first location;
generating second image data at a second location different from the first location;
storing at least some of the second image data at the second location;
transmitting at least some of the first image data from the first location to the data base at a third location different from the first location and the second location;
transmitting at least some of the second image data from the second location to the data base at the third location;
deleting at the first location at least some of the first image data written to the data base at the third location;
deleting at the second location at least some of the second image data written to the data base at the third location;
reading at least some of the first image data from the data base;
transmitting to the first location the first image data read from the data base;
reading at least some of the second image data from the data base;
transmitting to the second location the second image data read from the data base, whereby image data generated at the first and second locations can be stored in a data base at the third location and can be retrieved when needed. - View Dependent Claims (10, 11, 12, 13, 14)
