Method and apparatus for managing peripheral devices in a medical imaging system
First Claim
1. A medical diagnostic imaging system comprising:
- an image data acquisition system for generating digital data representative of an image of a subject of interest;
a control system coupled to the image data acquisition system for regulating acquisition of the data; and
a peripheral device coupled to and controlled by the control system, the peripheral device including a memory circuit and an interface circuit, the memory circuit being configured to store parameter data descriptive of a characteristic of interest of the peripheral device, the interface circuit being configured to access the parameter data and to transmit the parameter data from the peripheral device upon demand.

Abstract
A technique for managing data relating to peripheral devices and subsystems in an imaging system includes providing memory circuitry and, where desired, signal processing circuitry resident in the peripheral devices. Manufacturing data, identification data, service record information, calibration data, and other relevant information may be stored directly in the peripheral devices. The circuitry of the peripherals and subsystems may also include sensors and encryption circuits, and circuits for interfacing the memory and processing circuitry with other components, particularly a controller for an imaging system. The peripherals may include coils and drivers for MRI systems, tables, patient monitors and any other device pertinent to an MRI system. An initialization sequence is performed upon connection of the peripheral to the system, to identify the peripheral and to transfer information needed for examination sequences and other MRI procedures.
