Abstract

An ultrasonic diagnosis apparatus capable of interchangeably using a plurality of probes each having ultrasonic transducer elements disposed in an array and being detachably connected to the apparatus via a connector, wherein a storage unit is provided in the probe for storing data associated with the elements disposal configuration or control information on scanning or focusing, and a controller provided in the ultrasonic diagnosis apparatus accesses the storage unit via the connector to read the element disposal configuration data or the control information and perform a control operation of picking up an image in accordance with the read-out data.

Claims

1. An ultrasonic diagnosis apparatus capable of probe exchange comprising:

an image forming unit having a first connector;

a probe having a plurality of ultrasonic transducer elements disposed in a predetermined configuration;

means including a second connector associated with the probe for electrically connecting and disconnecting said probe from said image forming unit connector;

storage means physically associated with the probe for storing control information and read-out imaging procedure information unique to said probe;

said image forming unit including a control means for reading information stored in the storage means associated with said probe, said control means being connected through said connectors to control said transducer elements when transmitting signals; and

means responsive to signals received from said transducer through said connectors for forming an image using the read-out imaging procedure information.

2. An ultrasonic diagnosis apparatus capable of probe exchange according to claim 1, wherein the probe has a housing and wherein said storage means is located in said probe housing at a position adjacent said ultrasonic transducer elements.

3. An ultrasonic diagnosis apparatus capable of probe exchange according to claim 1, wherein storage means is located in said second connector.

4. An ultrasonic diagnosis apparatus capable of probe exchange according to claim 1, wherein said image forming unit has a second storage means for temporarily storing said imaging procedure information read-out from said probe storage means.

5. An ultrasonic diagnosis apparatus including an image forming unit adapted for use with a plurality of probes that can be interchangeably used wherein each of said probes has:

a plurality of ultrasonic transducer elements disposed in a predetermined configuration and connected to signal lines;

a connector for detachably and electrically connecting one of said probes to said image forming unit; and

a storage means for storing data uniquely related to the transducer element disposal configuration of said probe; and

wherein the image forming unit comprises;

element selection means for selecting certain ones of said signal lines connected to said transducer elements;

transmitting means for applying a drive signal to each of said selected signal lines;

means for delaying signals received from said transducer elements via said selected signal lines and for adding together said delayed received signals in the same phase; and

control means for an imaging procedure wherein the control information in said probe is used to effect a transducer element selection sequence by said element selection means.

6. An ultrasonic diagnosis apparatus capable of probe exchange according to claim 5, wherein said control information in said probe includes also data for delay amount for signals received from said transmitting means.

7. An ultrasonic diagnosis apparatus capable of probe exchange according to claim 5, wherein said image forming unit has a second storage means for temporarily storing said imaging procedure information read-out from said probe storage means.

8. An ultrasonic diagnosis apparatus including an image forming unit adapted for use with a plurality of probes that can be interchangeably used wherein each of said probes has:

a plurality of ultrasonic transducer elements disposed in a predetermined configuration and connected to signal lines;

a connector for detachably and electrically connecting one of said probes to said image forming unit; and

a storage means for storing control information uniquely related to the transducer elements in said probe; and

wherein the image forming unit comprises;

element selection means for selecting certain ones of said signal lines connected to said transducer elements;

transmitting means for applying a drive signal to each of said selected signal lines;

means for delaying signals received from said transducer elements via said selected signal lines and for adding together said delayed received signals in the same phase; and

control means for an imaging procedure wherein said means generates signals which serve as means for controlling an amount of delay for said transmitting means.

9. An ultrasonic diagnosis apparatus capable of probe exchange according to claim 8, wherein said control means generates further signals related to transducer element disposal configuration in said probe.

10. An ultrasonic diagnosis apparatus capable of probe exchange according to claim 8, wherein said image forming unit has a second storage means for temporarily storing said imaging procedure information read-out from said probe storage means.
