Ultrasonic probe recognition methods based on monobus communication and ultrasonic medical equipment
Technical field
This application involves Ultrasonic Diagnosis field more particularly to a kind of methods and apparatus with identification ultrasonic probe.
Background technology
Ultrasonic diagnostic equipment can all match more than one ultrasonic probe, and different ultrasonic probes can be because of checkup item not
Together, it needs to select suitably to pop one's head in.The ultrasonic probe correctness of selection influences the accuracy of diagnostic result great.In general,
In order to distinguish different types of ultrasonic probe, the corresponding coding of probe or identifier can be given, commonly referred to as pop one's head in ID
(identification data).The ID that pops one's head in passes through corresponding data line in cable of popping one's head in through the internal Classical correlation circuit of probe
The identification maneuver of probe is completed with ultrasonic main-machine communication.Existing identification technology is segmented into two types:
One, passive discerning:The level signal for representing probe ID, different level or level are pre-set inside probe
Combination can represent different probes.This mode only needs host query to pop one's head in, and probe need not respond host, therefore is known as
Passive discerning.Passive discerning project plan comparison is easy to use, but the information content transmitted is very limited, cannot be satisfied present diversification
Information requirement.
Two, initiative recognition:There is corresponding identification circuit inside probe, the identification circuit storage inside ID letters of the probe
Breath.By being in communication with each other the probe id information obtained inside identification circuit between ultrasonic host and probe.Initiative recognition scheme
Relatively intelligent, mode is more flexible, and the information content of storage can be freely arranged.Initiative recognition scheme by communication mouth line number can be divided into
More mouth line communication modes and monobus communication mode.And in the initiative recognition scheme of monobus communication at present, it is typically necessary outer
Memory and crystal oscillating circuit are connect, thus structure is more complex.
