摘要： A position tracking method using a quasi-DC magnetic field and an apparatus thereof are provided to track the position and orientation of a target by using the quasi-DC magnetic field, and thus to provide eddy current immunity characteristics of a DC system. In a position tracking method using a quasi-DC magnetic field, a periodic magnetic field having a positive polarity phase and a negative polarity phase having a constant positive and negative amplitude respectively is generated around a sensor(34). First and second field measurement signals are generated in response to the magnetic field among the positive and negative polarity phase. Position of the sensor is determined in response to the first and second field measurement signals.

摘要： A software product for a three-dimensional cardiac image using an ultrasonic contour reconstruction is provided to allow a surgeon to perform a complex operation more easily by using a three-dimensional cardiac image. A software product for a three-dimensional cardiac image using an ultrasonic contour reconstruction includes a computer-readable medium. Program commands are stored in the computer-readable medium. When the commands are read by a computer, the computer obtains a plurality of ultrasonic images of an anatomic structure by using an ultrasonic sensor at a plurality of spatial positions. The computer measures position and orientation coordinates of the ultrasonic sensor at the plurality spatial positions, and marks an interest-contour part which represents characteristics of the anatomic structure of at least one ultrasonic image. The computer forms a three-dimensional model of the anatomic structure based on the interest-contour part, the measured position, and the orientation coordinates.

摘要： A display of a catheter tip having a beam direction for an ultrasonic system is provided to reduce an operation time of a surgeon by using a three-dimensional ultrasonic image in performing a complex operation. A catheter(28) includes a position sensor and an ultrasonic imaging sensor. A positioning processor is connected to the catheter(28) to determine position information of a part of the catheter(28) based on an electrical signal transmitted by the position sensor. An image processor(42) is operationally connected to the catheter(28), the positioning processor, and a display unit(44). The position sensor transmits an electrical signal which represents position information of a part of the catheter(28) within a patient body. The ultrasonic imaging sensor transmits ultrasonic energy to an object within the patient body, and receives an ultrasonic reflective sound reflected from the object within the patient body. The image processor(42) displays a catheter icon on the display unit(44) in the same orientation as an orientation of the catheter(28) within the patient body based on the position information induced from the position sensor. The image processor(42) generates an ultrasonic image of the object based on the signal transmitted by the ultrasonic sensor. The image processor(42) displays the generated ultrasonic image in real-time on the display(44) in the same orientation as an orientation of the catheter(28) within the patient body based on the position information induced from the position sensor.
