Abstract
Robust calcification tracking is provided in fluoroscopic imagery. A patient with an inserted catheter is scanned over time. A processor detects the catheter in the patient from the scanned image data. The processor tracks the movement of the catheter. The processor also detects a structure represented in the data. The structure is detected as a function of movement with a catheter. The processor tracks the movement of the structure using sampling based on a previous location of the structure in the patient. The processor may output an image of the structure.
Claims20
A method for structure detection, the method comprising:
- scanning, over time, an object having an inserted catheter;
- detecting by a processor, the catheter as represented in data from the scanning;
- tracking, by the processor, a movement of the catheter;
- detecting, by the processor, a structure represented in the data from the scanning, the structure detected as a function of movement with the catheter;
- tracking by the processor, the structure represented in the data from the scanning, the tracking using sampling based on a previous location of the structure;
- and
- outputting, by the processor, an image of the structure.
A system for object detection over time in a structure having an inserted catheter, the system comprising:
- a scanner configured to image the structure containing the inserted catheter over time;
- a processor configured to detect and track the catheter as represented in data from the imaging;
- the processor configured to further detect and track an object represented in the data from the imaging, the object detected based on its linear motion correlation with the inserted catheter, wherein the object is tracked using sampling based on a previous location of the object;
- and
- the processor configured to output an image of the object.
A non-transitory computer readable storage medium having stored therein data representing instructions executable by a programmed processor for facilitating detection of an object in a patient, the storage medium comprising instructions for:
- scanning over time a patient having an inserted pig tail catheter;
- detecting the pig tail catheter as represented in data from the scanning;
- tracking a movement of the pig tail catheter;
- detecting a structure represented in the data from the scanning, the structure detected based on its linear motion correlation with the inserted catheter;
- tracking the structure represented in the data from the scanning, the tracking using sampling based on a previous location of the structure;
- and
- outputting an image of the structure.
