PIGA (Precise Intelligent Guide Arm) is a Robotic Tool Positioner for CT guided interventions
• CT guided FNA (Fine needle Aspiration) and Needle Biopsy techniques for characterizing tissues
• RF Ablation and other needle based procedures done under CT scan
• Many other CT guided percutaneous procedures
Constraints in the current CT Guided FNA/ Needle Biopsy approach
Currently the above mentioned procedures are performed under the guidance of an imaging modality like Ultrasound or CT scanners. The nature of organs like Lungs, Bones and a few structures in Abdomen prohibit the use of Ultrasound for guided procedures. In such scenarios CTscanners are the only options to guide positioning of the Needle.
Currently Most of the CT guided procedures are done using free hand technique and have one of the following constraints
This is further complicated in case of the lesion being located in a small cavity in the abdomen with limited approach or locations where angulated approach is required or Lesions with adjoining blood vessels / other Critical organs.
Patient / Clinician is subjected to continuous radiation during the procedure which can be
Continuous CT fluoroscopy procedures load the CT tubes heavily and can have impact on the life of CT tube.
