Ultrasonically marked instruments for ultrasound-guided interventions

Abstract: In order to enhance needle and catheter visibility under ultrasound and enable tool tracking, it has been proposed to embed ultrasound receivers near the tip of interventional tools. Using these sensors to receive and analyze signals coming from the imaging probe as its beams sweep the field of view, the position of the sensor can be estimated with <0.5mm accuracy even when the tool tip is invisible in the pulse-echo image. One crucial design parameter for these ultrasonically marked instruments is the sensiti… Show more

“…CSNP‐PDMS fiber‐optic OpUS transmitters, engineered through two distinct reproducible fabrication routes, demonstrated clinically useful peak‐peak ultrasound pressures (>3 MPa) and bandwidths (>29 MHz) and performed ex vivo imaging of brain tissue at deep imaging depths of beyond 8 mm. These results show that miniaturized OpUS transducers have strong potential to be integrated with the devices that are used in neurological interventions [ 62–65 ] and to provide structural information to surgeons.…”

“…This highlights the potential of CSNP-PDMS nanocomposites for minimally invasive all-OpUS imaging as demonstrated by the all-optical B-mode ultrasound images of a lamb cerebellum and cerebrum. Several minimally invasive surgical procedures such as deep-brain stimulation [62,63] and tumor biopsy [64,65] require ultrasound imaging guidance and miniaturized OpUS transducers have strong potential to guide neurological surgical interventions in these contexts.…”

“…[7][8][9] To improve visibility and help in determining the position of devices under ultrasound imaging, solutions that involve using an ultrasound transducer attached to a device has been proposed. [10][11][12][13][14][15][16][17] A small ultrasound transducer is attached to the tip of a device, and the position of the device is measured with the signal emitted or received by the transducer. Though this concept has existed for about 30 years, [10][11][12] it is recently attracting attention because of the progress in fiber-optic ultrasound transducers.…”

“…One implementation of this method involves transmissions from the imaging probe that are received by a piezoelectric US sensor integrated within the needle [3][4][5]. In recent studies by Xia et al, sequential transmissions by individual elements of the imaging probe were received by a fibre-optic hydrophone (FOH) sensor within the needle lumen [6][7][8][9].…”
