Mekki L, Sheth N, Vijayan R, Rohleder M, Sisniega A, Kleinszig G, et al.
Phys Med Biol
. 2023 Sep;
68(21).
PMID: 37774711
. Surgical guidewires are commonly used in placing fixation implants to stabilize fractures. Accurate positioning of these instruments is challenged by difficulties in 3D reckoning from 2D fluoroscopy. This work...

. 2023 May;
9902:124-132.
PMID: 37195053
A 3D-2D image registration method is reported for guiding the placement of surgical devices (e.g., K-wires). The solution registers preoperative CT (and planning data therein) to intraoperative radiographs and computes...

. 2022 Nov;
68(1).
PMID: 36317269
. Target localization in pulmonary interventions (e.g. transbronchial biopsy of a lung nodule) is challenged by deformable motion and may benefit from fluoroscopic overlay of the target to provide accurate...

Proc SPIE Int Soc Opt Eng
. 2022 Sep;
11598.
PMID: 36090307
Purpose: A method and prototype for a fluoroscopically-guided surgical robot is reported for assisting pelvic fracture fixation. The approach extends the compatibility of existing guidance methods with C-arms that are...

Proc SPIE Int Soc Opt Eng
. 2022 Sep;
11315.
PMID: 36082206
Purpose: We report the initial development of an image-based solution for robotic assistance of pelvic fracture fixation. The approach uses intraoperative radiographs, preoperative CT, and an end effector of known...

Med Image Anal
. 2020 Dec;
68:101917.
PMID: 33341493
Purposes: Surgical reduction of pelvic fracture is a challenging procedure, and accurate restoration of natural morphology is essential to obtaining positive functional outcome. The procedure often requires extensive preoperative planning,...

Phys Med Biol
. 2020 May;
65(16):165012.
PMID: 32428891
Metal artifacts present a challenge to cone-beam CT (CBCT) image-guided surgery, obscuring visualization of metal instruments and adjacent anatomy-often in the very region of interest pertinent to the imaging/surgical tasks....

Han R, Uneri A, Ketcha M, Vijayan R, Sheth N, Wu P, et al.
Phys Med Biol
. 2020 Mar;
65(13):135009.
PMID: 32217833
Surgical reduction of pelvic dislocation is a challenging procedure with poor long-term prognosis if reduction does not accurately restore natural morphology. The procedure often requires long fluoroscopic exposure times and...

Phys Med Biol
. 2019 Mar;
64(9):095022.
PMID: 30921783
Percutaneous screw fixation in pelvic trauma surgery is a challenging procedure that often requires long fluoroscopic exposure times and trial-and-error insertion attempts along narrow bone corridors of the pelvis. We...

. 2018 Oct;
63(21):215016.
PMID: 30372418
Real-time fusion of magnetic resonance (MR) and ultrasound (US) images could facilitate safe and accurate needle placement in spinal interventions. We develop an entirely image-based registration method (independent of or...
