Systems, methods, and devices for in vivo ultrasound guidance during arthroscopic surgery
PendingCN122003216AUltrasonic/sonic/infrasonic diagnosticsSurgical navigation systemsArthroscopic procedureUltrasound imaging
Systems and methods are provided for 3D in vivo ultrasound imaging of a tissue surface, such as a tissue surface located within a joint capsule, during an arthroscopic procedure. An in vivo ultrasound probe is provided having a rotatable distal region supporting an array of ultrasound transducers. An ultrasound array is controlled to collect image data at several elevations while rotating the distal region of the probe to acquire a local 3D image data set across a local 3D volume associated with a current probe pose. This process is repeated as the probe pose changes, resulting in a set of local 3D image datasets, each local 3D image dataset corresponding to a different probe pose. The local 3D image dataset is processed to segment a tissue surface profile and generate a corresponding set of surface tiles. The surface tiles are processed and combined to generate a synthetic 3D image, optionally based on input from one or more sensors.
