Producing high quality cranial SRS plans with 4Pi planning technique in a commercial clinical solution

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To generate high‐quality stereotactic radiosurgery (SRS) plans for single cranial lesions using 4Pi planning technique and compare these to our clinical “status quo” plans. Methods Eighteen vestibular schwannoma (VS) patients previously planned with Varian Eclipse RapidArc and treated on a Varian TrueBeam using 6FFF MV photon beams ...

Surgeons' posture and muscle strain during laparoscopic and robotic surgery

British Journal of Surgery, 2020
It is assumed that conventional laparoscopy (LAP) and robotic‐assisted laparoscopic surgery (RALS) differ in terms of the surgeon's comfort. This study compared muscle workload, work posture and perceived physical exertion of surgeons performing LAP or ...

Accuracy and reproducibility of a single‐pose image‐to‐robot registration method for mobile C‐arm cone beam CT guided histotripsy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Histotripsy is a focal tumor therapy that utilizes focused ultrasound (US) to mechanically destroy tissue. To overcome visualization limitations of diagnostic US‐guidance, C‐arm cone beam CT (CBCT)‐guided histotripsy is being developed, for which a mobile C‐arm could increase accessibility. CBCT‐guided histotripsy uses a phantom with a

Forceps with direct torque control [PDF]

arXiv, 2023
This study presents a conceptual design of laparoscopic forceps whose grasping torque can be directly controlled by the user. By integrating an adjustable constant torque mechanism, the handle opening angle is converted to the grasping torque irrespective of the jaw opening angle.

A Systematic Clinical Framework for Postimplantation Monitoring in Thalamic Neuromodulation: Insights From Twiddler's Syndrome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This case described a 25‐year‐old pregnant woman with refractory multifocal epilepsy, diagnosed in 2020 and treated with bilateral thalamic deep brain stimulation (DBS) targeting the centromedian and pulvinar nuclei. Prior to DBS, she experienced daily focal seizures, often progressing to generalized tonic–clonic seizures despite optimal ...

Learning needle insertion from sample task executions [PDF]

arXiv, 2021
Automating a robotic task, e.g., robotic suturing can be very complex and time-consuming. Learning a task model to autonomously perform the task is invaluable making the technology, robotic surgery, accessible for a wider community. The data of robotic surgery can be easily logged where the collected data can be used to learn task models.

Robotics the future of surgery

International Journal of Surgery, 2008
The frontiers of surgery as we know them are expanding at an astounding pace. As medical students, it is essential that we brace ourselves for what this field may have in store for us when we take our places as surgeons. Developments in technology coupled with the demand for improved patient safety and surgical finesse are fuelling a revolution in the ...
