A recurrent neural network approach for 3d vision-based force estimation
Avilés Rivero, Angélica Ivone; Marbán González, Arturo; Sobrevilla Frisón, Pilar; Casals Gelpí, Alicia; Fernández Ruzafa, José (Institute of Electrical and Electronics Engineers (IEEE), 2014)
Conference report
Restricted access - publisher's policyRobotic-assisted minimally invasive surgery has demonstrated its benefits in comparison with traditional procedures. However, one of the major drawbacks of current robotic system approaches is the lack of force feedback. ... -
An approach for physiological motion compensation in robotic-assisted cardiac surgery
Avilés Rivero, Angélica Ivone; Sobrevilla Frisón, Pilar; Casals Gelpí, Alicia (2014-11-14)
Article
Open AccessThe lack of physiological motion compensation is a major problem in robotic-assisted cardiac surgery. Since the heart is beating while the surgeon carried out the procedure, dexterity of the surgeon’s and precision are ... -
Estimating and understanding motion : from diagnostic to robotic surgery
Avilés Rivero, Angélica Ivone (Universitat Politècnica de Catalunya, 2017-05-18)
Doctoral thesis
Open AccessEstimating and understanding motion from an image sequence is a central topic in computer vision. The high interest in this topic is because we are living in a world where many events that occur in the environment are ... -
Robust cardiac motion estimation using ultrafast ultrasound data: a low-rank topology-preserving approach
Avilés Rivero, Angélica Ivone; Widlak, Thomas; Casals Gelpí, Alicia; Nillesen, Maartje M.; Ammari, Habib (2017-06-21)
Article
Open AccessCardiac motion estimation is an important diagnostic tool for detecting heart diseases and it has been explored with modalities such as MRI and conventional ultrasound (US) sequences. US cardiac motion estimation still ... -
Sensorless force estimation using a neuro-vision-based approach for robotic-assisted surgery
Avilés Rivero, Angélica Ivone; Alsaleh, Samar M.; Sobrevilla Frisón, Pilar; Casals Gelpí, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference lecture
Open AccessThis paper addresses the issue of lack of force feedback in robotic-assisted minimally invasive surgeries. Force is an important measure for surgeons in order to prevent intra-operative complications and tissue damage. ... -
Towards retrieving force feedback in robotic-assisted surgery: a supervised neuro-recurrent-vision approach
Avilés Rivero, Angélica Ivone; Alsaleh, Samar M.; Hahn, James K.; Casals Gelpí, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2017-07-01)
Article
Open AccessRobotic-assisted minimally invasive surgeries have gained a lot of popularity over conventional procedures as they offer many benefits to both surgeons and patients. Nonetheless, they still suffer from some limitations ... -
Unconstrained L1-regularized minimization with interpolated transformations for heart motion compensation
Avilés Rivero, Angélica Ivone; Sobrevilla Frisón, Pilar; Casals Gelpí, Alicia (2014)
Conference report
Restricted access - publisher's policyMotion compensation constitutes a challenging issue in minimally invasive beating heart surgery. Since the zone to be repaired has a dynamic behaviour, precision and surgeon's dexterity decrease. In order to solve this ... -
V-ANFIS for Dealing with Visual Uncertainty for Force Estimation in Robotic Surgery
Avilés Rivero, Angélica Ivone; Alsaleh, Samar M.; Montseny Masip, Eduard; Casals Gelpí, Alicia (Atlantis Press, 2015)
Conference report
Open AccessAccurate and robust estimation of applied forces in Robotic-Assisted Minimally Invasive Surgery is a very challenging task. Many vision-based solutions attempt to estimate the force by measuring the surface deformation ...
