Computer-assisted interventions (CAI) is a field of research and practice, where medical interventions are supported by computer-based tools and methodologies. Examples include:

  • Medical robotics
  • Surgical and interventional navigation
  • Imaging and image processing methods for CAI
  • Clinical feasibility studies of computer-enhanced interventions
  • Tracked and guided biopsies
  • Alignment of pre-procedure images with the patient during the procedure
  • Intraoperative decision supports
  • Skill analysis and workflow studies in CAI
  • Clinical studies of CAI showing first-in-man or early efficacy results
  • User interfaces and visualization systems for CAI
  • Surgical and interventional systems
  • Novel surgical devices and sensors
  • User performance studies
  • Validation and evaluation of CAI technology

The basic paradigm of patient-specific interventional medicine is a closed loop process, consisting of

  1. combining specific information about the patient with the physician's general knowledge to determine the patient's condition;
  2. formulating a plan of action;
  3. carrying out this plan; and
  4. evaluating the results.

The experience gathered over many patients may be combined to improve treatment plans and protocols for future patients. Computer-based technology assists medical professional in processing and acting on complex information .[1]

Surgical process modeling and analysis

In order to gain an explicit and formal understanding of surgery, the field of analyses and modelling of surgical procedures has recently emerged. The challenge is to support the surgeon and the surgical procedure through the understanding of Operating Room (OR) activities, with the help of sensor- or human-based systems. Related surgical models can then be introduced into a new generation of Computer-Assisted Interventions systems to improve the management of complex multimodal information, improve surgical workflows, increase surgical efficiency and the quality of care in the OR. Models created by these different approaches may have a large impact in future surgical innovations, whether for planning, intra-operative or post-operative purposes.[2]

This idea of describing the surgical procedure as a sequence of tasks was first introduced by MacKenzie et al. (2001).[3] and formalised in Jannin et al., 2001.[4] The term Surgical Process (SP) has been defined as a set of one or more linked procedures or activities that collectively realise a surgical objective within the context of an organisational structure defining functional roles and relationships.[5] This term is generally used to describe the steps involved in a surgical procedure. A Surgical Process Model (SPM) has been defined as a simplified pattern of an SP that reflects a predefined subset of interest of the SP in a formal or semi-formal representation. It relates to the performance of an SP with support from a workflow management system.

Surgical process models are described from observer based acquisition,[5][6] or sensor-based acquisition (such as signals,[7][8][9][10][11] or videos,[12][13][14]).
