Embodiment Construction

[0018] The following relates to systems for providing guidance to medical imaging equipment operators during medical imaging exams and creating quality assurance (QA) records of medical imaging exams to facilitate operator training, data mining to improve workflow, post-exam reviews, and the like.

[0019] The illustrative system represents a magnetic resonance imaging (MRI) examination workflow as a state machine. This flexible representation allows a wide range of run-to-run variance to be represented by providing states and state transitions to represent the various paths that may be followed in any instance of an MRI examination. For example, states and state transitions can be created to represent events such as patient motion during a scan (eg transition back to the same state to repeat the scan), different commands to perform a scan, etc. Each state is defined by a specific space for the value of the state variable (which can store patient parameters, imaging device par...

Abstract

An imaging system (10) includes: an image acquisition device (12), a device controller (16) comprising an electronic processor (20) programmed to operate the image acquisition device to acquire medical images of a patient and to maintain a machine log (26) storing an operating history of the image acquisition device; a server computer (34) programmed to retrieve patient information from at least one health information system (HIS) (18); and at least one feedback device (50, 52). The device controller, the server computer, or a combination of the device controller and server computer is programmed to implement at least one state machine (30, 44) having a plurality of states defined by values of state variables wherein the states represent respective attainable states of an image acquisitionprocedure (100) and the image acquisition device. The at least one state machine is configured to transition between states during the image acquisition procedure whereby the at least one state machine represents a current state of the image acquisition procedure and the image acquisition device, wherein the values of the state variables of the at least one state machine are determined based at least on content of the machine log for the image acquisition device and patient information retrieved by the server computer from the at least one HIS. The at least one feedback device is configured to provide guidance to an operator for performing the image acquisition procedure based on a current state of the at least one state machine.

Description

technical field [0001] The following relates to the field of medicine, the field of clinical decision support, the field of automated medical data analysis, and related fields. Background technique [0002] The difficulty in extending the use of complex medical imaging systems is the need for trained operators. Currently, developing countries (eg, Brazil) may not have access to complex imaging systems such as magnetic resonance (MR), computed tomography (CT), positron emission tomography (PET), single photon emission computed tomography (SPECT ), ultrasound (US), etc. Even if such countries have these systems, medical personnel in those countries may not have the proper training or skills to operate these devices. Although the problem is less severe in developed countries, the waiting period for medical imaging can still be long, which may be especially true in time-critical medical situations (for example, people with rapidly spreading cancer or who have suffered a fractu...
