Abstract

A multi-modality medical system having a computing system communicatively coupled to a medical instrument is provided. An acquisition control activity module is configured to control acquisition of medical data from a patient with the medical instrument and a business logic state machine having a first data acquisition state and a first data review state and being operable to utilize the acquisition control activity module to control acquisition of medical data from the patient with the medical instrument while in the first data acquisition state, and being configured to convert the medical data into images representative of portions of the patient while in the first data acquisition state. The computing system includes also includes a user interface state machine having a second data acquisition state and a second data review state and being configured to present the images within a user interface while in the second data review state.

First claim

What is claimed is:

1. A multi-modality medical system, comprising:
an intravascular ultrasound (IVUS) catheter sized and shaped for positioning within a vessel of a patient and including a transducer and configured to obtain IVUS data associated with an IVUS modality;
a medical instrument different than the IVUS catheter and configured to obtain medical data of a modality different than IVUS modality; and
a computing system communicatively coupled to the IVUS catheter and the medical instrument, the computing system including:
a plurality of activity modules configured to perform acquisition workflows, wherein the plurality of activity modules includes an energize activity module, a start pullback activity module, and a stop pullback activity module;
a first business logic state machine configured to control acquisition of the IVUS data from the patient with the IVUS catheter while the IVUS catheter is positioned within the vessel of the patient, wherein the first business logic state machine comprises an imaging ready state, the first business logic state machine entering the imaging ready state in response to coupling the IVUS catheter to the computing system, wherein the imaging ready state includes an IVUS imaging sub-state utilizing the plurality of activity modules, wherein, while the first business logic state machine is in the IVUS imaging sub-state:
in response to execution of the energize activity module, the computing system energizes the transducer of the IVUS catheter to obtain the IVUS data within the vessel,
in response to execution of the start pullback activity module, the computing system starts pullback of the IVUS catheter within the vessel, and
in response to execution of the stop pullback activity module, the computing system stops pullback of the IVUS catheter within the vessel; and

a second business logic state machine different than the first business logic state machine and configured to control acquisition of the medical data from the patient with the medical instrument, the second business logic state machine comprising one or more states utilizing the plurality of activity modules;
wherein the first and second business logic state machines each comprise a hierarchical sequence of actions executable using one or more of the plurality of activity modules to respectively control acquisition of the IVUS data and the medical data; and
wherein the plurality of activity modules is implemented in the computing system independently of the first and second business logic state machines such that each of the first and second business logic state machines can execute a same activity module during the respective hierarchical sequences of actions of the first and second business logic state machines to control the acquisition of the IVUS data with the IVUS catheter and to control the acquisition of the medical data with the medical instrument.

2. The multi-modality medical system of claim 1 , wherein the computing system further includes an acquisition control activity module that is implemented independent of the first business logic state machine and the second business logic state machine.

3. The multi-modality medical system of claim 2 ,
wherein the first business logic state machine is configured to utilize the acquisition control activity module to control acquisition of the IVUS data from the patient with the IVUS catheter; and
wherein the second business logic state machine is configured to utilize the acquisition control activity module to control acquisition of the medical data from the patient with the medical instrument.

4. The multi-modality medical system of claim 2 , wherein the acquisition control activity module is operable to perform at least one of energizing the transducer of the IVUS catheter, starting pullback of the IVUS catheter, and stopping pullback of the IVUS catheter.

5. The multi-modality medical system of claim 1 , further comprising:
a first user interface state machine configured to receive the IVUS data from the first business logic state machine and present the IVUS data within a user interface, wherein the first user interface state machine comprises a live display state and a review full motion display state, wherein the first user interface state machine is operable to transition into the live display state during acquisition of the IVUS data and is operable to transition into the review full motion display state after acquisition of the IVUS data; and
a second user interface state machine configured to receive the medical data from the second business logic state machine and present the medical data within the user interface, wherein the second user interface state machine comprises a live display state and a review full motion display state, wherein the second user interface state machine is operable to transition into the live display state during the acquisition of the medical data and is operable to transition into the review full motion display state after acquisition of the medical data,
wherein the imaging ready state includes an initial sub-state defining a transition of the first business logic state machine to the IVUS imaging sub-state or another sub-state of the imaging ready state when the first business logic state machine enters the imaging ready state.

6. The multi-modality medical system of claim 5 , wherein the computing system further includes an interface rendering activity module.

7. The multi-modality medical system of claim 6 ,
wherein the first user interface state machine is configured to utilize the interface rendering activity module to present the IVUS data within the user interface; and
wherein the second user interface state machine is configured to utilize the interface rendering activity module to present the medical data within the user interface.

8. The multi-modality medical system of claim 6 , wherein the interface rendering activity module is operable to perform at least one of rendering an acquisition screen and rendering a review screen.

9. The multi-modality medical system of claim 6 , wherein the interface rendering activity module is operable to perform at least one of adding a measurement to an image, adding an annotation to an image, and adding a label to an image.

10. The multi-modality medical system of claim 1 , wherein the modality of the medical data includes one of intravascular photoacoustic (IVPA) imaging, optical coherence tomography (OCT), fractional flow reserve (FFR), angiography, or coronary flow reserve (CFR).

11. The multi-modality medical system of claim 5 , wherein the first business logic state machine includes a data acquisition state and a data review state.

12. The multi-modality medical system of claim 11 , wherein the first business logic state machine is operable to transition between the data acquisition state and the data review state based on user actuations of elements within the user interface.

13. The multi-modality medical system of claim 5 ,
