Embodiments of the invention relate generally to the medical diagnostic equipment, and more specifically, to systems and methods for selecting a patient position and an equipment configuration for a medical procedure.
In the medical field there are often numerous pieces of mechanized diagnostic equipment deployed for use in patient care. Often, multiple pieces of equipment made by different manufacturers are employed by practitioners during the examination of a patient. In a typical arrangement, patient positioning equipment is coupled with the usage of diagnostic equipment, e.g., a mammogram device, dental x-ray machine, endoscopy, ultrasound guided biopsy practice, etc.
For example, the process of obtaining high quality mammographic images or biopsies from breast tissue generally requires a practitioner to orchestrate multiple pieces of equipment while also ensuring proper patient positioning, and equipment configuration. In particular, a practitioner may coordinate movements of a mammographic gantry, including lift, rotation, and angle. Further controls are required to control breast compression, imaging parameters (i.e., field of view, lighting, dosage); and in the case of ultrasound-guided biopsies, biopsy probe movement, suction controls, and ultrasonic imaging parameters. Patients are often positioned and supported during interventional mammographic procedures using mechanized chairs or tables.
In the case of a breast biopsy, a mammographic practitioner must account for the location of the lesion, the type of equipment available in the room, and the constraints upon such equipment in order to determine an optimal position for a patient to hold, as well as the correct configuration for the biopsy equipment used during a biopsy procedure.
Traditionally, a medical assistant must prepare the room prior to the patient's arrival. The assistant, however, must often wait for the patient to arrive at the room containing the medical equipment before knowing the patient's positional preferences, e.g., sitting or recumbent, for a particular procedure, e.g., a mammogram and/or biopsy procedure. Moreover, the medical assistant may not know the particular equipment configuration required, or preferred by the controlling entity of the medical equipment (e.g., the preferences of hospital staff), for the medical procedure to be performed, e.g., a vertical or horizontal approach for a biopsy needle. Further, the patient's position and/or the equipment configuration may be determined by the patient's morphology and/or lesion location, which may be unknown to the medical assistant.
Thus, medical assistants must often guess both the patient's desired position and/or the correct equipment configuration prior to the arrival of the patient and/or the preferences of the technologist/operator performing the medical procedure. As will be understood, however, incorrect guesses/assumptions by the medical assistant may require the medical equipment to be repositioned upon arrival of the patient and/or operator preforming the medical procedure, which in turn, generally decreases the efficiency of the medical procedure, e.g., increases the amount of time the patient, medical assistant, and/or operator performing the medical procedure, must spend in the room. In some instances, incorrect positioning of the patient and/or configuration of the medical equipment may result in a defective procedure, e.g., a biopsy needle may not reach its intended target, thus requiring the procedure to be re-started/redone. While many experienced medical assistants may be able to guess the correct patient position and/or equipment configuration for a particular procedure with a high rate of success, many inexperienced medical assistants will usually guess incorrectly.
What is needed, therefore, is an improved system and method for selecting a patient position and an equipment configuration for a medical procedure.
In an embodiment, a system for selecting a patient position and an equipment configuration for a medical procedure is provided. The system includes a controller, and a memory device operative to store an application. The application adapts the controller to retrieve, from the memory device, one or more possible patient positions for the medical procedure and one or more possible equipment configurations for the medical procedure. The application further adapts the controller to select, based at least in part on one or more parameters of the medical procedure, a patient position from the possible patient positions and an equipment configuration from the possible equipment configurations; and to generate an indicator that conveys the selected patient position and the equipment configuration.
In another embodiment, a method for selecting a patient position and an equipment configuration for a medical procedure is provided. The method includes retrieving, via a controller from a memory device, one or more possible patient positions for the medical procedure and one or more possible equipment configurations for the medical procedure. The method further includes selecting, via the controller and based at least in part on one or more parameters of the medical procedure, a patient position from the possible patient positions and an equipment configuration from the possible equipment configurations. The method further includes generating, via the controller, an indicator that conveys the selected patient position and the equipment configuration.
In yet another embodiment, a non-transitory computer readable medium storing instructions is provided. The stored instructions adopt a controller to retrieve, from a memory device, one or more possible patient positions for a medical procedure and one or more possible equipment configurations for the medical procedure. The stored instructions further adapt the controller to select, based at least in part on one or more parameters of the medical procedure, a patient configuration from the possible patient positions and an equipment configuration from the possible equipment configurations, and to generate an indicator that conveys the selected patient position and equipment configuration.
