this outcome is supported by mathematical computations and evaluations of the results. The paper also outlines and identifies potential advancements in the field such as the implementation of aSi-based EPIDs that can play a critical role in developing and aiding EPI systems in the near future. 1. Introduction The treatment of cancer by the means of radiation or exposure to a radioactive element requires further research to allow for the achievement and enhancement of pivotal objectives behind radiotherapy. According to Kirby and Glendinning (2006: pS50) advancements in radiotherapy must occur to explore solutions through which the dose that is aimed towards the target volume is enhanced such that the impact of high radiation on adjoining tissue, which is in a healthy state is lessened to a substantial extent. Pouliot et al. (2003: p862) state that in determining the exact location of the target volume the electron beams must be pointed in a precise direction to satisfy the requirements of a consistent dosimetric exposure. Piermattei et al. (2006) have presented a procedure which allows for the in vivo determination of the focal point of radiation that is tested on the target volume of pelvic regions. With regards to the accomplishment of aforementioned objectives and aims, enhancements in electronic portal imaging systems can play a critical role. Portal imaging essentially assists the geometric substantiation of field position (Kirby and Glendinning 2006: pS50) thereby, diminishing the possibility of geometric ambiguity (Pouliot et al. 2003: p862). According to Pouliot et al. (2003), the process of portal imaging aims to employ the assistance of bony landmarks to establish the placement and setup of the patient that is relative to the focal point of radiation, however, further considerations into the subject are required to direct researchers into the application and implementation of portal imaging systems in radiotherapy when discussing target volumes in soft tissue tumors of the prostate. The paper aims to discuss the advancements in portal imaging systems over the decades by assessing comprehensive literatures presented by Kirby and Glendinning (2006), Pouliot et al. (2003), Baker et al. (2005) and Piermattie et al. (2006), the primary focus of this assessment rests upon evaluating the technological innovations and developments in electronic portal imaging devices (EPIDs). Dedicated sections in the paper also discuss the use of radiopaque markers in the accurate visualization of the prostate via portal imaging to depict the accuracy of its placement throughout the procedure of radiotherapy by the means of a study conducted on a sample size of 11 patients. In conclusion the paper reviews and appraises the advancements in the development of electronic portal imaging systems by assessing the literature under review and stating that the developments in e
The Role of Electronic Portal Imaging Systems in Radiation Oncology Abstract Since the emergence of electronic portal imaging (EPI) systems towards the end of the 1950s, several advancements in the field have significantly contributed towards shaping the effectiveness of portal imaging in patient positioning that must be performed accurately before the commencement of radiotherapy…
Advances and further researches are still going in the field of the MRI to improve the quality of the images by increasing magnetic strength. The question about MRI’s significance is still being debated by Max P. Rosen, MD, and MPH, a radiologist at Beth Israel Deaconess Medical Center in Boston and his colleagues.
Using Lean Six Sigma to Improve Hospital based, Outpatient Imaging Satisfaction
A typical healthcare institute like Methodist Willow-Brook attends to three types of patients: outpatients, inpatients and emergency patients. Since, the hospital uses the same equipments for all types of patients; therefore, the imaging department is uncertain as to who shall be prioritized when it comes to serving the patient.
These traditional systems of delivery were restricted to single point delivery and 2-Dimensional plane deliveries which are not adequate for the highly complex contemporary requirements of delivery. In an effort to curb this menace, work has been done on a new system which has highly promising results.
Based on this principle, an external counter may detect the radioactivity and create an image of the thyroid gland. Pertechnetate is another radionuclide which can also be used in a similar fashion to detect the activity of the gland. In clinical practice different hyperthyroid conditions such as Graves' disease, hyperthyroid goiter, and other conditions such as toxic multinodular or nodular goitre need assessment of activity of the gland.
At the beginning of the process the ordering physician's office calls the respective imaging areas such as CT, MRI, or other radiology exam areas to schedule a patient exam. At this time the radiology outpatient receptionist in the imaging area schedules the appointment for the appropriate date and time.
ck radiology assessment as diagnostic aids for diagnosis and initiation of therapeutic interventions, and the discontent among radiographers with their limited responsibilities (Rudd, 2003).
This led to the concept of creating additional knowledge and skills among experienced
This implies that the patients can get information regarding their diets, exercises easily. The information is kept organized in an online database. This saves the patient time as well as the staff’s time.
Patient’s portals within an EMR system also
