Project Design and Proposal Development

Why a Formal Proposal Matters

A capstone project is not simply a report you write at the end of your training. It is a structured demonstration that you can identify a real clinical problem, plan a safe and ethical investigation, and apply the knowledge you have built across every course in this program. Before any data are collected or any procedure is observed, you must have a written, faculty-approved proposal. This gate exists for the same reason informed consent exists in patient care: it ensures that every step has been reviewed, risks have been considered, and the work is within your scope of practice before anything irreversible happens.

Choosing a Clinically Grounded Topic

A strong capstone topic solves—or at least illuminates—a real problem that a radiologic department actually faces. Common examples include repeat-rate reduction (why are certain projections being retaken, and what can be done about it?), patient positioning accuracy (are lateral chest images consistently showing true laterals?), and quality control trend analysis (are sensitometry logs showing processor or detector drift over time?). Your topic must connect clearly to at least one ARRT content area: radiation protection, image production, patient care, or equipment quality control.

Avoid topics that are purely theoretical with no departmental application, and avoid topics that would require you to perform procedures outside your authorized scope of practice or to expose patients to ionizing radiation for research purposes without proper institutional approval. If you are unsure whether your idea stays within scope, check the ARRT content specifications for Limited Scope and Radiography (RT-R) and consult your clinical site supervisor or faculty before investing time in a full draft.

The PICO-Style Problem Statement

Your proposal centers on a problem statement written in PICO format, adapted from evidence-based practice in the health professions:

• P – Population: Who or what is affected? (e.g., adult outpatients receiving chest radiographs at a community clinic)
• I – Issue: What is the problem or intervention being examined? (e.g., a high repeat rate on lateral chest projections)
• C – Comparison: What is the current practice or the baseline you are comparing against? (e.g., current positioning technique versus a structured positioning checklist)
• O – Outcome: What measurable result are you looking for? (e.g., a reduction in repeat rate as tracked by the department's reject-analysis log)

A PICO statement keeps your project focused. A vague problem statement produces vague data and an inconclusive conclusion. Write your PICO statement in two or three sentences, then test it: if someone outside radiology can read it and immediately understand what you are studying and why it matters, it is clear enough.

Rationale and Scope-of-Practice Justification

After the problem statement, your proposal must explain why this problem matters clinically and how your role as a limited or entry-level radiologic technologist connects to it. Reference professional standards where relevant. For example, radiation protection is both an ARRT content area and a federal and state regulatory concern under ionizing radiation standards. If your project involves reviewing QC logs, explain that equipment quality control is part of every radiographer's daily responsibility and that your proposed analysis remains within the observation and documentation role appropriate to your credential level.

The Safety and Ethics Checklist

Every proposal must include a signed safety checklist confirming:

1. The project involves no unapproved patient radiation exposure. Data collection uses existing records, phantoms, retrospective logs, or direct observation only—never additional imaging performed solely for research.

2. Patient information used in any data review is handled in compliance with privacy regulations, with patient identifiers removed or access supervised by a licensed practitioner.

3. The project does not require the student to perform procedures beyond their authorized scope of practice at the clinical site.

4. Any equipment used for demonstration or QC testing follows the site's established protocols.

This checklist is not a formality. Violating any of these points exposes patients to harm, exposes the clinical site to liability, and can jeopardize your eligibility for licensure and ARRT certification. Faculty will not approve a proposal that cannot satisfy all four conditions.

Timeline and Methodology

Your draft timeline should list specific milestones: when you will collect data, when a draft analysis will be complete, and when the final project will be submitted. Realistic timelines account for the fact that clinical sites have busy periods, records may need retrieval time, and analysis takes longer than expected. Build in at least one checkpoint with your faculty mentor.

Your methodology section describes exactly how data will be gathered and recorded. If you are reviewing reject-analysis logs, state how many weeks of logs, from which modality, and how you will categorize repeat reasons. If you are conducting a positioning accuracy audit using phantom images, describe the phantom, the projections, and the criteria you will use to judge accuracy. Vague methodology produces results that cannot be trusted.

References and Academic Integrity

Your proposal must include at least five current radiologic science sources. Peer-reviewed journals, current editions of standard references such as Merrill's Atlas or Bushong's Radiologic Science for Technologists, and ARRT content specifications are all appropriate. Format citations in APA or AMA style as directed by your program. Citing sources shows that your project is grounded in established knowledge, not guesswork, and it is the same habit that will serve you when you pursue continuing education requirements throughout your career.

The Verbal Pitch and Peer Review

Before final submission, you will present a five-minute verbal summary of your proposal to the class. This step is not a performance—it is a quality-control measure. Colleagues who have been studying the same material you have may spot a safety gap, a scope-of-practice concern, or a methodology flaw that you missed. Incorporate useful feedback, then submit the revised proposal through the LMS portal. Faculty approval in writing is required before you may advance to data collection.
