Outcomes: What You’ll Be Able To Do in Radiographic Physics
Radiographic Physics bridges fundamental physics and clinical imaging. Strong tutoring builds both layers of understanding. These are observable outcomes, not guarantees.
Explain the production of X-rays at the anode — characteristic radiation and Bremsstrahlung — and predict how changes to kVp, mA, and exposure time affect the X-ray spectrum and patient dose. Analyse the interaction of X-ray photons with matter using the correct interaction model for the energy and tissue type — photoelectric effect, Compton scattering, coherent scattering — and connect these interactions to image contrast and radiation risk. Apply the principles of image quality — density, contrast, recorded detail, and distortion — to evaluate and optimise radiographic technique. Describe radiation protection principles accurately: ALARA, dose quantities (exposure, absorbed dose, effective dose), shielding calculations, and personnel monitoring. Interpret and apply the physics behind fluoroscopy, digital radiography, and computed tomography at the level expected in board exams and clinical coursework.

How My Physics Buddy Tutors Help You with Radiographic Physics (The Learning Loop)
Diagnose: Every engagement starts with a diagnostic. The tutor identifies which Radiographic Physics topic areas are secure, which are unclear, and where your problem-solving technique — particularly calculation-based questions on dose, HVL, and technique factors — is breaking down. This shapes every session.
Explain: Radiographic Physics connects abstract physics principles to visible clinical outcomes. Your tutor keeps that connection visible throughout — explaining why increasing kVp reduces contrast before working through the photoelectric vs Compton crossover, or what the half-value layer is physically telling you before applying the exponential attenuation formula. Explanations adapt until the concept is genuinely clear.
Radiation safety in diagnostic imaging is governed by guidelines from organisations including the National Council on Radiation Protection and Measurements (NCRP) and the International Commission on Radiological Protection (ICRP). Students who understand the physics behind these guidelines — rather than just memorising dose limits — are better equipped to apply them correctly in clinical situations and to adapt when circumstances vary.
Practice: You work through program-level questions live — X-ray tube rating calculations, HVL and attenuation problems, image quality technique adjustments, dose estimation, and shielding calculations. The tutor watches your reasoning at every step.
Feedback: After each problem, you get specific, targeted feedback. “Your attenuation calculation is correct but you used the linear attenuation coefficient where the question gives mass attenuation — divide by density first” or “your contrast analysis is right conceptually but you haven’t accounted for the grid ratio’s effect on the mAs correction” — precise and tied to what your program and board exam require.
Retest / Reinforce: Core ideas return in new problem contexts across sessions. The photoelectric effect, for instance, reappears in contrast discussions, dose calculations, shielding design, and kVp selection — each encounter reinforces the same underlying physics from a different clinical angle.
Plan: The tutor updates the session plan based on your course progression, upcoming tests, and board exam timeline. You always know what the next session targets and why.
Accountability: For students on weekly plans, tutors help maintain steady progress alongside clinical placement schedules and program deadlines.
Sessions run live on Google Meet with a digital pen-pad or iPad + Apple Pencil — useful for drawing tube diagrams, attenuation graphs, H&D curves, and CT geometry sketches in real time. Before your first session, share your program name, current unit or chapter, any recent test results, and your board exam date if relevant. The first session includes a short diagnostic, a live working-through of your most pressing topic, and a clear plan for the next two to four sessions.
Tutor Match Criteria (How We Pick Your Tutor)
Level and program fit: Your tutor will have direct experience with Radiographic Physics at your program level — associate degree RadTech programs, bachelor’s degree programs, or graduate medical physics content. They understand the clinical framing that radiography programs use and the board exam structure that students are working toward.
Topic strengths: If your difficulty is in X-ray production, image quality optimisation, digital imaging physics, CT dose, or radiation protection calculations, we match you with a tutor whose demonstrated expertise covers that area clearly.
Tools and setup: All MPB tutors use Google Meet and a digital pen-pad or iPad + Apple Pencil for real-time diagrams, calculation walkthroughs, and technique chart analysis.
Time zone and availability: Tutors are available across US, UK, Canada, Australia, and Gulf time zones, fitting around your program schedule, clinical rotations, and exam preparation timeline.
Learning style and pace: Some students need careful physics concept-building before approaching calculations. Others want rapid-fire board exam question practice. Your tutor adjusts the mode accordingly.
Goals: A student preparing for the ARRT board exam has different session needs than one working through a mid-semester physics course exam. We align on your goal before sessions begin.
Urgency and timeline: A student with a board exam in six weeks gets a focused, comprehensive review plan. A student starting a new semester gets a paced, week-by-week support structure. Tutor selection accounts for your timeline.
Study Plans (Pick One That Matches Your Goal)
MPB offers three broad plan types for Radiographic Physics: a catch-up plan (one to two weeks) for closing specific topic gaps before a program exam, an exam prep plan (four to eight weeks) for structured preparation toward a board exam or final course assessment, and an ongoing weekly support plan for students who want consistent guidance throughout their radiography program. The tutor builds the specific session plan after the diagnostic — no fixed schedule is set until your starting point, program level, and exam timeline are clearly understood.
Pricing Guide
Radiographic Physics tutoring at MPB starts at USD 20 per hour and typically ranges up to USD 40 per hour for most program-level sessions. For graduate Medical Physics content or highly specialised CT and fluoroscopy physics, rates may go higher — up to USD 100 per hour in some cases.
Pricing depends on the tutor’s experience, the depth of content covered, your program level, and session frequency. All rates are discussed transparently before you commit.
FAQ
Is Radiographic Physics hard?
Many radiography students find Radiographic Physics one of the more challenging courses in their program, particularly if their physics background is limited. The subject covers a wide range of concepts — from atomic structure and X-ray production to digital imaging and radiation protection calculations. With consistent, well-targeted support that connects the physics to clinical applications, most students find it manageable and genuinely interesting.
How many sessions are needed?
A student targeting specific weak areas — X-ray interactions or image quality calculations — may need four to eight sessions. A student seeking support across a full-semester Radiographic Physics course benefits from regular weekly sessions throughout the term. Students preparing for board exams typically benefit from a structured four to eight week plan. Your tutor will give a more precise estimate after the diagnostic.
Can you help with Radiographic Physics homework and assignments?
Yes — as guided support, not submission. Your tutor will work through problem approaches with you, explain where your reasoning breaks down, and help you build the understanding to complete the work independently. MPB does not complete or submit assignments for students. Students are expected to submit their own work at all times.
What happens in the first session?
The first session includes a short diagnostic on two or three topic areas, a live working-through of your most pressing concept or calculation problem, and a clear plan for the next two to four sessions. Come prepared with your current chapter or unit, any recent test results, your program’s assigned text, and any board exam dates. Sessions run on Google Meet with digital pen-pad support.
Can MPB help with ARRT board exam preparation?
Yes. The ARRT Radiography examination includes a significant physics content area covering radiation protection, equipment operation, and image production. MPB tutors familiar with the ARRT content specifications can structure sessions around the exam’s topic weightings and question style. Share your target exam date and your current weak areas and the tutor will build a focused preparation plan. Always verify current ARRT content specifications directly at arrt.org.
Is online tutoring effective for Radiographic Physics?
Yes. Radiographic Physics involves diagrams — X-ray tube schematics, attenuation curves, H&D curves, CT geometry — and calculations that a tutor can work through in real time on a digital pen-pad via Google Meet. The format is highly effective for this type of applied, visual subject. Research on personalised instruction, including findings discussed by the American Association of Physicists in Medicine (AAPM), supports the value of expert one-on-one guidance in medical physics education.
Can you help with lab reports or imaging practical assessments?
Yes, at a guidance level. Radiographic Physics practical work often involves measuring HVL, evaluating image quality parameters, or analysing technique charts. Your tutor can help you understand the physics behind your measurements, interpret your results, and structure your write-up clearly. MPB does not write reports for students.
What textbooks does MPB support for Radiographic Physics?
MPB tutors are familiar with the most commonly used texts in accredited radiography programs, including Bushong’s Radiologic Science for Technologists, Carlton & Adler’s Principles of Radiographic Imaging, and Bushberg et al.’s The Essential Physics of Medical Imaging. If your program uses a specific text, share it before the first session and the tutor will align sessions to it.
What is the difference between Radiographic Physics and Medical Physics?
Radiographic Physics is a program-level course for radiologic technologists and imaging students, focused on the practical physics of X-ray production, image formation, and radiation protection in clinical diagnostic imaging. Medical Physics is a graduate-level discipline covering a broader range of imaging modalities (MRI, nuclear medicine, radiation therapy) at a deeper mathematical and scientific level. Students pursuing Medical Physics at the graduate level can explore Medical Physics tutoring on MPB.
Does MPB cover other imaging modalities beyond X-ray radiography?
Yes. MPB supports related imaging and radiation science topics including Ultrasound Physics for sonography students, Radiation Physics for broader radiation science content, and Medical Physics for students working across multiple modalities at the graduate level.
Can you help radiography students who struggle with the underlying physics concepts?
Yes — and this is where 1:1 tutoring is most valuable. Many radiography students come from healthcare backgrounds rather than strong physics backgrounds. MPB tutors are experienced in building foundational physics understanding — atomic structure, electromagnetic radiation, energy and work — in the context of imaging, so that clinical applications make physical sense rather than being memorised in isolation. Students who want to strengthen their broader physics background can also explore Physics and Atomic Physics on MPB.
