Home monitoring prevents hospital admissions 

• Telehealth devices track vital signs at home for chronic disease patients. This works by alerting healthcare workers to changes before emergencies occur.
• Supporting the use of this technology is a CSIRO telehealth trial that showed hospital admissions were reduced by over 50% for users.
• This creates significant cost savings given a hospital bed overnight stay costs around $2000.

Early intervention shortens hospital stays

• Remote monitoring enables doctors to detect problems quickly. This happens because devices can communicate real-time data about measurements such as heart rate, oxygen levels, and blood pressure.
• Consequently, if patients do need hospitalisation, stays are much shorter.
• This in turn frees up beds for other patients.

Technology reduces healthcare visits

• Patients manage conditions from home using monitoring equipment. This leads to fewer GP visits, specialist appointments, and procedures.
• The reason for this is that continuous monitoring generates better disease management.
• Therefore, healthcare professionals can focus on patients who need immediate care.
• This demonstrates why the return on investment into remote monitoring technology is estimated at 5:1.

Early detection enables timely treatment.

• PET scans, for example, identify abnormal cell activity before symptoms appear. This occurs because these scans detect metabolic changes at cellular level.
• As a result, doctors can start treatment when diseases are most responsive. This leads to higher survival rates and better prognosis.

Precise identification prevents disease progression.

• The ACEMID system uses 92 cameras to create 3D body models that identify every mole within 1 second. This works by detecting minute changes in size or appearance.
• Consequently, melanomas are caught before spreading.
• This triggers immediate medical intervention, which means that cancer doesn’t advance to dangerous stages.

Comprehensive imaging reduces misdiagnosis

• Advanced scanning generates detailed internal views. This process ensures doctors see exactly what’s happening inside the body.
• Therefore, treatment plans target the actual problem. This in turn prevents unnecessary procedures and reduces patient stress.
• The underlying reason is that accurate diagnosis creates appropriate treatment pathways from the start.

• B is correct. 3D models improve cardiac diagnosis by giving detailed visualisation of internal heart anatomy, helping doctors identify issues.

Other options:

• A is incorrect. Holographic models complement, rather than replace, other diagnostic tools such as CT, PET, or MRI scans.
• C is incorrect. The main benefit is not viewing external features, but understanding internal cardiac structures.
• D is incorrect. While these models can improve patient understanding, their primary role is improving diagnostic accuracy.

• B is correct. The ACEMID system uses 92 cameras to create a 3D body model (avatar) that identifies, maps and measures moles, enabling early detection of melanoma.

Other options:

• A is incorrect. While high-resolution photos assist dermatologists, ACEMID provides more comprehensive body-wide imaging, not just individual mole photographs.
• C is incorrect. ACEMID is a diagnostic tool used by professionals, not primarily designed for self-examination.
• D is incorrect. Although advanced imaging software can compare mole changes, ACEMID’s key contribution is its 3D whole-body modelling.

• C is correct. The ACEMID system creates a 3D body avatar using high-resolution imaging to detect and track moles.

Other options:

• A is incorrect. Oxygen saturation levels are measured using pulse oximeters, not the ACEMID system.
• B is incorrect. Sleep cycle irregularities are tracked with apps and wearable devices.
• D is incorrect. Robotic movements are linked to precision surgery.

• B is correct. 3D holographic heart imaging provides greater clarity of anatomical structures, allowing doctors to make more accurate diagnoses and plan effective treatment.

Other options:

• A is incorrect. Improved post-surgical recovery rates result from effective treatment and precision surgery, not directly from imaging.
• C is incorrect. Robotic procedures still require surgeon involvement.
• D is incorrect. Health promotion remains vital regardless of imaging technology as it addresses prevention.

• A is correct. A PET scan is commonly used for the early detection of cancer, as it identifies abnormal metabolic activity associated with tumour growth.

Other options:

• B is incorrect. Fitness trackers measure steps, heart rate, and activity but cannot detect cancer.
• C is incorrect. Ultrasound imaging can assist in identifying some abnormal growths but is not a primary tool for early cancer detection compared to PET scans, CT scans, or MRI.
• D is incorrect. Sleep apps track sleep behaviours and patterns, not disease detection.
