HKSH Presenting Recent Findings on PCCT-Sim at International Conferences

HKSH is actively leveraging PCCT-Sim to further optimise proton therapy dose calculation and tumour target delineation. By integrating cutting-edge technologies like PCCT with clinical needs, HKSH not only delivers supreme medical services to patients in Hong Kong SAR but also aims to set new benchmarks for innovative applications of medical technology worldwide. Relevant clinical data and research findings will be presented at major international radiotherapy conferences, including the European Society for Radiotherapy and Oncology (ESTRO) Congress in Sweden this May and the Particle Therapy Co-Operative Group (PTCOG) annual meeting staged in France this June, contributing to global medical research and innovation.

PCCT-Sim utilises cadmium telluride crystal detector technology, directly converting X-ray photons into electrical signals to deliver unprecedented image detail and spectral information with up to 70% reduction in radiation dose. PCCT-Sim overcomes the limitations of conventional CT, including suboptimal contrast resolution, artifacts, and the inability to provide functional information. With its superior spatial and contrast resolution, PCCT produces ultra-high spatial resolution images which enable extremely precise delineation of tumours and surrounding healthy tissues.

In proton therapy, PCCT can calculate the position of the Bragg peak much more accurately, reducing uncertainties in dose calculation and thereby improving treatment effectiveness. In advanced radiotherapy techniques such as intensity‑modulated or stereotactic radiotherapy, precise target delineation is crucial, especially for very small or structurally complex lesions, and the excellent tissue differentiation of PCCT helps minimise contouring errors in the tumour region. This could prevent an underdose in the tumour region, or an overdose to surrounding healthy organs which may compromise treatment efficacy or increase the risk of radiation-induced toxicity. The integration of PCCT into clinical practice promises to achieve safer and more personalised precision cancer treatment.

Committed to world-class treatment standards, HKSH Cancer Centre has taken the lead to introduce the Greater Bay Area's first proton therapy system and continues to pursue ever-higher precision in its delivery. As the most advanced form of radiotherapy, proton therapy requires unparalleled precision to maximise therapeutic effectiveness while minimising radiation-induced side effects. "To further reduce the number of treatment sessions and improve efficacy, extremely precise imaging technology is the cornerstone for minimising treatment uncertainties. That is why HKSH has fully embraced PCCT-Sim, an ultra-precise simulation and positioning technology which is the future of computed tomography. PCCT-Sim will create powerful synergies with proton therapy, advancing cancer management to new heights," remarked Mr. LI.

HKSH Medical Group Named Asia's first Photon-Counting CT Simulator Reference Site, Bringing Global Impacts on Precision Medicine and Medical Imaging with Siemens Healthineers

LOS ANGELES, June 13, 2026 /PRNewswire/ -- Southern California homeowners are facing longer hot seasons, rising utility costs, and evolving lifestyle needs. As a result, demand for flexible, energy-efficient cooling solutions continues to rise across the region with no signs of slowing down.

DELLA, a leading provider of ductless mini split systems, is helping homeowners meet these changing demands with smart, room-specific cooling solutions. As modern households seek greater comfort, convenience, and energy efficiency, ductless systems offer an effective alternative to relying solely on traditional whole-home climate control.

The Shift Toward Smarter Home Climate Control

This pronounced shift reflects a growing trend reshaping home comfort. Today's homeowners are no longer focused only on keeping a house cool. Increasingly, they want personalized comfort that adapts to how different rooms are being used throughout the day.

Modern smart homes no longer function as a single environment with a uniform temperature. Climate fluctuates naturally throughout the day based on a variety of factors, and each room serves a completely different purpose.

Yet many traditional HVAC systems continue to cool the entire household as though every room and every person require the same temperature.

To remedy this, homeowners across Southern California are exploring room-by-room climate control solutions that provide greater flexibility and efficiency.

Why Traditional Central AC Often Feels Inconsistent

Most central air systems were designed around a simple old-fashioned idea: one thermostat controls the entire home. But modern living has changed dramatically.

Different rooms heat up differently based on sunlight, layout, occupancy, electronics, cooking activity, ceiling height, and even the time of day. The result is a home that constantly feels slightly off balance.

Common frustrations include:

• Bedrooms that stay warm long after sunset
• Overcooled living rooms during the day
• Upstairs areas that never feel comfortable
• Constant thermostat adjustments
• Rising summer energy bills without better comfort

The issue isn't always that a system is failing—it's that the system was designed for an older idea of how homes function.

Today, homeowners are searching for energy efficient cooling systems that support room-by-room living rather than treating the home as a single environment.

Because real comfort is not just about what the thermostat says.

It's about how a home actually feels.

This is why DELLA provides energy efficient cooling systems that adapt to how people actually live instead of forcing one fixed temperature across the entire home.

How DELLA Mini Split Systems Address Changing Homeowner Needs

DELLA mini split systems were designed around the growing demand for personalized comfort and more efficient cooling.

Instead of pushing air through extensive ductwork from a single central source, mini split systems deliver targeted comfort directly into individual rooms. Each indoor unit operates independently, allowing temperatures to adjust naturally based on how each space is being used.

That flexibility changes the entire home comfort experience.

Rather than overcooling one area to compensate for another, homeowners can create balanced comfort throughout the home in a way that feels quieter, more efficient, and better aligned with daily routines.

This is one reason ductless mini splits and smart climate systems continue gaining popularity throughout Southern California, particularly during extended periods of summer heat.

The goal is no longer simply more air conditioning.

It is smarter comfort that works in the background while adapting naturally to everyday life.

Key advantages include:

• Room-by-room temperature control
• Faster cooling response times
• Lower energy waste compared to traditional ducted systems
• Quiet air conditioner performance for bedrooms and living spaces
• Flexible installation without major renovation work
• More balanced airflow throughout the home

For many homeowners, the biggest difference is how natural the comfort feels.

The best climate systems don't constantly remind you they're running. They quietly support the way people actually live.

Homes Aren't One Temperature Anymore

A bedroom may require cooler nighttime temperatures for improved sleep quality.

A home office may need consistent daytime cooling during work hours.

A kitchen naturally generates heat during cooking.

Living rooms may fluctuate based on gatherings, sunlight exposure, entertainment equipment, and daily activity.

Traditional HVAC systems often struggle to respond to these changing conditions because they treat the entire house as a single cooling zone.

That is where zoned cooling for homes becomes a significant advantage.

Mini split systems allow homeowners to cool spaces individually rather than forcing a single setting throughout the home. The result is more precise comfort, improved efficiency, and a living environment that better reflects how people use their homes today.

The DELLA Mini Split Collection

DELLA offers a complete collection of ductless cooling systems designed to adapt to virtually any lifestyle, home layout, or comfort preference. Three of the company's most popular models — the Serena, Optima, and Vario Series — each deliver a different approach to modern comfort while emphasizing efficiency, quiet performance, and flexible everyday living.

The Serena Series focuses on balanced whole-home comfort with smooth, quiet operation and up to 22 SEER2 efficiency, making it an ideal choice for consistent daily use.

The Optima Series is designed for multi-zone precision, allowing homeowners to independently control temperatures in different rooms for greater comfort and improved efficiency throughout the home.

Meanwhile, the Vario Series offers a practical and budget-conscious solution for targeted cooling in bedrooms, home offices, garage conversions, apartments, and ADUs.

Together, these systems reflect DELLA's broader approach to smart, adaptable comfort built around the way modern homeowners actually live.

Quiet Comfort Is the New Luxury

One of the biggest changes happening in modern home comfort is that homeowners are becoming more sensitive to how cooling feels — not just whether cold air exists.

Older systems often rely on aggressive airflow, loud cycling, or constant thermostat adjustments that make the cooling experience feel noticeable and disruptive.

But modern comfort trends are shifting toward quieter, more balanced environments.

People want bedrooms that stay cool without loud airflow at night.

They want living spaces that feel evenly comfortable without cold blasts of air hitting one side of the room.

They want systems that operate quietly in the background while daily life continues naturally.

This is why mini split systems are increasingly viewed as both a lifestyle upgrade and an efficiency upgrade.

DELLA's technology supports a softer, more adaptive approach to cooling that aligns with how modern homes are actually being used.

Energy Efficiency That Supports Everyday Living

Energy savings remain one of the strongest practical advantages of mini split systems.

Unlike traditional HVAC systems that repeatedly cycle on and off, inverter technology continuously adjusts output to maintain stable temperatures more efficiently.

This leads to:

• Lower monthly utility costs
• Reduced energy waste
• More stable indoor temperatures
• Less system strain over time
• Improved long-term efficiency performance

For homeowners dealing with Southern California summers, those efficiency gains often become noticeable quickly, especially during extended heat waves when cooling systems run for longer periods throughout the day.

Southern California Home Comfort

Real comfort is about creating spaces that feel balanced, natural, and comfortable exactly where and when you need them most. DELLA provides homeowners, especially those in areas with hot climates like Southern California, with all the right options to save money, conserve energy, and stay truly comfortable.
